1.    BASIS OF PRESENTATION

Southwest Airlines Co. (the "Company" or "Southwest") operates Southwest Airlines, a major passenger airline that provides scheduled air transportation in the United States and near-international markets. The unaudited Condensed Consolidated Financial Statements include accounts of the Company and its wholly owned subsidiaries.

In late December 2022, the Company experienced a wide-scale operational disruption as historically extreme winter weather across a significant portion of the United States impacted its operational plan and flight schedules. Subsequent to Winter Storm Elliott, the Company was challenged to realign flight crews, flight schedules, and aircraft for a period of several days during this peak demand travel period. This disruption and subsequent recovery efforts resulted in the cancellation of more than 16,700 flights during the period from December 21 through December 31, 2022. These events also created a deceleration in bookings, primarily isolated to January and February 2023, as well as increased first quarter 2023 expenses by approximately $55 million, which are included in the accompanying unaudited Condensed Consolidated Statement of Comprehensive Income (Loss) for the sixnine months ended JuneSeptember 30, 2023. These first quarter 2023 expenses included reimbursements to Customers impacted by the cancellations for costs they incurred in excess of the amounts accrued as of December 31, 2022, adjustments to the estimated value of Rapid Rewards points offered as a gesture of goodwill to Customers as a result of changes in the estimates of the points expected to be redeemed, and additional premium pay and additional compensation for Employees directly or indirectly impacted by the cancellations and recovery efforts. There were no material impacts to operating revenues or expenses for the three months ended June 30,beyond first quarter 2023 as a result of this disruption.

The accompanying unaudited Condensed Consolidated Financial Statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the United States ("GAAP") for complete financial statements. The unaudited Condensed Consolidated Financial Statements for the interim periods ended JuneSeptember 30, 2023 and 2022 include all adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. This includes all normal and recurring adjustments and elimination of significant intercompany transactions. Financial results for the Company and airlines in general can be seasonal in nature. In many years, the Company's revenues, as well as its Operating income and Net income, have beenperformed better in its second and third fiscal quarters than in its first and fourth fiscal quarters. Air travel is also significantly impacted by general economic conditions, the amount of disposable income available to consumers and changes in consumer behavior, unemployment levels, corporate travel budgets, global pandemics such as COVID-19, extreme or severe weather and natural disasters, fears of terrorism or war, governmental actions, and other factors beyond the Company's control. These and other factors, such as the price of jet fuel in some periods, the nature of the Company's fuel hedging program, and the periodic volatility of commodities used by the Company for hedging jet fuel, have created, and may continue to create, significant volatility in the Company's financial results. See Note 3 for further information on fuel and the Company's hedging program. Operating results for the three and sixnine months ended JuneSeptember 30, 2023, are not necessarily indicative of the results that may be expected for future quarters or for the year ended December 31, 2023. For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022.
Certain prior period amounts have been reclassified to conform to the current presentation. In the unaudited Condensed Consolidated Statement of Comprehensive Income for the three and six months ended June 30, 2022, the Company has reclassified $43 million and $116 million from Other (gains) losses, net to Loss on extinguishment of debt.

2.    NEW ACCOUNTING PRONOUNCEMENTS

On January 7, 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848). This new standard provides optional temporary guidance for entities transitioning away from London Interbank Offered Rate

("LIBOR") to new reference interest rates so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions with Topic 848. These amendments do not apply to any contract modifications made after December 31, 2024, any new hedging relationships entered into after December 31, 2024, or to existing hedging relationships evaluated for effectiveness existing as of December 31, 2024, that apply certain optional practical expedients. This standard was effective immediately and may be applied (i) on a full retrospective basis as

of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or (ii) on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final update, up to the date that financial statements are available to be issued. The Company had no material LIBOR-related contract modifications during the sixnine months ended JuneSeptember 30, 2023.

3.    FINANCIAL DERIVATIVE INSTRUMENTS

Fuel Contracts
Airline operators are inherently dependent upon energy to operate and, therefore, are impacted by changes in jet fuel prices. Furthermore, jet fuel and oil typically represents one of the largest operating expenses for airlines. The Company endeavors to acquire jet fuel at the lowest possible cost and to reduce volatility in operating expenses through its fuel hedging program.

The Company has used financial derivative instruments for both short-term and long-term timeframes, and primarily uses a mixture of purchased call options, collar structures (which include both a purchased call option and a sold put option), call spreads (which include a purchased call option and a sold call option), put spreads (which include a purchased put option and a sold put option), and fixed price swap agreements in its portfolio. The Company does not purchase or hold any financial derivative instruments for trading or speculative purposes.

For the purpose of evaluating its net cash spend for jet fuel and for forecasting its future estimated jet fuel expense, the Company evaluates its hedge volumes strictly from an "economic" standpoint and thus does not consider whether the hedges have qualified or will qualify for hedge accounting. The Company defines its "economic" hedge as the net volume of fuel derivative contracts held, including the impact of positions that have been offset through sold positions, regardless of whether those contracts qualify for hedge accounting. The level at which the Company is economically hedged for a particular period is also dependent on current market prices for that period, as well as the types of derivative instruments held and the strike prices of those instruments. For example, the Company may enter into "out-of-the-money" option contracts (including "catastrophic" protection)protection, which the Company defines as prices significantly higher than historical average levels), which may not generate intrinsic gains at settlement if market prices do not rise above the option strike price. Therefore, even though the Company may have an economic hedge in place for a particular period, that hedge may not produce any hedging gains at settlement and may even produce hedging losses depending on market prices, the types of instruments held, and the strike prices of those instruments.

As of JuneSeptember 30, 2023, the Company had fuel derivative instruments in place to provide coverage at varying price levels. The following table provides information about the Company’s volume of fuel hedging on an economic basis:

(a) Due to the types of derivatives utilized by the Company and different price levels of those contracts, these volumes represent the maximum economic hedge in place and may vary significantly as market prices and the Company's flight schedule fluctuate.

Upon proper qualification, the Company accounts for its fuel derivative instruments as cash flow hedges. Qualification is re-evaluated quarterly, and all periodic changes in fair value of the derivatives designated as hedges

are recorded in Accumulated other comprehensive income ("AOCI") until the underlying jet fuel is consumed. See Note 4.

When the Company has sold derivative positions in order to effectively "close" or offset a derivative already held as part of its fuel derivative instrument portfolio, any subsequent changes in fair value of those positions are marked to market through earnings. Likewise, any changes in fair value of those positions that were offset by entering into the sold positions and were de-designated as hedges are concurrently marked to market through earnings. However, any changes in value related to hedges that were deferred as part of AOCI while designated as a hedge would remain until the originally forecasted transaction occurs. In a situation where it becomes probable that a fuel hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. The Company did not have any such situations where a derivative ceased to qualify for hedge accounting during 2022, or during the sixnine months ended JuneSeptember 30, 2023.

All cash flows associated with purchasing and selling fuel derivatives are classified as Other operating cash flows in the unaudited Condensed Consolidated Statement of Cash Flows. The following table presents the location of all assets and liabilities associated with the Company’s derivative instruments within the unaudited Condensed Consolidated Balance Sheet:

instruments the Company has determined are subject to netting requirements in the accompanying unaudited Condensed Consolidated Balance Sheet are those in which the Company pays or receives cash for transactions with the same counterparty and in the same currency via one net payment or receipt. For cash collateral held by the Company or provided to counterparties, the Company nets such amounts against the fair value of the Company's derivative portfolio by each counterparty. The Company has elected to utilize netting for both its fuel derivative instruments and interest rate swap agreements and also classifies such amounts as either current or noncurrent, based on the net fair value position with each of the Company's counterparties in the unaudited Condensed Consolidated Balance Sheet. If its fuel derivative instruments are in a net asset position with a counterparty, cash collateral amounts held are first netted against current outstanding derivative asset amounts associated with that counterparty until that balance is zero, and then any remainder is applied against the fair value of noncurrent outstanding derivative instruments. As of JuneSeptember 30, 2023, no cash collateral deposits were provided by or held by the Company based on its outstanding interest rate swap agreements.

The Company had the following recognized financial assets and financial liabilities resulting from those transactions that meet the scope of the disclosure requirements as necessitated by applicable accounting guidance for balance sheet offsetting:

The fair values of the derivative instruments, depending on the type of instrument, were determined by the use of present value methods or option value models with assumptions about commodity prices based on those observed in underlying markets or provided by third parties. Included in the Company’s cumulative unrealized lossesgains from fuel hedges as of JuneSeptember 30, 2023, recorded in AOCI, were approximately $13$77 million in unrealized losses,gains, net of taxes, which are expected to be realized in earnings during the twelve months subsequent to JuneSeptember 30, 2023.

Interest Rate Swaps
The Company is party to certain interest rate swap agreements that are accounted for as cash flow hedges. The Company did not have any interest rate swap agreements designated as fair value hedges, as defined, during the periods presented. All of the Company's interest rate swap agreements qualify for the "shortcut" or "critical terms match" methods of accounting for hedges, which dictate that the hedges were assumed to be perfectly effective at origination, and, thus, there was no ineffectiveness to be recorded in earnings.

Credit Risk and Collateral
Credit exposure related to fuel derivative instruments is represented by the fair value of contracts that are an asset to the Company at the reporting date. At such times, these outstanding instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the agreements. However, the Company has not experienced any significant credit loss as a result of counterparty nonperformance in the past. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings, limits its exposure with respect

to each counterparty, and monitors the market position of the fuel hedging program and its relative market position with each counterparty. As of JuneSeptember 30, 2023, the Company had agreements with all of its active counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount based on the counterparty's credit rating. The Company also had agreements with counterparties in which cash deposits and letters of credit were required to be posted as collateral whenever the net fair value of derivatives associated with those counterparties exceeds specific thresholds. In certain cases, the Company has the ability to substitute among these different forms of collateral at its discretion.

5.    REVENUE

Passenger Revenues

The Company’s contracts with its Customers primarily consist of its tickets sold, which are initially deferred as Air traffic liability. Passenger revenue associated with tickets is recognized when the performance obligation to the Customer is satisfied, which is primarily when travel is provided.

Revenue is categorized by revenue source as the Company believes it best depicts the nature, amount, timing, and uncertainty of revenue and cash flow. The following table provides the components of Passenger revenue recognized for the three and nine months ended September 30, 2023 and 2022:

On July 28, 2022, the Company announced that all existing Customer flight credits as of that date, as well as any future flight credits issued, will no longer expire and will thus remain redeemable by Customers. Flight credits for non-refundable fares will be issued as long as the flight is cancelled more than 10 minutes prior to the scheduled departure. As the Company continues to believe that a portion of Customer flight credits issued after July 28, 2022, will not be redeemed, it continues to estimate and record breakage associated with such amounts. The amount of Customer flight credits represents approximately 7 percent and 9 percent of the total Air traffic liability balance as of JuneSeptember 30, 2023, and December 31, 2022, respectively.

The Company recognized revenue related to the marketing, advertising, and other travel-related benefits of the revenue associated with various loyalty partner agreements including, but not limited to, the Agreement with Chase Bank USA, N.A, within Other operating revenues. For the three months ended JuneSeptember 30, 2023 and 2022, the Company recognized $540$526 million and $522$521 million, respectively. For the sixnine months ended JuneSeptember 30, 2023 and 2022, the Company recognized $1.1$1.6 billion and $1.0$1.5 billion, respectively.
    

6.    NET INCOME PER SHARE
The following table sets forth the computation of basic and diluted net income per share (in millions except per share amounts). Basic net income per share is calculated by dividing net income by the weighted average of shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the three and sixnine months ended JuneSeptember 30, 2023 and 2022, an immaterial number of shares related to the Company's restricted stock units and stock warrants were excluded from the denominator because inclusion of such shares would be antidilutive.

7.    FAIR VALUE MEASUREMENTS

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of JuneSeptember 30, 2023, the Company held certain items that are required to be measured at fair value on a recurring basis. These included cash equivalents, short-term investments (primarily treasury bills), interest rate derivative contracts, fuel derivative contracts, and available-for-sale securities. The majority of the Company’s cash equivalents and short-term investments consist of instruments classified as Level 1. However, the Company has certificates of deposit, commercial paper, and time deposits that are classified as Level 2, due to the fact that the fair value for these instruments is determined utilizing observable inputs in non-active markets. Equity securities primarily consist of investments with readily determinable market values associated with the Company’s excess benefit plan.

The Company’s fuel and interest rate derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange. Fuel derivative instruments currently consist solely of option contracts, whereas interest rate derivatives consist solely of swap agreements. See Note 3 for further information on the Company’s derivative instruments and hedging activities. The fair values of swap contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized these swap contracts as Level 2. The Company’s Treasury Department, which reports to the Chief Financial Officer, determines the value of option contracts utilizing an option pricing model based on inputs that are either readily available in public markets, can be derived from information available in publicly quoted markets, or are provided by financial institutions that trade these contracts. The option pricing model used by the Company is an industry standard model for valuing options and is a similar model used by the broker/dealer community (i.e., the Company’s counterparties). The inputs to this option pricing model are the option

strike price, underlying price, risk free rate of interest, time to expiration, and volatility. Because certain inputs used to determine the fair value of option contracts are unobservable (principally implied volatility), the Company has categorized these option contracts as Level 3. Volatility information is obtained from external sources but is analyzed by the Company for reasonableness and compared to similar information received from other external sources. The fair value of option contracts considers both the intrinsic value and any remaining time value associated with those derivatives that have not yet settled. The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. To validate the reasonableness of the Company’s option pricing model, on a monthly basis, the Company compares its option valuations to third party valuations. If any significant differences were to be noted, they would be researched in order to determine the reason. However, historically, no significant differences have been noted. The Company has consistently applied these valuation techniques in all periods presented and believes it has obtained the most accurate information available for the types of derivative contracts it holds.

Included in Other available-for-sale securities are the Company’s investments associated with its deferred compensation plans, which consist of mutual funds that are publicly traded and for which market prices are readily available. These plans are non-qualified deferred compensation plans designed to hold contributions in excess of limits established by the Internal Revenue Code of 1986, as amended. The distribution timing and payment amounts under these plans are made based on the participant’s distribution election and plan balance. Assets related to the funded portions of the deferred compensation plans are held in a rabbi trust, and the Company remains liable to these participants for the unfunded portion of the plans. The Company records changes in the fair value of plan obligations and plan assets, which net to zero, within the Salaries, wages, and benefits line and Other (gains) losses line, respectively, of the unaudited Condensed Consolidated Statement of Comprehensive Income.Income (Loss).

The significant unobservable input used in the fair value measurement of the Company’s derivative option contracts is implied volatility. Holding other inputs constant, an increase (decrease) in implied volatility would have resulted in a higher (lower) fair value measurement, respectively, for the Company’s derivative option contracts.

The carrying amounts and estimated fair values of the Company’s short-term and long-term debt (including current maturities), as well as the applicable fair value hierarchy tier, as of JuneSeptember 30, 2023, are presented in the table below. The fair values of the Company’s publicly held long-term debt are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized these agreements as Level 2. All privately held debt agreements are categorized as Level 3. The Company has determined the estimated fair value of this debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes indicative pricing from counterparties and a discounted cash flow method to estimate the fair value of the Level 3 items.

(a) This amount includesAs of December 31, 2022, included customer reimbursement expenses due to the Company's December 2022 operational disruption and refund submissions that had yet to be processed. As of September 30, 2023, amounts primarily consist of normal current activity.
(b) Primarily consists of anticipated contract labor ratification bonuses and/or accruals. Also includes non-contract incentive pay. Included in Salaries, wages and benefits expense for the three and nine months ended September 30, 2023, is incremental expense of $96 million and $180 million, respectively, for changes in estimate related to the contract ratification bonus for the Company’s Flight Attendants as part of the tentative agreement reached in October 2023 with the Transport Workers Union 556 ("TWU 556"). The cumulative $180 million is included in the balance as of September 30, 2023. The Company began accruing for all of its open labor contracts on April 1, 2022, and this incremental $180 million expense extends the timeframe covered by the ratification bonus to the date the Flight Attendant contract became amendable on November 1, 2018, to compensate for missed wage increases over that time period.

9.    COMMITMENTS AND CONTINGENCIES

Contractual Obligations and Contingent Liabilities and Commitments

During 2022,On October 25, 2023, the Company entered into a supplemental agreementsagreement with The Boeing Company ("Boeing") relating to replaceits contractual order book for Boeing 737-7 and Boeing 737-8 aircraft. Based on the majority of its 2023Company's agreement with Boeing, 737 MAX 7 ("-7")capital commitments associated with firm orders with Boeing 737 MAX 8 ("-8") firm orders, among other adjustments to its near-term order book. During second quarteras of October 26, 2023, the Company exercised 30 -7 options for deliverywere: $133 million remaining in 2023, $2.1 billion in 2024, $1.7 billion in 2025, $1.8 billion in 2026, $2.6 billion in 2027, $2.9 billion in 2028, and converted 24 2024 -7 firm orders to -8 firm orders.

$5.3 billion thereafter.
The delivery schedule below reflects commitments, although the timing of future deliveries is uncertain as a result of delays in the manufacturing and certification process. For purposes of the delivery schedule below, the Company has included the remaining 46 of its 2022 contractual undelivered aircraft within its 2023 commitments, and has not made any further adjustments to this schedule based on current estimations. The Company continues to plan for approximately 70 -8 aircraft deliveries from Boeing and 26 -700 retirements in 2023. The Company retains significant flexibility to manage its fleet size, including opportunities to accelerate fleet modernization efforts if growth opportunities do not materialize. The Company is working to reflow its order book with Boeing.

Contingencies
Additional information regarding the Company's order book is included in the following table as of June 30, 2023:

The Boeing Company

202331 105 — 136 (c)

2030— 55 — 55 
2031— — — — 
192(a)270(b)102564

(a) The delivery timing for the -7 is dependent on the Federal Aviation Administration ("FAA") issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.
(b) The Company has flexibility to designate firm orders or options as -7s or -8s, upon written advance notification as stated in the contract.
(c) Includes 51 -8 deliveries received year-to-date through June 30, 2023. In addition, the Company has included the remaining 46 of its 2022 contractual undelivered aircraft (14 -7s and 32 -8s) within its 2023 commitments. The Company continues to plan for approximately 70 -8 aircraft deliveries in 2023. The 2023 order book detail is as follows:
The Boeing Company

Total
2022 Contractual Deliveries Remaining14 32 46 
2023 Contractual Deliveries17 73 90 
2023 Total31 105 136 

Boeing continues to experience delays in fulfilling its commitments with regards to delivery of MAX aircraft to the Company, as a result of both supply chain constraints as well as awaiting achievement of the FAA's certification of the -7, for which Southwest expects to be the launch customer. Therefore, for purposes of the Company’s aircraft order commitments with Boeing, the Company has assumed that any aircraft that were contractually due but remain undelivered as of December 31, 2022, have been rolled into the Company’s 2023 commitments, until such time as the Company and Boeing revise the aircraft order book. Based on the Company's existing agreement with Boeing, capital commitments associated with its firm orders as of June 30, 2023, were: $1.2 billion remaining in 2023 (and approximately $956 million, which relates to 46 MAX aircraft that were contractually committed for 2022 but were not received), $2.1 billion in 2024, $992 million in 2025, $1.4 billion in 2026, $1.1 billion in 2027, $1.3 billion in 2028, and $4.3 billion thereafter.

Contingencies
The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business and records a liability for such claims when it is probable that a loss will be incurred and the amount is reasonably estimable.

Based on the wide-scale operational disruption for the Company, which led to the cancelation of a significant number of flights between December 21 and December 29, 2022, the Company could be subject to fines and/or penalties resulting from investigations by the Department of Transportation or other government agencies. See Note 1. On October 27, 2023, the Department of Transportation notified the Company that it has determined the Company had failed to provide adequate customer service assistance, prompt flight status notifications, and proper and prompt refunds and that the assessment of a civil penalty is warranted. The Company could also face monetary damages or other costs resulting from litigation initiated by Customers and/or Shareholders. The Company is currently not able to estimate a range of possible loss for such items.

The Company is a defendant in class action litigation asserting it has not provided paid short-term military leave to certain employees, in violation of the federal Uniformed Services Employment and Reemployment Rights Act (“USERRA”). The United States District Court for the Northern District of California previously issued an order to effectively stay the action, pending an appeal from an order by the United States District Court for the Eastern District of Washington granting summary judgment in favor of an airline in a separate case involving substantially the same claims at issue in this action. On February 1, 2023, the Ninth Circuit reversed the district court’s grant of summary judgment and remanded the separate airline case to the District Court. The Ninth Circuit’s decision may adversely affect the Company’s defenses in the USERRA proceeding and may give rise to additional litigation in this or other areas. The Company is currently not able to estimate a range of possible loss with regards to the litigation to which it is a defendant.

10. FINANCING ACTIVITIES

On May 1, 2020, the Company completed the public offering of $2.3 billion aggregate principal amount of Convertible Senior Notes (the "Convertible Notes"). The Convertible Notes bear interest at a rate of 1.25% and will mature on May 1, 2025. Interest on the notes is payable semi-annually in arrears.

Holders may convert their Convertible Notes at their option at any time prior to the close of business on the business day immediately preceding February 1, 2025, in the event certain conditions are met, as stated in the offering documents. The Convertible Notes did not meet the criteria to be converted as of the date of the financial statements, and thus are classified as Long-term debt in the accompanying unaudited Condensed Consolidated Balance Sheet as of JuneSeptember 30, 2023. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company’s election. The Company intends to settle conversions by paying cash up to the principal amount of the Convertible Notes, with any excess conversion value settled in cash or shares of common stock. The initial conversion rate was 25.9909 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $38.48 per share of common stock). However, based on the Company's most recent cash dividends declared in MayAugust 2023, the bond conversion rate changed to 26.403826.5559 on June 20,September 5, 2023. The net carrying amount and principal amount of the Convertible Notes was $1.6 billion as of JuneSeptember 30, 2023 and December 31, 2022.

Financial Overview

In late December 2022, the Company experienced a wide-scale operational disruption as historically extreme winter weather across a significant portion of the United States impacted its operational plan and flight schedules. Subsequent to Winter Storm Elliott, the Company was challenged to realign flight crews, flight schedules, and aircraft for a period of several days during this peak demand travel period. This disruption and subsequent recovery efforts resulted in the cancellation of more than 16,700 flights during the period from December 21 through December 31, 2022. For first quarter 2023, these events also created a deceleration in bookings, primarily isolated to January and February 2023, as well as increased expenses primarily in the form of reimbursing Customers for costs incurred as a result of the flight cancellations. The financial impact of this disruption on the first quarter 2023 results was approximately $380 million on a pre-tax basis. There were no material impacts to operating revenues or expenses for the three months ended June 30,in 2023 following first quarter as a result of this disruption.

To boost operational resiliency in key areas across the Company and to mitigate the risk of a recurrence, the Company developed a three-part tactical action plan focused on improving winter operations, accelerating operational-related investments, and enhancing cross-team collaboration. The Company's action plan was released in March 2023.2023 and key winter operations steps were completed as of October 2023, as planned.

No assurance can be given that these efforts to boost operational resiliency in key areas across the Company will be successful in eliminating the risk of a recurrence. See "Risk Factors – The airline industry is made up of inherently complex systems, and is affected by many conditions that are beyond its control, which can impact the Company's business strategies and results of operations" included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

The Company recorded secondthird quarter and year-to-date results for 2023 and 2022 on an accounting principles generally accepted in the United States ("GAAP") and non-GAAP basis, as noted in the following tables. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

The Company's financial results for the three months ended JuneSeptember 30, 2023, on a GAAP and non-GAAP basis, decreased compared to the same prior year period primarily due to higher salaries, wages, and benefits expense and maintenance materials and repairs expense. Additionally,On a GAAP basis, the same prior year periodCompany's results for the three months ended September 30, 2023 also included approximately $300incremental expense of $96 million of additional breakage revenue driven by higher than normal flight credits issued during the pandemic that were set to expire unused, priorrelated to the contract ratification bonus for the Company’s Flight Attendants as part of the tentative agreement reached in October 2023, and for the three months ended September 30, 2022, also included a $76 million loss on extinguishment of debt due to the repurchase of the Company's July 2022 policy change to eliminate expiration dates on qualifying flight credits. The percentage of breakage revenue normalized to historical levels beginning in third quarter 2022.

The Company's financial results as shown abovefor the nine months ended September 30, 2023, on a GAAP and non-GAAP basis, for the six months ended June 30, 2023 included a negative financial impact of approximately $380 million on a pre-tax basis related to the December 2022 operational disruption. The same prior year period included additional breakage revenue driven by higher than normal flight credits issued during the pandemic that were set to expire unused, prior to the Company's July 2022 policy change to eliminate expiration dates on qualifying flight credits. The percentage of breakage revenue normalized to historical levels beginning in third quarter 2022. This additional revenue for the six months ended June 30, 2022 was partially offset by the effects of the Omicron variant of COVID-19, which reduced travel demand, particularly during January and February 2022.Additionally, Operating income for the first six months ended June 30, 2023 also decreased compared to the same prior year period primarily due to higher salaries, wages, and benefits expense partially offset by higher interest income.and maintenance materials and repairs expense.

The Company continues to expectAdjusting for the December 2022 operational disruption, which lowered capacity in fourth quarter 2022, the Company's fourth quarter 2023 capacity to increase in the range of 20would have been up roughly 15 percent, to 22 percent, year-over-year, and currentlyyear-over-year. The Company now expects first quarter 2024 capacity to increase in the range of 14approximately 10 percent to 1612 percent, year-over-year, of which nearly 90 percentall is from the carryover effect of capacity growth in 2023.2023, compared with its previous guidance to increase in the range of 14 percent to 16 percent, year-over-year. The Company also expects full year 2024 capacity to increase in the range of 6 percent to 8 percent, year-over-year.
(c) See Note Regarding Use of Non-GAAP Financial Measures for additional information on special items. In addition, information regarding special items and economic results is included in the accompanying table Reconciliation of Reported Amounts to Non-GAAP Measures (also referred to as "excluding special items").
(d) Based on the Company's existing fuel derivative contracts and market prices as of July 19,October 18, 2023, third quarter, fourth quarter and full year 2023 economic fuel costs per gallon are estimated to be in the range of $2.55$2.90 to $2.65, $2.50$3.00 and $2.85 to $2.60, and $2.70 to $2.80,$2.95, respectively. Economic fuel cost projections do not reflect the potential impact of special items because the Company cannot reliably predict or estimate the hedge accounting impact associated with the volatility of the energy markets, or the impact to its financial statements in future periods. Accordingly, the Company believes a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for projected results is not meaningful or available without unreasonable effort.

(e) Operating expenses per available seat mile, excluding fuel and oil expense, special items, and profitsharing ("CASM-X").
(f) Projections do not reflect the potential impact of fuel and oil expense, special items, and profitsharing because the Company cannot reliably predict or estimate those items or expenses or their impact to its financial statements in future periods, especially considering the significant volatility of the fuel and oil expense line item.

(g) 2023 CASM-X guidance excludes the impact of approximately $84 million related to labor accrual adjustments in second quarter 2023 that related primarily to prior periods. The Company has treated this amount, and the approximately $96 million labor accrual adjustment in third quarter 2023, as special items in its year-to-date 2023 Non-GAAP financial results. See the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for further information.
(h) Aircraft on property, end of period. The Company continues to plannow plans for approximately 7085 Boeing 737-8 ("-8") aircraft deliveries and 2641 Boeing 737-700 ("-700") aircraft retirements in 2023, endingand still plans to end the year with 814 aircraft. This is compared with its previous plan for approximately 70 -8 deliveries and 26 -700 retirements. The delivery schedule for the Boeing 737-7 ("-7") is dependent on the Federal Aviation Administration ("FAA") issuing required certifications and approvals to The Boeing Company ("Boeing") and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and Boeing may continue to experience supply chain challenges, so the Company therefore offers no assurances that current estimations and timelines are correct.

Thus far in fourth quarter 2023, overall demand for travel remains stable, including strong bookings to-date for the Company has experienced strongholiday travel periods. While leisure demand remains healthy, leisure trends appear to be returning to historically seasonal norms, and yields for July travel.business travel trends continue to be stable. Based on current booking and revenue trends, the Company anticipates a thirdrecord fourth quarter operating revenue driven by record fourth quarter passengers.

The Company expects fourth quarter 2023 RASM to decline in the range of 39 percent to 711 percent, year-over-year,year-over-year. This decline includes an approximate one and one-half point offset from the December 2022 operational disruption. The expected RASM decline is driven by challenging comparisons from the pent-up travel demand surgehigher-than-seasonally-normal ASM growth in 2022, and higher than seasonally-normal growth,fourth quarter 2023 as the

Company works to closecloses out the restoration of the network and normalizes the utilization of the fleet. Further, unit revenue pressure is also driven by higher-than-normal investment in development markets and schedules that are not ideally matched to current business travel trends. The Company is addressing these challenges in its 2024 network plan by adjusting capacity and further optimizing the network.

The Company expects thirdfourth quarter 2023 CASM-X to increase in the range of 3.5 percent to 6.5 percent, year-over-year, primarily due to continued inflationary cost pressures, including higher labor rates for all Employee workgroups and increased market wage rate accruals. Overall, nominal cost trends are expected to remain fairly consistent sequentially from second quarter 2023. The Company currently expects its full year 2023 CASM-X to decrease in the range of 116 percent to 219 percent, year-over-year.year-over-year, 15-points of which relates to elevated operating expenses and lower capacity levels in fourth quarter 2022 as a result of the December 2022 operational disruption. The guidance range is inclusive of higher labor rates and market wage rate accruals for all Employee workgroups, including wage rate increases associated with the recently announced tentative agreement with the Transport Workers of America Union Local 556 ("TWU 556").

In light of the -7 certification,new order book, the Company now plans for approximately 85 -8 deliveries from Boeing in 2023, and plans to accelerate additional -700 aircraft delivery delays extendedretirements into 2023, retiring a total of approximately 41 -700 aircraft in 2023. As a result, the Company continues to expect to end 2023 with 814 aircraft. For information about potential impacts resulting from prolonged delays related to the 737 MAX family of aircraft, see "Risk Factors – Operational Risks" included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

The Company entered into supplemental agreements in 2022revised order book with Boeing to increase aircraft orders and accelerate certain options with the goals of improving potential growth opportunities and frequencies to better align with the pre-pandemic operational route network, lowering operating costs, and further modernizing its fleet with less carbon-intensive aircraft. See Note 9 to the unaudited Condensed Consolidated Financial Statements for further information. The Company expects that more than half of the MAX aircraft in its firm order book will replace a significant amount of its 408 -700 aircraft over the next 10 to 15 yearscontinue to support the modernization of the Company's fleet, a key component of its environmental sustainability efforts. The Company's order book with Boeing as of June 30,October 26, 2023, consists of a total of 462573 MAX firm orders (192(302 -7 aircraft and 270271 -8 aircraft) for the years 2023 through 20302031 and 102207 MAX options (-7s or -8s) for the years 2025 through 2027. The Company is working to reflow its order book with Boeing in a way that provides orderly and measured growth in 2024 and beyond.2031.

The Company has published its flight schedule for sale through March 6,August 4, 2024. Although the Company's network is largely restored, it is not yet optimized. The Company is working to align its network, fleet plans,in the midst of planning for 2024 and staffing to better reflect the current business environment. While business revenues continue to recover, they are notis focused on operational excellence and driving out inefficiencies, increasing productivity, improving reliability, and returning margins back to pre-pandemic levels—therefore, the Company is revamping its 2024 flight schedules to reflect post-pandemic changes to Customer travel patterns. The Company estimates these meaningful network optimization efforts and the continued maturation of its development markets will contribute roughly $500 million in incremental year-over-year pre-tax profits in 2024, which the Company believes will support another year of margin expansion.historical levels.

As part of its commitment to corporate sustainability, the Company published its 2022 One Report describing the Company's sustainability strategies on May 3, 2023, which include the Company’s fuel conservation and emissions mitigation initiatives and other efforts to minimize greenhouse gas emissions and address other environmental matters such as energy and water conservation, waste minimization, and recycling. The Company also published its Diversity, Equity, and Inclusion ("DEI") Report on May 3, 2023. A companion piece to the One Report, the DEI Report takes a deeper dive into the Company's DEI goals and initiatives and highlights the Company's DEI plans for the future.

contained in the Southwest One Report, the DEI Report, and other voluntary disclosures regarding environmental, social, and governance (“ESG”) matters are responsive to various areas of investor interest, the Company believes that certain of these disclosures do not currently address matters that are material in the near term to the Company’s operations, strategy, financial condition, or financial results, although this view may change in the future based on new information that could materially alter the estimates, assumptions, or timelines used to create these disclosures. Given the estimates, assumptions, and timelines used to create the Southwest One Report, the DEI Report, and other voluntary disclosures, the materiality of these disclosures is inherently difficult to assess.

Comparison of three months ended JuneSeptember 30, 2023 and JuneSeptember 30, 2022

Operating Revenues

Total operating revenues for secondthird quarter 2023 increased by $309$305 million, or 4.64.9 percent, year-over-year, to achieve an all-time quarterlya third quarter Company record of $7.0$6.5 billion. Passenger revenues for third quarter 2023 increased by $299 million, or 5.3 percent, year-over-year. Other revenues for third quarter 2023 increased by $6 million, or 1.1 percent, year-over-year. These revenue increases were primarily due to a 12.5 percent increase in capacity and a 2.6 percent higher average fare, aided by increases in loyalty revenue and ancillary passenger revenues. The Company's Rapid Rewards® loyalty program also continues to be a point of strength, with record secondthird quarter new Member additions, a third quarter record level of Member engagement, and record secondthird quarter spend on the Company's co-branded Chase® Visa credit card. SecondThird quarter 2023 RASM was 16.5314.77 cents, a decrease of 8.36.8 percent, compared with secondthird quarter 2022. ThisAlso on a unit basis, third quarter Passenger revenues decreased 6.4 percent, year-over-year. These year-over-year RASM decrease was primarilyper unit decreases were largely driven by a decrease in yield of 4.0 percent coupled with a4.7 point decrease in Load factor of 3.7 points. The decrease in yield was primarily due to both the Company's and other domestic carriers' significant year-over-yearas capacity growth coming out of the pandemic to meetoutpaced demand and the Company's additional breakage revenue in second quarter 2022. The higher breakage in second quarter 2022 was driven by higher than normal flight credits issued during the pandemic that were set to expire unused, prior to the Company's July 2022 policy change to eliminate expiration dates on qualifying flight credits.The percentage of breakage revenue normalized to historical levels beginning in third quarter 2022.2023.

Holding other factors constant, the increase was primarily due to a 14.1 percent increase in capacity and an improvement in leisure and business demand in second quarter 2023. On a unit basis, Passenger revenues decreased 8.2 percent, year-over-year. The decrease was largely driven by a 4.0 percent decrease in Passenger revenue yield as a result of the significant year-over-year capacity increases by the Company and other domestic carriers, as well as higher breakage amounts recorded in second quarter 2022, prior to the Company's policy change regarding the expiration of flight credits.

Other revenues for second quarter 2023 increased by $19 million, or 3.4 percent, compared with second quarter 2022. On a dollar basis, the increase was primarily due to additional marketing revenue from Chase Bank USA, N.A ("Chase"), driven by improved retail spend on the Company's co-brand credit card.

Operating Expenses

Operating expenses for secondthird quarter 2023 increased by $672$583 million, or 12.110.0 percent, compared with secondthird quarter 2022, while capacity increased 14.112.5 percent over the same prior year period. The vast majority of the dollar increase was due to higher Salaries, wages, and benefits expense, partially offset by a year-over-year decrease in Fuel and oil expense. Historically, except for changes in the price of fuel, changes in Operating expenses for airlines have been largely driven by changes in capacity, or ASMs. The following table presents the Company's Operating expenses per ASM for the secondthird quarter of 2023 and 2022, followed by explanations of these changes on a dollar basis. Unless otherwise specified, changes on a per ASM basis were driven by changes in capacity, which increased with the improvement of travel demand, causingand caused the Company's fixed costs to be spread over significantly more ASMs.

Operating expenses per ASM for secondthird quarter 2023 decreased by 1.72.2 percent, compared with secondthird quarter 2022, primarily due to a significant decrease in the Company's fuel cost per gallon. Operating expenses per ASM for secondthird quarter 2023, excluding Fuel and oil expense, profitsharing, and special items (a non-GAAP financial measure), increased 7.54.4 percent, compared with secondthird quarter 2022, primarily due to general inflationary cost pressures, in particular higher labor rates for all Employee workgroups, including market wage rate accruals forassociated with open collective bargainingcontract labor agreements, as well as the timing of planned maintenance expensesexpenses.

Salaries, wages, and benefits expense for secondthird quarter 2023 increased by $566$406 million, or 25.517.5 percent, compared with secondthird quarter 2022. On a per ASM basis, secondthird quarter 2023 Salaries, wages, and benefits expense increased 10.14.2 percent, compared with secondthird quarter 2022. On a dollar basis, approximately 5060 percent of the increase was due to step/pay rate increases for certain workgroups, including market wage rate accruals for open collective bargaining agreements (inclusive of $96 million on a GAAP basis in additional compensation in third quarter 2023 for past services, as part of the contract ratification bonus negotiated as part of the tentative agreement reached with TWU 556), and approximately 2520 percent of the increase was driven by an increase in capacity and/or number of trips flown. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP measures.

Fuel and oil expense for secondthird quarter 2023 decreased by $233$186 million, or 14.210.6 percent, compared with secondthird quarter 2022. On a per ASM basis, secondthird quarter 2023 Fuel and oil expense decreased 24.920.4 percent. On a dollar basis, the decrease was primarily attributable to a decrease in the Company's average economic jet fuel cost per gallon, partially offset by an increase in fuel gallons consumed. The Company's secondthird quarter 2023 average economic jet fuel price of $2.60$2.78 per gallon is net of approximately $45$94 million in cash settlements from hedging activities. On a per ASM basis, the majority of the change was also due to lower average economic jet fuel prices. The following table provides more information on the Company's economic fuel cost per gallon, including the impact of fuel hedging premium expense and fuel derivative contract settlements:

The Company's secondthird quarter 2023 available seat miles per gallon ("fuel efficiency") increased 3.33.9 percent, year-over-year, due to the Company operating more of its most fuel-efficient MAX aircraft within its fleet. The continued deliveries of MAX aircraft are expected to remain critical to the Company's efforts to modernize its fleet, reduce carbon emissions intensity, and achieve its near-term environmental sustainability goals.

(b) Based on the Company's existing fuel derivative contracts and market prices as of July 19,October 18, 2023, third quarter, fourth quarter and full year 2023 economic fuel costs per gallon are estimated to be in the range of $2.55$2.90 to $2.65, $2.50$3.00 and $2.85 to $2.60, and $2.70 to $2.80,$2.95, respectively. Economic fuel cost projections do not reflect the potential impact of special items because the Company cannot reliably predict or estimate the hedge accounting impact associated with the volatility of the energy markets, or the impact to its financial statements in future periods. Accordingly, the Company believes a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for projected results is not meaningful or available without unreasonable effort.

(b) The Company's maximum fuel hedged percentage is calculated using the maximum number of gallons that are covered by derivative contracts divided by the Company's estimate of total fuel gallons to be consumed for each respective period. The Company's maximum number of gallons that are covered by derivative contracts may be at different strike prices and at strike prices materially higher than the current market prices. The volume of gallons covered by derivative contracts that ultimately get exercised in any given period may vary significantly from the volumes used to calculate the Company's maximum fuel hedged percentages, as market prices and the Company's fuel consumption fluctuate.

Maintenance materials and repairs expense for secondthird quarter 2023 increased by $61$122 million, or 29.059.8 percent, compared with secondthird quarter 2022. On a per ASM basis, Maintenance materials and repairs expense increased 14.342.3 percent, compared with secondthird quarter 2022. On a dollar and per ASM basis, the increase was primarily due to an increase in engine shop visits and various other engine repairs. The majority of these increasesThese engine expenses are associated with both the Company’s -700 fleet, due to an increase in the number of engines inducted for planned performance shop restoration visits as a result of their utilization, and planned shop visits for the Company's Boeing 737-800 ("-800") fleet, as -800 aircraft emerge from their maintenance “honeymoon” period, during which the aircraftengines have required significantly lower levels of maintenance while in the early phases of their useful lives.

Landing fees and airport rentals expense for secondthird quarter 2023 increased by $71$62 million, or 18.315.7 percent, compared with secondthird quarter 2022. On a per ASM basis, Landing fees and airport rentals expense increased 3.83.0 percent, compared with secondthird quarter 2022. On a dollar basis, approximately 50 percent of the increase was attributable to an increase in airport rental expense throughout the network driven by higher rates and approximately 40 percent of the increase was attributable to higher landing fees, primarily driven both by the increase in trips flown and higher rates charged by airports. The remainder of the increase was largely due to higher rental expense throughout the network, associated with both higher rates and additional space leased at airports.

Depreciation and amortization expense for secondthird quarter 2023 increased by $42$40 million, or 12.911.9 percent, compared with secondthird quarter 2022. On a per ASM basis, Depreciation and amortization expense decreased by 1.1 percent,remained flat, compared with secondthird quarter 2022. On a dollar basis, approximately 70 percent of the increase was primarily due to the acquisition of 107102 -8 aircraft since second quarter 2022, and the remaining increase was primarily due to decreasing the airframe salvage value for the entire -700 fleet, which was a change in estimate made in third quarter 2022. This change in estimate was not material to second quarter 2023, nor is it expected to have a material impact on future periods.

Interest expense for secondthird quarter 2023 decreased by $28$23 million, or 30.126.7 percent, compared with secondthird quarter 2022, primarily due to various debt repurchases since secondthird quarter 2022. See Note 10 to the unaudited Condensed Consolidated Financial Statements for further information.

Capitalized interest for secondthird quarter 2023 decreased by $6$7 million, or 54.563.6 percent, compared with secondthird quarter 2022, primarily due to a significant amount of assets being placed into service since secondthird quarter 2022, most notably the delivery of 2118 -8 aircraft in secondthird quarter 2023.

Interest income for secondthird quarter 2023 increased by $116$86 million, compared with secondthird quarter 2022, primarily due to higher interest rates earned on the Company's cash and short-term investments.

Loss on extinguishment of debt for secondthird quarter 2023 decreased by $43$76 million compared with secondthird quarter 2022, primarily due to the partial extinguishment of the Company's Convertible Notes in secondthird quarter 2022, compared to none in secondthird quarter 2023.

Income Taxes

The Company's effective tax rate was 22.918.5 percent in secondthird quarter 2023, compared with 26.621.6 percent in secondthird quarter 2022. The year-over-year decline in the tax rate was primarily due to the absence of losses on convertible debt repurchases, which were largely disallowed as a tax deduction in 2022. The Company currently estimates its annual 2023 effective tax rate to be in the range ofapproximately 23 percent to 24 percent.

Loss on extinguishment of debt for the first sixnine months of 2023 decreased by $116$192 million, compared with the first sixnine months of 2022, primarily due to the partial extinguishment of the Company's Convertible Notes in the first sixnine months of 2022, compared with none in the first sixnine months of 2023.

The following table displays the components of Other (gains) losses, net, for the sixnine months ended JuneSeptember 30, 2023 and 2022:

Income Taxes

The Company's effective tax rate was approximately 23.222.0 percent for the first sixnine months of 2023, compared with 26.925.1 percent for the first sixnine months of 2022. The year-over-year decline in the tax rate was primarily due to the absence of losses on convertible debt repurchases, which were largely disallowed as a tax deduction in 2022.

(a) Represents changes in estimate related to the contract ratification bonus for the Company’s Flight Attendants as part of the tentative agreement reached in October 2023 with TWU 556. The Company began accruing for all of its open labor contracts on April 1, 2022, and this incremental $180 million expense extends the timeframe covered by the ratification bonus to the date the Flight Attendant contract became amendable on November 1, 2018, to compensate for missed wage increases over that time period. The Company’s consolidated financial statements for the three and nine months ended September 30, 2023 include market rate wage accrual for all workgroups with open collective bargaining agreements. The Company had not previously included an approximate $84 million adjustment associated with ongoing labor contract negotiations during second quarter 2023 as a special item, but has now included such amount in its calculation of Non-GAAP financial measures for the year-to-date period ended September 30, 2023. The Company is therefore providing adjusted reconciliation schedules for second quarter 2023 as supplemental information below. See the Note Regarding Use of Non-GAAP Financial Measures for further information.
(b) See Note 3 to the unaudited Condensed Consolidated Financial Statements for further information.

Note Regarding Use of Non-GAAP Financial Measures

The Company's unaudited Condensed Consolidated Financial Statements are prepared in accordance with GAAP. These GAAP financial statements may include (i) unrealized noncash adjustments and reclassifications, which can be significant, as a result of accounting requirements and elections made under accounting pronouncements relating to derivative instruments and hedging and (ii) other charges and benefits the Company believes are unusual and/or infrequent in nature and thus may make comparisons to its prior or future performance difficult.

As a result, the Company also provides financial information in this filing that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides supplemental non-GAAP financial information (also referred to as "excluding special items"), including results that it refers to as "economic," which the Company's management utilizes to evaluate its ongoing financial performance and the Company believes provides additional insight to investors as supplemental information to its GAAP results. The non-GAAP measures provided that relate to the Company’s performance on an economic fuel cost basis include Fuel and oil expense, non-GAAP; Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Fuel and oil expense; Operating expenses, non-GAAP excluding Fuel and oil expense and profitsharing; Operating income, non-GAAP; Other (gains) losses, net, non-GAAP; Income before income taxes, non-GAAP; Provision for income taxes, net, non-GAAP; Net income, non-GAAP; Net income per share, diluted, non-GAAP; and Operating expenses per ASM, non-GAAP, excluding Fuel and oil expense and profitsharing (cents). The Company's economic Fuel and oil expense results differ from GAAP results in that they only include the actual cash settlements from fuel hedge contracts - all reflected within Fuel and oil expense in the period of settlement. Thus, Fuel and oil expense on an economic basis has historically been utilized by the Company, as well as some of the other airlines that utilize fuel hedging, as it reflects the Company’s actual net cash outlays for fuel during the applicable period, inclusive of settled fuel derivative contracts. Any net premium costs paid related to option contracts that are designated as hedges are reflected as a component of Fuel and oil expense, for both GAAP and non-GAAP (including economic) purposes in the period of contract settlement. The Company believes these economic results provide further insight into the impact of the Company's fuel hedges on its operating performance and liquidity since they exclude the unrealized, noncash adjustments and reclassifications that are recorded in GAAP results in accordance with accounting guidance relating to derivative instruments, and they reflect all cash settlements related to fuel derivative contracts within Fuel and oil expense. This enables the Company's management, as well as investors and analysts, to consistently assess the Company's operating performance on a year-over-year or quarter-over-quarter basis after considering all efforts in place to manage fuel expense. However, because these measures are not determined in accordance with GAAP, such measures are susceptible to varying calculations, and not all companies calculate the measures in the same manner. As a result, the aforementioned measures, as presented, may not be directly comparable to similarly titled measures presented by other companies.

Further information on (i) the Company's fuel hedging program, (ii) the requirements of accounting for derivative instruments, and (iii) the causes of hedge ineffectiveness and/or mark-to-market gains or losses from derivative instruments is included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and Note 3 to the unaudited Condensed Consolidated Financial Statements.

The Company’s GAAP results in the applicable periods may include other charges or benefits that are also deemed "special items," that the Company believes make its results difficult to compare to prior periods, anticipated future periods, or industry trends. Financial measures identified as non-GAAP (or as excluding special items) have been adjusted to exclude special items. For the periods presented, in addition to the items discussed above, special items include:

1.Noncash impairment charges, primarily associated with adjustments to the salvage values for previously retired airframes;
2.Unrealized mark-to-market adjustment associated with certain available for sale securities;
3.Losses associated with the partial extinguishment of the Company's Convertible Notes and early prepayment of debt. These losses are also now presented as a separate line item in the unaudited Condensed

Table of Contents
Consolidated Statement of Comprehensive Income, rather than its prior presentation where it was included as a component of Other (gains) losses, net. Such losses are incurred as a result of opportunistic decisions made by the Company to

prepay portions of its debt, most of which was incurred during the pandemic in order to provide liquidity during the prolonged downturn in air travel; and
4.A charge associated with a tentative litigation settlement regarding certain California state meal-and-rest-break regulations for flight attendants.attendants; and
5.Incremental expense associated with ongoing labor contract negotiations with TWU 556 which represents the Company’s Flight Attendants. The change in estimate recognized in the second and third quarters of 2023 relates to additional compensation for services performed by Employees outside of those applicable fiscal periods.

Because management believes special items can distort the trends associated with the Company’s ongoing performance as an airline, the Company believes that evaluation of its financial performance can be enhanced by a supplemental presentation of results that exclude the impact of special items in order to enhance consistency and comparativeness with results in prior periods that do not include such items and as a basis for evaluating operating results in future periods. The following measures are often provided, excluding special items, and utilized by the Company’s management, analysts, and investors to enhance comparability of year-over-year results, as well as to industry trends: Fuel and oil expense, non-GAAP; Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Fuel and oil expense; Operating expenses, non-GAAP excluding Fuel and oil expense and profitsharing; Operating income, non-GAAP; Other (gains) losses, net, non-GAAP; Income before income taxes, non-GAAP; Provision for income taxes, net, non-GAAP; Net income, non-GAAP; Net income per share, diluted, non-GAAP; and Operating expenses per ASM, non-GAAP, excluding Fuel and oil expense and profitsharing (cents).


Liquidity and Capital Resources

Net cash provided by operating activities was $1.4 billion$616 million for the three months ended JuneSeptember 30, 2023, compared with $1.9 billion$234 million provided by operating activities in the same prior year period. Net cash provided by operating activities was $2.1$2.7 billion for the sixnine months ended JuneSeptember 30, 2023, compared with $3.0$3.2 billion provided by operating activities in the same prior year period. Operating cash inflows are historically primarily derived from providing air transportation to Customers. The vast majority of tickets are purchased prior to the day on which travel is provided and, in some cases, several months before the anticipated travel date. Operating cash outflows are related to the recurring expenses of airline operations. The operating cash flows for the sixnine months ended JuneSeptember 30, 2023, were largely impacted by the Company's net income (as adjusted for noncash items), an $809a $750 million increase in Air traffic liability driven by higher ticket sales related to an increase in travel demand, an increase of $140 million in excise tax liabilities due to an increase in sales related to an increase in travel demand, partially offset by a $243$245 million decrease related to the purchase of fuel derivative instruments, which is included within Other, net operating cash flows in the accompanying unaudited Condensed Consolidated Statement of Cash Flows, and a $215 million decrease due to the payment of Customer reimbursement expenses in first quarter 2023 related to the December 2022 operational disruption. The operating cash flows for the sixnine months ended JuneSeptember 30, 2022, were largely impacted by the Company's net income (as adjusted for noncash items), a $793$700 million increase in Air traffic liability driven by higher ticket sales related to an increase in travel demand, a $284 million increase in cash collateral received from derivative counterparties due to an increase in the fuel hedge portfolio, driven by increases in the forward curve market prices for energy commodities year-to-date, and a $472 million cash tax refund from the Internal Revenue Service associated with the 2020 tax year. Net cash provided by operating activities is primarily used to finance capital expenditures, repay debt, pay dividends, and provide working capital.

Net cash used in investing activities totaled $627$64 million during the three months ended JuneSeptember 30, 2023, compared with $1.6$1.1 billion used in investing activities in the same prior year period. Net cash used in investing activities for the sixnine months ended JuneSeptember 30, 2023, was $2.2$2.3 billion, compared with $1.7$2.8 billion used in investing activities in the same prior year period.

During the sixnine months ended JuneSeptember 30, 2022, the Company repaid $555 million$2.5 billion in debt and finance lease obligations, including a $1.3 billion prepayment for all of its outstanding 4.75% Notes due 2023 and the early extinguishment of $302$486 million in principal of its Convertible Notes for a cash payment of $409payments totaling $648 million.

The Company is a "well-known seasoned issuer" and currently has an effective shelf registration statement registering an indeterminate amount of debt and equity securities for future sales. The Company currently intends to use the proceeds from any future securities sales off this shelf registration statement for general corporate purposes.

The Company has access to $1.0 billion under its amended and restated revolving credit facility (the "Amended A&R Credit Agreement"). In August 2023, this facility was amended to, among other things, (i) extend the expiration date to August 2028, (ii) release all aircraft and other assets constituting collateral securing loans under the facility, (iii) eliminate the minimum liquidity covenant, (iv) add a Coverage Ratio financial covenant, and (v) amend the covenant requiring that a pool of lien-free specified aircraft and related assets have a minimum aggregate appraised value. There were no amounts outstanding under the Amended A&R Credit Agreement as of JuneSeptember 30, 2023. See Note 10 to the unaudited Condensed Consolidated Financial Statements for further information.

Although not the case at JuneSeptember 30, 2023, due to the Company's significant financing activities throughout the early stages of the pandemic, the Company has historically carried a working capital deficit, in which its current liabilities exceed its current assets. This is common within the airline industry and is primarily due to the nature of the Air traffic liability account, which is related to advance ticket sales, unused flight credits available to Customers, and loyalty deferred revenue, which are performance obligations for future Customer flights, do not require future settlement in cash, and are mostly nonrefundable. See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information.

The Company believes it has various options available to meet its capital and operating commitments, including unrestricted cash and short-term investments of $12.2$11.7 billion as of JuneSeptember 30, 2023, and anticipated future internally generated funds from operations. The Company continues to have a large base of unencumbered assets with a net book value of more than $14.0$14.5 billion, including aircraft valued in excess of $11.5$12.0 billion and more than $2.5 billion in non-aircraft assets such as spare engines, ground equipment, and real estate. In addition, the Company continues to maintain investment-grade credit ratings by all three major credit agencies (Moody's, S&P Global, and Fitch).

Contractual Obligations

On October 25, 2023, the Company entered into a supplemental agreement with Boeing relating to its contractual order book for -7 and -8 aircraft. This agreement, which extends the order book to 2031, provides flexibility in support of the Company's growth plans and fleet modernization.

Table of Contents

The Company now plans for approximately 85 -8 aircraft deliveries from Boeing and 41 -700 retirements in 2023. The delivery schedule below reflects contractual commitments, although the timing of future deliveries could be affected by any potential or prolonged delays in the manufacturing process or with the -7 certification. The Company retains significant flexibility to manage its fleet size, including opportunities to accelerate fleet modernization efforts if growth opportunities do not materialize.

As of June 30,October 26, 2023, the Company had firm deliveries and options for -7 and -8 aircraft as follows:
The Boeing Company

(a) The delivery timing for the -7 is dependent on the FAA issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.
(b) The Company has flexibility to designate firm orders or options as -7s or -8s, upon written advance notification as stated in the contract.
(c) Includes 69 -8 deliveries received year-to-date through September 30, 2023. The Company now plans for approximately 85 -8 aircraft deliveries in 2023.

Based on the Company's total firm and option order bookrevised agreement with Boeing, was 564 aircraft. See Note 9 to the unaudited Condensed Consolidated Financial Statements for further information.capital commitments associated with its firm orders as of October 26, 2023, were: $133 million remaining in 2023, $2.1 billion in 2024, $1.7 billion in 2025, $1.8 billion in 2026, $2.6 billion in 2027, $2.9 billion in 2028, and $5.3 billion thereafter.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Hedging

As discussed in Note 3 to the unaudited Condensed Consolidated Financial Statements, the Company endeavors to acquire jet fuel at the lowest possible price and to reduce volatility in operating expenses through its fuel hedging program with the use of financial derivative instruments. As of JuneSeptember 30, 2023, the estimated fair value of outstanding contracts was a net asset of $316$487 million.

The Company's credit exposure related to fuel derivative instruments is represented by the fair value of contracts that are in an asset position to the Company. At such times, these outstanding instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the agreements. As of JuneSeptember 30, 2023, the Company had eight counterparties for which the derivatives held were a net asset. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings, limits its exposure with respect to each counterparty, and monitors the market position of the fuel hedging program and its relative market position
49

Table of Contents
with each counterparty. However, if one or more of these counterparties were in a net liability position to the Company and were unable to meet their obligations, any open derivative contracts with the counterparty could be subject to early termination, which could result in substantial losses for the Company. As of JuneSeptember 30, 2023, the Company had agreements with all of its active counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount based on the counterparty's credit rating. The Company also had agreements with counterparties in which cash deposits and/or letters of credit are required to be posted as collateral whenever the net fair value of derivatives associated with those counterparties exceeds specific thresholds. Refer to the counterparty credit risk and collateral table provided in Note 3 to the unaudited Condensed Consolidated Financial Statements for the fair values of fuel derivatives, amounts held as collateral, and applicable collateral posting threshold amounts as of JuneSeptember 30, 2023, at which such postings are triggered.
 
52

Table of Contents
As of JuneSeptember 30, 2023, $60$100 million in cash collateral deposits were held by the Company from counterparties based on the Company's outstanding fuel derivative instrument portfolio. Due to the types of derivatives held as of JuneSeptember 30, 2023, the Company does not have cash collateral exposure. See Note 3 to the unaudited Condensed Consolidated Financial Statements.

The Company is also subject to the risk that the fuel derivatives it uses to hedge against fuel price volatility do not provide adequate protection. The Company has found that financial derivative instruments in commodities, such as WTI crude oil, Brent crude oil, and refined products, such as heating oil and unleaded gasoline, can be useful in decreasing its exposure to jet fuel price volatility.

Financial Market Risk

The Company currently has agreements with organizations that process credit card transactions arising from purchases of air travel tickets by its Customers utilizing American Express, Discover, and MasterCard/VISA. Credit card processors have financial risk associated with tickets purchased for travel because the processor generally forwards the cash related to the purchase to the Company soon after the purchase is completed, but the air travel generally occurs after that time; therefore, the processor will have liability if the Company does not ultimately provide the air travel. Under these processing agreements, and based on specified conditions, increasing amounts of cash reserves could be required to be posted with the counterparty. There was no cash reserved for this purpose as of JuneSeptember 30, 2023.

A majority of the Company’s sales transactions are processed by Chase Paymentech. Should chargebacks processed by Chase Paymentech reach a certain level, proceeds from advance ticket sales could be held back and used to establish a reserve account to cover such chargebacks and any other disputed charges that might occur. Additionally, cash reserves are required to be established if the Company’s credit rating falls to specified levels below investment grade. Cash reserve requirements are based on the Company’s public debt rating and a corresponding percentage of the Company’s Air traffic liability. As of JuneSeptember 30, 2023, no holdbacks were in place.

See Item 7A "Quantitative and Qualitative Disclosures About Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, 2022, for further information about market risk, and Note 3 to the unaudited Condensed Consolidated Financial Statements in this Form 10-Q for further information about the Company's fuel derivative instruments.

PART II. OTHER INFORMATION

Item 1.     Legal Proceedings

On June 30, 2015, the U.S. Department of Justice ("DOJ") issued a Civil Investigative Demand ("CID") to the Company. The CID sought information and documents about the Company’s capacity from January 2010 to the date of the CID, including public statements and communications with third parties about capacity. In June 2015, the Company also received a letter from the Connecticut Attorney General requesting information about capacity. The Company is cooperating fully with the DOJ CID and the state inquiry.

Further, on July 1, 2015, a complaint was filed in the United States District Court for the Southern District of New York on behalf of putative classes of consumers alleging collusion among the Company, American Airlines, Delta Air Lines, and United Airlines to limit capacity and maintain higher fares in violation of Section 1 of the Sherman Act. Since then, a number of similar class action complaints were filed in the United States District Courts for the Central District of California, the Northern District of California, the District of Columbia, the Middle District of Florida, the Southern District of Florida, the Northern District of Georgia, the Northern District of Illinois, the Southern District of Indiana, the Eastern District of Louisiana, the District of Minnesota, the District of New Jersey, the Eastern District of New York, the Southern District of New York, the Middle District of North Carolina, the District of Oklahoma, the Eastern District of Pennsylvania, the Northern District of Texas, the District of Vermont, and the Eastern District of Wisconsin. On October 13, 2015, the Judicial Panel on Multi-District Litigation centralized the cases to the United States District Court in the District of Columbia. On March 25, 2016, the plaintiffs filed a Consolidated Amended Complaint in the consolidated cases alleging that the defendants conspired to restrict capacity from 2009 to present. The plaintiffs seek to bring their claims on behalf of a class of persons who purchased tickets for domestic airline travel on the defendants' airlines from July 1, 2011 to present. They seek treble damages, injunctive relief, and attorneys' fees and expenses. On May 11, 2016, the defendants moved to dismiss the Consolidated Amended Complaint, which the Court denied on October 28, 2016. On December 20, 2017, the Company reached an agreement to settle these cases with a proposed class of all persons who purchased domestic airline transportation services from July 1, 2011, to the date of the settlement. The Company agreed to pay $15 million and to provide certain cooperation with the plaintiffs as set forth in the settlement agreement. After notice was provided to the proposed settlement class and the Court held a fairness hearing the Court issued an order granting final approval of the settlement on May 9, 2019. On June 10, 2019, certain objectors filed notices of appeal to the United States Court of Appeals for the District of Columbia Circuit, which the Court dismissed on July 9, 2021, for lack of jurisdiction because the district court's order approving the settlements was not a final appealable order. The case is continuing as to the remaining defendants. The Company denies all allegations of wrongdoing.

On January 7, 2019, a complaint alleging a violation of the federal Uniformed Services Employment and Reemployment Rights Act (“USERRA”) and seeking a certification as a class action was filed against the Company in the United States District Court for the Northern District of California. The complaint alleges that the Company violates section 4316(b) of USERRA because it does not provide paid “short-term” military leave (i.e., a military leave of 14 days or fewer) but does provide paid jury duty leave, bereavement leave, and sick leave, which the plaintiff alleges are “comparable” forms of leave under USERRA and its implementing regulations. The complaint seeks declaratory and injunctive relief, damages, liquidated damages, interest, and attorneys’ fees, expert fees, and litigation costs. On February 3, 2021, the court granted the plaintiff’s motion for class certification and issued an order certifying a class comprised of current or former Employees who, during their employment with the Company at any time from October 10, 2004, through the date of judgment in this action, have taken short-term military leave and were subject to a collective bargaining agreement, except for Employees subject to the Transport Workers Union Local 550 agreement covering meteorologists. On January 11, 2022, the court granted the parties’ stipulated request to vacate the trial date as the Department of Defense had not yet produced the class members’ military pay and service records pursuant to the Company’s third-party subpoena. On August 18, 2022, the court entered an order that effectively stayed the action, except for attention to the third-party subpoena, until after the Ninth Circuit issued its opinion in the matter of Clarkson v. Alaska Airlines, Inc. and Horizon Industries, Inc., an appeal from an order by the United States District Court for the Eastern District of Washington granting summary judgment in defendants’ favor on substantially the same claims at issue in this action. The Ninth Circuit issued its order in Clarkson on February 1, 2023, reversing the district court’s grant of summary judgment and remanding the Clarkson case to the District Court with instructions to consider the “pay during leave” issue in the first instance.

On February 19, 2020, a complaint alleging violations of federal securities laws and seeking certification as a class action was filed against the Company and certain of its officers in the United States District Court for the Northern District of Texas in Dallas.Dallas (the "2020 Securities Litigation"). A lead plaintiff has been appointed in the case, and an amended complaint was filed on July 2, 2020. The amended complaint seeks damages on behalf of a putative class of persons who purchased the Company’s common stock between February 7, 2017, and January 29, 2020. The amended complaint asserts claims under Sections 10(b) and 20 of the Exchange Act and alleges that the Company made material misstatements to investors regarding the Company’s safety and maintenance practices and its compliance with federal regulations and requirements. The amended complaint generally seeks money damages, pre-judgment and post-judgment interest, and attorneys’ fees and other costs. On August 17, 2020, the Company and the individual defendants filed a motion to dismiss. On October 1, 2020, the lead plaintiff filed a response in opposition to the motion to dismiss.

On June 22, 2020, a derivative action for breach of fiduciary duty was filed in the United States District Court for the Northern District of Texas naming the members of the Company's Board of Directors as defendants and the Company as a nominal defendant (the "Derivative Action"). The plaintiff alleges unspecified damage to Company’s reputation, goodwill, and standing in the community, as well as damage from exposure to civil and regulatory liability and defense costs. According to the lawsuit, these damages arise from the Company’s alleged failure to comply with safety and record maintenance regulations and false statements in public filings regarding the Company’s safety practices. The plaintiff alleges the Board, in the absence of good faith, exhibited reckless disregard for its duties of oversight. On October 7, 2020, the Court entered an order staying and administratively closing the Derivative Action. The plaintiff inAction, pending the Derivative Action shall have the right to reopen the action following theDistrict Court's final resolution of the Company's motion to dismiss in the ongoing litigation2020 Securities Litigation brought under the federal securities laws or upon the occurrence of certain other conditions.

The Board and Company deny all allegations of wrongdoing made in the Derivative Action.

On August 26, 2021, a complaint alleging breach of contract and seeking certification as a class action was filed against the Company in the United States District Court for the Western District of Texas in Waco. The complaint alleges that the Company breached its Contract of Carriage and other alleged agreements in connection with its use of the allegedly defective MAX aircraft manufactured by The Boeing Company. The complaint seeks damages on behalf of putative classes of customers who provided valuable consideration, whether in money or other form (e.g., voucher, miles/points, etc.), in exchange for a ticket for air transportation with the Company, which transportation took place between August 29, 2017, and March 13, 2019. The complaint generally seeks money damages, declaratory relief, and attorneys’ fees and other costs. On October 27, 2021, the Company filed a multi-faceted motion challenging the complaint based upon lack of subject matter jurisdiction, the existence of a prior-filed complaint on appeal in the Fifth Circuit (the "Sherman Complaint"), improper venue, and failure to state a claim, and seeking to have the complaint's class contentions stricken. That motion was fully briefed by both parties and was argued to a United States Magistrate Judge on June 27, 2022. On July 5, 2022, the Magistrate Judge granted the motion in part and ordered the case stayed until the issuance of the Fifth Circuit's opinion in the Sherman Complaint. On November 28, 2022, the parties jointly notified the Court of the Fifth Circuit's decision regarding the Sherman Complaint. On March 23, 2023, the parties jointly notified the Court of the dismissal of the Sherman Complaint for lack of jurisdiction. The Company denies all allegations of wrongdoing, believes the plaintiffs' positions are without merit, and intends to vigorously defend itself in all respects.

Two complaints alleging violations of federal securities laws and seeking certification as a class action have been filed (on January 10, 2023 and March 13, 2023, respectively) against the Company and certain of its officers in the United States District Court for the Southern District of Texas in Houston.

The deadline in the first of these two cases to file a motion seeking appointment of lead plaintiff was March 13, 2023; four separate motions were filed, and three of the parties seeking appointment have continued to contest the issue. On July 17, 2023, the Court signed an order consolidating the two federal securities cases into the first-filed suit and also appointed plaintiff Michael Berry as lead plaintiff in the consolidated case, with his counsel of record to serve as lead counsel and liaison counsel. On September 15, 2023, the lead plaintiff filed an amended complaint that expanded the class period to include persons who purchased or otherwise acquired the Company's common stock between February 4, 2020, and March 14, 2023, while continuing to assert claims under Sections 10(b) and 20 of the Exchange Act based on alleged misstatements regarding the Company's internal technology and alleged vulnerability to large-scale flight disruptions. The Company denies all allegations of wrongdoing in the complaint, believes the plaintiffs' positions are without merit, and intends to vigorously defend itself in all respects.

Since about January 24, 2023, the Company’s senior officers and Board of Directors have received multiple derivative demand letters from legal counsel for purported Southwest shareholders demanding that the Board investigate claims, initiate legal action, and take remedial measures in connection with the service disruptions occurring in December 2022. Generally, the demand letters broadly assert that the Company’s directors and senior officers did not make sufficient investments in internal technology systems to prevent large-scale flight disruptions, did not exercise sufficient oversight over the Company’s operations, approved or received unwarranted compensation, caused the Company to make materially misleading public statements, and breached their fiduciary duties to the Company. Additionally, since January 27, 2023, the Company has received multiple letters from counsel for purported Southwest shareholders making statutory demands for the production of various books and records of the Company, purportedly in an effort to investigate possible derivative claims similar to those made the subject of the derivative demands discussed above. On June 13, 2023, a shareholder derivative suit was filed against certain of the Company’s current and former officers and directors in the 14th Judicial District Court of Dallas County, Texas, asserting claims for damages from alleged breach of fiduciary duty, waste of corporate assets, and unjust enrichment derivatively on the Company’s behalf against the individual defendants based on similar factual allegations as contained in the demand letters and in the federal class action complaints. On June 15, 2023, a second shareholder derivative suit was filed against certain of the Company’s current and former officers and directors in the United States District Court for the Northern District of Texas, asserting claims under Section 14(a) of the Exchange Act and for damages from alleged breach of fiduciary duty, indemnification, and unjust enrichment derivatively on the Company’s behalf against the individual defendants based on similar factual allegations as contained in the demand letters and in the federal class action complaints. The Company and its Board of Directors intend to address the derivative and books and records demands and the shareholder derivative suits in accordance with the applicable Texas statutes governing such demands and litigation. Pursuant to those statutes, a committee of independent and disinterested directors has been appointed to conduct an inquiry regarding the allegations in the derivative suits and derivative demand letters.

Based on the Company's wide-scale operational disruption, which led to the cancelation of a significant number of flights between December 21 and December 29, 2022, the Company could be subject to fines and/or penalties resulting from investigations by the Department of Transportation or other governmental agencies. On October 27, 2023, the Department of Transportation notified the Company that it has determined the Company failed to provide adequate customer service assistance, prompt flight status notifications, and proper and prompt refunds and that the assessment of a civil penalty is warranted. The Company intends to engage with the Department of Transportation to resolve the matter, which may involve payment of a civil penalty.

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business, including, but not limited to, examinations by the Internal Revenue Service.

The Company’s management does not expect that the outcome in any of its currently ongoing legal proceedings or the outcome of any proposed adjustments presented to date by the Internal Revenue Service, individually or collectively, will have a material adverse effect on the Company’s financial condition, results of operations, or cash flow. Nevertheless, an adverse outcome for any of these matters could be material.

Item 5. Other Information

None(a) On October 25, 2023, the Company entered into Supplemental Agreement No. 20 (the “Supplement”) to its Purchase Agreement No. 3729 with Boeing relating to the Company's purchase of -8 and -7 aircraft (collectively, “MAX aircraft”). Pursuant to the Supplement, the Company added 108 firm orders and 108 MAX aircraft options. The Supplement also amended the order book’s delivery schedule to better allocate deliveries from 2023 through 2031.

The Company continues to estimate its 2023 capital spending to be approximately $3.5 billion. This assumes approximately $2.3 billion in aircraft capital spending and $1.2 billion in non-aircraft capital spending, which includes tens of millions in operational investments related to the Company’s winter operations plan. The Company continues to estimate its total annual capital spending to be approximately $4 billion, on average, for the five years 2023 through 2027.

As a result of the Supplement, the Company has the following contractual firm deliveries and options for -7 and -8 aircraft:

(a) The delivery timing for the -7 is dependent on the FAA issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.
(b) The Company has flexibility to designate firm orders or options as -7s or -8s, upon written advance notification as stated in the contract.
(c) Includes 69 -8 deliveries received year-to-date through September 30, 2023. The Company now plans for approximately 85 -8 aircraft deliveries in 2023.

The foregoing summary of the Supplement does not purport to be complete and is qualified in its entirety by reference to the full text of the Supplement, a copy of which will be filed with the Company's Annual Report on Form 10-K for the fiscal year ending December 31, 2023.
