REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Delta Air Lines, Inc.

Results of Review of Interim Financial Statements

We have reviewed the accompanying consolidated balance sheet of Delta Air Lines, Inc. (the Company) as of JuneSeptember 30, 2023, the related condensed consolidated statements of operations and comprehensive income/(loss)income and consolidated statements of stockholders' equity for the three-month and six-monthnine-month periods ended JuneSeptember 30, 2023 and 2022, condensed consolidated statements of cash flows for the six-monthnine-month periods ended JuneSeptember 30, 2023 and 2022, and the related notes (collectively referred to as the "condensed consolidated interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2022, the related consolidated statements of operations, comprehensive income/(loss), cash flows, and stockholders' equity for the year then ended, and the related notes (not presented herein); and in our report dated February 10, 2023, we expressed an unqualified audit opinion on those Consolidated Financial Statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2022, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our consolidated subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Form 10-K for the year ended December 31, 2022.

Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair statement of results for the interim periods presented.

Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and sixnine months ended JuneSeptember 30, 2023 are not necessarily indicative of operating results for the entire year.

We reclassified certain prior period amounts to conform to the current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.

We recognized approximately $5.7$6.7 billion and $3.3$3.9 billion in passenger revenue during the sixnine months ended JuneSeptember 30, 2023 and 2022, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods.

As of JuneSeptember 30, 2023, all of our air traffic liability was recorded as a current liability. As of December 31, 2022, our air traffic liability was $8.3 billion, of which $100 million was included in other noncurrent liabilities on our Consolidated Balance Sheet ("balance sheet").

Loyalty Travel Awards

Our SkyMiles loyalty program allows customers to earn mileage credits ("miles") by flying on Delta, Delta Connection and other airlines that participate in the loyalty program. Loyalty travel awards revenue is related to the redemption of miles for air travel. Customers can also earn miles through participating companies, such as credit card companies, hotels, car rental agencies and ridesharing companies, who purchase miles from us. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. During the sixnine months ended JuneSeptember 30, 2023 and 2022, total cash sales from marketing agreements related to our loyalty program were $3.4$5.2 billion and $2.6$4.1 billion, respectively, which are allocated to travel and other performance obligations.

Notes to the Condensed Consolidated Financial Statements
Current Activity of the Loyalty Program. Miles are combined in one homogeneous pool and are not separately identifiable. Therefore, revenue is comprised of miles that were part of the loyalty program deferred revenue balance at the beginning of the period as well as miles that were issued during the period. The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned.

The table below presents the activity of the current and noncurrent loyalty program deferred revenue and includes miles earned through travel and miles sold to participating companies, which are primarily through marketing agreements.

Revenue by Geographic Region

Operating revenue for the airline segment is recognized in a specific geographic region based on the origin, flight path and destination of each flight segment. A significant portion of the refinery segment's revenues typically consists of fuel sales to support the airline, which is eliminated in the Condensed Consolidated Financial Statements. The remaining operating revenue for the refinery segment is included in the domestic region. Our passenger and operating revenue by geographic region is summarized in the following tables:

Cash Equivalents and Restricted Cash Equivalents. Cash equivalents generally consist of money market funds. Restricted cash equivalents generally consist of money market funds, time deposits, commercial paper and negotiable certificates of deposit, which primarily relate to certain self-insurance obligations and airport commitments. Restricted cash equivalents are recorded in prepaid expenses and other on our balance sheet. The fair value of these cash equivalents is based on a market approach using prices generated by market transactions involving identical or comparable assets.

Short-Term Investments. The fair values of our short-term investments are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted market prices, interest rates, benchmark curves, credit ratings of the security and other observable information.

As of JuneSeptember 30, 2023, the estimated fair value of our short-term investments was $3.42.2 billion. Of these investments, $3.1$2.1 billion are expected to mature in one year or less, with the remainder maturing by the first quarter of 2025.2026. Investments with maturities beyond one year when purchased are classified as short-term investments if they are expected to be available to support our short-term liquidity needs.

Long-Term Investments.Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. As of September 30, 2023 our equity investment in Wheels Up Experience Inc. ("Wheels Up") is classified as Level 3 in the fair value hierarchy. In prior periods, this investment was classified as Level 1. We determined the quoted price of its publicly-traded shares does not represent fair value after the closing of Wheels Up's $500 million credit facility on September 20, 2023. In addition to the quoted price, the valuation of our equity investment in Wheels Up considered certain unobservable inputs, including Wheels Up's financial projections, using both market and income approach valuation techniques. Fair value measurement using unobservable inputs is inherently uncertain, and a change in significant inputs could result in different fair values. See Note 4, "Investments," for further information on the transaction with Wheels Up and our other equity investments.

Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are primarily related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). Our fuel hedge portfolio may consist of a combination of options, swaps or futures contracts, most of which have a duration of less than three months. Option and swap contracts are valued under income approaches using option pricing models and discounted cash flow models, respectively, based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices. We recognized gainslosses of $12$140 million and $43$96 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income/(Loss)Income ("income statement") for the three and sixnine months ended JuneSeptember 30, 2023, respectively, compared to gains of $139 million and losses of $239 million and $478$339 million for the three and sixnine months ended JuneSeptember 30, 2022, respectively. The gainslosses recognized during the first sixnine months of 2023 were composed of $39$59 million of mark-to-market gains and $4$155 million of settlement gainslosses on contracts. Gains and losses on settled contracts are reflected within Monroe's operating results. See Note 9, "Segments," for further information on our Monroe refinery segment.

Notes to the Condensed Consolidated Financial Statements
NOTE 4. INVESTMENTS

We have developed strategic relationships with a number of airlines and airline services companies through joint ventures and other forms of cooperation and support, including equity investments. Our equity investments reinforce our commitment to these relationships and generally enhance our ability to offer input to the investee on strategic issues and direction, in some cases through representation on the board of directors.

Fair Value Investments. Changes in the valuation of investments accounted for at fair value are recorded in gain/(loss) on investments, net in our income statement within non-operating expense and are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in certain companies, particularly those without publicly-traded shares.

Equity Method Investments. We record our share of our equity method investees' financial results in our income statement as described in the table below.

Wheels Up. We, along with Certares Management LLC, Knighthead Capital Management LLC and Cox Enterprises, Inc. announced the closing on September 20, 2023 of an expanded strategic partnership with Wheels Up, which includes an agreement for a $500 million credit facility to Wheels Up. At closing, the credit facility was comprised of a $350 million term loan, of which we contributed $150 million, and a $100 million liquidity facility that we made available to Wheels Up in the event the company's liquidity falls below $100 million. The terms of the credit facility permit one or more new lenders to provide an aggregate incremental $50 million term loan after the closing date. In connection with the closing, the term loan investors received newly issued shares of Wheels Up's common stock representing 80% of Wheels Up's outstanding equity as of the closing of the credit facility on a fully diluted basis. Upon approval by Wheels Up's stockholders of an amendment to its certificate of incorporation, Wheels Up is expected to issue to the lenders additional new shares such that the lenders will own 95% of Wheels Up's outstanding equity as of the closing of the credit facility on a fully diluted basis.

The $150 million cash contribution was reflected as an investing outflow in our Condensed Consolidated Statement of Cash Flows and allocated on a relative fair value basis to a loan receivable within other noncurrent assets and an equity investment on our balance sheet. Combined with our previous ownership stake, this new investment provides us with a 39% equity stake in Wheels Up calculated based on Wheels Up's outstanding equity as of September 20, 2023. Our current percentage ownership does not reflect the anticipated dilutive effect from the additional shares to be issued to the lenders (including potentially to one or more new lenders under the term loan) upon approval by Wheels Up's stockholders and common stock grants expected to be made under Wheels Up's equity compensation plans. Furthermore, Delta's voting rights with respect to its Wheels Up equity stake are capped at 29.9%.

Notes to the Condensed Consolidated Financial Statements
As a result of the transaction, we concluded that Wheels Up is a variable interest entity ("VIE"). A VIE requires consolidation by the entity’s primary beneficiary. We determined that we are not the primary beneficiary after assessing the decision-making process for the significant activities of Wheels Up, concluding that Wheels Up's Board of Directors continues to possess the decision-making authority over the significant activities, and we do not control Wheels Up's Board. Based on this assessment, Wheels Up is not consolidated in our financial statements.

We continue to account for our equity interest under the fair value option, as originally elected as part of our initial acquisition of Wheels Up shares in 2020. We will also account for our loan receivable at fair value, as the fair value option is applied to all of an investor's financial interests in the same entity. None of the $100 million liquidity facility has been drawn as of September 30, 2023.

Availability Under Revolving Credit Facilities

As of JuneSeptember 30, 2023, we had approximately $2.8 billion undrawn and available under our revolving credit facilities. In addition, we had approximately $400 million outstanding letters of credit as of JuneSeptember 30, 2023 that did not affect the availability of our revolving credit facilities.

Early Settlement of Outstanding Notes

During the sixnine months ended JuneSeptember 30, 2023, we repurchased a principal amount of $1.1$1.4 billion of various secured and unsecured notes and a portion of the SkyMiles Term Loan on the open market and made early principal repayments of $585 million on various notes secured by aircraft. These payments resulted in a $50$63 million loss on extinguishment of debt recorded in non-operating expense in our income statement.

Aircraft Orders

During the June 2023 quarter, we agreed to acquire one A330-900 with delivery expected to occur in 2025. We also exercised purchase rights for 12 A220-300 with delivery expected to start in 2027.

Legal Contingencies

We are involved in various legal proceedings related to employment practices, environmental issues, commercial disputes, antitrust and other regulatory matters concerning our business. We record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount of loss can be reasonably estimated. Although the outcome of the legal proceedings in which we are involved cannot be predicted with certainty, we believe that the resolution of current matters will not have a material adverse effect on our Condensed Consolidated Financial Statements.

Employees Under Collective Bargaining Agreements

In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes numerous work rule changes and pay rate increases during the four-year term, including an initial pay rate increase of 18%. The agreement also includes a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million. Additionally, we recorded adjustments to other benefit-related items of approximately $130 million. These items are recorded within pilot agreement and related expenses in our income statement.

NOTE 9. SEGMENTS

Refinery Operations

Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and from jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. We use several counterparties to exchange the non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations. The gross fair value of the products exchanged under these agreements during the three and sixnine months ended JuneSeptember 30, 2023 was $618$519 million and $1.3$1.8 billion, respectively, compared to $1.0 billion$834 million and $1.8$2.6 billion for the three and sixnine months ended JuneSeptember 30, 2022, respectively.

Segment Reporting

Segment results are prepared based on our internal accounting methods described below, with reconciliations to consolidated amounts in accordance with GAAP. Our segments are not designed to measure operating income or loss directly related to the products and services included in each segment on a stand-alone basis.

Fair Value Obligations

The net fair value obligations presented in the table above are related to renewable fuel compliance costs and presented net of any related assets or fixed price purchase agreements. Their value is based on quoted market prices and other observable information and are therefore classified as Level 2 in the fair value hierarchy. AsOur obligation as of JuneSeptember 30, 2023 we had no net fair value obligation outstanding. Our obligation iswas calculated using the U.S. Environmental Protection Agency's ("EPA") Renewable Fuel Standard ("RFS") volume requirements, which were finalized in 2022 for the 2021 and 2022 obligations, and proposed in 2022 for 2023 obligations. In the March 2023 quarter, we settled a portion of our 2021 Renewable Identification Numbers ("RINs") obligation with the EPA. We expect to settle the remaining 2021 and our entire 2022 RINs obligation by the 2022 compliance deadline in the December 2023 quarter.

NOTE 10. EARNINGS/(LOSS)EARNINGS PER SHARE

We calculate basic earnings/(loss)earnings per share and diluted loss per share by dividing net income/(loss)income by the weighted average number of common shares outstanding, excluding restricted shares. We calculate diluted earnings per share by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based instruments, including stock options, restricted stock awards and warrants. Antidilutive common stock equivalents excluded from the diluted earnings per share calculation are not material.

Interest expense, net. Interest expense, net includes interest expense and interest income. This decreased compared to the prior year periodperiods as a result of increased interest income and reduced interest expense resulting from our debt reduction initiatives. Interest income increased as a result of higher interest rates and higher short-term investment balances throughout 2023. During 2022, we made payments of approximately $4.5 billion related to our debt and finance lease obligations which included approximately $2.3 billion of early repayment activity. Weand we have continued to pay down our debt during the sixnine months ended JuneSeptember 30, 2023 with $3.0$3.7 billion of payments on debt and finance lease obligations, including $1.1 billionof principal amounts for the early repurchase of various secured and unsecured notes and a portion of the SkyMiles Term Loan on the open market and early principal repayments of $585 million on various notes secured by aircraft. Approximately $1.4 billion of the early repurchases and repayments were scheduled to mature after 2023.obligations. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities.

Gain/(loss) on investments, net. Changes in the valuation of investments accounted for at fair value are recorded in gain/(loss) on investments, net and are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in certain companies, particularly those without publicly-traded shares. See Note 4 of the Notes to the Condensed Consolidated Financial Statements for additional information on our equity investments measured at fair value on a recurring basis.

Loss on extinguishment of debt. Loss on extinguishment of debt reflects the losses incurred in the early repayment of the notes mentioned above.certain loans and notes.

Pension and related (expense)/benefit. Pension and related (expense)/benefit reflects the net periodic (cost)/benefit of our pension and other postretirement and postemployment benefit plans. The unfavorable year-over-year change in pension and related (expense)/benefit results from lower expected return on plan assets during 2023. This is due to lower plan asset balances as of December 31, 2022, compared to December 31, 2021, primarily resulting from investment value declines in 2022 consistent with the broader stock market.financial markets.

Miscellaneous, net. Miscellaneous, net primarily includes foreign exchange gains/(losses), charitable contributions and our share of our equity method investments net results.


Income Taxes

We project our annual effective tax rate for 2023 will be between 22% and 25%24%. Our effective tax rate in 2023 may be impacted by mark-to-market adjustments on our equity investments. In certain interim periods, we may have adjustments to our net deferred tax assets as a result of changes in prior year estimates, changes in our mark-to-market equity investments and tax laws enacted during the period, which will impact the effective tax rate for that interim period.


Refinery Segment

The refinery operated by Monroe primarily produces gasoline, diesel and jet fuel. Monroe exchanges the non-jet fuel products the refinery produces with third parties for jet fuel consumed in our airline operations. The jet fuel produced and procured through exchanging gasoline and diesel fuel produced by the refinery providedprovides approximately 200,000 barrels per day, or approximately 75% of our consumption, for use in our airline operations.

The refinery generated lower operating income in the three and sixnine months ended JuneSeptember 30, 2023 compared to the three and sixnine months ended JuneSeptember 30, 2022, as a result of lower pricing.

Starting in mid-September 2023, the refinery is scheduled to complete a planned maintenance event ("turnaround")began the turnaround that is performed once every five years in accordance with the long-term maintenance plan of the facility to allow for safe completion of major repairs and upgrades. The turnaround is expected to take approximately two monthsconclude in mid-November 2023 and during thisuntil that time there will be no production at the refinery.

A refinery is subject to annual U.S. Environmental Protection Agency ("EPA") requirements to blend renewable fuels into the gasoline and on-road diesel fuel it produces. Alternatively, a refinery may purchase RINs from third parties in the secondary market. The Monroe refinery purchases the majority of its RINs in the secondary market. Observable RINs prices declined slightly since the beginning of 2023 through JuneSeptember 30, 2023 and Monroe incurred $105$80 million and $207$287 million in RINs compliance costs during the three and sixnine months ended JuneSeptember 30, 2023, respectively, compared to $223$140 million and $308$448 million in the three and sixnine months ended JuneSeptember 30, 2022.

As of JuneAt September 30, 2023, we had noa net fair value obligation outstanding.of $9 million related to RINs compliance costs. Our obligation isas of September 30, 2023 was calculated using the Renewable Fuel Standard ("RFS") volume requirements, which were finalized in 2022 for the 2021 and 2022 obligations, and proposed in 2022 for 2023 obligations. In the March 2023 quarter, we settled a portion of our 2021 RINs obligation with the EPA. We expect to settle the remaining 2021 and our entire 2022 RINs obligation by the 2022 compliance deadline in the December 2023 quarter.

For more information regarding the refinery's results, see Note 9 of the Notes to the Condensed Consolidated Financial Statements.

Item 2. MD&A - Financial Condition and Liquidity
Financial Condition and Liquidity

As of JuneSeptember 30, 2023, we had $8.8$7.8 billion in cash, cash equivalents, short-term investments and aggregate undrawn principal amount available under our revolving credit facilities ("liquidity"). We expect to meet our liquidity needs for the next twelve months with cash and cash equivalents, short-term investments and cash flows from operations. We expect to meet our long-term liquidity needs with cash flows from operations and financing arrangements.

Undrawn Lines of Credit. As of JuneSeptember 30, 2023, we had approximately $2.8 billion undrawn and available under our revolving credit facilities. In addition, we had approximately $400 million outstanding letters of credit as of JuneSeptember 30, 2023 that did not affect the availability of our revolving credit facilities.

Sources and Uses of Liquidity

Operating Activities

We generated cash flows from operations of $4.8$5.9 billion and $4.3$5.2 billion in the sixnine months ended JuneSeptember 30, 2023 and 2022, respectively. We expect to continue generating positive cash flows from operations during the remainder of 2023.

Our operating cash flow is impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date. When we receive a cash payment at the time of sale, we record the cash received on advance sales as deferred revenue in air traffic liability. The air traffic liability typically increases during the winter and spring months as advance ticket sales grow prior to the summer peak travel season and decreases during the summer and fall months. We continue to see a shift in customers purchasing flights further in advance compared to historical patterns, enhancing the positive cash flow from advance ticket sales.

Fuel. Fuel expense represented approximately 20%21% and 24%25% of our total operating expense for the sixnine months ended JuneSeptember 30, 2023 and 2022, respectively. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. Although the average fuel price per gallon decreased during the sixnine months ended JuneSeptember 30, 2023, fuel costs remain high compared to historical levels. We expect jet fuel prices to remain volatile throughout 2023.the remainder of 2023 and into 2024. Fuel consumption was also higher during the sixnine months ended JuneSeptember 30, 2023 compared to the prior year period due to the increase in capacity. We continue to expect that fuel consumption for the full year 2023 will continue to increase throughout 2023be higher compared to 2022, as we plananticipate capacity for ourthe full year system capacity to continue to increase in comparison tobe higher than 2022, partially offset by increases in the fuel efficiency of our fleet.

Profit Sharing. Our broad-based employee profit sharing program provides that for each year in which we have an annual pre-tax profit, as defined by the terms of the program, we will pay a specified portion of that profit to employees. In determining the amount of profit sharing, the program defines profit as pre-tax profit adjusted for profit sharing and certain other items. During the sixnine months ended JuneSeptember 30, 2023, we accrued $667 million$1.1 billion in profit sharing expense based on the year-to-date performance and current expectations for 2023 profit.

We paid $563 million in profit sharing in February 2023 related to our 2022 pre-tax profit in recognition of our employees' contributions toward achieving the year's financial results.

Pilot Agreement Payment. In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes numerous work rule changes and pay rate increases during the four-year term, including an initial pay rate increase of 18%. The agreement also includes a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million.

Sale of Miles to Participating Companies. Customers earn miles based on their spending with participating companies such as credit card companies, hotels, car rental agencies and ridesharing companies with which we have marketing agreements to sell miles. Payments are typically due to us monthly based on the volume of miles sold during the period. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. Total cash sales to American Express were $3.4$5.1 billion in the sixnine months ended JuneSeptember 30, 2023, an increase of approximately 30%26% compared to the prior year period.

Item 2. MD&A - Financial Condition and Liquidity
Investing Activities

Short-Term Investments. During the sixnine months ended JuneSeptember 30, 2023, we purchasedredeemed a net of $50 million$1.2 billion in short-term investments. See Note 3 of the Notes to the Condensed Consolidated Financial Statements for further information on these investments.

Capital Expenditures. Our capital expenditures were $2.5$3.7 billion and $2.7$4.2 billion for the sixnine months ended JuneSeptember 30, 2023 and 2022, respectively. Our capital expenditures are primarily related to the purchases of aircraft, airport construction projects, fleet modifications and technology enhancements.

We have committed to future aircraft purchases and have obtained, but are under no obligation to use, long-term financing commitments for a substantial portion of the purchase price of the aircraft. Excluding the New York-LaGuardia airport project discussed below, our expected 2023 capital spend of approximately $5.5 billion will be primarily for aircraft, including deliveries and advance deposit payments, as well as fleet modifications and technology enhancements and may vary depending on financing decisions.

New York-LaGuardia Redevelopment. As part of the terminal redevelopment project at LaGuardia Airport, we are partnering with the Port Authority of New York and New Jersey to replace Terminals C and D with a new state-of-the-art terminal facility. Construction is ongoing and is being phased to limit passenger inconvenience. Due to an acceleration effort that commenced in 2020, completion is expected by 2025.

We currently expect our net project costs to be approximately $4.3 billion and we bear the risks of project construction, including any potential cost over-runs. Using funding primarily provided by existing financing arrangements and other sources of funding, we expect to spend approximately $500 million on this project during 2023, of which $213$354 million was incurred in the sixnine months ended JuneSeptember 30, 2023.

Los Angeles International Airport ("LAX"). We have an ongoing terminal redevelopment project at LAX to modernize, update and provide post-security connection to Terminals 2 and 3. Construction is expected to be completed by the end of 2023 with a total cost of approximately $2.4 billion. A substantial majority of the project costs are being funded through the Regional Airports Improvement Corporation ("RAIC"), a California public benefit corporation, using a revolving credit facility provided by a group of lenders. We have guaranteed the obligations of the RAIC under the credit facility and the revolving credit facility agreement was most recently amended in the March 2023 quarter, decreasing the revolver capacity to $700 million. In the June 2023 quarter, the revolving credit facility agreement capacity was reduced to $626 million.

Wheels Up. We, along with Certares Management LLC, Knighthead Capital Management LLC and Cox Enterprises, Inc. announced the closing on September 20, 2023 of an expanded strategic partnership with Wheels Up, which includes an agreement for a $500 million credit facility to Wheels Up. At closing, the credit facility was comprised of a $350 million term loan, of which we contributed $150 million, and a $100 million liquidity facility that we made available to Wheels Up in the event the company's liquidity falls below $100 million. The terms of the credit facility permit one or more new lenders to provide an aggregate incremental $50 million term loan after the closing date. In connection with the closing, the term loan investors received newly issued shares of Wheels Up's common stock representing 80% of Wheels Up's outstanding equity as of the closing of the credit facility on a fully diluted basis. Upon approval by Wheels Up's stockholders of an amendment to its certificate of incorporation, Wheels Up is expected to issue to the lenders additional new shares such that the lenders will own 95% of Wheels Up's outstanding equity as of the closing of the credit facility on a fully diluted basis.

The $150 million cash contribution was reflected as an investing outflow in our Condensed Consolidated Statement of Cash Flows and allocated on a relative fair value basis to a loan receivable within other noncurrent assets and an equity investment on our balance sheet.

Financing Activities

Debt and Finance Leases. In the sixnine months ended JuneSeptember 30, 2023, we had cash outflows of $3.0$3.7 billion related to repayments of our debt and finance lease obligations, including $1.1$1.4 billion of principal amounts for the early repurchase of various secured and unsecured notes and a portion of the SkyMiles Term Loan on the open market and early principal repayments of $585 million on various notes secured by aircraft. Approximately $1.4$1.7 billion of the early repurchases and repayments were scheduled to mature after 2023.We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities.

In the March 2023 quarter, both Fitch and S&P credit rating agencies upgraded theour debt rating outlooks for Delta to stable and positive, respectively. In the September 2023 quarter, S&P upgraded our credit rating to BB+.

The principal amount of our debt and finance leases was $20.3$19.6 billion at JuneSeptember 30, 2023.

Item 2. MD&A - Supplemental Information
Supplemental Information

We sometimes use information (non-GAAP financial measures) that is derived from the Condensed Consolidated Financial Statements, but that is not presented in accordance with GAAP. Under the U.S. Securities and Exchange Commission rules, non-GAAP financial measures may be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results.

Included below are reconciliations of non-GAAP measures used within this Form 10-Q to the most directly comparable GAAP financial measures. Reconciliations below may not calculate exactly due to rounding. These reconciliations include certain adjustments to GAAP measures to provide comparability between the reported periods, if applicable, and for the reasons indicated below:

Third-party refinery sales. Refinery sales to third parties, and related expenses, are not related to our airline segment. Excluding these sales therefore provides a more meaningful comparison of our airline operations to the rest of the airline industry.

MTM adjustments and settlements on hedges. Mark-to-market ("MTM") adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period, and therefore we remove this impact to allow investors to better understand and analyze our core performance. Settlements represent cash received or paid on hedge contracts settled during the applicable period.

Restructuring charges. During 2020, we recorded restructuring charges for items such as fleet impairments and voluntary early retirement and separation programs following strategic business decisions in response to the COVID-19 pandemic. During 2022, we recognized adjustments to certain of those restructuring charges, representing changes in our estimates.

Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. The adjustment for aircraft fuel and related taxes allows investors to better understand and analyze our non-fuel costs and year-over-year financial performance.

Profit sharing. We adjust for profit sharing because this adjustment allows investors to better understand and analyze our recurring cost performance and provides a more meaningful comparison of our core operating costs to the airline industry.

One-time pilot agreement expenses. In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes numerous work rule changes and pay rate increases during the four-year term, including an initial pay rate increase of 18%. The agreement also includes a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million. Additionally, we recorded adjustments to other benefit-related items of approximately $130 million. Adjusting for these expenses allows investors to better understand and analyze our core cost performance.

Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. The adjustment for aircraft fuel and related taxes allows investors to better understand and analyze our non-fuel costs and year-over-year financial performance.

Item 2. MD&A - Supplemental Information
Free Cash Flow

The following table shows a reconciliation of net cash provided by operating and investing activities (GAAP measures) to free cash flow (a non-GAAP financial measure). We present free cash flow because management believes this metric is helpful to investors to evaluate the company's ability to generate cash that is available for use for debt service or general corporate initiatives. Adjustments include:

Net redemptions of short-term investments. Net redemptions of short-term investments represent the net purchase and sale activity of investments and marketable securities in the period, including gains and losses. We adjust for this activity to provide investors a better understanding of the company's free cash flow generated by our operations.

Strategic investments and related. Certain cash flows related to our investments in and related transactions with other airlines and associated companies, including Wheels Up in the September 2023 quarter, are included in our GAAP investing activities. We adjust for this activity because it provides a more meaningful comparison to our airline industry peers.

Net cash flows related to certain airport construction projects and other. Cash flows related to certain airport construction projects are included in our GAAP operating activities and capital expenditures. We have adjusted for these items because management believes investors should be informed that a portion of these capital expenditures from airport construction projects are either reimbursed by a third party or funded with restricted cash specific to these projects.

Financed aircraft acquisitions. This adjustment reflects aircraft deliveries that are leased as capital expenditures. The adjustment is based on their original contractual purchase price or an estimate of the aircraft's fair value and provides a more meaningful view of our investing activities.

Item 3. Market Risk
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in market risk from the information provided in "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in our Form 10-K.


ITEM 4. CONTROLS AND PROCEDURES

Our management, including our Chief Executive Officer and Chief Financial Officer, performed an evaluation of our disclosure controls and procedures, which have been designed to permit us to effectively identify and timely disclose important information. Our management, including our Chief Executive Officer and Chief Financial Officer, concluded that the controls and procedures were effective as of JuneSeptember 30, 2023 to ensure that material information was accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

During the three months ended JuneSeptember 30, 2023, we did not make any changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.


PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

"Item 3. Legal Proceedings" of our Form 10-K includes a discussion of our legal proceedings. ThereExcept as described below, there have been no material changes from the legal proceedings described in our Form 10-K.

Capacity Antitrust Litigation

In July 2015, a number of purported class action antitrust lawsuits were filed alleging that Delta, American, United and Southwest had conspired to restrain capacity. The lawsuits were filed in the wake of media reports that the U.S. Department of Justice had served civil investigative demands upon these carriers seeking documents and information relating to this subject. The lawsuits have been consolidated into a single Multi-District Litigation proceeding in the U.S. District Court for the District of Columbia. In August 2023, the Court denied the defendants’ motions for summary judgment that had been pending for over two years. In September 2023, we moved to certify the decision for an interlocutory appeal or for reconsideration. Briefing related to that motion will run through mid-November 2023, and class certification discovery will commence in the meantime. Delta believes the claims in these cases are without merit and is vigorously defending these lawsuits.


ITEM 1A. RISK FACTORS

“Item 1A. Risk Factors” of our Form 10-K includes a discussion of our known material risk factors, other than risks that could apply to any issuer or offering. There have been no material changes from the risk factors described in our Form 10-K.
