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 March 31,September 30, 2021, the related condensed consolidated statements of operations and comprehensive loss, cash flowsincome/(loss) and consolidated statements of stockholders' equity for the three-month and nine-month periods ended March 31,September 30, 2021 and 2020, the condensed consolidated statements of cash flows for the nine-month periods ended September 30, 2021 and 2020 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, 2020, the related consolidated statements of operations, comprehensive loss, cash flows, and stockholders' equity for the year then ended, and the related notes (not presented herein); and in our report dated February 12, 2021, 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, 2020, 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 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, 2020.

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 impacts from the COVID-19 pandemic and the uncertain pace of recovery, seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and nine months ended March 31,September 30, 2021 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.

Regional Carrier Expense

We previously allocated certain costs (such as landing fees and other rents, salaries and related costs and contracted services) to regional carrier expense in our Condensed Consolidated Statements of Operations and Comprehensive LossIncome/(Loss) ("income statement") based on relevant statistics (such as passenger counts). Beginning in the March 2021 quarter we are no longerceased performing this allocation and have reclassified the costs presented in prior periods to align with this presentation. This reclassification better reflects the nature of, and how management views, these regional carrier related expenses. This allocation was approximately $900 million in 2020, including $325approximately $200 million in the MarchSeptember 2020 quarter, and $1.4 billion in 2019, including $355approximately $360 million in the MarchSeptember 2019 quarter. The remaining amounts in regional carrier expense represent the accrual of payments to our regional carriers under capacity purchase agreements and the expenses of our wholly owned regional subsidiary, Endeavor Air, Inc.

In the March 2021 quarter, we announced the extension of the validity of all passenger tickets and travel credits expiring in 2021purchased or purchasedexpiring in 2021 to December 31, 2022. In addition, we have waived change fees for all tickets purchased through April 30, 2021, as well as eliminated change fees for domestic and international tickets originating from North AmericaAdditionally, with the exception of Basic Economy tickets.tickets, we eliminated change fees for tickets originating in North America and waived change fees for those originating outside of North America.

We estimate the value of tickets that will expire unused (“breakage”) and recognize revenue at the scheduled flight date. Our breakage estimates are primarily based on historical experience, ticket contract terms and customers’ travel behavior. Given the change in ticket validity terms made in 2021 and the uncertainty caused by the COVID-19 pandemic, our estimates of revenue that will be recognized from the air traffic liability for unused tickets may vary in future periods.

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 are recorded in prepaid expenses and other and cash restricted for airport construction on theour Consolidated Balance Sheet ("balance sheet") and. Restricted cash equivalents generally consist of money market funds, time deposits, commercial paper and negotiable certificates of deposit, which primarily relate to proceeds from debt issued to finance, among other things, a portion of the construction costs for our new terminal facilities at New York's LaGuardia Airport. 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. Short-term investments consist of U.S. government and agency securities. The fair values of these 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.

At March 31,As of September 30, 2021, the estimated fair value of our short-term investments was $5.6 billion, which approximates cost.$4.4 billion. Of these investments, $4.7$3.7 billion are expected to mature in one year or less, with the remainder maturing during 2022.by the first half of 2023. 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. Our long-term investments that are 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. In the MarchSeptember 2021 quarter, due to its agreement to merge with Aspirational Consumer Lifestyle CorpWheels Up Experience Inc. ("Aspirational"Wheels Up"), a publicly-traded special purpose acquisition company, became publicly traded and, as of September 30, 2021, our investment in Wheels Up wasis classified as Level 2.1. In the June 2021 quarter, Clear Secure, Inc. ("CLEAR") became publicly traded and our investment is classified as Level 1. In addition, 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 and forecasts provided by our investees. 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 our equity investments.

Notes to the 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.

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, other valuation techniques for investments in companies without publicly-traded shares and foreign currency fluctuations. We recorded gains of $262 million and losses of $112 million on our fair value investments during the three months ended March 31, 2021 and 2020, respectively.

Delta Air Lines, Inc. September 2021 Form 10-Q                                 10

Notes to the Consolidated Financial Statements
Our share of Unifi Aviation's financial results is recorded in contracted services in our income statement as this entity is integral to the operations of our business by providing services at our airport locations, while our share of other equity method investees' financial results is recorded in impairments and equity method losses in our income statement under non-operating expense. If an investment accounted for under the equity method experiences a loss in value that is determined to be other than temporary, we will reduce our carrying value of the investment to fair value and record the loss in impairments and equity method losses in our income statement.

Payroll Support Program Extension (PSP2). The Consolidated Appropriations Act, 2021 was enacted on December 27, 2020, and included an extension of the payroll support program created under the Coronavirus Aid, Relief and Economic SecurityCARES Act ("CARES Act") providing an additional $15 billion in grants and loans to be used forthe airline employee wages, salaries and benefits.industry. In January 2021, we entered into a payroll support program extension agreement with the U.S. Department of the Treasury. InDuring the Marchsix months ended June 30, 2021, quarter, we received $2.9a total of $3.3 billion in payroll support payments under this extension agreement, which must be usedwe were required to use exclusively for the payment of employee wages, salaries and benefits and iswere conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs from the date of the extension agreement through March 2021. Other conditions include prohibitions on share repurchases and dividends through March 2022 and certain limitations on executive compensation until October 2022. The Department of Transportation also has the authority until March 1, 2022 to require airlines that received payroll support program funds to maintain scheduled air service deemed necessary to any point served by the airline before March 1, 2020.

These support payments consisted of approximately $2.0$2.3 billion in a grant and $828$957 million in an unsecured 10-year low interest loan. In return, we entered into a promissory note for the loan and issued warrants to the U.S. Department of the Treasury to acquire approximately 2.4 million shares of Delta common stock. The loan bears interest at an annual rate of 1.00% for the first five years and the applicable Secured Overnight Financing Rate ("SOFR") plus 2.00% in the final five years. In return, we entered into a promissory note for the $828 million and issued warrants to the U.S. Department of the Treasury to acquire approximately 2.1 million shares of Delta common stock, representing approximately 0.3% of our outstanding shares. TheseThe warrants have an initial exercise price of $39.73 per share, subject to adjustment in certain cases, and a five-year term. We have recorded the value of the promissory note and warrants on a relative fair value basis as $784$905 million of noncurrent debt, net of discount, and $44$52 million in additional paid in capital, respectively.

Notes to the Consolidated Financial Statements
Early Settlement of Outstanding Notes

In July 2021, we completed a cash tender offer for an aggregate purchase price of $1.0 billion, excluding accrued and unpaid interest, of our outstanding 7.0% Senior Secured Notes due 2025 (the "2025 Notes"), 7.375% Notes due 2026 (the "2026 Notes") and 4.5% Senior Secured Notes due 2025 (the "2025 SkyMiles Notes"). As a result of the tender offer, we purchased 2025 Notes, included as 2020 Senior Secured Notes in the table above, with principal amount of $677 million for approximately $800 million and 2026 Notes, included in Unsecured Notes in the table above, with principal amount of $169 million for approximately $200 million. We did not purchase any of the 2025 SkyMiles Notes under the tender offer. In addition to the early settlement of the principal amount of the purchased notes, we recorded a loss of $166 million on extinguishment of debt in non-operating expense in our income statement.

Throughout the September 2021 quarter we also repurchased $262 million of various secured certificates, unsecured notes and a portion of the SkyMiles Term Loan on the open market. These payments resulted in a $17 million loss on extinguishment of debt.

Availability Under Revolving Facilities

As of March 31,September 30, 2021, we had approximately $2.6 billion undrawn and available under our revolving credit facilities. In addition, we had outstanding letters of credit as of March 31,September 30, 2021, including approximately $400$300 million that reduced the availability under our revolving credit facilities and approximately $300 million that did not affect the availability of our revolving credit facilities.

Fair Value of Debt

Market risk associated with our fixed- and variable-rate debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates. The fair value of debt, shown below, is principally based on reported market values, recently completed market transactions and estimates based on interest rates, maturities, credit risk and where applicable, underlying collateral. Debt is primarily classified as Level 2 within the fair value hierarchy.

Aircraft Orders

During the June and September 2021 quarters, we agreed with Airbus to add incremental aircraft to our order book by converting options for 55 A321neo aircraft into firm orders and replenishing 25 of our options. We expect to take delivery of our first A321neo in the first half of 2022, with deliveries of these aircraft continuing through 2027. Additionally, we agreed to move up 2 A350-900 deliveries and 1 A330-900neo delivery to occur in the second half of 2022.

During the June 2021 quarter, we agreed to acquire 29 B-737-900 aircraft and enter into leases for 7 A350-900 aircraft. Additionally, during the September 2021 quarter, we agreed to enter into leases for 2 incremental A350-900 aircraft. We began taking delivery of these preowned aircraft in the September 2021 quarter and deliveries are expected to continue through the first quarter of 2022. Phased entry into service is expected through the summer of 2023.

Legal Contingencies

We are involved in various legal proceedings related to employment practices, environmental issues, antitrust matters and other 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.

Delta Air Lines, Inc. September 2021 March Form 10-Q                                 1416

Notes to the Consolidated Financial Statements
Other Contingencies

General Indemnifications

We are the lessee under many commercial real estate leases. It is common in these transactions for us, as the lessee, to agree to indemnify the lessor and the lessor's related parties for tort, environmental and other liabilities that arise out of or relate to our use or occupancy of the leased premises. This type of indemnity would typically make us responsible to indemnified parties for liabilities arising out of the conduct of, among others, contractors, licensees and invitees at, or in connection with, the use or occupancy of the leased premises. This indemnity often extends to related liabilities arising from the negligence of the indemnified parties but usually excludes any liabilities caused by either their sole or gross negligence or their willful misconduct.

Our aircraft and other equipment lease and financing agreements typically contain provisions requiring us, as the lessee or obligor, to indemnify the other parties to those agreements, including certain of those parties' related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or other equipment.

We believe that our insurance would cover most of our exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft and other equipment lease and financing agreements described above. While our insurance does not typically cover environmental liabilities, we have insurance policies in place as required by applicable environmental laws.

Some of our aircraft and other financing transactions include provisions that require us to make payments to preserve an expected economic return to the lenders if that economic return is diminished due to specified changes in laws or regulations. In some of these financing transactions, we also bear the risk of changes in tax laws that would subject payments to non-U.S. lenders to withholding taxes.

We cannot reasonably estimate our potential future payments under the indemnities and related provisions described above because we cannot predict (1) when and under what circumstances these provisions may be triggered and (2) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.

Other

We have certain contracts for goods and services that require us to pay a penalty, acquire inventory specific to us or purchase contract-specific equipment, as defined by each respective contract, if we terminate the contract without cause prior to its expiration date. Because these obligations are contingent on our termination of the contract without cause prior to its expiration date, no obligation would exist unless such a termination occurs.

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 through jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. Due to the decrease in demand for jet fuel caused by the COVID-19 pandemic, the refinery has shifted production to more 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 nine months ended March 31,September 30, 2021 and 2020 was $503$629 million and $831$1.7 billion, respectively, compared to $249 million and $1.1 billion for the three and nine months ended September 30, 2020, respectively.

Segment Reporting

Segment results are prepared based on our internal accounting methods described below, with reconciliations to consolidated amounts in accordance with GAAP.

We calculate basic lossearnings/(loss) per share and diluted loss(loss) per share by dividing net lossincome/(loss) by the weighted average number of common shares outstanding, excluding restricted shares. AntidilutiveWe 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 awards, including stock options, restricted stock awards and warrants. Antidilutive common stock equivalents excluded from the diluted lossearnings per share calculation are not material.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Condensed Consolidated Financial Statements and the related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q and our audited consolidated financial statements and related notes included in our 2020 Annual Report on Form 10-K.

Our business and operating results for 2021 continue to be significantly impacted by the COVID-19 pandemic. However, as described further below, we have seen improvement in our business duringbeginning in March 2021 and progressing through the MarchSeptember 2021 quarter, which we expect to continue throughout 2021.continue. Given the drastic and unprecedented impact of the pandemic on our operating results in 2020, we believe that for the financial overview discussion below, a comparison of our results in 2021 to 2019 allows for ana better understanding of the full impact of the COVID-19 pandemic and the progress of our recovery. Throughout the remainder of this management's discussion and analysis, we present results for the three and nine months ended September 30, 2021, 2020 and 2019, and our commentary on results of operations, financial conditions and liquidity includes comparisons of 2021 results to both 2020 and 2019 results.2019.

MarchSeptember 2021 Quarter Financial Overview

Our pre-tax lossincome for the MarchSeptember 2021 quarter was $1.5 billion, including the $1.2$1.8 billion benefit related to recognition of a portion of the first payroll support program extensionremaining PSP3 grant during the quarter. This represents a $2.5 billion$415 million decrease in pre-tax income compared to the MarchSeptember 2019 quarter primarily resulting fromdue to a 60% decrease27% reduction in revenue.operating revenue, partially offset by the recognition of the remaining PSP3 grant. Pre-tax loss,income, adjusted (a non-GAAP financial measure) was $2.9 billion,$216 million, a decrease of $3.8$1.8 billion compared to the MarchSeptember 2019 quarter.

Revenue. Compared to the MarchSeptember 2019 quarter, our operating revenuedecreased $6.3$3.4 billion, or 60%27%, due primarily to reduced demand resulting from the COVID-19 pandemic.

Operating Expense. Total operating expense in the MarchSeptember 2021 quarter decreased $3.9$3.5 billion, or 41%34%, compared to the MarchSeptember 2019 quarter, primarily resulting from recognition of the remaining PSP3 grant, lower volume-related expenses, mainly fuel and passenger commissions and other selling expenses, recognition of the first payroll support program extension grantlower salaries and related costs and profit sharing, and significant cost reduction measures taken across all aspects of our operation in response to the COVID-19 pandemic. These decreases were partially offset by an increase in expenses related to refinery sales to third parties, reflected in ancillary business and refinery expense. Total operating expense, adjusted (a non-GAAP financial measure) for the MarchSeptember 2021 quarter decreased $3.1$2.6 billion, or 33%25%, compared to the MarchSeptember 2019 quarter.

Non-Operating Results. Total non-operating expense was $117$673 million in the MarchSeptember 2021 quarter, $43$549 million higher than the MarchSeptember 2019 quarter, primarily due to higher interest expense as a result of our increased debt due to financing arrangements entered into duringin 2020, partially offset bylosses on debt extinguishment and mark-to-market gainslosses on certain of our equity investments.

Cash Flow. Our cash, cash equivalents, short-term investments and aggregate principal amount committed and available to be drawn under our revolving credit facilities ("liquidity") at March 31,as of September 30, 2021 was $16.6$15.8 billion. During the MarchSeptember 2021 quarter, operating activities provided $691 million, which included $2.0 billion from the first payroll support program extension grant.generated $151 million. Also during the quarter, we incurred $60investing activities used $384 million, of investing cash outflows, primarily fromfor capital expenditures, partially offset by net redemptions of short-term investments. Capital expenditures primarily related to the purchase of aircraft, fleet modifications, our airport redevelopment projects the purchaseand technology enhancements. These activities resulted in $463 million of aircraft and fleet modifications, partially offset by the net redemption of short-term investments. These results generated $710 millionofnegative free cash flow (a non-GAAP financial measure) in the MarchSeptember 2021 quarter. Additionally,Also, during the MarchSeptember 2021 quarter we repaid $1.8had cash outflows of approximately $1.6 billion onrelated to repayments of our debt and finance leases, of which $1.5including approximately $1.3 billion wasfor early repayment ofrepayments and the term loan secured by certain of our slots, gates and routes and issued $924 million of debt primarily in connection with the first payroll support program extension.remainder from scheduled maturities.

Environmental Sustainability. In February 2020, we announced plans to invest $1.0 billion over the next 10 years in our effort to achieve carbon neutrality from March 1, 2020 forward, a commitment we have reiterated despite the challenges faced during the COVID-19 pandemic. Our plan to achieve airline carbon neutrality plan seeks to balance immediate actions (such asincludes the purchase and retirement of carbon offset credits from projects that maintain, protect and expand forests) and long-term solutions (such as well as increased use of sustainable aviation fuel and improved fuel efficiency from fleet renewal and operational initiatives. In the first nine months of 2021, we incurred $69 million of expense related to carbon sequestration technologies). We plan to spend more thanoffset credits. This amount consists of $30 million in 2021 to address 13 million metric tons of carbon emissions generated by our airline segment from March 1 to December 31, 2020 through carbon offset credits, including $20as well as an additional $39 million onfor the purchase and retirement of carbon offset credits thatrelated to a portion of our airline segment's 2021 carbon emissions.

The increase in 2020.operating revenue, which outpaced the 91% increase in capacity, resulted in a 56% increase in TRASM and a 64% increase in TRASM, adjusted.

The increase in third-party refinery sales resulted from the refinery's shift to producing more non-jet fuel products due to the decline in demand for jet fuel. See "Refinery Segment" below for additional details on the refinery's operations, including third-party refinery sales recorded in other revenue, during the March 2021 quarter.each period.

Passenger revenue during the month of March 2021 was approximately 50% higher than the month of February 2021, which is a higher increase than we have historically experienced in prior years between February and March. The length and severity of the reduction in travel demand due to the COVID-19 pandemic are uncertain, butremains uncertain; however, with continued distribution of effective vaccines and easing of travel advisories and restrictions, we believe customer confidence will continue to grow, leading to increased demand for the remainder of 2021, subject to seasonality-driven impacts. The September 2021 quarter started with July monthly revenue increasing over the prior month at a higher rate than our historical seasonality-based change. However, we experienced a temporary pause in demand in August and early September due to a rise in COVID-19 cases attributable to a variant of the COVID-19 virus. We expect domestic leisure travel to remain near 2019 levels, while we are experiencing a delay in the spring and summerreturn of 2021. The increase in passenger revenue from February 2021business travel as many companies are pausing or delaying return to March 2021 is indicative of this increasing demand.office plans. We expect widespread vaccinationcontinue to result in sustained demand improvement going forward, with recovery ofexpect domestic demand preceding the recovery ofto lead international demand recovery. We believe international demand recovery will continue to be uneven in most regions.the remainder of 2021 and the beginning of 2022. We continue to monitor risks to the pace of recovery from COVID-19 variants, the impact of vaccine programs and travel advisories and restrictions. We are planning for our system capacity to be approximately 20% lower in the December 2021 quarter than the December 2019 quarter.

We have historically generated cargo revenuesrevenue in domestic and international markets through the use of cargo space on regularly scheduled passenger aircraft. Reduced industry capacity as a result of the COVID-19 pandemic drove a significant increase in our cargo yield and our cargo revenue in the MarchSeptember 2021 quarter compared to the March 2020 and MarchSeptember 2019 quarters, in contrastquarter. Compared to the decreases experiencedSeptember 2020 quarter, our cargo revenue in passenger revenue.the September 2021 quarter increased due to continued higher yields as well as higher volume.

We are monitoring the Biden administration's recent announcement that will lift travel restrictions on all fully vaccinated foreign visitors to the United States beginning in November 2021. This action will make travel to the U.S. by many foreign nationals possible for the first time in 18 months. Despite this policy change, we expect thisthe significantly lower international demand environment to continue for an extended period,at least into early 2022, with improvement expected after the recovery inpace continuing to trail domestic travel. As a result, we are planning for our international capacity to be approximately 50% lower in the June 2021 quarter than the June 2019 quarter. In each of the international regions, we continue to monitor government travel directives and customer demand and will continue to adjust flight schedules accordingly.

In response to the reduced demand and related reduction in revenue following the onset of the COVID-19 pandemic in early 2020, we quickly reduced capacity to more closely align with demand, implemented cost saving initiatives related to our fleet and operations, offered employees voluntary separation programs and delayed or eliminated nearly all discretionary spending.

As a result, most operating expense line items decreasedremain significantly lower in the MarchSeptember 2021 quarter compared tothan in the March 2020 andSeptember 2019 quarters.quarter. Operating expense decreased primarily due to recognition of the voluntary separation programs described below, the manyremaining PSP3 grant, lower volume-related expenses, mainly fuel and passenger commissions and other selling expenses, lower salaries and related costs and profit sharing, and significant cost reduction measures and programs implementedtaken across all aspects of our operation in response to the COVID-19 pandemic andpandemic. During the reduction in volume and selling-related costs. DuringSeptember 2021 quarter, as distribution of effective vaccines continues,continued, travel restrictions and advisories easeeased and customer confidence continuescontinued to grow despite the negative impact of a variant of the COVID-19 virus, we expectsaw revenue and capacity to return and related operating expense toline items increase. However, we believe that a portion of the cost savings achieved during 2020 was structural in nature, which we expect to contribute to a lower non-fuel unit cost in the future as capacity is fully restored.

The discussion below is focused largely on the changes in certain operating expense line items compared to the MarchSeptember 2020 and MarchSeptember 2019 quarters that were not primarily driven by the reductionchange in capacity or revenue. These include many of thewhat are expected to be structural cost reduction measures and programs we implemented in response to the COVID-19 pandemic.

Salaries and Related Costs. The decrease in salaries and related costs compared to the March 2020 and March 2019 quarters is primarily due to actionsActions taken as a result of decreased demand for air travel due to the COVID-19 pandemic.pandemic had a significant impact on salaries and related costs, leading to a decrease compared to the September 2019 quarter. In the second half of 2020, approximately 18,000 employees elected to participate in voluntary separation programs, reducingwhich initially reduced our workforce by approximately 20%. Additionally,, though some of those positions have subsequently been filled. Since the beginning of 2021, we have hired approximately 13,0008,000 employees took voluntary unpaid leaves of absence during the March 2021 quarter.in certain areas, including flight operations and reservations and customer care, in order to support our operations as demand and capacity return.

Beginning in March 2020 and continuing through December 2020, salaries were reduced by 100% for our CEO and 50% for our other officers. In addition, work hours were reduced by 25% for all other management and most front-line employee work groups. On January 1, 2021, employees were restored to full work hours and we plan to recallhave recalled approximately 1,700 pilots between Marchfrom inactive status back to active service. Additionally, approximately 40,000 employees took voluntary unpaid leaves of absence during the September 2020 quarter. These actions resulted in higher salaries and October that had been placed on inactive status.

Aircraft Fuel and Related Taxes. Fuel expense decreased$961 $687 million compared to the MarchSeptember 2019 quarter primarily due to a 43%32% decrease in consumption, andpartially offset by a 18% decrease in the market price of jet fuel. Fuel expense decreased $578 million compared to the March 2020 quarter primarily due to a 38% decrease in consumption and an 11% decrease1% increase in the market price of jet fuel. Consumption decreased ondue to a combination of reduced capacity and improved fuel efficiency on an available seat mile basis.

Fuel expense increased $1.1 billion compared to the September 2020 quarter primarily due to a 102% increase in consumption on a comparable increase in capacity, and a 75% increase in the market price of jet fuel.

Additionally, during the MarchSeptember 2021 quarter, we purchased and retired approximately $20$29 million of carbon offset credits, which relate to approximately 60%a portion of the 13 million metric tons of2021 carbon emissions generated by our airline segment from March 1 to December 31, 2020.segment.

Ancillary Businesses and Refinery. Ancillary businesses and refinery includes expenses associated with refinery sales to third parties, aircraft maintenance services we provide to third parties and our vacation wholesale operations. Increased expenses were primarily related to refinery sales to third parties, which are at or near cost. Due to the decrease in demand for jet fuel, the refinery has shifted production to more non-jet fuel products, which increased the sales to third parties compared to the March 2019 quarter. The refinery cost of sales increased approximately $540$455 million and approximately $490$866 million compared to the MarchSeptember 2020 and MarchSeptember 2019 quarters, respectively. The increase in third-party refinery costssales compared to the September 2019 quarter resulted from the refinery's shift to producing and selling more non-jet fuel products due to the decline in demand for jet fuel compared to pre-pandemic levels. The increase compared to the September 2020 quarter was partially offsetdriven by higher pricing during the September 2021 quarter, with lower production and demand for both jet and non-jet fuel products in the September 2020 quarter. Compared to the September 2019 quarter, expenses related to aircraft maintenance services we provide to third parties decreased due to the reduction in flights operated worldwide.worldwide; however, compared to the September 2020 quarter these expenses increased due to higher levels of flying. In addition, $44$43 million of costs related to services performed by Delta Private Jets in the MarchSeptember 2019 quarter were recorded in ancillary businesses and refinery prior to the combination of that business with Wheels Up in January 2020.

Depreciation and Amortization. Depreciation and amortization decreased compared to the September 2020 and September 2019 quarters primarily due to the aircraft that were retired or impaired during 2020.

Regional Carrier Expense. Regional carrier expense decreased compared to the March 2020 and MarchSeptember 2019 quartersquarter due to lower utilization of these carriers as a result of the overall reduced capacity.capacity and increased compared to the September 2020 quarter due to an increase in utilization as a result of the increased demand discussed above.

We previously allocated certain costs (such as landing fees and other rents, salaries and related costs and contracted services) to regional carrier expense in our income statement based on relevant statistics (such as passenger counts). Beginning in the March 2021 quarter we are no longerceased performing this allocation and have reclassified the costs presented in prior periods to align with this presentation. This reclassification better reflects the nature of, and how management views, these regional carrier related expenses. This allocation was approximately $900 million in 2020, including $325approximately $200 million in the MarchSeptember 2020 quarter, and $1.4 billion in 2019, including $355approximately $360 million in the MarchSeptember 2019 quarter. The remaining amounts in regional carrier expense represent the accrual of payments to our regional carriers under capacity purchase agreements and the expenses of our wholly owned regional subsidiary, Endeavor Air, Inc.

Aircraft Maintenance Materials and Outside Repairs. Maintenance expense increased compared to both the September 2019 and September 2020 quarters as we returned aircraft to service and to support our operational reliability. The increase compared to the September 2020 quarter was particularly pronounced due to the significantly reduced capacity during the September 2020 quarter and the large number of aircraft we had parked during that time.

Aircraft Rent. Most aircraft operating lease expenses are recorded in aircraft rent and are contractually fixed. Therefore, the change in aircraft rent did not decline aswas more muted than our other operating expense line items, didwhen compared to the MarchSeptember 2019 and September 2020 and March 2019 quarters.

Restructuring charges.Charges. During 2020, we recorded restructuring charges including certain accruals,for items such as fleet impairments and voluntary early retirement and separation programs following strategic business decisions in response to the COVID-19 pandemic. In the MarchSeptember 2021 quarter, we recognized $44$33 million of net adjustments to increase certain of those restructuring charges, representing changes in our estimates.

Government Grant Recognition. In JanuaryDuring the nine months ended September 30, 2021, we entered intoreceived a total of $6.4 billion under payroll support program extension agreementagreements with the U.S. Department of the Treasury.

Operating Revenue

Compared to the nine months ended September 30, 2019, our operating revenue decreased $15.1 billion, or 43%, due to reduced demand resulting from the COVID-19 pandemic. The decrease in operating revenue, on a 32% decrease in capacity, resulted in a 16% decrease in TRASM and a 24% decrease in TRASM, adjusted compared to the nine months ended September 30, 2019.

Compared to the nine months ended September 30, 2020, our operating revenue increased $7.3 billion, or 56%, due to increased demand in 2021 compared to 2020. The increase in operating revenue, on a 46% increase in capacity, generated a 7% increase in TRASM and a 1% increase in TRASM, adjusted compared to the nine months ended September 30, 2020.

Domestic

Domestic passenger unit revenue for the nine months ended September 30, 2021 decreased 31% with capacity down 20% compared to the nine months ended September 30, 2019 as a result of reduced demand due to the COVID-19 pandemic and our policy to block middle seats on flights through April 30, 2021. The revenue increase in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 is attributable to the low levels of capacity and demand during the prior year period due to the COVID-19 pandemic and the ongoing recovery in the nine months ended September 30, 2021.

International

International passenger revenue for the nine months ended September 30, 2021 decreased 70% with capacity down 52% compared to the nine months ended September 30, 2019. Compared to the nine months ended September 30, 2020, international passenger revenue increased 16% with an increase in capacity of 43%.

Aircraft Fuel and Related Taxes. Fuel expense decreased $2.5 billion compared to the nine months ended September 30, 2019 primarily due to a 37% decrease in consumption and an 8% decrease in the market price of jet fuel. Consumption decreased due to a combination of reduced capacity and improved fuel efficiency on an available seat mile basis.

Fuel expense increased $1.6 billion compared to the nine months ended September 30, 2020 due to a 41% increase in consumption and a 15% increase in the market price per gallon of jet fuel. Consumption increased with capacity during the nine months ended September 30, 2021 as described above; however, the impact was partially mitigated by improved fuel efficiency on an available seat mile basis.

Additionally, during the nine months ended September 30, 2021, we purchased and retired $69 million of carbon offset credits, which relate to 13 million metric tons of carbon emissions generated by our airline segment from March 1 to December 31, 2020 as well as a portion of our 2021 carbon emissions.

Interest expense, net. Interest expense increased compared to the prior year periods as a result of financing arrangements entered into during 2020. See Note 5 of the Notes to the Condensed Consolidated Financial Statements for additional information on recent financings. As a result of the increase in our outstanding debt since the onset of the COVID-19 pandemic, interest expense, net was $314 million in the MarchSeptember 2021 quarter was $361 million.

We have begun reducing the total amount of interest expense by paying downpre-paying our debt in addition to periodic amortization payments and scheduled maturities.This began with early repayments made during the December 2020 quarter and continued with the early repayment of our $1.5 billion secured term loan in the March 2021 quarter. We expect interest expensequarter, approximately $450 million of various EETCs in the June 2021 quarter, and approximately $850 million of certain notes through a cash tender offer and $262 million of other secured certificates, unsecured notes and a portion of the SkyMiles Term Loan through repurchases on the open market in the September 2021 quarter. Interest expense, net on our outstanding debt as of September 30, 2021 is expected to be approximately $350 million.$310 million during the December 2021 quarter. We continue to seek selective opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities, during the remainder of 2021 and beyond.

Income Taxes

During 2021 interim periods, we will calculateare calculating our income tax expense by applying to any pre-tax loss/incomeincome/(loss) an effective tax rate determined as if the year to date period is the annual period. Using this method, for the three and nine months ended March 31,September 30, 2021, our effective tax rate was 22%.21% and 13%, respectively. We believe that, at this time, this method for determining the effective tax rate is more reliable than projecting an annual effective tax rate due to the uncertainty of estimating annual pre-tax loss/incomeincome/(loss) due to the impact of the COVID-19 pandemic.

Item 2. MD&A - Refinery Segment
Refinery Segment

The refinery operated by our subsidiaries Monroe Energy, LLC and MIPC, LLC (collectively, "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. Historically, the jet fuel produced and procured through exchanging gasoline and diesel fuel produced by the refinery provided approximately 200,000 barrels per day, or approximately 75%, of our pre-COVID-19 pandemic consumption, for use in our airline operations. We believe that the jet fuel supply resulting from the refinery's operation contributes to reducing the market price of jet fuel and thus lowers our cost of jet fuel compared to what it otherwise would be.

The refinery’s production has also been altered by the dramatic change in economic conditions caused by the COVID-19 pandemic. During the Marchnine months ended September 30, 2021, quarter, the refinery operatedprogressively increased operations, ending the period at 60% – 90% of normalclose to pre-pandemic production levels, largely duewhich we expect to the significant decrease in the demand for jet fuel, and expects production levels at the high end of that rangecontinue during the JuneDecember 2021 quarter, subject to market conditions. Additionally, due to the decrease in demand for jet fuel, the refinery has shifted production to more non-jet fuel products. We plan to continue to exchange those non-jet fuel products for jet fuel to the extent needed based on jet fuel demand.

Refinery revenues increased compared to the three months ended September 30, 2019 due to increased sales to third parties and increased compared to the three and nine months ended September 30, 2020 due to higher pricing and increased production and demand experienced since the prior year period. The refinery revenues slightly decreased compared to the March 2020 and Marchnine months ended September 30, 2019 quarters due to lower refinery run rates during the quarter, as well asand lower pricing for refined products. The operating lossproducts in the first half of 2021. Operating income was higher in the Marchthree months ended September 30, 2021 quarter as compared to the March 2019 quarter, which was mainly driven by the reduction in revenueprior periods due to increased production and an increase inpricing, and lower Renewable Identification Numbers ("RINs") compliance costs discussed below. The operating loss was higher in the nine months ended September 30, 2021 as compared to the prior periods, mainly driven by an increase in RINs compliance costs discussed below, andwhich was partially offset by cost savings resulting from decreased production levels.levels compared to the nine months ended September 2019.

A refinery is subject to annual U.S. Environmental Protection Agency 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 requirement in the secondary market. Observable RINs prices increased throughoutthrough the Marchfirst half of 2021, quarter, withand declined during the September 2021 quarter. Monroe incurring $158incurred $44 million and $453 million in RINs compliance costs during the Marchthree and nine months ended September 30, 2021 quarter as compared to $27$25 million and $15$78 million in the Marchthree and nine months ended September 30, 2020, and March 2019 quarters, respectively.

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

As of March 31,September 30, 2021, we had $16.6$15.8 billion in cash, cash equivalents, short-term investments and aggregate principal amount committed and available to be drawn under our revolving credit facilities. We expect to meet our liquidity needs for the next twelve months with cash and cash equivalents, short-term investments, government assistance under the payroll support program extensions, restricted cash equivalents and cash flows from operations. We expect to meet our long-term liquidity needs with cash flows from operations and financing arrangements. We are continuing to evaluate the appropriate level of liquidity to maintain following the COVID-19 pandemic though, at least in the near term, we expect this level to be higher than the liquidity maintained prior to the pandemic.

Sources and Uses of Liquidity
Operating Activities

Operating activities in the threenine months ended March 31,September 30, 2021 provided $691 million$2.7 billion compared to using $2.5 billion and providing $1.9$7.5 billion in the threenine months ended March 31, 2019.September 30, 2020 and 2019, respectively. As described above, we are planning forexperiencing a domestic demand recovery throughout 2021, with sustained demand improvement expected duringand expect this to continue through the second halfend of 2021. If the demand environment evolvescontinues to evolve in thatthis manner, we expect to generate positive cash flows from operations, including funds received from the government support programs described in "Financing Activities" below, during 2021.

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 advanced ticket sales grow prior to the summer peak travel season and decreases during the summer and fall months. However, the current reduction in demand for air travel due to the COVID-19 pandemic has resulted in a lower level of advance bookings and the associated cash received than we have historically experienced.experienced, which has impacted the typical seasonal trend of air traffic liability since March 2020.

Domestic demand has improved throughoutsince the latter half of the March 2021 quarter as consumers gainedhave regained confidence to travel and began buying ticketsincreased ticket purchases for travel further in advance. New bookings for travel departures beyond 60 days nearly equaled our historical booking patterns, driving an extensionWe experienced a small moderation in demand growth in August and September 2021 due to a rise in COVID-19 cases attributable to a variant of the booking curve and reversing a three-quarter trendCOVID-19 virus; however, in the month of decline in our air traffic liability. Travel credits represented approximately 50% of theSeptember 2021, domestic leisure bookings approached September 2019 levels. Our air traffic liability remains above historical September quarter levels with travel credits representing approximately 40% of the balance as of March 31,September 30, 2021. See Note 2 of the Notes to the Condensed Consolidated Financial Statements for additional information on travel credits and our air traffic liability.

Fuel. Fuel expense represented approximately 18%22% of our total operating expense for the threenine months ended March 31,September 30, 2021. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. During the nine months ended September 30, 2021, our average fuel price per gallon was slightly below the same period of 2019, but fuel prices have recently increased and our average fuel price per gallon is projected to be higher in the December 2021 quarter than the nine months ended September 30, 2021. As demand increasescontinues to increase and capacity returns, we expect fuel consumption in the December 2021 quarter to increase compared to the comparable period ofDecember 2020 quarter, although we still expect it to be lower than the comparable period in 2019.December 2019 quarter.

Employee Benefit Obligations. We sponsor defined benefit pension plans for eligible employees and retirees. These plans are closed to new entrants and are frozen for future benefit accruals. Our funding obligations for these plans are governed by the Employee Retirement Income Security Act, as modified by the Pension Protection Act of 2006. We have no minimum funding requirements for our defined benefit pension plans in 2021. However, we voluntarily contributed $1.0$1.5 billion to these plans during Aprilthe June 2021 and we are evaluating up to $1.0 billion of additional voluntary contributions later in the year.quarter. At this level of funding, investment returns are expected to satisfy future benefit payments, which we believe would eliminate further material voluntary or required cash contributions to the plans, under the terms of the Pension Protection Act of 2006. Further, based on this level of funding, we have modified, and continue to evaluate, the asset allocation mix to reduce the investment risk of the portfolio and protect the plans' funded status. Estimates of future funding requirements are based on various assumptions and could vary materially from actual funding requirements. Assumptions include, among other things, the actual and projected market performance of assets, statutory requirements and demographic data for participants.

Voluntary Separation Programs. In 2020, we recorded a $3.4 billion charge associated with voluntary early retirement and separation programs and other employee benefit charges. Approximately $150In the nine months ended September 30, 2021, $435 million of this charge was disbursed in cash payments to participants in the March 2021 quarter.addition to $720 million disbursed in 2020. We anticipate that a total of approximately $600 million in cash payments will be made to participants in 2021 and approximately $500 million in 2022 with the remaining payments in 20222023 and beyond.

Investing Activities

Short-Term Investments. During the threenine months ended March 31,September 30, 2021, we redeemed a net of $210 million$1.4 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 $438 million$2.0 billion and $1.4$3.9 billion for the threenine months ended March 31,September 30, 2021 and 2019, respectively. Our capital expenditures during the threenine months ended March 31,September 30, 2021 were primarily related to our airport redevelopment projects, the purchases of aircraft, fleet modifications, our airport redevelopment projects 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 2021 capital expenditures of approximately $2.5$3.2 billion, which may vary depending on financing decisions, will be primarily for aircraft, including deliveries and advance deposit payments, as well as aircraftfleet modifications and technology enhancements.

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 (“Port Authority”) to replace Terminals C and D with a new state-of-the-art terminal facility. Construction is underway and will be phased to limit passenger inconvenience and, dueinconvenience. Due to an acceleration effort that commenced in 2020, completion is now expected inby 2025.

We currently expect our project costs to be approximately $3.5 billion and we bear the risks of project construction, including any potential cost over-runs. Using funding primarily provided by existing financing arrangements, we expect to spend approximately $900 million on this project during 2021, of which $218$709 million was incurred in the threenine months ended March 31,September 30, 2021.

Financing Activities

Debt and Finance Leases. In the threenine months ended March 31,September 30, 2021, we repaidhad cash outflows of approximately $1.8$4.7 billion onrelated to repayments of our debt and finance leases, of which $1.5including approximately $3.3 billion wasfor the early repayment of the term loan secured by certain of our slots, gates and routes.routes, various EETCs, certain notes through a cash tender offer and other various unsecured notes, secured certificates and SkyMiles term loan. We plancontinue to continue paying downseek selective opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities, during the remainder of 2021.2021 and beyond.

Government Support Programs. The Consolidated Appropriations Act, 2021 was enacted on December 27, 2020, and included an extension of the payroll support program created under the Coronavirus Aid, Relief and Economic Security Act ("CARES Act") providing an additional $15 billion in grants and loans to be used for airline employee wages, salaries and benefits. In January 2021, we entered into a payroll support program extension agreement with the U.S. Department of the Treasury. InDuring the Marchsix months ended June 30, 2021, quarter, we received $2.9a total of $3.3 billion in payroll support payments which must be used exclusively for the payment of employee wages, salaries and benefits and is conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs from the date of theunder this extension agreement through March 2021. Other conditions include prohibitions on share repurchases and dividends through March 2022 and certain limitations on executive compensation until October 2022. The Department of Transportation also has the authority until March 1, 2022 to require airlines that received payroll support program funds to maintain scheduled air service deemed necessary to any point served by the airline before March 1, 2020.

The loan bears interest at an annual rate of 1.00% for the first five years and the applicable Secured Overnight Financing Rate ("SOFR") plus 2.00% in the final five years. In return, we entered into a promissory note for the $828 millionloan and issued warrants to the U.S. Department of the Treasury to acquire approximately 2.12.4 million shares of Delta common stock, representing approximately 0.3% of our outstanding shares.

Item 2. MD&A - Financial Condition and Liquidity
The American Rescue Plan Act of 2021 was enacted on March 11, 2021, and included a second extension of the payroll support program providing an additional $14 billion in grants and loans to be used for airline employee wages, salaries and benefits. We expect to enter into similar agreements as those discussed above with the U.S. Department of the Treasury. Based on the share of funds we received from the first extension of the payroll support program, and the similar structures of both extensions, we estimate that we will receive approximately $2.7 billion, consisting of $1.9 billion in a grant and $800 million in an unsecured 10-year low interest loan. However, the actual amounts received and the allocation between the grant and loan could differ from our estimates. These payments are expected to be conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs through September 2021 or the date on which assistance provided under the agreement is exhausted, whichever is later. Other conditions would include prohibitions on share repurchases and dividends through September 2022 and certain limitations on executive compensation until April 2023. In return, we expect to enter into a promissory note for the amount of the loan and to issue warrants to the U.S. Department of the Treasury to acquire shares of Delta common stock in an amount to be determined consistent with the structure of the prior warrant issuances.

Undrawn Lines of Credit

Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period. Settlements represent cash received or paid on hedge contracts settled during the applicable period.

Equity investment MTM adjustments. We adjust for our proportionate share of our equity method investee, Virgin Atlantic’s, hedge portfolio MTM adjustments (recorded in non-operating expense) to allow investors to understand and analyze our core operational performance in the periods shown.

MTM adjustments on investments. Unrealized gains/losses result from our equity investments that are accounted for at fair value in non-operating expense. These gains/losses are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in companies without publicly-traded shares.shares and foreign currency fluctuations. Adjusting for these gains/losses allows investors to better understand and analyze our core operational performance in the periods shown.

Adjustments include:

Net redemptions(redemptions)/purchases of short-term investments. Net redemptions(redemptions)/purchases 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. Cash flows related to our investments in and related transactions with other airlines 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, which were primarily funded by cash restricted for airport construction, to provide investors a better understanding of the company's free cash flow and capital expenditures that are core to our operational performance in the periods shown.
