Forward Looking Statements

Unless otherwise indicated or the context otherwise requires, the terms "Delta," "we," "us" and "our" refer to Delta Air Lines, Inc. and its subsidiaries.

FORWARD-LOOKING STATEMENTS

Statements in this Form 10-Q (or otherwise made by us or on our behalf) that are not historical facts, including statements about our estimates, expectations, beliefs, intentions, projections or strategies for the future, may be "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or our present expectations. Known material risk factors applicable to Delta are described in "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 ("Form 10-K"), other than risks that could apply to any issuer or offering.

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, 2021, the related condensed consolidated statements of operations and comprehensive loss, cash flows and stockholders' equity for the three-month periods ended March 31, 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 months ended March 31, 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 Loss ("income statement") based on relevant statistics (such as passenger counts). Beginning in the March 2021 quarter we are no longer 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 $325 million in the March 2020 quarter, and $1.4 billion in 2019, including $355 million in the March 2019 quarter. The remaining amounts in regional carrier expense represent payments to our regional carriers under capacity purchase agreements and the expenses of our wholly owned regional subsidiary, Endeavor Air, Inc.

NOTE 2. REVENUE RECOGNITION

Passenger Revenue



	Three Months Ended March 31,
(in millions)	2021		2020
Ticket	$	2,277	$	6,511
Loyalty travel awards	241		543
Travel-related services	230		515
Total passenger revenue	$	2,748	$	7,569

We recognized approximately $822 million and $2.8 billion in passenger revenue during the three months ended March 31, 2021 and 2020, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods.

In March 2021, we announced the extension of the validity of all passenger tickets and travel credits expiring in 2021 or purchased in 2021 to December 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 America with the exception of Basic Economy tickets.

Other Revenue



	Three Months Ended March 31,
(in millions)	2021		2020
Ancillary businesses and refinery	$	726	$	223
Loyalty program	368		474
Miscellaneous	93		174
Total other revenue	$	1,187	$	871

Loyalty Program. 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. 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 three months ended March 31, 2021 and 2020, total cash sales from marketing agreements related to our loyalty program were $760 million and $992 million, respectively, which are allocated to travel and other performance obligations.

Current Activity of the Loyalty Program. Miles are combined in one homogeneous pool and are not separately identifiable. Therefore, the 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 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.


Loyalty program activity
(in millions)	2021		2020
Balance at January 1	$	7,182	$	6,728

Travel miles redeemed	(241)		(543)
Non-travel miles redeemed	(10)		(28)
Balance at March 31	$	7,285	$	6,817

The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned.

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:

Short-term investments	5,789		3,919		1,870		—
Long-term investments	1,417		948		38		431

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 the Consolidated Balance Sheet ("balance sheet") and 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 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, 2021, the estimated fair value of our short-term investments was $5.6 billion, which approximates cost. Of these investments, $4.7 billion are expected to mature in one year or less, with the remainder maturing during 2022. 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 March 2021 quarter, due to its agreement to merge with Aspirational Consumer Lifestyle Corp ("Aspirational"), a publicly-traded special purpose acquisition company, our investment in Wheels Up was classified as Level 2. 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.

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

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 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.

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, 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.

Wheels Up. In February 2021, Wheels Up entered into a definitive agreement to become publicly-traded via a merger with Aspirational. The transaction is expected to close in the June 2021 quarter. We account for our investment using the fair value option, as this election better reflects the economics of our ownership interest, and we have recorded our investment primarily based on Aspirational’s stock price and information included in its public filings.

Other Investments. This category includes various investments that are accounted for at fair value or under the equity method, depending on our ownership interest and the level of influence conveyed by our investment. Included in this category are our investments in Grupo Aeroméxico, LATAM Airlines Group S.A. ("LATAM") and Virgin Atlantic, all of which are undergoing in-court or out-of-court restructurings, and the carrying values of these investments remain zero at March 31, 2021. In order to support our relationships with these carriers, we have provided them with strategic and operational assistance through their restructurings. We have notes payable of $480 million, which are recorded in current maturities of debt and finance leases, and receivables from those partners recorded within other noncurrent assets as of March 31, 2021.

Unsecured Payroll Support Program Extension Loans

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. In the March 2021 quarter, we received $2.9 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 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 billion in a grant and $828 million in an unsecured 10-year low interest loan. 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. These 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 million of noncurrent debt, net of discount, and $44 million in additional paid in capital, respectively.

Delta Air Lines, Inc. 2021 March Form 10-Q 12

Notes to the Consolidated Financial Statements

We have participated in the initial payroll support program, and as described above, the first extension of the payroll support program. A summary of the amounts received and warrants issued to date under these programs is set forth in the following table:


Summary of payroll support program activity
(in millions, except percentages)	Total Amount		Grant		Loan		Number of Warrants	Percentage of Outstanding Shares at March 31, 2021
Payroll Support Program (PSP1)	$	5,594	$	3,946	$	1,648	6.8	1.1	%
First Payroll Support Program Extension (PSP2) (1)	2,861		2,033		828		2.1	0.3	%

(1)During the March 2021 quarter $1.2 billion of this grant was recognized in government grant recognition in our income statement and $847 million is deferred in other accrued liabilities on our balance sheet as of March 31, 2021.

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.

2020 Term Loan

In 2020 we entered into a $1.5 billion term loan secured by certain slots, gates and routes. In the March 2021 quarter we repaid in full the term loan, which was scheduled to mature in April 2023, and incurred a $56 million loss on extinguishment of debt, which is recorded in miscellaneous, net in non-operating expense in the income statement.

Availability Under Revolving Facilities

As of March 31, 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, 2021, including approximately $400 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.

Covenants

Our debt agreements contain various affirmative, negative and financial covenants. We were in compliance with the covenants in these debt agreements at March 31, 2021.

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. 2021 March Form 10-Q 14

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 months ended March 31, 2021 and 2020 was $503 million and $831 million, respectively.

Segment Reporting

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

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 during the March 2021 quarter, which we expect to continue throughout 2021. 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 an 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 2021, 2020 and 2019, and our commentary includes comparisons of 2021 results to both 2020 and 2019 results.

March 2021 Quarter Financial Overview

Our pre-tax loss for the March 2021 quarter was $1.5 billion, including the $1.2 billion benefit related to recognition of a portion of the first payroll support program extension grant during the quarter. This represents a $2.5 billion decrease compared to the March 2019 quarter primarily resulting from a 60% decrease in revenue. Pre-tax loss, adjusted (a non-GAAP financial measure) was $2.9 billion, a decrease of $3.8 billion compared to the March 2019 quarter.

Revenue. Compared to the March 2019 quarter, our operating revenue decreased $6.3 billion, or 60%, due to reduced demand resulting from the COVID-19 pandemic.

Operating Expense. Total operating expense in the March 2021 quarter decreased $3.9 billion, or 41%, compared to the March 2019 quarter, primarily resulting from lower volume-related expenses, mainly fuel and passenger commissions and other selling expenses, recognition of the first payroll support program extension grant and significant cost reduction measures taken across all aspects of our operation in response to the COVID-19 pandemic. Total operating expense, adjusted (a non-GAAP financial measure) for the March 2021 quarter decreased $3.1 billion, or 33%, compared to the March 2019 quarter.

Non-Operating Results. Total non-operating expense was $117 million in the March 2021 quarter, $43 million higher than the March 2019 quarter, primarily due to higher interest expense as a result of our increased debt due to financing arrangements entered into during 2020, partially offset by mark-to-market gains on 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, 2021 was $16.6 billion. During the March 2021 quarter, operating activities provided $691 million, which included $2.0 billion from the first payroll support program extension grant. Also during the quarter we incurred $60 million of investing cash outflows, primarily from capital expenditures related to our airport redevelopment projects, the purchase of aircraft and fleet modifications, partially offset by the net redemption of short-term investments. These results generated $710 million of free cash flow (a non-GAAP financial measure) in the March 2021 quarter. Additionally, during the March 2021 quarter we repaid $1.8 billion on our debt and finance leases, of which $1.5 billion was early repayment of 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.

The above non-GAAP financial measures for pre-tax loss, adjusted, operating expense, adjusted, and free cash flow are defined and reconciled in "Supplemental Information" below.

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 carbon neutrality plan seeks to balance immediate actions (such as carbon offset credits from projects that maintain, protect and expand forests) and long-term solutions (such as sustainable aviation fuel and carbon sequestration technologies). We plan to spend more than $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 $20 million on credits that we purchased and retired during the March 2021 quarter.

Operating Revenue

Compared to the March 2019 quarter, our operating revenue decreased $6.3 billion, or 60%, due to reduced demand resulting from the COVID-19 pandemic. The decrease in operating revenue, on a 36% decrease in capacity, resulted in a 38% decrease in total revenue per available seat mile ("TRASM") and a 46% decrease in TRASM, adjusted compared to the March 2019 quarter. The revenue declines compared to the March 2020 quarter are attributable to these same factors, with the impact of the pandemic largely limited to the month of March in 2020.

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 during the March 2021 quarter.

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, but 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 in the spring and summer of 2021. The increase in passenger revenue from February 2021 to March 2021 is indicative of this increasing demand. We expect widespread vaccination to result in sustained demand improvement going forward, with recovery of domestic demand preceding the recovery of international demand in most regions.

We have historically generated cargo revenues 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 March 2021 quarter compared to the March 2020 and March 2019 quarters, in contrast to the decreases experienced in passenger revenue.

Passenger revenue decreased $4.8 billion, or 64%, compared to the March 2020 quarter. Passenger revenue per available seat mile ("PRASM") decreased 47%, and passenger mile yield decreased 13% on 32% lower capacity. Load factor decreased 28 points from the March 2020 quarter to 45%.

Passenger revenue decreased $6.5 billion, or 70%, compared to the March 2019 quarter. PRASM decreased 54%, and passenger mile yield decreased 15% on 36% lower capacity. Load factor decreased 38 points from the March 2019 quarter to 45%.

Domestic

Passenger unit revenue related to our domestic region for the March 2021 quarter decreased 53% with capacity down 27% compared to the March 2019 quarter 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 decline compared to the March 2020 quarter is attributable to these same factors, with the impact of the pandemic largely limited to the month of March in 2020.

We are planning for improvement to the demand environment, primarily from leisure customers, to continue throughout 2021, though still lower than the comparable periods in 2019. Throughout the latter half of the March 2021 quarter we have seen leisure customer bookings continue to improve, ending the quarter down approximately only 25% from March 2019 quarter levels. We remain optimistic about the ultimate recovery of business travel but are unable to predict the timing or extent of that recovery. As a result, we are planning for our domestic capacity to be approximately 20% lower in the June 2021 quarter than the June 2019 quarter.

Item 2. MD&A - Results of Operations

International

Passenger revenue related to our international regions decreased 81% with capacity down 51% compared to the March 2019 quarter, with similar declines compared to the March 2020 quarter. The reductions in revenue and capacity presented in the tables above were a result of continued reduced demand and government travel directives and quarantines significantly limiting or suspending air travel due to the COVID-19 pandemic. Additionally, many countries have implemented international testing requirements, which has slowed demand in the short-term but is expected to enable the long-term recovery of international air travel.

We expect this significantly lower demand environment to continue for an extended period, with improvement expected after the recovery in 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 adjust flight schedules accordingly.

The Atlantic and Pacific regions continue to be the most impacted by the restrictions described above. In December 2020, we became the first U.S. airline to offer flights between the U.S. and Europe that allow customers to avoid quarantine upon arrival after testing negative for the virus prior to travel and upon arrival in Amsterdam and Rome. We plan to continue this program to Rome through the June 2021 quarter, while also adding more routes and frequencies, including the addition of Milan as a destination.

The Latin America region has shown the most recovery of the international regions, with improving demand for leisure destinations in the Caribbean, Mexico and Central America. We expect that trend to continue into the June 2021 quarter with the recovery in the Atlantic and Pacific regions lagging behind Latin America.

Ancillary Businesses and Refinery. Ancillary businesses and refinery includes refinery sales to third parties, aircraft maintenance services we provide to third parties and our vacation wholesale operations. Refinery sales to third parties, which are at or near cost, increased approximately $540 million and $490 million compared to the March 2020 and March 2019 quarters, respectively. 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. The increase in refinery sales was partially offset by declines in revenue from aircraft maintenance services we provide to third parties, which decreased due to the reduction in flights operated worldwide. The March 2019 quarter results also included $52 million of revenue from Delta Private Jets, which was combined with Wheels Up in January 2020 and is no longer reflected in ancillary businesses and refinery.

Loyalty Program. Loyalty program revenues relate to brand usage by third parties and other performance obligations embedded in miles sold, including redemption of miles for non-travel awards. These revenues are mainly driven by customer spend on American Express cards, which declined at a less severe rate than air travel.

Miscellaneous. Miscellaneous revenue is primarily composed of lounge access and codeshare revenues. The volume of these transactions has fallen compared to the March 2020 and March 2019 quarters due to the impact of, and our response to, the COVID-19 pandemic, including reduced capacity and the temporary closure of certain lounges. We expect to reopen nearly all of our lounges by July 2021.

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 decreased significantly in the March 2021 quarter compared to the March 2020 and 2019 quarters. Operating expense decreased primarily due to the voluntary separation programs described below, the many cost reduction measures and programs implemented in response to the COVID-19 pandemic and the reduction in volume and selling-related costs. During 2021, as distribution of effective vaccines continues, travel restrictions and advisories ease and customer confidence continues to grow, we expect revenue and capacity to return and operating expense to 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 restored.

The discussion below is focused largely on the changes in certain operating expense line items compared to the March 2020 and March 2019 quarters that were not primarily driven by the reduction in capacity or revenue. These include many of the 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 actions taken as a result of decreased demand for air travel due to the COVID-19 pandemic. In the second half of 2020, approximately 18,000 employees elected to participate in voluntary separation programs, reducing our workforce by approximately 20%. Additionally, approximately 13,000 employees took voluntary unpaid leaves of absence during the March 2021 quarter.

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 recall approximately 1,700 pilots between March and October that had been placed on inactive status.

Aircraft Fuel and Related Taxes. Fuel expense decreased $961 million compared to the March 2019 quarter primarily due to a 43% decrease in consumption and 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% decrease in the market price of jet fuel. Consumption decreased on a combination of reduced capacity and improved fuel efficiency on an available seat mile basis. Additionally, during the March 2021 quarter, we purchased and retired approximately $20 million of carbon offset credits which relate to approximately 60% of the 13 million metric tons of carbon emissions generated by our airline segment from March 1 to December 31, 2020. In the table below, these costs are shown in environmental sustainability impact.

The table below also shows the impact of hedging and the refinery on fuel expense and average price per gallon.

(1)Market price for jet fuel at airport locations, including related taxes and transportation costs.

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 million and approximately $490 million compared to the March 2020 and March 2019 quarters, respectively. The increase in refinery costs was partially offset by lower expenses related to aircraft maintenance services we provide to third parties due to the reduction in flights operated worldwide. In addition, $44 million of costs related to services performed by Delta Private Jets in the March 2019 quarter were recorded in ancillary businesses and refinery prior to the combination of that business with Wheels Up in January 2020.

Regional Carrier Expense. Regional carrier expense decreased compared to the March 2020 and March 2019 quarters due to lower utilization of these carriers as a result of the overall reduced capacity.

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 longer 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 $325 million in the March 2020 quarter, and $1.4 billion in 2019, including $355 million in the March 2019 quarter. The remaining amounts in regional carrier expense represent payments to our regional carriers under capacity purchase agreements and the expenses of our wholly owned regional subsidiary, Endeavor Air, Inc.

Aircraft Rent. Most aircraft operating lease expenses are recorded in aircraft rent and are contractually fixed. Therefore, aircraft rent did not decline as our other operating expense line items did compared to the March 2020 and March 2019 quarters.

Restructuring charges. During 2020, we recorded restructuring charges, including certain accruals, following strategic business decisions in response to the COVID-19 pandemic. In the March 2021 quarter, we recognized $44 million of adjustments to certain of those restructuring charges, representing changes in our estimates.

Government Grant Recognition. In January 2021, we entered into a payroll support program extension agreement with the U.S. Department of the Treasury. In the March 2021 quarter, we received $2.9 billion in payroll support payments, which must be used exclusively for the payment of employee wages, salaries and benefits. The support payments included a grant of $2.0 billion that is being recognized as contra-expense in 2021 over the period that the funds are expected to benefit. We expect to fully recognize the grant proceeds from this first payroll support program extension by the end of the June 2021 quarter.

Delta Air Lines, Inc. 2021 March Form 10-Q 23

Item 2. MD&A - Results of Operations

We additionally expect to receive approximately $2.7 billion, including a grant of $1.9 billion, under a second extension of the payroll support program. The grant will also be recognized as contra-expense in 2021 over the period that the funds are expected to benefit. The amounts of the second extension of the payroll support program are estimated based on our share, and the structure of, the first extension of the payroll support program although actual amounts could differ from our estimates. See Note 5 of the Notes to the Condensed Consolidated Financial Statements for additional information on the payroll support program extensions.

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 in the March 2021 quarter was $361 million. However, we have begun reducing the total amount of interest expense by paying down 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 expense in the June 2021 quarter to be approximately $350 million.

Impairments and equity method losses. Impairments and equity method losses reflects our share of LATAM's and Grupo Aeroméxico's equity method results prior to their respective bankruptcy filings, and our share of Virgin Atlantic's equity method results. See Note 4 of the Notes to the Condensed Consolidated Financial Statements for additional information on our equity investments.

Gain/(loss) on investments, net. Gain/(loss) on investments, net reflects the gains and losses on our equity investments measured at fair value on a recurring basis. The March 2021 quarter gain is primarily due to the mark-to-market adjustment on our investment in Wheels Up. See Note 4 of the Notes to the Condensed Consolidated Financial Statements for additional information on our equity investments.

Miscellaneous, net. Miscellaneous, net primarily includes pension and related benefit/(expense), foreign exchange gains/(losses) and charitable contributions. The March 2020 quarter included the $240 million gain recognized as a result of the combination of Delta Private Jets with Wheels Up in January 2020.

Income Taxes

During 2021 interim periods, we will calculate our income tax expense by applying to any pre-tax loss/income an effective tax rate determined as if the year to date period is the annual period. Using this method, for the three months ended March 31, 2021 our effective tax rate was 22%. 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/income due to the impact of the COVID-19 pandemic.

Delta Air Lines, Inc. 2021 March Form 10-Q 24

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 March 2021 quarter, the refinery operated at 60% – 90% of normal production levels, largely due to the significant decrease in the demand for jet fuel, and expects production levels at the high end of that range during the June 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 decreased compared to the March 2020 and March 2019 quarters due to lower refinery run rates during the quarter, as well as lower pricing for refined products. The operating loss was higher in the March 2021 quarter as compared to the March 2019 quarter, which was mainly driven by the reduction in revenue and an increase in Renewable Identification Numbers ("RINs") compliance costs discussed below, and was partially offset by cost savings resulting from decreased production levels.

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 throughout the March 2021 quarter, with Monroe incurring $158 million in RINs compliance costs during the March 2021 quarter as compared to $27 million and $15 million in the March 2020 and March 2019 quarters, respectively.

Item 2. MD&A - Financial Condition and Liquidity

Financial Condition and Liquidity

As of March 31, 2021, we had $16.6 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.

Sources and Uses of Liquidity

Operating Activities

Operating activities in the three months ended March 31, 2021 provided $691 million compared to providing $1.9 billion in the three months ended March 31, 2019. As described above, we are planning for domestic demand recovery throughout 2021, with sustained demand improvement expected during the second half of 2021. If the demand environment evolves in that 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.

Domestic demand improved throughout the latter half of the March 2021 quarter as consumers gained confidence to travel and began buying tickets for travel further in advance. New bookings for travel departures beyond 60 days nearly equaled our historical booking patterns, driving an extension of the booking curve and reversing a three-quarter trend of decline in our air traffic liability. Travel credits represented approximately 50% of the air traffic liability as of March 31, 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% of our total operating expense for the three months ended March 31, 2021. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. As demand increases and capacity returns, we expect fuel consumption to increase compared to the comparable period of 2020, although we still expect it to be lower than the comparable period in 2019.

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 billion to these plans during April 2021 and we are evaluating up to $1.0 billion of additional voluntary contributions later in the year. 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. 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 $150 million of this charge was disbursed in cash payments to participants in the March 2021 quarter. We anticipate that a total of approximately $600 million in cash payments will be made to participants in 2021 with the remaining payments in 2022 and beyond.

Government Support Programs. See "Financing Activities" below for discussion of the impact to our liquidity from the payroll support program extensions.

Investing Activities

Short-Term Investments. During the three months ended March 31, 2021, we redeemed a net of $210 million 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 and $1.4 billion for the three months ended March 31, 2021 and 2019, respectively. Our capital expenditures during the three months ended March 31, 2021 were primarily related to our airport redevelopment projects, the purchases of aircraft, 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 airport project discussed below, our expected 2021 capital expenditures of approximately $2.5 billion will be primarily for aircraft, including deliveries and advance deposit payments, as well as aircraft 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, due to an acceleration effort that commenced in 2020, completion is now expected in 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 million was incurred in the three months ended March 31, 2021.

Financing Activities

Debt and Finance Leases. In the three months ended March 31, 2021, we repaid approximately $1.8 billion on our debt and finance leases, of which $1.5 billion was the early repayment of the term loan secured by certain of our slots, gates and routes. We plan to continue paying down our debt, in addition to periodic amortization and scheduled maturities, during the remainder of 2021.

The principal amount of our debt and finance leases was $29.3 billion at March 31, 2021.

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. In the March 2021 quarter, we received $2.9 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 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.

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 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. The reconciliations presented below of the non-GAAP measures used in this 10-Q may not calculate exactly due to rounding.

Pre-tax (loss)/income, adjusted

The following table shows a reconciliation of pre-tax (loss)/income (a GAAP measure) to pre-tax (loss)/income, adjusted (a non-GAAP financial measure). In the current period, pre-tax (loss)/income, adjusted excludes the following items directly related to the impact of COVID-19 and our response for comparability with the prior period:

•Restructuring charges. During 2020, we recorded restructuring charges, including certain accruals, following strategic business decisions in response to the COVID-19 pandemic. In the March 2021 quarter, we recognized $44 million of adjustments to certain of those restructuring charges, representing changes in our estimates.

•Government grant recognition. We recognized $1.2 billion of the grant proceeds from the first payroll support program extension as a contra-expense. We are recognizing the grant proceeds as contra-expense based on the periods that the funds are intended to compensate and expect to use all proceeds from the first payroll support program extension by the end of the June 2021 quarter.

•Impairments and equity method losses. These adjustments relate to recording our share of the losses recorded by our equity method investees.

•Loss on extinguishment of debt. This adjustment relates to early termination of a portion of our debt that was incurred during the COVID-19 pandemic.

We also regularly adjust pre-tax (loss)/income for the following items to determine pre-tax (loss)/income, adjusted for the reasons described below.

•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. 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. Adjusting for these gains/losses allows investors to better understand and analyze our core operational performance in the periods shown.

•Delta Private Jets adjustment. Because we combined Delta Private Jets with Wheels Up in January 2020, we have excluded the impact of Delta Private Jets from 2019 results for comparability.

Operating Expense, adjusted

The following table shows a reconciliation of operating expense (a GAAP measure) to operating expense, adjusted (a non-GAAP financial measure). In the current period, operating expense, adjusted excludes restructuring charges and government grant recognition, which, as discussed above under the heading pre-tax (loss)/income, adjusted, are directly related to the impact of the COVID-19 pandemic and our response. We also adjust operating expense for MTM adjustments and settlements on hedges and Delta Private Jets for the same reasons described above under the heading pre-tax (loss)/income, adjusted. We also adjust operating expense for the following item for the reasons described below.

•Third-party refinery sales. Refinery sales to third parties, and related expenses, are not related to our airline segment. Operating expense, adjusted therefore provides a more meaningful comparison of operating expenses from our airline operations to the rest of the airline industry.

CASM-Ex

The following table shows a reconciliation of operating cost per available seat mile ("CASM") (a GAAP measure) to CASM-Ex (a non-GAAP financial measure). In the current period, CASM-Ex excludes restructuring charges and government grant recognition, which, as discussed above under the heading pre-tax (loss)/income, adjusted, are directly related to the impact of the COVID-19 pandemic and our response. We adjusted for refinery sales to third parties for the same reason described above under the heading operating expense, adjusted. We adjust for Delta Private Jets for the same reason described above under the heading pre-tax (loss)/income, adjusted. We also adjust CASM for the following items to determine CASM-Ex for the reasons described below.

•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.

Free Cash Flow

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. 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.
