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, goals, aspirations, commitments 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, 2023 ("Form 10-K"), other than risks that could apply to any issuer or offering. All forward-looking statements speak only as of the date made, and we undertake no obligation to publicly update or revise any forward-looking statements to reflect events or circumstances that may arise after the date of this report except as required by law.

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 June 30, 2024, the related condensed consolidated statements of operations and comprehensive income and consolidated statements of stockholders' equity for the three-month and six-month periods ended June 30, 2024 and 2023, condensed consolidated statements of cash flows for the six-month periods ended June 30, 2024 and 2023, 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, 2023, the related consolidated statements of operations, comprehensive income, cash flows, and stockholders' equity for the year then ended, and the related notes (not presented herein); and in our report dated February 12, 2024, 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, 2023, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

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

Notes to the Condensed Consolidated Financial Statements

(Unaudited)

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, 2023.

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

Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and six months ended June 30, 2024 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.

NOTE 2. REVENUE RECOGNITION

Passenger Revenue



			Three Months Ended June 30,									Six Months Ended June 30,
(in millions)			2024			2023						2024			2023
Ticket			$	12,349		$	11,829					$	22,182		$	21,068
Loyalty travel awards			975			902						1,820			1,645
Travel-related services			517			474						970			903
Passenger revenue			$	13,841		$	13,205					$	24,972		$	23,616

Ticket

We recognized approximately $5.6 billion and $5.7 billion in passenger revenue during the six months ended June 30, 2024 and 2023, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods.

Loyalty Travel Awards

Loyalty travel awards revenue is related to the redemption of mileage credits ("miles") for air travel. Our SkyMiles loyalty program allows customers to earn 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, retail, ridesharing, car rental and hotel 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 six months ended June 30, 2024 and 2023, total cash sales from marketing agreements related to our loyalty program were $3.6 billion and $3.4 billion, 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, revenue is comprised of miles that were part of the loyalty program deferred revenue balance at the beginning of the period as well as miles that were issued during the period. The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned.

Delta Air Lines, Inc. | June 2024 Form 10-Q 7

Notes to the Condensed Consolidated Financial Statements

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.

Notes to the Condensed Consolidated Financial Statements

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:

Notes to the Condensed Consolidated Financial Statements

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

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

Long-Term Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. 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.

Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). We recognized gains of $16 million and losses of $80 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income ("income statement") for the three and six months ended June 30, 2024, respectively, compared to gains of $12 million and $43 million for the three and six months ended June 30, 2023, respectively. The losses recognized during the first six months of 2024 were composed of $28 million of mark-to-market losses and $52 million of settlement losses on contracts. Gains and losses on settled contracts are reflected within Monroe's operating results. See Note 9, "Segments," for further information on our Monroe refinery segment.

Availability Under Revolving Credit Facilities

As of June 30, 2024, we had approximately $2.9 billion undrawn and available under our revolving credit facilities.

Early Settlement of Outstanding Notes

During the six months ended June 30, 2024, through early principal repayments and open market repurchases, we extinguished an aggregate principal amount of $744 million related to a portion of the SkyMiles Term Loan and various secured and unsecured notes. These payments resulted in a $36 million loss on extinguishment of debt recorded in non-operating expense in our income statement.

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 underlying collateral. Debt is primarily classified as Level 2 within the fair value hierarchy.

NOTE 9. SEGMENTS

Refinery Operations

Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and from jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. We use several counterparties to exchange non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations.

Segment Reporting

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

NOTE 10. EARNINGS PER SHARE

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

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 2023 Form 10-K.

June 2024 Quarter Financial Highlights

Our operating income for the June 2024 quarter was $2.3 billion, a decrease of $224 million compared to the June 2023 quarter.

Revenue. Compared to the June 2023 quarter, our total revenue increased $1.1 billion, or 7%, due primarily to an 8% increase in capacity on strong operational performance. Passenger revenue increased 5% resulting from strength in travel demand, particularly for our premium products, partially offset by a decrease in yield. Total revenue, adjusted (a non-GAAP financial measure, which excludes revenue related to refinery sales to third parties) increased in the June 2024 quarter by $794 million, or 5.4%, compared to the June 2023 quarter.

Operating Expense. Total operating expense in the June 2024 quarter increased $1.3 billion, or 10%, compared to the June 2023 quarter, primarily due to higher employee costs from increased wages, higher fuel expense and increased costs associated with higher capacity. Total operating expense, adjusted (a non-GAAP financial measure, which primarily excludes expenses related to refinery sales to third parties) in the June 2024 quarter increased $1.0 billion, or 8%, compared to the June 2023 quarter.

Our total operating cost per available seat mile ("CASM") increased 2% compared to the June 2023 quarter. Non-fuel unit cost ("CASM-Ex", a non-GAAP financial measure) increased 0.6%, primarily due to higher employee costs from increased wages.

Cash Flow. Our cash, cash equivalents, short-term investments and aggregate undrawn principal amount available under our revolving credit facilities ("liquidity") as of June 30, 2024 was $7.2 billion.

During the June 2024 quarter, operating activities generated $2.5 billion, primarily from ticket sales. Total cash sales to American Express were $1.9 billion in the June 2024 quarter, an increase of approximately 9% compared to the June 2023 quarter.

Cash flows used in investing activities during the quarter totaled $809 million as capital expenditures were partially offset by redemptions of short-term investments. These operating and investing activities yielded free cash flow (a non-GAAP financial measure) of $1.3 billion in the June 2024 quarter. Additionally, we had cash outflows of $1.4 billion related to repayments of our debt and finance leases.

The non-GAAP financial measures referenced above for total revenue, adjusted, operating expense, adjusted, CASM-Ex and free cash flow are defined and reconciled in "Supplemental Information" below.

Domestic

Domestic passenger revenue increased 5% in the June 2024 quarter compared to the June 2023 quarter on an 8% increase in capacity and a stable load factor. We experienced strong revenue results across the domestic network, with coastal hub markets such as New York and Boston improving significantly compared to the prior year period.

International

International passenger revenue for the June 2024 quarter increased compared to the June 2023 quarter in each geographic region. Demand in the Atlantic region remains robust, with unit revenue down slightly compared to the June 2023 quarter primarily due to the impact from the summer Olympics on travel to Paris. The Pacific and Latin America regions accounted for the majority of international capacity growth on continued network restoration and improving connectivity with our international joint venture partners.

Refinery. Refinery sales to third parties increased $286 million compared to the June 2023 quarter. See "Refinery Segment" below for additional details on the refinery's operations, including third party refinery sales.

Loyalty Program. This relates to revenues from brand usage by third parties and other performance obligations embedded in miles sold, as well as redemption of miles for non-air travel and other awards. These revenues are mainly driven by customer spend on American Express cards and new cardholder acquisitions. Revenues from our relationship with American Express increased compared to the June 2023 quarter due to increased co-brand card spend and more premium card account acquisitions.

Miscellaneous. This is primarily composed of revenues related to lounge access, including access provided to certain American Express cardholders, codeshare agreements and certain other commercial relationships. The increase in revenues compared to the June 2023 quarter was primarily driven by codeshare and other commercial relationships.

The increase in salaries and related costs primarily resulted from the implementation of base pay increases for eligible employees of 5% effective June 1, 2024 and for Delta pilots on January 1, 2024. In June 2024 we also increased the minimum starting wage to $19 per hour.

Aircraft Fuel and Related Taxes. Aircraft fuel and related taxes increased $297 million compared to the June 2023 quarter primarily due to a 5% increase in the market price of jet fuel and a 7% increase in consumption on an 8% increase in capacity. We continue to expect that fuel consumption throughout 2024 will increase compared to 2023 aligned with capacity, partially offset by increases in the fuel efficiency of our fleet. The refinery also provided a benefit of six cents per gallon compared to a benefit of four cents per gallon in the June 2023 quarter. We expect jet fuel prices to remain volatile.

See "Refinery Segment" below for additional details on the refinery's operations.

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. Refinery sales to third parties increased $286 million compared to the June 2023 quarter. See "Refinery Segment" below for additional details on the refinery's operations, including third party refinery sales.

Landing Fees and Other Rents. The increase in landing fees and other rents primarily resulted from higher rates charged by airports following extensive redevelopment projects at numerous facilities and more flights compared to the June 2023 quarter that contributed to our increased capacity.

Aircraft Maintenance Materials and Outside Repairs. Aircraft maintenance materials and outside repairs increased compared to the June 2023 quarter primarily as a result of investments in the operational reliability of our fleet leading into the peak summer season and higher materials costs.

Other. The increase in other is primarily due to higher volume-related expenses associated with increased capacity, such as flight crew and other employee travel and incidental costs, and inflationary pressures.

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

Interest expense, net. Interest expense, net includes interest expense and interest income. This decreased compared to the prior year primarily due to reduced interest expense resulting from our debt reduction initiatives. During 2023, we made payments of approximately $4.1 billion related to our debt and finance lease obligations. We have continued to pay down our debt during the six months ended June 30, 2024 with $2.1 billion of payments on debt and finance lease obligations, including approximately $900 million of early repayments. This included early extinguishment of $744 million in principal related to a portion of the SkyMiles Term Loan and various secured and unsecured notes, and approximately $150 million on finance leases that were scheduled to be paid later in 2024. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities.

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

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

Miscellaneous, net. Miscellaneous, net primarily includes employee benefit plans net periodic cost, charitable contributions, our share of our equity method investments' results and foreign exchange gains/(losses).

Income Taxes

We project our annual effective tax rate for 2024 will be between 24% and 26%. In certain periods, we may have adjustments to our net deferred tax liabilities as a result of changes in prior year estimates, mark-to-market adjustments on our equity investments and tax laws enacted during the period, which will impact the effective tax rate for that period.

Item 2. MD&A - Refinery Segment

Refinery Segment

The refinery operated by Monroe primarily produces gasoline, diesel and jet fuel. Monroe exchanges non-jet fuel products the refinery produces with third parties for jet fuel consumed in our airline operations. The jet fuel produced and procured through exchanging gasoline and diesel fuel produced by the refinery typically provides approximately 200,000 barrels per day, or approximately 75% of our consumption, for use in our airline operations. The refinery regularly optimizes its sales and exchange activities based on market conditions. The refinery generated lower operating income in the six months ended June 30, 2024 compared to the six months ended June 30, 2023, primarily as a result of lower pricing in the first half of 2024.

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

Item 2. MD&A - Financial Condition and Liquidity

Financial Condition and Liquidity

As of June 30, 2024, we had $7.2 billion in cash, cash equivalents, short-term investments and aggregate undrawn principal amount available under our revolving credit facilities ("liquidity"). We expect to meet our liquidity needs for the next twelve months with cash and cash equivalents, short-term investments and cash flows from operations. We expect to meet our long-term liquidity needs with cash flows from operations and financing arrangements.

Undrawn Lines of Credit. As of June 30, 2024, we had approximately $2.9 billion undrawn and available under our revolving credit facilities.

Sources and Uses of Liquidity

Operating Activities

We generated cash flows from operations of $4.9 billion and $4.8 billion in the six months ended June 30, 2024 and 2023, respectively. We expect to continue generating positive cash flows from operations during the remainder of 2024.

Our operating cash flow is impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date. When we receive a cash payment at the time of sale, we record the cash received on advance sales as deferred revenue in air traffic liability. The air traffic liability typically increases during the winter and spring months as advance ticket sales grow prior to the summer peak travel season and decreases during the summer and fall months.

Fuel. Fuel expense represented approximately 20% of our total operating expense for the six months ended June 30, 2024 and 2023. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. For example, the market price for jet fuel was 5% higher in the June 2024 quarter compared to the June 2023 quarter after it was 15% lower in the March 2024 quarter compared to the March 2023 quarter. Fuel consumption was higher during the three and six months ended June 30, 2024 compared to the prior year period due to the increase in capacity. We continue to expect that fuel consumption throughout 2024 will increase compared to 2023 aligned with capacity, partially offset by increases in the fuel efficiency of our fleet.

Profit Sharing. We paid $1.4 billion in profit sharing payments in February 2024 related to our 2023 pre-tax profit in recognition of our employees' contributions toward achieving the year's financial results. This is an increase compared to our profit sharing payment made in February 2023 of $563 million related to our 2022 pre-tax profit.

Our broad-based employee profit sharing program provides that for each year in which we have an annual pre-tax profit, as defined by the terms of the program, we will pay a specified portion of that profit to eligible employees. In determining the amount of profit sharing, the program defines profit as pre-tax profit adjusted for profit sharing and certain other items. During the six months ended June 30, 2024, we accrued $644 million in profit sharing expense based on the year-to-date performance and current expectations for 2024 profit.

Sale of Miles to Participating Companies. Customers earn miles based on their spending with participating companies such as credit card, retail, ridesharing, car rental and hotel companies with which we have marketing agreements to sell miles. Payments are typically due to us monthly based on the volume of miles sold during the period. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. Total cash sales to American Express were $3.6 billion in the six months ended June 30, 2024, an increase of 7% compared to the prior year period. See Note 2 of the Notes to the Condensed Consolidated Financial Statements for further information regarding the cash sales from marketing agreements.

Item 2. MD&A - Financial Condition and Liquidity

Investing Activities

Short-Term Investments. During the six months ended June 30, 2024, we redeemed a net of $1.0 billion in short-term investments. See Note 3 of the Notes to the Condensed Consolidated Financial Statements for further information on these investments.

Capital Expenditures. Our capital expenditures were $2.5 billion for each of the six months ended June 30, 2024 and 2023. 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. Our expected 2024 capital spend of approximately $5.0 billion, excluding the New York-LaGuardia airport project discussed below, will be primarily for aircraft, including deliveries and advance deposit payments, as well as fleet modifications and technology enhancements and may vary depending on financing decisions.

New York-LaGuardia Redevelopment. As part of the terminal redevelopment project at LaGuardia Airport, we are partnering with the Port Authority of New York and New Jersey to replace Terminals C and D with a new state-of-the-art terminal facility. Construction is ongoing with completion expected by the end of 2024.

Using funding primarily provided by existing financing arrangements and other sources of funding, we expect to spend approximately $400 million on this project during 2024, of which $163 million was incurred in the six months ended June 30, 2024.

Financing Activities

Debt and Finance Leases. In the six months ended June 30, 2024, we had cash outflows of $2.1 billion related to repayments of our debt and finance lease obligations, including approximately $900 million of early repayments. This included early extinguishment of $744 million in principal related to a portion of the SkyMiles Term Loan and various secured and unsecured notes, and approximately $150 million on finance leases that were scheduled to be paid later in 2024. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities.

In February 2024, Moody's credit rating agency affirmed our credit rating and upgraded its outlook for Delta to positive.

Capital Return to Shareholders. In the June 2024 quarter, the Board of Directors approved a quarterly dividend of $0.10 per share, which we paid on June 4, 2024 for total cash dividends of $64 million. Total cash dividends for the six months ended June 30, 2024 were $128 million.

On June 20, 2024, the Board of Directors approved and we will pay a quarterly dividend of $0.15 per share on August 20, 2024 to shareholders of record as of July 30, 2024.

Covenants. We were in compliance with the covenants in our debt agreements at June 30, 2024.

Critical Accounting Estimates

There have been no material changes in our Critical Accounting Estimates from the information provided in the "Critical Accounting Estimates" section of "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Form 10-K.

Supplemental Information

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

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

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

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

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

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

•One-time pilot agreement expenses. In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement included a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million. Additionally, we recorded adjustments to other benefit-related items of approximately $130 million. Adjusting for these expenses allows investors to better understand and analyze our core cost performance.

Item 2. MD&A - Supplemental Information

Free Cash Flow

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

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

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

Delta Air Lines, Inc. | June 2024 Form 10-Q 33

Exhibit 10.1

TERMS OF 2024 RESTRICTED STOCK AWARD1

Participants: All members of Delta’s Board of Directors (the “Board”) who are not employees of Delta (“Non-Employee Directors”), which includes the Chair of the Board (the “Chair”). These directors are:


Maria Black			Michael P. Huerta
Willie CW Chiang			Vasant M. Prabhu
Greg Creed			Sergio A. L. Rial
David G. DeWalt			David S. Taylor (Chair)
Leslie D. Hale			Kathy N. Waller

Type of Award: Restricted Stock, as defined and granted under the Delta Air Lines, Inc. Performance Compensation Plan (the “Performance Compensation Plan”).

Grant Date: June 20, 2024

Number of

Shares: The number of shares of Restricted Stock granted to each Non-Employee Director other than the Chair equals the result of the following formula: $200,000 divided by Y, where

Y = the closing price of Delta Common Stock, par value $0.0001 per share, on the New York Stock Exchange on the Grant Date.

The number of shares of Restricted Stock granted to the Chair equals the result of the following formula: $320,000 divided by Y.

Partial Shares: Any partial shares resulting from the above formula will be ignored and the aggregate shares of Restricted Stock for each Non-Employee Director will be rounded up to the nearest whole ten shares.

Vesting: Each grant awarded to a Non-Employee Director under the terms of this Attachment A (a “2024 Grant”) will vest (the “Vesting Date”) on the earlier of (1) June 20, 2025 and (2) the date of Delta’s 2025 Annual Meeting of Stockholders, subject to such Non-Employee Director’s continued service as a member of the Board on the Vesting Date.

1 In accordance with these terms, each Non-Employee Director other than the Chair of the Board received 4,040 shares of Restricted Stock on June 20, 2024. This is equal to $200,000 divided by $49.61 (the closing price of Delta Common Stock on the New York Stock Exchange (“NYSE”) on June 20, 2024), rounded up to the nearest whole ten shares. The Chair of the Board received 6,460 shares of Restricted Stock on June 20,2024. This is equal to $320,000 divided by $49.61 (the closing price of Delta Common Stock on the NYSE on June 20, 2024), rounded up to the nearest whole ten shares.

Accelerated

Vesting: Notwithstanding the foregoing, accelerated vesting will occur prior to the Vesting Date as follows: individual 2024 Grants will immediately vest on the date such Non-Employee Director ceases to be a member of the Board due to death, Disability or Retirement. For purposes of the 2024 Grant, (1) “Disability” means the Non-Employee Director’s inability to perform his or her duties as a member of the Board for a period of 180 or more days as a result of a demonstrable injury or disease and (2) “Retirement” means retiring from the Board (i) at or after age 52 with at least ten years of service as a director; (ii) at or after age 68 with at least five years of service as a director; or (iii) at the Non-Employee Director’s mandatory retirement date.

Forfeiture: Except as expressly set forth above, a Non-Employee Director will immediately forfeit any unvested Restricted Stock on the date such Non-Employee Director ceases to be a member of the Board for any reason, other than due to death, Disability or Retirement.

Dividends: In the event a cash dividend is paid with respect to shares of Delta Common Stock at a time during which the 2024 Grant is unvested, the Non-Employee Director will be eligible to receive the dividend when the 2024 Grant vests.

Exhibit 10.2

Description of Certain Benefits

of Members of the Board of Directors and Executive Officers

Delta provides certain flight benefits to members of its Board of Directors and provides certain benefits to its executive officers. Delta reserves the right to change, amend or terminate these programs, consistent with their terms, at any time for any reason for both active and retired directors and employees.

Flight Benefits: As is common in the airline industry, Delta provides complimentary travel and certain Delta Sky Club privileges for members of the Board of Directors; executive officers; the director’s or officer’s spouse, domestic partner or designated companion (including, in certain circumstances, the director’s or officer’s surviving spouse or domestic partner); the director’s or officer’s children and parents; and, to a limited extent, other persons designated by the director or officer (“Flight Benefits”). Complimentary travel for such other persons is limited to an aggregate imputed value of $35,000 per year for the CEO and President; $20,000 per year for directors; $15,000 per year for executive vice presidents; and $12,500 per year for senior vice presidents. Delta reimburses directors and officers for associated taxes on complimentary travel with an imputed tax value of up to $40,000 per year for the CEO and President; $25,000 per year for directors; $20,000 per year for executive vice presidents; and $17,500 per year for senior vice presidents. Unused portions of the annual allowances described in the previous two sentences accumulate and may be carried into succeeding years during Board service or employment.

A director who retires from the Board at or after age 52 with at least 10 years of service as a director, at or after age 68 with at least five years of service as a director, or at his mandatory retirement date, may continue to receive Flight Benefits during retirement, except the unused portion of the annual allowances does not accumulate into succeeding years (“Retired Director Flight Benefits”). A director who served on the Board of Directors during the period beginning on the date Delta entered into the merger agreement with Northwest and ending on the date the merger occurred, or who joined the Board of Directors on the date the merger occurred, will receive, at the completion of his Board service (other than due to death or due to removal by stockholders for cause), a vested right to Retired Director Flight Benefits, regardless of the director’s age and years of service when his Board service ends. A director is not eligible to receive Retired Director Flight Benefits if the director engages in certain wrongful acts. The director designated by the Delta Master Executive Council, the governing body of the Delta unit of the Air Line Pilots Association, International, does not receive Flight Benefits or Retired Director Flight Benefits.

An executive officer who retires from Delta (i) at or after age 52 with at least 10 years of service, or (ii) at any age with at least 25 years of service (with at least 10 years of consecutive service from the officer’s most recent date of hire), may continue to receive Flight Benefits during retirement, except the unused portion of the annual allowances does not accumulate into succeeding years (“Retired Officer Flight Benefits”). An executive officer who is at least age 45 with 10 years of service and whose (i) employment is terminated without cause or for any other reason that would entitle that person to benefits under Delta’s Officer and Director Severance Plan (“Severance Plan”) and (ii) combined age and years of service equal 60 or more will be eligible for the Retired Officer Flight Benefits. In addition, for an executive officer that becomes eligible for benefits under Severance Plan but does not meet the definition of retirement or whose combined age and years of service do not equal at least 60, the executive officer will receive an allotment of 32 one-way positive-space flight passes after expiration of the Flight Benefits available under the Severance Plan. This allotment will continue until the fifth anniversary of the executive officer’s severance date or, if the officer has less than five years of service with Delta, the number of months the officer was employed with Delta. In exchange for certain non-competition, non-solicitation and confidentiality covenants for the benefit of Delta and a general release of claims against Delta, an officer who served in that capacity during the period beginning on the date Delta entered into the merger agreement with Northwest and ending on the date on which the merger occurred or who joined Delta from Northwest on the date the merger occurred and who had been a Northwest officer on the date Delta entered into the merger agreement, will receive, on his termination of employment (other than by death or by Delta for cause), a vested right to Retired Officer Flight Benefits, regardless of the officer’s age and years of service at his termination of employment.

Notwithstanding the foregoing, a person who is first elected to the Board of Directors or as an officer on or after June 8, 2009, will not receive reimbursement for taxes for Retired Director Flight Benefits or Retired Officer Flight Benefits, respectively. Delta also does not provide any reimbursement for taxes associated with travel by the surviving spouse or domestic partner of any director or officer.

Annual Physicals: Delta requires executive officers to obtain a comprehensive annual physical examination. Delta pays the cost of this required examination, which is limited to a prescribed set of preventive procedures based on the person’s age and gender.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	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, 2023. Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair statement of results for the interim periods presented. Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and six months ended June 30, 2024 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.

Ticket

We recognized approximately $5.6 billion and $5.7 billion in passenger revenue during the six months ended June 30, 2024 and 2023, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods.

Loyalty Travel Awards

Loyalty travel awards revenue is related to the redemption of mileage credits ("miles") for air travel. Our SkyMiles loyalty program allows customers to earn 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, retail, ridesharing, car rental and hotel 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 six months ended June 30, 2024 and 2023, total cash sales from marketing agreements related to our loyalty program were $3.6 billion and $3.4 billion, 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, revenue is comprised of miles that were part of the loyalty program deferred revenue balance at the beginning of the period as well as miles that were issued during the period. The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned.

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

Travel-Related Services

Travel-related services are primarily composed of services performed in conjunction with a passenger’s flight and include baggage fees, administrative fees and on-board sales.

Refinery. This represents refinery sales to third parties. See Note 9, "Segments," for more information on revenue recognition within our refinery segment.

Loyalty Program. This relates to revenues from brand usage by third parties and other performance obligations embedded in miles sold, which are included within the total cash sales from marketing agreements discussed above. This also includes the redemption of miles for non-air travel and other awards.

Ancillary Businesses. This includes revenues from aircraft maintenance services we provide to third parties and our vacation wholesale operations.

Miscellaneous. This is primarily composed of revenues related to lounge access, including access provided to certain American Express cardholders, codeshare agreements and certain other commercial relationships.

Revenue by Geographic Region

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

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

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

Long-Term Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. 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.

Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). We recognized gains of $16 million and losses of $80 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income ("income statement") for the three and six months ended June 30, 2024, respectively, compared to gains of $12 million and $43 million for the three and six months ended June 30, 2023, respectively. The losses recognized during the first six months of 2024 were composed of $28 million of mark-to-market losses and $52 million of settlement losses on contracts. Gains and losses on settled contracts are reflected within Monroe's operating results. See Note 9, "Segments," for further information on our Monroe refinery segment.

Availability Under Revolving Credit Facilities

As of June 30, 2024, we had approximately $2.9 billion undrawn and available under our revolving credit facilities.

Early Settlement of Outstanding Notes

During the six months ended June 30, 2024, through early principal repayments and open market repurchases, we extinguished an aggregate principal amount of $744 million related to a portion of the SkyMiles Term Loan and various secured and unsecured notes. These payments resulted in a $36 million loss on extinguishment of debt recorded in non-operating expense in our income statement.

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 underlying collateral. Debt is primarily classified as Level 2 within the fair value hierarchy.

In January 2024, we entered into a purchase agreement with Airbus for 20 A350-1000 aircraft, with an option to purchase an additional 20 widebody aircraft. Deliveries of these aircraft are scheduled to begin in 2026.

Legal Contingencies

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

Segment Reporting [Abstract]

SEGMENTS

Refinery Operations

Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and from jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. We use several counterparties to exchange non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations.

Segment Reporting

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

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

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

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2023. Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair statement of results for the interim periods presented. Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and six months ended June 30, 2024 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.
Cash Equivalents and Restricted Cash Equivalents	Cash Equivalents and Restricted Cash Equivalents. Cash equivalents generally consist of money market funds. Restricted cash equivalents generally consist of money market funds, time deposits, commercial paper and negotiable certificates of deposit. Restricted cash equivalents 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 as well as certain self-insurance obligations and airport commitments. Restricted cash equivalents are recorded in prepaid expenses and other on our Consolidated Balance Sheet ("balance sheet"). The fair value of these cash equivalents is based on a market approach using prices generated by market transactions involving identical or comparable assets.
Short-Term and Long-Term Investments	Short-Term Investments. The fair values of our short-term investments are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted market prices, interest rates, benchmark curves, credit ratings of the security and other observable information. These investments are expected to mature in one year or less. Long-Term Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. 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.
Fuel Hedge Contracts	Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe").
