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.

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, 2024, the related condensed consolidated statements of operations and comprehensive income/(loss), condensed consolidated statements of cash flows, and consolidated statements of stockholders' equity for the three-month periods ended March 31, 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 months ended March 31, 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 March 31,
(in millions)	2024		2023
Ticket	$	9,833	$	9,239
Loyalty travel awards	844		743
Travel-related services	454		429
Passenger revenue	$	11,131	$	10,411

Ticket

We recognized approximately $3.9 billion in passenger revenue during both the three months ended March 31, 2024 and 2023 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 three months ended March 31, 2024 and 2023, total cash sales from marketing agreements related to our loyalty program were $1.8 billion and $1.7 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. | March 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.

Miles redeemed for non-air travel and other	(56)		(40)
Balance at March 31	$	8,541	$	8,098

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.

Other Revenue

Other revenue	$	2,439	$	2,139

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 aircraft maintenance services we provide to third parties and our vacation wholesale operations.

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

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 losses of $96 million and gains of $31 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income/(Loss) ("income statement") for the three months ended March 31, 2024 and 2023, respectively. The losses recognized during the first three months of 2024 were composed of $27 million of mark-to-market losses and $69 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.

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.

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/(LOSS) PER SHARE

We calculate basic earnings/(loss) per share and diluted loss per share by dividing net income/(loss) 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/(loss) 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.

March 2024 Quarter Financial Highlights

Our operating income for the March 2024 quarter improved $891 million compared to the March 2023 quarter to $614 million for the reasons discussed below.

Revenue. Compared to the March 2023 quarter, our total revenue increased $989 million, or 8%, due primarily to a 7% increase in capacity and continued strength in travel demand across all geographic regions, particularly for our premium products. Total revenue, adjusted (a non-GAAP financial measure, which excludes revenue related to refinery sales to third parties) increased in the March 2024 quarter by $721 million, or 6%, compared to the March 2023 quarter.

Operating Expense. Total operating expense in the March 2024 quarter increased $98 million, or 1%, compared to the March 2023 quarter, primarily due to higher employee costs from increased wages and profit sharing and increased costs associated with higher capacity, partially offset by the one time pilot agreement-related expenses in 2023. Total operating expense, adjusted (a non-GAAP financial measure) in the March 2024 quarter increased $627 million, or 6%, compared to the March 2023 quarter. Adjustments were primarily to exclude expenses related to refinery sales to third parties and the one time pilot agreement-related expenses in 2023.

Our total operating cost per available seat mile ("CASM") decreased 6% compared to the March 2023 quarter, primarily due to a 7% increase in capacity, as well as the one time pilot agreement-related expenses in 2023. Non-fuel unit cost ("CASM-Ex", a non-GAAP financial measure) increased 1.5%, primarily due to higher employee costs from increased wages and profit sharing.

Cash Flow. Our cash, cash equivalents, short-term investments and aggregate undrawn principal amount available under our revolving credit facilities ("liquidity") as of March 31, 2024 was $7.4 billion.

During the March 2024 quarter, operating activities generated $2.4 billion. Cash flows from operating activities benefited from the sale of tickets to managed corporate customers, including tickets for travel during and beyond the quarter, which grew 14% during the March 2024 quarter compared to the March 2023 quarter, led by large accounts, particularly in the technology, consumer services and financial services sectors. In addition, total cash sales to American Express were $1.7 billion in the March 2024 quarter, an increase of approximately 5% compared to the March 2023 quarter.

Cash flows used in investing activities during the quarter totaled $637 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 $1.4 billion in the March 2024 quarter. Additionally, we had cash outflows of $712 million 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 March 2024 quarter compared to the March 2023 quarter on a 2% increase in capacity and two point increase in 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 March 2024 quarter increased compared to the March 2023 quarter in each geographic region. Passenger unit revenue declined 3% as we continued to invest in rebuilding our Latin and Pacific networks. Strong demand for international travel, particularly to leisure destinations, enabled a one point increase in load factor on a 16% increase in capacity compared to the March 2023 quarter.

Refinery. Refinery sales to third parties increased $269 million compared to the March 2023 quarter due to higher sales volume. 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 March 2023 quarter due to increased co-brand card spend.

Salaries and Related Costs. We implemented a base pay increase for eligible employees of 5% effective April 1, 2023 and on January 1, 2024, Delta pilots received a 5% pay increase. Additionally, we had approximately 5,000 more employees as of March 31, 2024 than at March 31, 2023, principally in in-flight service, flight operations and aircraft maintenance, in order to support our operations. Each of these items contributed to the increase in salaries and related costs during the March 2024 quarter compared to the March 2023 quarter.

Aircraft Fuel and Related Taxes. Aircraft fuel and related taxes decreased $78 million compared to the March 2023 quarter primarily due to a 15% decrease in the market price of jet fuel partially offset by a 5% increase in consumption on a 7% increase in capacity. The refinery also provided a benefit of five cents per gallon compared to a benefit of 25 cents per gallon in the March 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 $269 million compared to the March 2023 quarter due to higher sales volume. 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 March 2023 quarter that contributed to our increased capacity.

Delta Air Lines, Inc. | March 2024 Form 10-Q 19

Item 2. MD&A - Results of Operations

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.

Miscellaneous, net	(56)		(102)		46
Total non-operating expense, net	$	(492)	$	(229)	$	(263)

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 and we have continued to pay down our debt during the three months ended March 31, 2024 with $712 million of payments on debt and finance lease obligations. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities.

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

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

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

Income Taxes

We project our annual effective tax rate for 2024 will be between 23% and 25%. 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.

Delta Air Lines, Inc. | March 2024 Form 10-Q 20

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 generated lower operating income in the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily as a result of lower pricing.

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 March 31, 2024, we had $7.4 billion in cash, cash equivalents, short-term investments and aggregate undrawn principal amount available 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 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 March 31, 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 $2.4 billion and $2.2 billion in the three months ended March 31, 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% and 21% of our total operating expense for the three months ended March 31, 2024 and 2023, respectively. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. The market price for jet fuel was lower in the March quarter 2024 compared to the March quarter 2023. Fuel consumption was higher during the three months ended March 31, 2024 compared to the prior year period due to the increase in capacity. We continue to expect that fuel consumption for the full year 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, where we paid $563 million in profit sharing 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 three months ended March 31, 2024, we accrued $125 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 $1.7 billion in the three months ended March 31, 2024, an increase of 5% 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.

Delta Air Lines, Inc. | March 2024 Form 10-Q 23

Item 2. MD&A - Financial Condition and Liquidity

Investing Activities

Short-Term Investments. During the three months ended March 31, 2024, we redeemed a net of $546 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 $1.2 billion and $1.0 billion for the three months ended March 31, 2024 and 2023, respectively. 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 $93 million was incurred in the three months ended March 31, 2024.

Financing Activities

Debt and Finance Leases. In the three months ended March 31, 2024, we had cash outflows of $712 million related to repayments of our debt and finance lease obligations. 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 March 2024 quarter, the Board of Directors approved a quarterly dividend of $0.10 per share, which we paid on March 18, 2024 for total cash dividends of $64 million.

Covenants. We were in compliance with the covenants in our debt agreements at March 31, 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.

Item 2. MD&A - Supplemental Information

Supplemental Information

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

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

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

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

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

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

•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.

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.
