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.

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

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

Basis for Review Results

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

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, 2022.

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

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

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

NOTE 2. REVENUE RECOGNITION

Passenger Revenue



	Three Months Ended June 30,				Six Months Ended June 30,
(in millions)	2023		2022		2023		2022
Ticket	$	11,829	$	9,773	$	21,068	$	15,759
Loyalty travel awards	902		744		1,645		1,287
Travel-related services	474		441		903		819
Passenger revenue	$	13,205	$	10,958	$	23,616	$	17,865

Ticket

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

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

Loyalty Travel Awards

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

Delta Air Lines, Inc. | June 2023 Form 10-Q 7

Notes to the Consolidated Financial Statements

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

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

Miles redeemed for non-air travel and other	(80)		(73)
Balance at June 30	$	8,267	$	7,757

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.

Notes to the 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:

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

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

As of June 30, 2023, the estimated fair value of our short-term investments was $3.4 billion. Of these investments, $3.1 billion are expected to mature in one year or less, with the remainder maturing by the first quarter of 2025. Investments with maturities beyond one year when purchased are classified as short-term investments if they are expected to be available to support our short-term liquidity needs.

Long-Term Investments. Our long-term investments 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 primarily related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). Our fuel hedge portfolio may consist of a combination of options, swaps or futures contracts, most of which have a duration of less than three months. Option and swap contracts are valued under income approaches using option pricing models and discounted cash flow models, respectively, based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices. We recognized gains of $12 million and $43 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 and six months ended June 30, 2023, respectively, compared to losses of $239 million and $478 million for the three and six months ended June 30, 2022, respectively. The gains recognized during the first six months of 2023 were composed of $39 million of mark-to-market gains and $4 million of settlement gains 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.

NOTE 4. INVESTMENTS

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

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

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

Availability Under Revolving Credit Facilities

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

Early Settlement of Outstanding Notes

During the six months ended June 30, 2023, we repurchased a principal amount of $1.1 billion of various secured and unsecured notes and a portion of the SkyMiles Term Loan on the open market and made early principal repayments of $585 million on various notes secured by aircraft. These payments resulted in a $50 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.

(1)The timing of these commitments is based on our contractual agreements with the aircraft manufacturers and may be subject to change based on modifications to those agreements or changes in delivery schedules.

Our future aircraft purchase commitments included the following aircraft at June 30, 2023:


Aircraft purchase commitments by fleet type
Aircraft Type			Purchase Commitments
A220-300			70
A321-200neo			120
A330-900neo			17
A350-900			16
B-737-10			100
Total			323

Aircraft Orders

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

Legal Contingencies

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

Employees Under Collective Bargaining Agreements

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

NOTE 9. SEGMENTS

Refinery Operations

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

Segment Reporting

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

Fair Value Obligations

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

NOTE 10. EARNINGS/(LOSS) 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 2022 Form 10-K.

June 2023 Quarter Financial Highlights

Our operating income for the June 2023 quarter improved $972 million compared to the June 2022 quarter to $2.5 billion for the reasons discussed below.

Revenue. Compared to the June 2022 quarter, our total revenue increased $1.8 billion, or 13%, due primarily to strength in the demand for travel and a 17% increase in capacity. Total revenue, adjusted (a non-GAAP financial measure) to exclude refinery sales to third parties, increased in the June 2023 quarter by $2.3 billion, or 19%, compared to the June 2022 quarter.

Operating Expense. Total operating expense in the June 2023 quarter increased $782 million, or 6%, compared to the June 2022 quarter, primarily due to the impact of higher capacity as well as higher employee costs from increased wages and profit sharing, partially offset by lower fuel expense. Total operating expense, adjusted (a non-GAAP financial measure) in the June 2023 quarter increased $1.3 billion, or 12%, compared to the June 2022 quarter. Adjustments were primarily to exclude expenses related to refinery sales to third parties.

Our total operating cost per available seat mile ("CASM") decreased 9% compared to the June 2022 quarter, primarily due to decreased fuel expense and expenses related to refinery sales to third parties on a 17% increase in capacity. Non-fuel unit costs ("CASM-Ex", a non-GAAP financial measure) increased 2.4%.

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, 2023 was $8.8 billion. During the June 2023 quarter, operating activities generated $2.6 billion. Also, during the quarter, cash flows used in investing activities were a net of $1.4 billion, primarily for capital expenditures. These operating and investing activities generated $1.1 billion of free cash flow (a non-GAAP financial measure) in the June 2023 quarter. Additionally, we had cash outflows of approximately $1.8 billion related to repayments of our debt and finance leases.

Total cash sales to American Express were $1.7 billion in the June 2023 quarter, an increase of approximately 22% compared to the June 2022 quarter.

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

(1)Total amounts in the table above may not calculate exactly due to rounding.

(2)TRASM, adjusted is a non-GAAP financial measure. For additional information on adjustments to TRASM, see "Supplemental Information" below.

Compared to the June 2022 quarter, our total revenue increased $1.8 billion, or 13%, due primarily to strength in travel demand on a 17% increase in capacity, with growth in revenue from premium products outpacing main cabin. This increase was partially offset by a decline in third-party refinery sales recorded in other revenue. See "Refinery Segment" below for additional details on the refinery's operations, including third party refinery sales. The increase in total revenue, in conjunction with a larger increase in capacity, resulted in a 4% decrease in total revenue per available seat mile ("TRASM").

Domestic

Domestic passenger revenue increased 8% in the June 2023 quarter compared to the June 2022 quarter on a 9% increase in capacity and a slight decrease in load factor, with domestic business travel revenue improving compared to the June 2022 quarter.

International

International passenger revenue for the June 2023 quarter increased compared to the June 2022 quarter in each geographic region. In June 2022, the United States lifted its COVID-19 testing requirement for international travel, which has had a positive impact on international demand. In addition, other countries in our network have removed travel restrictions since that time, resulting in revenue improvement across all international regions.

U.S. consumers continue to show a strong desire for trans-Atlantic travel, driving up revenue during the June 2023 quarter on 35% capacity growth. This demand for travel has been led by leisure destinations in southern Europe and premium product load factor.

Delta Air Lines, Inc. | June 2023 Form 10-Q 20

Item 2. MD&A - Results of Operations

Latin America region revenue increased during the June 2023 quarter, due to strong demand for leisure destinations in South America and the Caribbean, in addition to continuing the implementation of our joint venture with LATAM.

Pacific region revenue benefited from improved demand for travel to the region, particularly to Japan, on increased capacity following the easing of travel restrictions and the performance of our joint venture with Korean Air.

Loyalty program revenue relates to brand usage by third parties and other performance obligations embedded in miles sold, including 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 2022 quarter, due to continued strength in co-brand card spend and card acquisitions.

Miscellaneous. Miscellaneous is primarily composed of revenues related to Delta Sky Club lounge access, including access provided to certain American Express cardholders, and codeshare agreements. The volume of these transactions has increased compared to the June 2022 quarter in line with the increased capacity.

(1)Certain variances are labeled as not meaningful ("NM") throughout management's discussion and analysis.

Salaries and Related Costs. 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%.

Over the past year, we implemented base pay increases for eligible employees of 5% effective April 1, 2023 and 4% effective May 1, 2022. Additionally, we have approximately 9,000 more employees as of June 30, 2023 than at June 30, 2022, principally in in-flight service, flight operations and aircraft maintenance, in order to support the growth in our operations. Each of these items contributed to the increase in salaries and related costs during the June 2023 quarter compared to the June 2022 quarter.

Aircraft Fuel and Related Taxes. Fuel expense decreased $707 million compared to the June 2022 quarter primarily due to a 38% decrease in the market price of jet fuel partially offset by a 16% increase in consumption on a 17% increase in capacity. We expect jet fuel prices to remain volatile throughout 2023.

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 decreased $549 million compared to the June 2022 quarter due to lower pricing.

Contracted Services. During the June 2023 quarter, demand and capacity increased compared to the June 2022 quarter due to the ongoing recovery of our operations. The continued restoration of our operations and associated higher volume-related expenses and inflationary pressures were the primary drivers for the increase in contracted services.

Delta Air Lines, Inc. | June 2023 Form 10-Q 22

Item 2. MD&A - Results of Operations

Aircraft Maintenance Materials and Outside Repairs. Maintenance expense increased compared to the June 2022 quarter as we continued to restore our operations and to support our operational reliability.

Passenger Commissions and Other Selling Expenses. Compared to the June 2022 quarter, passenger revenue increased in the June 2023 quarter which was the primary reason for the increase in passenger commissions and other selling expenses.

Passenger Service. Passenger service expenses increased compared to the June 2022 quarter due to higher volume-related expenses associated with increased demand and inflationary pressures.

Profit Sharing. Profit sharing increased by $541 million compared to the June 2022 quarter due to higher projected profitability in 2023. Our profit sharing program pays 10% to all eligible employees for the first $2.5 billion of annual pre-tax profit and 20% of annual pre-tax profit above $2.5 billion, as defined by the terms of the program. In determining the amount of profit sharing, the program defines profit as pre-tax profit adjusted for profit sharing and certain other items.

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

Total non-operating expense, net	$	(174)	$	(486)	$	312	$	(403)	$	(902)	$	499

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

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 companies without publicly-traded shares. See Note 4 of the Notes to the Condensed Consolidated Financial Statements for additional information on our equity investments measured at fair value on a recurring basis.

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

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

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

Income Taxes

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

Refinery Segment

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

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

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

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

As of June 30, 2023 we had no net fair value obligation outstanding. Our obligation is calculated using the Renewable Fuel Standard ("RFS") volume requirements, which were finalized in 2022 for the 2021 and 2022 obligations, and proposed in 2022 for 2023 obligations. In the March 2023 quarter, we settled a portion of our 2021 RINs obligation with the EPA. We expect to settle the remaining 2021 and our entire 2022 RINs obligation by the 2022 compliance deadline in the December 2023 quarter.

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

Item 2. MD&A - Financial Condition and Liquidity

Financial Condition and Liquidity

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

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

Sources and Uses of Liquidity

Operating Activities

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

Our operating cash flow is impacted by the following factors:

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

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

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

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

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

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

Item 2. MD&A - Financial Condition and Liquidity

Investing Activities

Short-Term Investments. During the six months ended June 30, 2023, we purchased a net of $50 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 $2.5 billion and $2.7 billion for the six months ended June 30, 2023 and 2022, respectively. Our capital expenditures are primarily related to the purchases of aircraft, airport construction projects, fleet modifications and technology enhancements.

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

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

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

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

Financing Activities

Debt and Finance Leases. In the six months ended June 30, 2023, we had cash outflows of $3.0 billion related to repayments of our debt and finance lease obligations, including $1.1 billion of principal amounts for the early repurchase of various secured and unsecured notes and a portion of the SkyMiles Term Loan on the open market and early principal repayments of $585 million on various notes secured by aircraft. Approximately $1.4 billion of the early repurchases and repayments were scheduled to mature after 2023. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities. In the March 2023 quarter, both Fitch and S&P credit rating agencies upgraded the debt rating outlooks for Delta to stable and positive, respectively.

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

Capital Return to Shareholders. On June 15, 2023, the Board of Directors approved and we will pay a quarterly dividend of $0.10 per share on August 7, 2023 to shareholders of record as of July 17, 2023.

Covenants. We were in compliance with the covenants in our debt agreements at June 30, 2023.

Critical Accounting Estimates

Item 2. MD&A - Supplemental Information

Supplemental Information

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

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

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

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

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

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

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

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

Item 2. MD&A - Supplemental Information

Free Cash Flow

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

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

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

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