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, 2024. 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 nine months ended September 30, 2025 are not necessarily indicative of operating results for the entire year. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes. On July 4, 2025, the One Big Beautiful Bill Act, was signed into law. The legislation did not have a material impact on our income tax expense for the September 2025 quarter, and we do not expect it to materially change our effective income tax rate for 2025. Recent Accounting Standards Standards Effective in Future Years In September 2025, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2025-06, "Targeted Improvements to the Accounting for Internal-Use Software." This standard is intended to improve the operability and application of guidance related to capitalized software development costs and becomes effective January 1, 2028. We are assessing the potential impact this ASU may have on our Consolidated Financial Statements upon adoption.
