COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) | COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company, and its principal, wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United. The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company's financial position and results of operations for interim periods presented. The UAL and United financial statements should be read together with the information included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the "2021 Form 10-K"). The Company's quarterly financial data is subject to seasonal fluctuations. Historically its second and third quarter financial results have reflected higher travel demand, and were better than its first and fourth quarter financial results.
