Among Swoopr's S&P 500 Equal Weight companies, 7 others share that classification; by latest reported revenue, United Airlines Holdings ranks 2 of 8. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes. ## How Does United Airlines Holdings Compare With Its Peers? | Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin | | --- | --- | --- | --- | --- | | [Delta Air Lines (DAL)](https://www.getswoopr.com/stocks/companies/delta-air-lines/) | $63.4 billion FY2025 | 2.8% | 9.2% | 7.9% | | **United Airlines Holdings (UAL)** | $59.1 billion FY2025 | 3.5% | 8.0% | 5.7% | | [American Airlines Group (AAL)](https://www.getswoopr.com/stocks/companies/american-airlines/) | $54.6 billion FY2025 | 0.8% | 2.7% | 0.2% | | [Southwest Airlines (LUV)](https://www.getswoopr.com/stocks/companies/southwest-airlines/) | $28.1 billion FY2025 | 2.1% | 1.5% | 1.6% | | [Alaska Air Group Inc.

Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars. | Measure | United Airlines Holdings | Median of filers | Rank | | --- | --- | --- | --- | | Revenue | $59.1 billion | $28.1 billion | 2 of 7 | | Revenue growth | 3.5% | 2.8% | 3 of 7 | | Operating margin | 8.0% | 2.7% | 3 of 7 | | Net margin | 5.7% | 1.6% | 2 of 7 | A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality. ## Where These Numbers Come From Every figure on this page is a value United Airlines Holdings reported in its own SEC filings, read from the SEC's XBRL data (accession 0000100517-26-000023 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 12, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary. Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation. ## Frequently Asked Questions ### Who are United Airlines Holdings's competitors?
