Antitrust doubts on airline merger

A merger between United Airlines and American Airlines is being treated as a long shot because antitrust officials, unions and consumer groups see immediate competition problems. (reuters.com) Reuters reported that United Chief Executive Scott Kirby raised the idea with President Donald Trump in late February, citing two people familiar with the matter. American shares rose 7% in morning trading on April 14, while United shares were up about 2%. (reuters.com) The overlap is the core problem. Reuters reported the combined airline would control more than 50% of seat capacity at 159 airports, and Cornell law professor George Hay told CNBC he could not see “the slightest chance” a court would approve it. (reuters.com) (cnbc.com) The United States airline business is already concentrated. CNBC cited OAG data showing Delta Air Lines, Southwest Airlines, American and United account for about 80% of domestic capacity, and a United-American tie-up would leave the merged carrier with roughly 40% by itself. (cnbc.com) Federal enforcers have spent the last three years arguing that less airline competition means higher fares and fewer choices. In January 2024, the Justice Department said its court win against JetBlue’s planned purchase of Spirit protected travelers from “higher fares and fewer choices.” (justice.gov) American also comes into this story with fresh antitrust baggage. In May 2023, the Justice Department won a case to unwind American’s Northeast Alliance with JetBlue, and the department said the arrangement increased fares and reduced choice in Boston and New York. (justice.gov) That ruling held up on appeal. A First Circuit summary dated November 8, 2024 said the district court found the alliance reduced competition and output without enough pro-competitive benefits. (law.justia.com) Washington has also been formally collecting evidence on airline concentration. In October 2024, the Justice Department and Department of Transportation opened a public inquiry into consolidation, airport access, pricing, rewards programs and the experiences of aviation workers. (transportation.gov) Labor adds another obstacle because airline mergers turn seniority lists, contracts and staffing rules into fights over pay and jobs. United’s flight attendants are in the middle of a 2026 tentative agreement covering 30,000 workers, while American’s largest Transport Workers Union work groups ratified a contract extension for more than 23,000 members in October 2024. (nasdaq.com) (twu.org) Neither airline has laid out a formal deal, and United declined to comment to Reuters on the antitrust implications. For now, the clearest fact is that regulators blocked a smaller airline merger in 2024, and this one would be much bigger. (reuters.com) (justice.gov)
