American Airlines shares fell 4% after the carrier publicly rejected the idea of a merger with United Airlines, shutting down talk of a deal that would have created the world's largest airline and reshaped the global aviation market.
"American Airlines is not engaged with or interested in any discussions regarding a merger with United Airlines," the company said in a statement. "While changes in the broader airline marketplace may be necessary, a combination with United would be negative for competition and for consumers."
The firm rejection follows reports that United Airlines CEO Scott Kirby had personally pitched the idea of a combination to senior U.S. government officials, including then-President Donald Trump, in late February. Kirby argued that a consolidated carrier would be a stronger competitor in international markets, according to sources cited by Reuters. A combined United and American would have been the largest airline globally by available capacity, based on 2025 data from OAG.
A deal of this magnitude was always seen as a long shot, facing extraordinary scrutiny from regulators and consumer advocates. American's statement acknowledged this, noting such a deal would be inconsistent with its understanding of the Trump administration's approach to antitrust enforcement. Significant network overlap at major hubs, including Chicago O'Hare and in Texas, would have presented major hurdles to gaining regulatory approval.
The proposal from United came just before a spike in jet fuel prices, which has led airlines to increase fares to offset rising costs. People close to the White House expressed skepticism about a tie-up that could further increase ticket prices for consumers, especially ahead of midterm elections.
United Airlines has declined to comment on the matter.
