American Airlines (AA, Dallas/Fort Worth) has issued a statement denying any engagement with or any interest in discussions regarding a merger with United Airlines, after the latter’s chief executive, Scott Kirby, reportedly raised the possibility of a combination between the two companies, fuelling rumours about further consolidation in the United States.

“While changes in the broader airline marketplace may be necessary, a combination with United would be negative for competition and for consumers, and therefore inconsistent with our understanding of the Administration’s philosophy toward the industry and principles of antitrust law,” American Airlines said.

A merger between the two carriers would create the largest airline in the world, with a combined fleet of over 2,000 aircraft and close to 40% of US domestic capacity. According to ch-aviation data, American Airlines operates an in-house fleet of 1,025 aircraft and fully owns three regional carriers (Envoy Air, Piedmont Airlines, PSA Airlines), while United’s fleet totals 1,097 aircraft.

American said its focus would remain the execution of its strategic objectives and positioning itself to succeed for the long term, collaborating with the US government to “strengthen the broader airline industry.”

Earlier in April 2026, US transportation secretary Sean Duffy said he believed there was room for consolidation in the US airline industry and that while he would not pre-commit to anything, President Donald Trump “loves to see big deals happen.” Duffy elaborated that any potential merger would have to be assessed on a case-by-case basis and that for any combination of larger airlines, “they’re going to have to peel off some of their assets.”
