United Airlines CEO Scott Kirby had been weighing the possibility of a major airline combination for months before the idea surfaced publicly, and earlier this year, he raised the concept directly with the Trump administration. Kirby discussed a potential tie-up with American Airlines during a White House meeting in late February, after having considered such a move since at least last fall.
The idea would amount to one of the biggest merger proposals ever contemplated in U.S. aviation. A combination of United and American would create the world’s largest airline and further reshape an industry already heavily consolidated, with United, American, Delta, and Southwest together controlling about 80% of the domestic market. That scale is precisely why many analysts believe any serious attempt would face extreme regulatory resistance.
Kirby has argued publicly that larger U.S. carriers need more size to compete internationally, especially on long-haul routes where foreign airlines remain strong. In a January interview, he said greater scale would help U.S. airlines retain customers who often choose overseas carriers for flights to regions such as the Middle East. That view helps explain why merger logic, from his perspective, is tied not just to domestic power but to global competition.
Still, the obstacles are formidable. Analysts and antitrust experts have warned that a deal of this magnitude would likely trigger intense scrutiny because of overlapping routes, concentration in major hubs, and the broader risk of higher fares and weaker competition for consumers. Neither United nor American has confirmed any merger talks.
The episode nevertheless offers a revealing glimpse into where the industry’s largest players may be looking next. After years of domestic consolidation, the next strategic debate may not be about survival but about whether more scale is the only path left for U.S. airlines hoping to strengthen their position on the global stage.
