Scott Kirby had been weighing a big airline tie-up since last autumn. He then raised the idea with the Trump administration in February.

Where the idea began

Scott Kirby, chief executive of United Airlines, had been considering a potential merger with a rival carrier since last fall, company comments and public remarks show. Timing matters — Kirby talked about scale and global reach on a January podcast, and a few weeks later he raised merger ideas in Washington.

Kirby appeared alongside U.S. Vice President JD Vance and Transportation Secretary Sean Duffy in a White House setting in late October 2025. A photo shows him outside the White House on Oct. 30, 2025; the provided source does not confirm the image captured officials shifting from industry topics to merger talks.

How he described the argument for size

On the Stratechery podcast that aired in January, Kirby argued that bigger carriers can offer customers more options on long-haul routes — and that could persuade frequent domestic flyers to stick with U.S. Carriers when travelling to the Middle East. "Size would help," Kirby said, adding that with more offerings, it might make "more rational" for customers to choose United on certain overseas trips.

That pitch rests on more than marketing: U.S. carriers have argued they lack the global reach of some Gulf airlines. U.S. Carriers have long said they struggle to match the network reach of some Gulf carriers, which they've criticised for receiving government support. Yet the industry has moved beyond blanket complaints: United now has a commercial partnership with Emirates, American Airlines has tied up with Qatar Airways, and Delta struck a strategic deal with Riyadh Air in 2024.

What raising the idea in Washington means

Kirby reportedly discussed a merger with American Airlines while talking to officials in the Trump administration in February. Federal regulators would be a central obstacle to any deal of that scale, because a union of two of the largest U.S. Carriers would reshape domestic competition and network structures.

American, United, Delta and Southwest collectively control about 80% of the domestic market now. A merger between United and American would create the world's largest airline by many measures — seats, fleet and route count — and trigger intense regulatory scrutiny from competition authorities.

Regulatory and political headwinds

Any attempt to combine United and American would face a number of formal and informal hurdles. Antitrust enforcers in the United States examine not just market concentration but also potential harm to consumers: fares, choice and service levels. They also look at how route networks would be altered, and whether smaller rivals would be squeezed out.

Mastheads

There’s also a clear political angle to weigh, because any deal would need approval from regulators and elected officials. Bringing the idea before senior administration officials in Washington suggests the company was testing how the proposal might be received at the highest levels — not uncommon for deals that would require navigation of regulatory and national-interest concerns. JD Vance, U.S. Vice President, and Sean Duffy, U.S. Transportation Secretary, were visible interlocutors in the administration at the time Kirby raised the topic.

Industry consolidation: the long arc

Consolidation in U.S. Aviation isn't new. Over the past two decades carriers have merged and restructured, leaving a market dominated by a few big players. That history matters because antitrust authorities often review past mergers, competitive dynamics and market outcomes when judging a new combination.

Still, no merger on the scale of United plus American has been attempted in the U.S. The last major waves of consolidation left a concentrated market but avoided combining the two carriers that would together command the largest share. That precedent doesn't mean a merger would be blocked automatically, but it does set a high bar.

Global competition and partnership strategies

Honestly, u.S. Carriers have pursued different routes to compete with large Gulf and Asian network carriers. Alliances and bilateral partnerships have been a popular strategy — a way to offer broader global connections without merging balance sheets and fleets.

United's partnership with Emirates, American's cooperation with Qatar Airways, and Delta's strategic agreement with Riyadh Air in 2024 show that U.S. Airlines are increasingly willing to work alongside foreign carriers rather than confront them directly. That trend makes the merger argument: if partnerships can extend networks, do firms need consolidation to achieve the same effects?

Business logic vs legal reality

From a business standpoint, bigger airlines can sync schedules, cut duplicated services and add nonstop flights — all of which can lower costs. They can also negotiate more favourable terms with suppliers and airports because of greater volume.

But legal reality is blunt. Regulators focus on consumer outcomes. If the combined entity were to reduce choices on key city pairs or push up prices, enforcement agencies would likely intervene. The Justice Department and other competition bodies across the globe have shown they will challenge deals that risk harming consumers, even when companies argue national competitiveness is at stake.

Market reaction and next steps

Analysts have been sceptical that a United–American tie-up would clear regulatory review. Many say the complexity and political cost would be too high. Still, the fact that the idea moved from internal consideration last autumn to a conversation with White House officials in February shows United's leadership was at least exploring options.

Exploring options doesn't mean a deal is coming — companies routinely test ideas with regulators to see how they'd be received. Corporate strategy teams often vet bold ideas to map potential paths and pushback. Raising the subject in Washington could be a way to assess political appetite and regulatory temperature — information that helps companies decide whether to proceed.

What it could mean for passengers

If regulators allowed a major consolidation, passengers might see a mix of effects. Some routes could gain more nonstop options; others might be cut to reduce duplication. Airport operations could change as slots and gates are reallocated. Fares might move in either direction depending on competitive responses and capacity adjustments.

But any such changes would be dependent on regulatory remedies or forced divestitures — if regulators approved a deal subject to conditions, those conditions would shape the passenger experience profoundly.
