United Pitches Audacious Merger With American, Sending AAL Stock Up 5%

United Airlines Holdings Inc. Chief Executive Officer Scott Kirby has proposed a combination with rival American Airlines Group Inc., a move that would create the world's largest carrier but faces significant antitrust hurdles, sending American's stock up 5% on the news.

"President Trump, he loves to see big deals happen," Transportation Secretary Sean Duffy told CNBC on April 7, adding a caveat that any large airline merger would require carriers to "peel off" assets to maintain competition.

The proposal, first reported by Bloomberg and confirmed by other sources, was pitched to senior government officials. While no formal process is underway, the news caused American Airlines (AAL) shares to jump 5% in after-hours trading on April 13. A combined entity would control over a third of the U.S. domestic market, raising immediate red flags for regulators at both the Department of Justice and the Department of Transportation.

The audacious pitch tests the limits of a business-friendly Trump administration, with any potential approval likely requiring major concessions, such as divesting key hubs where the two carriers overlap significantly, like Chicago’s O’Hare International Airport. For Kirby, a former American Airlines president, the move is also a personal gambit to consolidate an industry grappling with rising fuel costs from the U.S.-Iran conflict.

A Test for Regulators

Kirby’s proposition comes at a time of renewed speculation about airline consolidation. The United CEO has previously expressed interest in a deal with JetBlue, and industry executives have noted that the current political climate may be favorable for mergers. Transportation Secretary Duffy himself stated, "Is there room for some mergers in the aviation industry? Yeah, I think there is."

However, a merger between two of the top three U.S. carriers is on a different scale entirely. Analysts are skeptical, with many viewing the proposal as a strategic maneuver. One theory suggests Kirby is floating an impossibly large deal to make a subsequent, smaller acquisition—like a bid for JetBlue—seem more reasonable to regulators by comparison. "It feels like classic horse trading to me," one commenter on the popular aviation blog One Mile at a Time noted. "Propose merger with AA. Expect hue and cry, followed by rejection. Propose JetBlue merger. Crickets, then approval."

Personal and Professional Rivalry

The history between the two airlines, and Kirby himself, adds another layer to the proposal. Kirby served as president of American Airlines before leaving for United in 2016 after it became clear he would not get the top job. Since becoming CEO of United, he has been a vocal critic of American's strategy, recently stating the airline was "cooked" due to its failure to invest in premium products.

This long-standing rivalry has played out in competitive arenas like Chicago O'Hare, where the two airlines have battled for market share. A merger would end that rivalry, creating a dominant carrier at several major U.S. hubs and potentially reducing consumer choice and increasing fares, the primary concerns for antitrust regulators. The deal would also consolidate operations against their main remaining rival, Delta Air Lines Inc.

For now, the proposal remains informal. Both United and American Airlines have declined to comment on the reports. The next move will depend on the reception from the administration and the reaction from shareholders, who have already signaled initial approval through the 5% bump in American's stock price.
