United-American Merger Proposal: A Timeline of Events

"This combination... could get regulatory approval." — United CEO Scott Kirby

Overview

United Airlines CEO Scott Kirby proposed a merger with American Airlines, first approaching the Trump administration in early 2025 and later directly engaging American's leadership. American Airlines declined to negotiate, publicly stating the combination would be negative for competition and consumers. President Donald Trump expressed opposition. As of April 27, 2026, Kirby confirmed the proposal is no longer being pursued.

Timeline and Key Discussions

  • Fall 2024: Kirby began considering a potential airline deal, according to people familiar with the matter.
  • February 2025: Bloomberg News and Reuters reported that Kirby raised the idea of a tie-up with American Airlines to the White House during a meeting with then-President Donald Trump.
  • October 30, 2025: Kirby spoke to reporters outside the White House, accompanied by U.S. Vice President JD Vance and Transportation Secretary Sean Duffy.
  • April 2026: Kirby stated he approached American Airlines directly. American Airlines declined to engage and publicly dismissed the proposal.

Statements from Involved Parties

United Airlines CEO Scott Kirby

Kirby argued his vision for the merger differed from previous airline consolidations, which he described as focused on cost-cutting. He claimed the proposed merger aimed at growth, customer investment, and global competitiveness.

Kirby said he was "confident that this combination... could get regulatory approval" but that American Airlines "declined to engage and instead responded by publicly closing the door."

He argued the merger could have:

  • Increased economy seats
  • Expanded international destinations
  • Strengthened competitive profiles against foreign carriers
  • Boosted the U.S. economy through job creation and aircraft manufacturing

Kirby acknowledged that regulatory approval would likely require divestitures in some domestic markets.

American Airlines

"Bad for customers, bad for the industry, and ultimately, that would be bad for American Airlines." — CEO Robert Isom

American Airlines stated it is "not engaged with or interested in" merger discussions. The company said a combination with United would be negative for competition and consumers and would be inconsistent with its understanding of the Trump administration's approach to antitrust enforcement.

U.S. Government

  • President Donald Trump: Told CNBC he does not favor a United-American merger due to competition concerns.
  • Transportation Secretary Sean Duffy: Stated there is "room for some mergers in the aviation industry" but stressed any deal would face close scrutiny and might require airlines to divest some assets.
  • White House: Previously stated it had no opinion on a potential deal.

Regulatory and Political Reactions

"An absolute disaster for the flying public." — Ganesh Sitaraman, Vanderbilt Policy Accelerator

  • Senators Elizabeth Warren and Mike Lee launched a bipartisan probe, citing concerns about reduced competition and higher prices.
  • William McGee, a senior fellow at the American Economic Liberties Project, called the proposal "undoubtedly the most absurd airline merger I’ve ever heard about."

Union Reactions

Dennis Tajer, spokesperson for the Allied Pilots Association (representing American Airlines pilots), stated the union is "always interested in and welcome ideas that will turn around our airline," citing concerns about American's financial and operational performance.

Industry Context

Market Structure

  • According to aviation data group OAG, United and American were the world's two largest airlines by available capacity in 2025, including international flights.
  • A merger would have created the world's largest airline.
  • Industry consolidation over approximately two decades has left American, United, Delta Air Lines, and Southwest Airlines controlling approximately 80% of domestic market share.
  • A combination of this size has not been attempted in the U.S.

Regulatory Challenges

  • Some airline analysts and experts stated that regulatory hurdles would be high for such a combination.
  • A merger would likely face intense antitrust scrutiny from regulators.
  • There is significant overlap between American and United, including operations at Chicago O'Hare and major hubs in Texas.
  • Critics noted potential impacts including overlapping routes, job losses, higher ticket prices, and reduced flight options for consumers.

Market Reaction

  • Following reports of the merger proposal: United shares rose 3.9%, American shares rose 9.3% in early trading.
  • Following the announcement that the proposal was not being pursued: United stock fell 0.8%, American stock fell 1.9%.

International Competition Context

Kirby's Stated Rationale

In a January 2025 podcast, Kirby stated that "size would help" U.S. carriers compete on outbound international flights. He said:

"We have customers that fly United almost all the time or they fly Delta, but when they go to the Middle East, it's fragmented enough that they fly on Emirates. If we're bigger and have more offerings for those customers, possibly, it makes it more rational for them to fly us when they go to the Middle East."

International Carrier Partnerships

U.S. airlines previously raised concerns about government subsidies received by some Middle East carriers. Since then, partnerships have formed:

  • United Airlines has a partnership with Emirates
  • American Airlines has a partnership with Qatar Airways
  • Delta Air Lines signed a strategic partnership with Saudi Arabia's Riyadh Air in 2024

Outcome

Kirby stated that United Airlines will now focus on its independent strategy of "de-commoditizing travel" and investing in technology, product, and infrastructure. As of April 27, 2026, the merger proposal is off the table.
