United CEO Kirby Pushes American Merger Amid Regulatory Opposition

United Airlines CEO Scott Kirby approached the Trump administration in April 2026 about merging with American Airlines. His goal is to forge a U.S. flag carrier by combining United's international network with American's domestic reach and customer base.

Kirby wrote a message outlining his justification for the merger while at the Amangiri luxury resort in Utah that same month. He believes the combined entity would be better positioned to compete with major Asian and Middle Eastern airlines on both product quality and network scale. The proposal was floated during a White House meeting with President Trump.

Regulatory and Political Resistance

The merger concept faces significant antitrust challenges and bipartisan political opposition. American Airlines publicly rejected United's proposal earlier this year. Republican Senator Mike Lee and Democrat Elizabeth Warren later co-signed a letter opposing the merger, citing potential harm to consumers.

Democratic Senator Cory Booker has introduced the CLEAN Mergers Act, which proposes a retrospective review of major Trump-era transactions. Regulators would need to assess whether the merger would substantially lessen competition under Section 7 of the Clayton Act. Kirby himself has stated that the Sherman Act, which was used to block the JetBlue and Spirit merger, is intended to promote competition, not allow massive consolidation.

A potential Democratic administration in January 2029 could revisit the merger, as closing a deal does not prevent future antitrust challenges. Critics argue that eliminating a major competitor like American would reduce competitive pressure on pricing and service industry-wide.

Kirby's Stated Rationale and Market Positioning

Kirby argues that airfares have become too cheap and need to rise for airline profitability, regardless of oil price fluctuations. He has stated that a merger would enable higher margins and the ability to charge more. His vision centers on building a U.S. global juggernaut that could improve overall airline product quality compared to American's current state.

He claims critics are looking at the proposal through a traditional commodity lens and are wrong about its chances for regulatory approval. Kirby has also publicly backed wealth and inheritance taxes and described his past firing from American Airlines as a betrayal. He claims customer feedback, including at his son's soccer games in Dallas, has convinced him of the merger's value for travelers seeking better service.

American's Rejection and Alternative Talks

American Airlines CEO Robert Isom responded to Kirby's texts about the merger, and Kirby was reportedly surprised by American's swift public rejection. American's leadership described talks with Kirby as skeptical but not a definitive no, though they have since hinted at potential alternative discussions with Alaska Airlines.

Kirby has acknowledged that a willing partner is essential for the merger to proceed, making the proposal hypothetical without American's cooperation. The combined airline would control approximately 40% of the U.S. market. Kirby has previously explored a merger with Delta Air Lines in 2025, though those talks ended after a preliminary review.

Despite the hurdles, Kirby remains a persistent advocate for consolidation. He has urged carriers to cancel money-losing flights deemed strategic and defended fees for preferred seats, arguing airline fares must cover operating costs. He lives in Dallas, having never moved since his departure from American over a decade ago, and continues to promote his vision for a transformed U.S. aviation landscape.
