United Airlines quietly approached Delta Air Lines about a potential merger last year, an extraordinary proposal that would have combined the nation’s two most profitable carriers before talks ended, according to an exclusive report by The Wall Street Journal published July 26.
The merger exploration remained largely confidential until now, with neither airline publicly disclosing the discussions. United CEO Scott Kirby had been considering consolidation ideas since fall 2025, months before he later approached American Airlines in April 2026 with a similar proposal—which American promptly rejected.
Delta and United have emerged as the two dominant carriers in U.S. aviation, separating themselves from competitors through premium-focused strategies and superior profitability. In 2025, United and Delta together accounted for the bulk of industry profits, with both carriers significantly outpacing American Airlines in earnings and market value.
A successful combination would have reshaped the U.S. airline landscape. The two carriers control major hubs across the country—United operates significant operations in San Francisco, Houston, and Washington, while Delta dominates Atlanta and other key markets. Such a merger would have faced substantial regulatory hurdles, requiring approval from the Department of Justice and the Department of Transportation.
The last major airline consolidation that secured regulatory approval was the Delta-Northwest merger in 2008. The Department of Justice approved that deal in October 2008 after a six-month investigation, concluding that consumers would benefit from improved service through the combined carriers’ networks. The merger was completed on December 31, 2009. However, analysts note that the current competitive environment and regulatory scrutiny have grown more stringent since then.
Why the United-Delta talks ended remains unclear. Delta’s leadership has publicly stated the airline is “successful on our own” and has shown no interest in merger discussions. In April 2026, when consolidation rumors swirled around the industry, Delta’s chief commercial officer Joe Esposito said the airline was not involved in any consolidation talks involving United and American.
The revelation comes as the airline industry continues to grapple with consolidation pressures. U.S. Transportation Secretary Sean Duffy and the CEOs of United and Delta have indicated they see room for more airline consolidation, though regulatory approval remains a significant barrier. Kirby’s subsequent approach to American Airlines demonstrated his continued interest in industry consolidation, even after the Delta talks did not advance.
