United Airlines reportedly initiated discussions with Delta Air Lines last year regarding a potential merger, an effort that would have combined two of the largest carriers in the U.S. aviation market. According to reporting by The Wall Street Journal, United CEO Scott Kirby reached out to Delta CEO Ed Bastian to propose the tie-up.
Sources familiar with the matter indicate that Delta leadership engaged in preliminary due diligence to evaluate the strategic benefits of such a consolidation. However, the discussions did not progress, and both carriers eventually moved on. Neither airline has confirmed the details publicly; a United spokesperson stated the company had ‘nothing to share,’ while Delta declined to comment.
The revelation of these talks highlights United’s broader interest in expansion, though the company’s current strategy appears to favor asset acquisition over large-scale corporate mergers. Beyond the Delta proposal, reports suggest Kirby also explored a potential merger with American Airlines earlier this year. That proposal was reportedly rejected by American CEO Robert Isom, who characterized the potential deal as ‘anticompetitive.’
Industry analysts note that a merger between United and Delta would have faced immense regulatory hurdles. Federal antitrust regulators and state attorneys general typically scrutinize such massive consolidation efforts within the airline industry, citing concerns over reduced competition and potential impacts on ticket pricing and service availability.
Following these unsuccessful attempts, United leadership has signaled a shift in focus. At the International Air Transport Association’s annual meeting in Rio de Janeiro last month, CEO Scott Kirby downplayed the likelihood of a major merger. He emphasized that while United remains interested in purchasing airport slots, gates, and other specific assets, broad consolidation remains a ‘low probability’ for the airline.
