“American Airlines is not engaged with or interested in any discussions regarding a merger with United Airlines,” the carrier stated officially.

The Dallas-based airline emphasized that such a combination would prove “negative for competition and for consumers,” while running counter to established antitrust regulations.

United’s Chief Executive Scott Kirby had presented the merger concept to the Trump administration during a White House meeting in February. Industry sources indicate he had been exploring the possibility since autumn of last year.

Kirby’s rationale centered on enhanced competitiveness against Middle Eastern carriers that currently dominate regional routes. “If we’re bigger and have more offerings for those customers, possibly it’s more rational for them to fly us,” he explained.

A merged United-American entity would have created the globe’s largest air carrier. The combined operation would control approximately 40% of domestic flight capacity, based on data from aviation analytics firm OAG.

Cornell University law professor George Hay offered a stark assessment of regulatory prospects: “This would be the biggest of all time. I can’t even see the slightest chance that a court would allow it.”

Crude Oil Surge Compounds Industry Challenges

Complicating matters further, oil prices climbed 6% Monday as renewed concerns emerged regarding US-Iran diplomatic efforts. Elevated fuel expenses represent a direct headwind for airline profitability.

Equities for United, Delta, and Southwest all declined more than 2% during premarket activity. Travel sector peers including Royal Caribbean, Norwegian Cruise Line, and Carnival similarly dropped approximately 2%.

The Monday selloff reversed Friday’s gains when these same stocks had advanced following temporary oil price declines after the Strait of Hormuz reopened to shipping traffic.

Operational Disruptions Mount Across Carriers

Widespread flight delays compounded investor concerns. Southwest Airlines experienced delays affecting more than 1,200 flights on Sunday — representing approximately 29% of its daily schedule, according to FlightAware tracking data.

American Airlines delayed 799 flights, accounting for 22% of its operations. Delta and United reported delays impacting 16% and 13% of their respective schedules.

American’s stock has declined 17% year-to-date, though it posted a 19% surge during April as optimism regarding Middle East diplomatic progress increased.

American Airlines equity jumped 8% last Tuesday following initial reports of United’s merger overture, then gained an additional 4% Friday.

American Airlines is scheduled to announce quarterly financial results Thursday. United Airlines and Southwest will also release earnings reports during the current week.

Delta has already demonstrated its capacity to largely offset rising fuel expenditures. Whether competing carriers can replicate this performance remains uncertain.
