American Airlines has publicly accused rival United Airlines of reckless overscheduling at Chicago O’Hare International Airport, claiming the strategy is driving the busy hub towards severe operational chaos this summer. In an internal memo sent to Chicago based employees earlier this month and later reported widely, American’s chief operating officer David Seymour and chief commercial officer Nathaniel Pieper described United’s approach as a ploy to overschedule the airport to manipulate gate allocation rules without regard for customers, team members or partners. They warned that without intervention United’s actions would lead to long taxi times, extensive tarmac delays, missed customer connections, disrupted crew sequences and cascading disruptions across the system.
The dispute stems from intense competition between the two carriers which dominate operations at O’Hare, the United States’ busiest airport by takeoffs and landings in recent years. Both have announced expansion plans for the 2026 summer season starting late March, but published schedules now exceed the airport’s practical capacity with over 3,000 daily operations projected on peak days. The Federal Aviation Administration has intervened by convening airlines for a scheduling reduction meeting and proposing to cap daily operations at around two thousand eight hundred to prevent severe congestion, flight delays and cancellations.
This would require approximately 10pc cuts to flights during the IATA summer period running until late October.
American Airlines has welcomed the FAA’s move and placed primary blame on United for intentionally exceeding maximum departure rates in efforts to secure more gates and market share. The carrier argues that United’s aggressive addition of flights particularly in peak waves risks repeating gridlock seen at other congested hubs like Newark last year.
While United has not issued a direct public rebuttal in recent reports, the ongoing turf war includes related issues such as gate reshuffles at the airport where American has pursued legal action against the city over allocations.
As negotiations continue between the FAA, airlines and Chicago’s aviation authorities the situation underscores the challenges of balancing growth ambitions with infrastructure limits at major US hubs. Travellers heading through O’Hare this summer may face schedule adjustments as carriers work to comply with any imposed caps though the exact reductions remain under discussion.
