Chicago O’Hare International Airport, a bustling hub that has long prided itself on being the nation’s busiest airfield by aircraft operations, is facing a summer of forced restraint. On April 16, 2026, the Federal Aviation Administration (FAA) took the unusual step of capping daily flights at O’Hare for the upcoming summer travel season, a move aimed at cooling a heated competition between United Airlines and American Airlines and averting widespread delays for travelers. The cap, effective from May 17 through October 24, limits daily arrivals and departures to just over 2,700—specifically, 2,708 operations per day—according to the FAA order published Thursday (Chicago Tribune, Reuters).
This intervention comes after both United and American, O’Hare’s two dominant airlines, unveiled plans for significant increases in flights this summer. United, in particular, had announced a bold 34% jump in departures compared to last year, while American planned a more modest 10% increase. Published schedules for peak summer days had soared above 3,080 daily operations, nearly 15% higher than the previous year, even as construction and airfield constraints persisted (Reuters). The FAA, wary of a repeat of last summer’s woes—when only about 56% of departures and 58% of arrivals ran on time due to congestion and construction—stepped in to set a firm limit.
The agency’s order, issued by FAA Administrator Bryan Bedford, is designed to “reduce stress on runways, terminals, and air traffic control systems caused by excessive flight plans,” as reported by the Chicago Tribune. The cap will force airlines to scale back nearly 400 planned operations on peak days, holding activity near last year’s levels and effectively drawing a regulatory line under the airlines’ capacity race at one of the country’s most important hubs.
“If you book a ticket, we want you and your family to have the certainty that you’ll fly without endless delays and cancellations,” said U.S. Transportation Secretary Sean Duffy, emphasizing the importance of reliability for travelers (Reuters).
Both airlines had been vying for market share at O’Hare, with gate space allocated based on previous year’s activity. The FAA’s decision to use the summer 2025 schedules as the baseline for this summer’s cap was not without controversy. United, which gained additional gates in last year’s reallocation, opposed the use of the 2025 baseline and suggested alternatives—such as adjusting each airline’s share of reductions to account for changes in gate allocation. However, Bedford’s order rejected these proposals, stating that using the 2025 baseline “returns to a time when the schedules were not heavily influenced by air carrier attempts to increase market share.”
According to the FAA, United’s planned schedule increases were “the most significant,” and were “accompanied by a campaign of public statements expressing a desire to grow and avoid a scenario in which American Airlines would grow at the ‘expense’ of United” (Chicago Tribune). The agency noted that both airlines’ expansion plans, if unchecked, could have led to “significant Summer 2026 delays due to ongoing construction limiting the airfield’s ability to handle the expected amount of traffic.”
The city’s Department of Aviation, which oversees both O’Hare and Midway airports, initially bristled at the prospect of deeper cuts, describing a proposal to reduce operations to as few as 2,400 per day as “regressive.” But in the end, city officials expressed appreciation for the FAA’s “thoughtful approach” that kept the cap above 2025’s actual numbers and ensured the restrictions would not extend beyond summer 2026. “We are committed to preserving O’Hare’s status as the world’s busiest airport by aircraft operations and the nation’s leading dual-hub airport,” the department said, adding that it and Mayor Brandon Johnson would continue to advocate for strong competition among O’Hare’s hub carriers and for more federal investment in air traffic control staffing (Chicago Tribune).
For the airlines, the cap means tough choices. American Airlines, in a note to employees, estimated that United would need to cut more than 200 takeoffs and landings at peak times this summer, while American would need to cut no more than 40. United, for its part, did not immediately comment on American’s estimate, but said in a statement that it was “reviewing the order and will share additional information, including any next steps, as soon as our review is complete.” United did, however, thank federal officials “for leading the process to find a solution that makes sense for everyone who cares about O’Hare’s success.”
American Airlines voiced its support for the FAA’s move, saying it preserves “sensible competition” and reliability while minimizing disruptions during the busy summer season. “We are pleased to have secured a sufficient level of flights through the FAA’s process to operate a successful hub at O’Hare this summer and satisfy American’s strategic objectives,” the airline stated. American also praised the FAA’s order, saying it would “improve reliability and reduce delays for customers traveling from, to and through O’Hare this summer, and ensure Chicago O’Hare retains its longstanding dual-hub structure.”
The new restrictions are intended as a temporary measure, tied to ongoing construction projects and infrastructure limitations at O’Hare. The FAA has made clear that the cap is set to expire at the end of the summer travel season. However, airlines that breach the cap could face penalties of up to $75,000 per excess flight, a hefty deterrent designed to ensure compliance (Reuters).
According to Reuters, the FAA’s intervention comes as a clear response to the competitive scheduling dynamics between United and American, with the agency rejecting calls to use the more recent 2026 schedules as a baseline. The concern was that allowing airlines to use their 2026 plans as a reference point would only encourage them to file unrealistic schedules in order to gain negotiation leverage—a practice the FAA was keen to avoid.
The backdrop to these regulatory moves is a broader industry rumor: both Reuters and Bloomberg reported that United CEO Scott Kirby had floated the idea of a potential merger with American Airlines during a meeting with President Donald Trump earlier this year. Such a merger, which would create the world’s largest airline, is widely regarded as a long shot by aviation and antitrust experts. Both airlines have declined to comment on the merger speculation, opting instead to focus on the immediate operational challenges at O’Hare.
As the summer travel season approaches, travelers passing through Chicago O’Hare can expect a slightly less crowded sky and, if the FAA’s calculations hold, a more reliable experience. Whether this regulatory pause will lead to lasting changes in how America’s largest airlines compete at their busiest hubs remains to be seen, but for now, the message from Washington is clear: growth must be balanced with reliability, and the flying public’s interests come first.
