The Federal Aviation Administration (FAA) will impose a daily flight limit at Chicago O’Hare International Airport this summer. This measure forces airlines to scale back their schedules following a surge in planned operations that threatened to saturate the airport and trigger massive delays.
Operational Restrictions for the Summer Season
Under an order issued this Thursday, the FAA will restrict operations at O’Hare to a maximum of 2,708 daily arrivals and departures. This limitation will be in effect from May 17 through October 24. According to the agency, this operational ceiling is essential to prevent punctuality from deteriorating further than the performance levels seen last summer.
The decision comes after weeks of tense negotiations with carriers. Airlines had scheduled more than 3,000 daily flights for peak demand days—an increase of nearly 15% compared to the previous year—despite ongoing construction and operational constraints at one of the busiest hubs in the United States.
Impact of Over-scheduling and Ongoing Construction
The FAA noted that last summer’s performance highlighted the risks of over-scheduling flights in an environment with physical constraints. Data from the 2025 summer season reflect compromised operations:
- On-time Departures: Only 56% of flights departed on schedule.
- On-time Arrivals: Only 58% of landings met their scheduled time.
- Disruptive Factors: Construction projects and general congestion significantly slowed traffic across the entire airfield.
With this measure, the aviation authority seeks to prioritize system stability over traffic volume.
