Chicago O’Hare handled more takeoffs and landings than any other airport in the world in 2025, taking the top spot for aircraft movements. (aci.aero) Airports Council International World said O’Hare recorded 860,015 aircraft movements in 2025, up 10.8% from 2024. The group’s April 14, 2026 rankings count aircraft movements, not passengers, so each takeoff or landing adds to the total. (aci.aero) The ranking is separate from the passenger race, where Hartsfield-Jackson Atlanta remained No. 1 in 2025 with more than 108 million travelers. O’Hare’s lead was in flight volume, a measure that reflects how intensively an airport’s runways are used. (aci.aero) That distinction has become more important in Chicago as federal officials focus on congestion at O’Hare. On April 16, 2026, the Federal Aviation Administration said O’Hare had fewer than 60% of arrivals and departures on time last summer and announced a summer scheduling reduction to cap daily operations at 2,708. (faa.gov) The Federal Aviation Administration said airlines had planned more than 3,080 flights on peak summer 2026 days, or 14.9% above summer 2025 peak-day levels. The agency said it organized meetings with airlines and the city before ordering the reduction to curb overscheduling during peak hours. (faa.gov; transportation.gov) O’Hare’s return to No. 1 also marks a sharp jump from its 2024 standing. In Airports Council International World’s preview of 2024 rankings, Atlanta led aircraft movements with 796,224 and O’Hare was second with 776,036. (aci.aero) In 2023, O’Hare was already among the world’s busiest airports but on a smaller scale, with more than 720,000 takeoffs and landings, according to Patch’s summary of the earlier Airports Council International data. The 2025 total shows how quickly flight activity has climbed in two years. (patch.com; aci.aero) The new ranking gives O’Hare bragging rights on aircraft volume, but it also lands as Washington is trying to slow the airport down at the busiest times of day. O’Hare is back at No. 1, even as the Federal Aviation Administration says the schedule now has to be trimmed to keep delays from spreading. (aci.aero; faa.gov)
