Mineta says O'Hare's on-time performance is "unacceptable" and is causing problems throughout the nation's aviation system. He says US carriers must agree to set schedules that better match the Chicago airport's capacity.
The August 4 meeting will be held at the Federal Aviation Administration's headquarters in Washington.
FAA administrator Marion Blakely says airlines will be asked to reduce their schedules at O'Hare to cut delays.
Blakely says the long-term solution is to add capacity and the FAA will move quickly to evaluate Chicago's proposal to expand O'Hare.
