Prediction from the Amadeus travel network, refreshed daily.
What disrupts ORD
O'Hare is a dual hub for United and American and a perennial top-five delay generator: winter snow, summer convective weather, and sheer traffic density. Its multi-runway modernization helped, but weather days still produce hours-long programs.
Local knowledge: When O'Hare melts down, Midway (Southwest) often keeps moving — worth checking as a rebooking alternative.
