Chicago O'Hare International Airport is seeing limited delays Tuesday morning, Aug. 11, after severe thunderstorms triggered major disruptions across Chicago earlier in the week. Travelers should still check directly with their airline because the FAA notes that its airport status information is general and not flight-specific. United recorded 52 cancellations and 1,055 delays Sunday, while American Airlines recorded 10 cancellations and 1,053 delays, according to the same FlightAware-based figures. Latest O'Hare Flight Numbers TuesdayChicago's official airport delay page, which uses OAG data, shows that O'Hare has handled 1,281 arrivals and 1,269 departures over the past 24 hours. Checking the airline's flight status immediately before departure remains more useful than relying on Sunday's disruption totals.
