  1. Initial Observed

    O'Hare: 17 of 56 departures in the next 90 min have their aircraft due in with under 35 min to turn

    Of the 98 departures scheduled from O'Hare (ORD) between 8:27 PM and 9:57 PM CDT, FAA flight plans name the aircraft for 56. For 17 of those, the aircraft’s previous flight into ORD is due at the gate less than 35 minutes before the scheduled departure, or after it (FAA arrival times or estimates plus the airport’s typical taxi time); 1 of those inbound flights have not taken off yet. Measured by Tailodds from FAA flight data; it does not mean each of these departures will leave late.
