Model lowers Kansas City departure delay risk 6–9 AM Saturday to 31%, near normal

\n

What changed: 41% → 31%; calm-weather level 7%

\n \n

Tailodds’ model gives the 37 departures scheduled from Kansas City 6–9 AM Saturday an average 31% chance of leaving 15+ minutes late. With calm weather the same flights would average 7%. From the 10:00 PM CST forecast (model famB-sd-v4i). This is a forecast, not a report of delays.

Kansas City: 8 of 15 departures in the next 90 min have their aircraft due in with under 35 min to turn

\n \n \n

Of the 22 departures scheduled from Kansas City (MCI) between 5:38 PM and 7:08 PM CST, FAA flight plans name the aircraft for 15. For 8 of those, the aircraft’s previous flight into MCI 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.
