How long after a delay is a flight plan filed? I was tracking a plane and I don’t think the flight plan was on FA a significant time before takeoff. Flight was delayed about 100 minutes. I checked in on FlightAware at around that time and the old plans were still there.
P.S. FlightAware’s estimated arrival time on this one was freaking ace. Plane touched down about 10 seconds after the minute.
Edit: The actual time is there, but it’s 10 minutes off? Estimated time earlier in the flight was 9:41, changed to 9:51 later on, which might or might have been due to an unusual take-off where they had to make a U-turn rather than the usual straight out. Final time is now 9:41. I know, I know, "At least part of this flight occurs outside of FlightAware’s service area. Information on this page may be unreliable. "
