Cancellation: 0% / Avg delay when late: 34min

Some airlines do not publish gate departure/arrival times. For those flights we estimate the gate times from the takeoff/landing record and the airport's measured taxi times (validated at 3.5 min mean error, 94.4% agreement on the on-time call). Without the estimate, those airlines' flights would drop out of the sample entirely and cross-airline comparison would break.
