Asiana Airlines Delay Rate, Cancellations & On-Time Performance OZ

80.3% On-time departure 84.3% On-time arrival

Cancellation: 0% / Avg delay when late: 37min

Last 28 days ・ 1076 flights ・ Includes estimates 198 estimated

Some airlines do not publish gate departure/arrival times.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.
