Skymark Airlines Delay Rate, Cancellations & On-Time Performance BC

On-time departure and arrival rates compiled from operational records, covering every flight operated to and from Japan. Switch the period with the tabs below.

Delay rate 16.1% Delay rate is the share of flights departing more than 15 minutes after schedule (100% − on-time departure)

83.9% On-time departure 79.8% On-time arrival

Cancellation: 0.9% / Avg delay when late: 31min

Some airlines do not publish gate departure/arrival times.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