Some airlines do not publish gate departure/arrival times.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

Centre line is on schedule. The left end of each line is the departure offset, the dot on the right is the arrival offset — extending right means the delay grew, pulling back left means it was made up in the air. Times are local to each airport.
