How to read these numbers
The on-time rate counts the share of flights arriving within 15 minutes of the scheduled gate time, excluding cancellations and diversions — the US DOT standard. A higher rate and lower average delay mean a more reliable schedule. Delays cluster in winter (weather) and peak summer travel; building in a connection buffer of at least 60–90 minutes is sensible on routes below 75% on-time.
