NOTES: Late departures are flights departing 15 minutes or more after the scheduled departure time. Late arrivals are flights arriving 15 minutes or more after the scheduled arrival time. Late departures and arrivals are strongly seasonal and are affected by weather in winter and summer months and by heavy demand in summer. Cancellations are flights that were not operated but were listed in a carrier's computer reservation system within 7 calendar days of the scheduled departure. Diversions are flights that left from the scheduled departure airport but flew to a nondestination point. Diverted flights may or may not ultimately reach their scheduled destination point.
