Delta Air Lines and American Airlines were the two North American carriers with the best on-time performance for January 2022—a month beleaguered by flight delays and cancellations—according to Cirium’s monthly report. Just two-tenths of a percentage point separated the two, with Delta’s on-time performance at 85.3 percent and American’s at 85.1 percent. Globally, the carriers ranked fifth and sixth.

Cirium for North America reviewed carriers that are in the top 20 percent in terms of flight frequency, total seats and available seat kilometers. A flight is considered on time if the aircraft arrives at the gate within 15 minutes of the scheduled arrival time.
