Mexican airline Aeromexico had the world’s best record for on-time arrivals in 2024, according to new analysis. Delta Air Lines was the top-ranked U.S. carrier. Aviation-data provider Cirium’s annual On-Time Performance Review found 86.

Delta ranked highest among U.S. carriers despite a computer outage​ in July that caused thousands of cancellations.

Across the industry, a flight is considered on time if it arrives less than 15 minutes before its scheduled time.
