Iberia and Japan Airlines ranked the highest among global airlines in on-time performance for January 2015 with Asia-Pacific carriers accounting for nearly half of the carriers in the top 20 and taking many of the top spots.

The top 20 airlines include nine Asia-Pacific carriers, eight European carriers, two Latin American carriers and one U.S. carrier (Delta Air Lines) based on statistics for last month from air travel consulting firm FlightStats. Iberia, which topped the ranking, had an average delay time of 37.59 minutes (92.72% of flights on-time), one of the shortest average delays while JAL’s was 38.59 minutes (86.54% of flights on-time).

Emirates, despite all the praise it gets for its in-flight experience, had the longest average delay time (159.23 minutes) for all 49 airlines tracked and only 66.15% of its flights arrived on- time.

Amongst the top 20, KLM had the longest average delay time (73.86 minutes) and 81.28% of its flights arrived on-time. Korean Air had the shortest average delay time (31.29 minutes) even though it’s at the bottom of the top 20 list.

American Airlines, United Airlines, U.S. Airways and Air Canada were the only other North American carriers who made the list. When only looking at the top 10 ranking for on-time performance for North American carriers, what’s notable is that Alaska Airlines ranked second, usually ranking at the top for U.S. airlines. Last month Alaska fell behind Delta Air Lines at number one and in front of Virgin America.
