Japan's top carriers were the most on-time airlines in 2021
Japanese airlines offered up some impressive on-time performance in 2021.
The country's two network carriers were the most on-time airlines in the world this year, according to aviation data provider Cirium.
All Nippon Airways took top billing, with a 95.04% on-time arrival rate and a completion factor of 99.24%, meaning that just 0.76% of all flights were canceled.
Japan Airlines took the number two spot, with an on-time arrival rate of 94.13% and an identical completion factor of 99.24%.
The top U.S. carrier on this list was Delta Air Lines, in the number five spot, which saw 87.80% of its flights arrive on time, with a 99.82% completion factor.

In addition, Delta Air Lines won a special "platinum award" for operational excellence.
"It is the world's best performing airline when considering on-time performance, operational complexity and its ability to limit the impact of flight disruption to its passengers," Cirium writes in its on-time performance review.

Cirium started tracking on-time performance again on June 1, when it saw enough of an uptick in flights globally, a spokesperson explained to TPG. The period for the awards spans from June 1 to Dec. 20 — a few days before airlines globally and especially in the U.S. began to see significant operational disruptions due to the COVID-19 Omicron variant, as well as weather.
