"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.
