OAG, which dubs itself an “air travel intelligence company,” has released its top-10 rankings of the most and least punctual airlines in 2016. The group analyzed 54 million flight records using full-year data from 2016 to compile the list, and for the purposes of the study defined “on-time” as “a flight that arrives or departs within 14 minutes and 59 seconds (under 15 minutes) of its scheduled arrival/departure time.”
