OAG, a data platform for the worldwide travel industry, recently released their collected information on airline arrival times, ranking airlines in order of most on-time to least.

A flight is considered on-time if it arrives within 15 minutes of its scheduled arrival. OAG collected data from the airlines for its rankings, per The Washington Post.

Delta Air Lines was considered to be the most punctual, arriving on time 83.21% of the time, according to OAG.

The on-time performance was notable amid a challenging year for airlines. The year began with a Federal Aviation Administration system outage in January, resulting in the first nationwide air traffic halt since the Sept. 11, 2001, attacks, per The Washington Post.

Airlines also contended with a shortage of air traffic controllers, prompting schedule adjustments. Additionally, severe weather disrupted flights in New York and other locations during the summer.
