Delta Most On-Time Airline, Air Canada Least: 2023 Report

These days, air travel can feel more chaotic than ever before, between exorbitant prices, lengthy waits, unruly passengers, and more.

Sometimes, people can regain control of their airport experience with travel hacks, like bringing a collapsible water bottle to save on expensive purchases and veering right at TSA when most passengers go left.

But, generally speaking, the on-time arrival and departure of the aircraft itself is completely out of their hands — left up to the airport or carrier to navigate.

And it’s not always smooth: In July 2023, ticket-selling airlines reported an on-time arrival rate of 69.6%, decreasing from both the rate of 71.3% in June 2023 and the rate of 74.9% in July 2022, per the Bureau of Transportation.

But which ones do the best job? Aviation analytics firm Cirium examined more than 600 real-time information sources spanning airlines, airports, global distribution systems, civil aviation authorities, and more to find out.

Cirium defines an “on-time” flight as one that arrives within 15 minutes of the scheduled gate arrival and an “on-time” departure as one that leaves within 15 minutes of the scheduled takeoff.

According to the report, Delta clinched the top spot for the most on-time airline in North America and took the Cirium Platinum Award, which honors a “commitment to operational performance and minimizing passenger disruption,” for the third year in a row.
