A testament to Delta’s commitment to punctuality and operational excellence, the airline has earned Cirium's Platinum Award for the third year in a row. This award, which is given to airlines that show exemplary on-time performance while navigating complex operations – all while limiting the impact of disruption to its customers – is made possible by the care and dedication of Delta people.

Overall, Delta delivered industry-leading reliability in the fourth quarter of 2023. Delta’s network system Completion Factor, on-time arrival rate (A0) and on-time departure rate (D0) for the fourth quarter all improved markedly compared to the Q4 2022*. 

In addition to winning the Cirium Platinum Award, Delta topped the rankings for being the most on-time airline in North America. In 2023, Cirium tracked 1,635,486 Delta flights, 84.72% of which arrived on time, which is up from 83.63% the previous year.

Delta's on-time performance far exceeded North American industry benchmarks. Of the more than 8 million flights tracked by Cirium in 2023, 74.45% arrived on time. Delta's on-time arrival percentage was 2.47% higher than its nearest North American competitor.

Additionally, Delta came in above global benchmarks, with 83.67% on-time arrivals across nearly 6 million tracked flights from all global top performers. Cirium defines an on-time flight as one that arrives within 15 minutes of its scheduled gate arrival.
