Flights on Atlanta-based Delta and its Delta Connection regional carrier partners arrived within 15 minutes of the scheduled time 88.2% of the time, according to the U.S. Bureau of Transportation Statistics.
Delta Air Lines had the second-highest on-time arrival rate among U.S. airlines in 2021, according to new federal data.
That put Delta behind only Hawaiian Airlines, a smaller carrier less often affected by snowstorms, which had a 90.1% on-time arrival rate.
Delta and some other carriers ended the year on a sour note, with mass cancellations during the busy late December holiday travel season due to staffing shortages related to the surge in the omicron variant and bad weather.
It canceled hundreds of flights on some days, leading to a cancellation rate of about 2.5% for the month. That’s far higher than its full-year cancellation rate of less than 0.6%.
Overall, airlines canceled about 2.4% of their December flights. Southwest Airlines, the second-largest carrier at Hartsfield-Jackson International Airport, had the lowest December flight cancellation rate at 1.1%.ExploreAnnual flight counts plummet, but complaints skyrocket
