Delta Air Lines prides itself on not canceling flights. Lately, that hasn’t been going so well, reports The Wall Street Journal (May 27, 2026). Its domestic-flight cancellation rate has been higher than the industry average this year, a setback for the airline.
The first weekend in May, Delta canceled hundreds of flights after minor weather disruptions, while other airlines ran relatively smoothly. Only the now-defunct Spirit Airlines scrubbed more. Delta’s cancellations related to pilot availability are more than 10 times historical levels and account for 35% of mainline flight cancellations, up from 7% in 2024.
One issue is that Delta is looking for pilots close to flight departures more often. The often-byzantine process Delta uses to staff those flights hasn’t been functioning well.
For some types of planes, it can take Delta 12 hours to find pilots to work a single trip. Pilots are accepting extra trips less often, with an acceptance rate of 2%, down from 37% a year earlier. Delta’s pilots said they are working more overtime than ever and that the problem is that the airline is chronically short on pilots.
Delta hired 500 pilots in 2025, less than half of what it hired the previous year and hundreds less than the number hired by American and United.
Delta says it is adequately staffed, with 20% more pilots than in 2019. It has accelerated pilot hiring, and boosted crew-tracker and scheduler staffing over 15% since last summer.
Trimming the number of flights Delta is planning to fly, in response to high fuel prices, could help provide more buffer and leave more time for maintenance. Operations leaders are trying to get ahead of looming problems and make quicker decisions about when to cancel flights, before disruptions cascade.
Some fixes to Delta’s pilot-scheduling process are at the center of negotiations between the airline and the pilots union—often a slow-moving process. And it takes time to get newly hired pilots through training and in their seats.

- Why is Delta facing this problem?
When the University of Oregon announced last summer that it was joining the Big Ten conference, it discovered that its team would spend more time this season up in the air than actually playing basketball. Since their season began in November, the Ducks have crisscrossed the country so frequently that the total distance they’ve traveled this season amounts to 26,700 miles, the equivalent of traveling the entire circumference of planet Earth.

The rigid schedule makes sense logistically. Each day, 70 or so trucks from member farms empty milk at the Melrose plant. Converting the unending inflow of milk into 500-pound blocks of cheese requires running the factory 24 hours a day. Divvying the day up into 2 shifts makes it easier for supervisors to ensure sufficient staffing.
