Delta Air Lines canceled 219 flights on Saturday, then 128 on Sunday and 29 on Monday, a run of disruptions that briefly put the carrier far ahead of its biggest rivals in cancellations. By Saturday, the airline had cut 7% of its total flights, while Southwest Airlines, American Airlines and United Airlines each canceled less than 1% of their flights.
The numbers point to a problem that went beyond the weekend weather. An internal memo said pilots’ acceptance of extra flights fell from 37% last year to 2% this year, and said 23.M.7 is now being used 10 to 15 times more than last year. Ryan Gumm said 23.M.7 was never intended for consistent daily operations, underscoring how much more often the airline has been leaning on the process as schedules tighten.
Delta said the recent cancellations were not consistent with its overall reliability in years past, but the scale of the weekend schedule cuts made the airline’s disruption hard to miss. The carrier’s cancellations were more numerous than those of its competitors during the weekend, and other major airlines were under 1% the following day, even as Delta was still dealing with a reduced but persistent level of cancellations on Monday.
The airline had initially pointed to weather issues in Florida, including scattered thundershowers and ground stops, as one reason for the turmoil. But that explanation did not fully match the broader pattern, since the memo linked the trouble to a change in pilot behavior and noted that the airline had also cut in-flight service on hundreds of flights. Taken together, the weekend suggested a carrier facing a staffing and operations strain that weather alone could not explain.
For travelers, the immediate question is no longer whether the weekend was unusual. It was. The more important issue is how long Delta can keep absorbing a system in which extra flying is accepted at 2% this year, not 37% as it was last year, without turning short bursts of disruption into a recurring part of the schedule.
