Delta is canceling hundreds of flights due to crew and scheduling challenges, an internal memo shows

""We apologize to our customers for higher than usual cancellations this weekend due to crew resources," a spokesperson told Business Insider in an emailed statement."

""23.M.7, never intended for consistent daily operations, is now being used 10 to 15 times more than last year," the memo said."

""Acceptance rates for these open trips have plunged to 2% from about 37% year over year," the memo stated, highlighting the staffing challenges."

""Flight operations-related cancellations are now more than 10 times higher than historical levels and account for 35% of Delta's mainline cancellations," the memo indicated."

Delta Air Lines has canceled approximately 500 flights recently, significantly more than its competitors. The cancellations are attributed to crew resource issues, with a sharp decline in pilots accepting extra flights. Acceptance rates for open trips have dropped from 37% to 2%. Delta's complex staffing system, 23.M.7, is being used excessively, leading to inefficiencies and increased costs. Flight operations-related cancellations have surged to 35% of mainline cancellations, up from 7% last year, indicating a critical staffing challenge for the airline.
