The number of planes decommissioned continued to account for more than twice the normal daily average of 20 aircraft, the airline said Tuesday, and there is "no common theme" among the problems reported mechanical The airline has about 750 Boeing Co. 737 aircraft and operates nearly 4,000 flights a day.
The Brother Association of Aircraft Mechanics, which represents 2,700 Southwest employees, said its members were working as usual. The mechanics' union rejected a tentative contract agreement in September.
"Members work on normal hours and work overtime," said Bret Oestreich, the union's national director, at the end of last week. "Overtime may have been increased by the workload."
In 2017, Southwest accused the union of encouraging members to refuse to work overtime in order to put pressure on the company during contract negotiations. A lawsuit filed by the airline was suspended in 2018 after the conclusion of an initial agreement.
