American Airlines says it’s restored most of the affected flights after a technical glitch in the company’s scheduling system reportedly forced the airline to drop thousands of trips this month.

More than 12,000 flights between Sunday and the end of July were wiped out on Friday night because they lacked either a captain, first officer or both, after pilots had changed their assigned trips, the Allied Pilots Association, the union that represents American Airlines pilots, told CNBC.

American Airlines said in an emailed statement that it had already “restored the vast majority of the affected trips and do not anticipate any operational impact because of this issue,” including the July 4 holiday weekend. A spokesperson for American couldn’t provide details about how many flights were either dropped or restored.
