PhotoThousands of American Airlines flights over the holiday season are in danger of cancellation because an error in the company’s internal scheduling system gave too many pilots time off, its union said on Wednesday. Mr. Overman said about 15,000 flights from Dec. 17 to the end of the year were affected. “I’m sorry I can’t offer any guidance other than: Stay tuned,” Mr. Overman said. It was not immediately known how the scheduling error happened. The airline assigns flights to pilots, but pilots can use the internal system to drop or trade flight assignments.
