An American Airlines scheduling glitch will cost the company millions.
A recent JP Morgan report estimates the airline will play about $10 million for the error.
Last week, the Allied Pilots Association revealed that thousands of holiday flights were without pilots due to a scheduling snafu that gave too many employees time off this Christmas.
To fix it, American and the union negotiated a pay increase for pilots who offered to fly the unassigned flights.
They say no flights will be canceled.
