American Airlines computer glitch causes holiday pilot shortage.
Mr. Tajer said that while flights remained unassigned, the terms of Friday's agreement were expected to attract enough pilots to cover the gap.
American Airlines is looking to calm passengers who've booked flights in December, with the carrier saying its crews will be ready for lift off.
The carrier and the Allied Pilots Association didn't immediately disclose details of their pact on Friday but said it should ensure that American, the world's largest carrier, will maintain a full December flight schedule. In addition, we have more reserve pilots on hand in December than normal months and they provide us with the ability to fly numerous trips that are now uncovered.
