Updated:SEATAC, Wash. —
A computer glitch canceled 57 flights nationwide and delayed four that were scheduled to leave Sea-Tac Friday night.
Seattle-Tacoma Airport spokeswoman Christina Faine said the flights were bound for Sacramento, Calif., Oakland, Calif., Salt Lake City and Las Vegas. She said one departed before 11 p.m. and an airport duty manager said the others were expected to follow shortly.
The problem prevented the airline from being able to check-in passengers, print boarding passes or monitor the weight of each aircraft.
Brad Hawkins, a spokesman for the Dallas-based airline, told The Associated Press that around 250 flights were affected at least temporarily.
Flights in the air were unaffected.
