DALLAS - (AP) -- Some Southwest Airlines flights are being held up while the airline tries to fix a technology outage.

Southwest Airlines Co. said Wednesday that it began having intermittent problems with several systems after an outage.

A spokeswoman says the Dallas-based airline is dealing with flight delays across its system and temporarily stopped flights that have not left their airport gate.

The spokeswoman says systems are gradually coming back but it may take time before the airline resumes normal operations.
