DALLAS (AP) - Southwest Airlines Co. says an outage of its airport-technology systems was preventing passengers nationwide from printing boarding passes for part of Tuesday.
Airline spokeswoman Christi McNeill said the problems affecting its check-in kiosks were fixed by late afternoon.
Some passengers posted comments and photos on Twitter of long lines at Southwest ticket counters and said agents were filling out boarding passes by hand.
McNeill said customers could check in from home or on mobile devices but not at airports, and reservations were not affected.
She said the Dallas-based airline didn't know what caused the outage.
