SEATTLE -- Several airlines are experiencing flight delays nationwide because of a problem with a computer system they use for services such as reservations, check-ins and online booking.
Alaska Airlines spokeswoman Bobbie Egan says about 50 of its flights departing Monday night were delayed by an hour or less due to the outage.
Egan says the problem originated with Sabre, a company that Alaska and many other airlines use for technology services.
She says the problem began about 8:40 p.m. PDT and all systems were restored by about 11 p.m.
Nancy Castles, a spokeswoman at Los Angeles International Airport, says 17 flights there experienced delays of up to 45 minutes.
Officials say other airlines affected include American, Jet Blue, Frontier, Virgin America, Qantas and British Airways.
Flights in the air were not affected.
