Alaska Airlines passengers wait in a line near inoperable check-in computers, Monday, Oct. 8, 2012, at Seattle-Tacoma International Airport in Seattle during a system-wide outage of the computers the airline uses to check in passengers. The computers Alaska Airlines uses to check in passengers stopped working at 7:40 a.m. Monday, causing long lines of frustrated passengers who were unable to board flights that were delayed.

SEATTLE — There's been no quick solution to a computer failure that cut off Alaska Airlines' ability to put passengers on planes, creating long lines at many West Coast airports.

The failure has caused delays at the Seattle-based airline's entire network of 64 destinations, which also includes airports in Alaska, Mexico and Canada. Alaska Airlines has an average of 436 flights a day.

Airline spokeswoman Marianne Lindsey says technicians are trying to restore the reservation network that was lost at 7:40 a.m. Monday.

The airline says the problem was caused when a Sprint fiber optic network in the Midwest was cut and Alaska Airlines lost its connection to the Sabre ticketing system.

The airline had hoped for a partial solution by noon Pacific time, but there was no indication a fix was imminent.
