The airline said in a statement that it had experienced "an IT outage affecting operations" and issued a temporary ground stop, which has now been lifted.

Alaska Airlines says their flight operations have been restored after a "significant IT outage" led to a system-wide ground stop of hundreds of Alaska and Horizon flights. The ground stop was announced by Alaska about 6:20 p.m. CT Thursday. It was lifted about 1:30 a.m. CT, according to the airline.

The Federal Aviation Agency (FAA) issued a ground delay until 10 p.m. at Dallas Fort Worth (DFW) Airport Monday due to staffing.

A laska Airlines said Friday it is still working to "normalize operations" a day after a significant IT outage resulted in a system-wide, hourslong ground stop of flights for Alaska and Horizon.

Alaska Airlines said late on Oct. 23 that it was restoring operations after grounding flights for about three hours due to an unspecified technology outage. "We are actively restoring our operations following an IT outage," the airline said on social media.

A ground stop delayed flights for a few hours at Chicago’s O’Hare International Airport on Saturday because of an equipment outage.
