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.

A ground stop was issued Thursday evening at George Bush Intercontinental Airport due to air traffic control staffing issues, according to the FAA.

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.

According to the Federal Aviation Administration (FAA), the ground stop for Bush Airport (IAH) is in effect until 6:30 p.m. Thursday. An advisory says the stop is due to staffing. The stop has a 30–60% chance of extending past 6:30 p.m. Flights departing from Bush Airport are also being delayed by an average of 30 minutes due to construction.

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