Alaska Airlines is working to restore operations to normal as quickly and safely as possible after a significant IT outage led to a systemwide ground stop for Alaska and Horizon Air flights. The ground stop was lifted at 11:30 p.m. Pacific on Thursday, Oct. 23; the issue began earlier that day at approximately 3:30 p.m. when a failure occurred at our primary data center. Throughout Thursday and into Friday morning, we have canceled more than 360 flights on Alaska and Horizon. Additional flight disruptions are likely as we reposition aircraft and crews throughout our network. Hawaiian Airlines flights are not impacted. The IT outage is not a cybersecurity incident. We sincerely apologize to our guests whose travel plans have been disrupted. We’re working to get them to their destinations as quickly as we can. Before heading to the airport, we encourage flyers to check their flight status. A flexible travel policy is in place to support guests as operations return to normal following the IT outage.
