Alaska Airlines, one of the largest US carriers based in Seattle, grounded all its flights nationwide on Thursday due to a major IT outage.
The disruption also affected its regional subsidiary, Horizon Air. Together with Hawaiian Airlines, the group serves 140 destinations worldwide, spanning 37 US states and 12 countries.
The Federal Aviation Administration (FAA) issued a temporary ground stop, leaving thousands of passengers stranded.
The outage, traced to a failure at Alaska Airlines’ main data center, affected booking systems, mobile apps, and other essential operational services. Over 140 departures were delayed at major hubs, including Seattle-Tacoma International Airport.
“This was an unexpected disruption, and we sincerely apologize to our passengers,” Alaska Airlines said on social media, urging travelers to check flight status before heading to airports. Hawaiian Airlines reported no impact and continued normal operations.
This is the second IT-related outage for Alaska Airlines this year because a similar incident in July grounded all flights for three hours. Flexible travel policies are now in effect as the airline works to restore full service.
