Alaska Airlines resumes operations after it grounds all flights due to IT outage: ‘229 flights were cancelled’

Alaska Airlines said on Thursday its operations have resumed after it had to ground its planes for hours because of an information technology outage.

The Alaska airline said in a statement that 229 flights were cancelled because of the outage and that more flight disruptions were expected as it worked to “reposition aircraft and crews,” the Associated Press reported.

Earlier in the day, the company said in a post on the social media site X that it imposed a “temporary ground stop.”

It recommended that passengers check their flight status before heading to the airport.

“Alaska Airlines is experiencing an IT outage affecting operations. A temporary ground stop is in place,” the airline said.

“We apologize for the inconvenience. If you're scheduled to fly tonight, please check your flight status before heading to the airport,” it added.

The grounding affected Alaska Air and Horizon Air flights.

Hawaiian Airlines, which was bought by Alaska Air Group last year, said its flights were operating as scheduled.

In July, Alaska grounded all of its flights for about three hours after the failure of a critical piece of hardware at a data center.

There has been a history of computer problems disrupting flights in the industry, though most of the time the disruptions are only temporary.
