Alaska Airlines has grounded its fleet once again due to a mystery IT issue

• Alaska Airlines grounds flights due to major IT outage, affecting 50,000+ passengers
• Company denies cyberattack; cites data center failure and ongoing system recovery
• Similar outage occurred in July 2025; external experts now reviewing infrastructure resilience

Alaska Airlines was forced to cancel hundreds of flights after it experienced an “IT outage that resulted in a systemwide ground stop of Alaska and Horizon Air flights”.

Alaska Airlines confirmed the news in a status update posted over the weekend, saying that there has been a “failure” at its primary data center. It denied this being a cyberattack or a similar, outside incident:

“The IT outage is not a cybersecurity incident,” it said. “The IT outage is not a cybersecurity event, and it’s not related to any other events.”
