Alaska Airlines recently experienced a significant IT outage that led to a nationwide grounding of its flights on Thursday, October 23, 2025. This technical issue affected multiple critical systems, preventing planes from taking off and disrupting travel for thousands of passengers. The airline, including its regional subsidiary Horizon Air, was forced to implement a temporary ground stop as a result of the system-wide failure, which originated from a problem at its primary data center.

This incident marks the second major IT-related disruption for Alaska Airlines in recent months, following a similar three-hour outage in July 2025. While the safety of flights was not compromised, the outage caused widespread delays and cancellations, with many travelers left stranded and advised to check their flight status before heading to the airport.
