AviationNews – Alaska Airlines is working to restore normal service this weekend after a significant, system-wide IT outage crippled its network. The massive failure, which began Thursday, led to a nationwide ground stop and the cancellation of over 400 flights, stranding tens of thousands of travelers.
The disruption began on Thursday, October 23, when a critical failure occurred at the airline’s primary data center. This forced Alaska Airlines and its regional partner Horizon Air to halt operations, ultimately disrupting travel plans for more than 49,000 passengers over two days. The airline has been clear that the event was a technical failure and not related to a cybersecurity incident.
An airline’s core IT system manages everything from flight scheduling and crew assignments to passenger check-in and baggage. When this system failed, it created a cascading effect across the entire network. While the main systems are now back online, the airline is still managing the fallout, with a small number of flights canceled Saturday to reposition aircraft and crews left stranded by the shutdown.
In response, the airline issued a public apology for the widespread disruption. The carrier stated it is “immediately bringing in outside technical experts to diagnose our entire IT infrastructure” to ensure system stability, acknowledging that this level of performance was unacceptable.
This is the second major IT failure to hit the airline in 2025, raising significant concerns about the resilience of its technology. As the company begins a full review of its systems, it is urging all passengers to check their flight status online or via the airline’s app before heading to the airport.
While the worst of the crisis appears to be over, Alaska Airlines is still in recovery mode as it works to get its schedule back to normal. The focus has now shifted to a long-term fix to prevent future meltdowns and rebuild passenger confidence.
