Alaska Airlines resumes flights after IT outage causes widespread delays

The carrier is working with the vendor to replace the failed equipment and stabilize system performance. Despite resuming flight operations shortly after the three-hour outage, residual disruptions continued into Monday. According to Flightaware data, about 83 Alaska Airlines flights were canceled, and more than 170 delayed at the time of reporting.

Seattle-Tacoma International Airport recorded over 160 delayed flights by Sunday night. Other airports also experienced significant disruptions, including Anchorage International Airport with 34 delays and San Francisco with 28 delays.

While Alaska Airlines has ruled out a cyber-related cause for this outage, recent events have raised concerns about cybersecurity vulnerabilities in the aviation industry. Last month, Hawaiian Airlines reported an IT system breach linked to Scattered Spider, a hacking group targeting North American aviation companies.
