After a seven-hour outage that grounded planes across its network, Alaska Airlines said it restored operations Thursday night following a “major IT outage.”
But flight cancellations were already piling up for Friday.
And the Seattle-based airline warned overnight that more flight disruptions are likely as it recovers from the outage that affected its entire network. The carrier issued a flexible travel exemption to travelers willing to change their travel plans.
A “significant” IT outage
Alaska initially requested a nationwide grounding for its flights around 7:21 p.m. EDT (4:21 p.m. PDT) on Thursday, citing a technological glitch that had affected its operations.
The disruption affected both Alaska’s core operation and its flights operated by regional subsidiary Horizon Air, but not Hawaiian Airlines, which is run by the same parent company as Alaska.
The grounding caused massive flight delays and cancellations at America’s fifth-largest airline, and left passengers stranded at airports across the country, especially in major hubs on Alaska’s west coast, from Seattle to Portland, San Francisco, Los Angeles and San Diego.
In total, the service disruption in Alaska caused about 229 flight cancellations, the airline said. Added to this were hundreds of additional delays. Alaska’s Seattle-Tacoma International Airport (SEA) home base was the hardest hit, with more than 10% of all departures canceled Thursday, according to FlightAware.
More travel problems expected on Friday
Alaska was able to resume service around 2:30 a.m. EDT (11:30 p.m. PDT), the airline said, although it warned that additional disruptions were likely as it repositioned planes after halting departures for more than seven hours.
As of 4:30 a.m. EDT on Friday, Alaska had preemptively canceled nearly 100 flights for Friday, according to data from FlightAware, at least 12% of its network.
