“At approximately 8 p.m. Pacific on Sunday (0300 GMT on Monday), Alaska Airlines experienced an IT outage that’s impacting our operations. We requested a temporary, system-wide ground stop for Alaska and Horizon Air flights,” Alaska said in an emailed statement to Reuters on Sunday evening.
The Seattle-based airline said there would be residual impacts to its operations throughout the evening, without providing more specific details.
The FAA did not immediately respond to Reuters’ requests for comment outside regular business hours.
The FAA status page showed all destinations being impacted by the ground stop of Alaska’s mainline aircraft, and Horizon’s ground stop.
Alaska Air Group maintains an operational fleet of 238 Boeing 737 aircraft, and 87 Embraer 175 aircraft, according to its website.
In June, Alaska Air Group-owned Hawaiian Airlines said some of its IT systems were disrupted by a hack. Alaska Air Group said it was still determining the financial impact of the hack.
