Earlier, the airline had issued a system-wide ground stop for both Alaska and Horizon Air flights due to the outage, according to an advisory from the US Federal Aviation Administration (FAA).The airline told AFP on Sunday that it “experienced an IT outage that’s impacting our operations” and that it “requested a temporary, system-wide ground stop… until the issue is resolved.”
The FAA status page showed all destinations being impacted by the ground stop of Alaska’s mainline aircraft. The FAA did not immediately respond to AFP’s request for comment.
Alaska Airlines had apologised for the disruption and warned of residual operational impacts, urging travellers to check their flight status before heading to the airport.The statement, also posted on X, drew a backlash from frustrated passengers.
“This is brutal. We’ve been sitting at the airport for two hours,” wrote one user, Caleb Heimlich. Another, BetterDays, commented: “This started at 8 pm & you’re just posting this now?! Your service has gone way down over the last 5 years.”
The outage comes more than a year after a door plug section of a newly delivered Boeing 737 Max 9 blew out during an Alaska Airlines flight between Portland, Oregon, and Ontario, California, in January last year. All 171 passengers and six crew members survived, but the incident led the FAA to ground many Boeing 737-9 aircraft operated by US airlines.
Last month, US investigators said Boeing’s failure to provide adequate training to manufacturing staff was a key factor in that near-catastrophic incident.
Alaska Air Group operates a fleet of 325 aircraft, comprising 238 Boeing 737 planes and 87 Embraer 175 aircraft, according to its website.
