Alaska Airlines has resumed operations following a temporary suspension of all flights due to a software outage that affected its entire fleet and that of its regional subsidiary, Horizon Air. The disruption began late Sunday night, when the airline requested a full ground stop for over 200 aircraft operating under the Alaska Airlines brand. The issue was reported around 11 p.m. Eastern Time and was confirmed by the Federal Aviation Administration (FAA).
The suspension was later extended to include Horizon Air, a wholly owned subsidiary of Alaska Airlines. This move halted all take-offs across the airline's network, as the company sought to resolve the software-related technical difficulties affecting its systems.
By approximately 2 a.m. on Monday, Alaska Airlines announced that the ground stop had been lifted and that flight operations were gradually resuming. While the immediate software issue had been resolved, the airline acknowledged that the disruption would continue to have knock-on effects.
“As we reposition our aircraft and crews, there will most likely be residual impacts to our flights. It will take some time to get our overall operations back to normal,” the airline said via social media.
The incident highlights the critical role of operational software in modern airline management and the vulnerability of air travel to technical failures. Although flights are now resuming, passengers are advised to expect delays and disruptions throughout the day as Alaska Airlines works to return to full normal service. The airline has not yet released further details on the nature of the software issue.
