Alaska Airlines Resumes Flights After Nationwide Ground Stop Due to Software Issue

The Federal Aviation Administration lifted the ground stop after the airline resolved a technical problem during a system upgrade.

Alaska Airlines experienced a nationwide ground stop on Wednesday morning due to a software upgrade issue, affecting all mainline and Horizon Air flights.
The ground stop, which lasted approximately one hour, was initiated at the airline's request to address a system that calculates weight and balance.
Flights began resuming around 8:30 a.m. PT after the issue was mitigated, with the FAA lifting the ground stop shortly thereafter.
Passengers were advised to expect residual delays throughout the day and to check the status of their flights online or through the Alaska Airlines app.
The incident did not affect flights operated by regional carrier SkyWest, which continued as scheduled.
