The only exclusion was for SkyWest, which provides regional service for Alaska Airlines and others.

Alaska Air issued this statement about the ground stop:

This morning we experienced an issue while performing an upgrade to the system that calculates our weight and balance. A ground stop for all Alaska and Horizon flights was instituted at approximately 7:50 a.m. We’re working to resolve the issue as quickly as possible. We apologize for the inconvenience and encourage guests to check the status of their flights on alaskaair.com or the Alaska App prior to heading to the airport.

Dave Young, another Alaska passenger, said he typically has no trouble with the airline’s service.

“The only real difficult time we had was in January, with a Hawaii trip,” he said. “They had to keep changing planes.”

January saw Alaska Airlines under heavy scrutiny, after a plane’s door plug blew out mid-flight over Portland.

The airline says the software system problem that triggered this ground stop is fixed, and there are no safety concerns with any aircraft.

The company asked those with reservations to check the status of their flights on .
