Alaska Airlines plane at SFO

Alaska Airlines flights, including those out of San Francisco International Airport, were grounded nationwide for one hour on Wednesday after the carrier experienced a technical issue during a system upgrade. 

Alaska Airlines flights resumed out of San Francisco International Airport Wednesday after the Federal Aviation Administration lifted a ground stop that temporarily halted the carrier’s flights across the United States earlier that morning.

Company officials said they requested a ground stop at 7:30 a.m. due to a technical issue which took all Alaska flights and flights for subregional carrier Horizon Air temporarily out of service. The issue was resolved roughly an hour later and the ground stop expired just after 8:30 a.m.
