What caused the Alaska Airlines ground stop?
Alaska Airlines Boeing 737-8 (Alaska Airlines)
Alaska Airlines briefly grounded all flights Wednesday due to a technical issue.
The Seattle-based airline said in a statement it requested a ground stop for all Alaska and Horizon air flights out of an abundance of caution after it "experienced an issue while performing an upgrade to the system that calculates our weight and balance."
The ground stop lasted from about 7:30 a.m. to 8:30 a.m. Pacific time, when flights began resuming. The airline said it expected residual delays throughout the day and recommended that travelers check their flight status before heading to the airport.
