Alaska Airlines recently experienced a system issue during an upgrade, leading to a temporary grounding of their flights. The issue occurred during a system upgrade that calculates weight and balance. As a precaution, Alaska Airlines requested a ground stop for all Alaska and Horizon flights, which went into effect around 7:30 am PT. The ground stop was lifted at approximately 8:30 am PT after the issue was addressed.
The Federal Aviation Administration had been involved in grounding the Alaska Airlines flights across the nation. Following the resolution of the issue, Alaska Airlines has started releasing flights. However, passengers should expect residual delays throughout the day. The airline apologizes for any inconvenience caused and recommends that passengers check the status of their flights on their website or app before heading to the airport.
