"Alaska and Horizon Airlines Resume Operations After Ground Stop"

Alaska Airlines and Horizon Airline flights have resumed after a temporary ground stop caused by issues with a system upgrade for weight and balance calculations, leading to delays for at least 150 flights. The ground stop, requested by Alaska Airlines, lasted from 7:30 a.m. to 8:30 a.m., with the FAA citing a system outage. While some passengers experienced delays, others reported minimal impact, and the airlines advised customers to anticipate residual delays throughout the day.
