Alaska Airlines resumes operations after equipment failure grounds all flights

Alaska Airlines has resumed operations after the failure of a critical piece of hardware forced the airline to ground all its flights for approximately three hours, but the effects will linger into Monday, the company announced.

The carrier issued a system-wide ground stop for Alaska Airlines and Horizon Air flights around 8 p.m. Pacific time Sunday. The stop was lifted at 11 p.m., the Seattle-based company said in a social media post. More than 150 flights have been canceled since Sunday evening, including 64 Monday.
