US carrier Alaska Airlines grounded all flights on Sunday evening due to a significant IT outage affecting its systems. The airline announced the system-wide ground stop at approximately 8 p.m. Pacific time (3 a.m. GMT on Monday), stating that the outage was impacting operations. While the exact nature of the outage was not specified, Alaska Airlines indicated that there would be lingering effects throughout the evening. The FAA's status page reflected the ground stop for both Alaska's mainline aircraft and Horizon Air. Alaska Air Group operates a fleet of 238 Boeing 737 and 87 Embraer 175 aircraft. This incident comes after a June hack on the Alaska Air Group-owned Hawaiian Airlines, which caused disruptions to some IT systems. The financial impact of that hack is still being assessed.
