Alaska Airlines faced significant operational disruptions on Thursday as a technical issue forced the grounding of all flights across its US airports. The airline announced in a statement that it was grappling with an IT outage that severely impacted its operations, leading to the implementation of a temporary ground stop. While the carrier did not specify the duration of the outage or the exact number of affected flights, it assured that efforts were underway to restore normal operations. The Federal Aviation Administration (FAA) confirmed that the ground stop also impacted Horizon Air, a subsidiary of Alaska Airlines. Based in Seattle, Washington, Alaska Airlines is a major player on the US West Coast, serving 140 destinations across 37 states and 12 countries. This incident marks the second IT-related disruption for the airline this year, following a similar outage in July that halted flights for approximately three hours. The recent US government shutdown, which began earlier this month, has further complicated air travel, with shortages of air traffic controllers causing delays at several airports. Alaska Airlines has yet to respond to media inquiries regarding the latest outage.
