An information technology outage has prompted Alaska Airlines to ground its planes, the airline said Thursday.

Alaska Airlines is currently facing an IT outage that has led to a temporary ground stop affecting its operations.

Alaska Airlines grounded all its flights nationwide following a tech outage Thursday afternoon — the second time in roughly three months. The airline announced a “temporary” ground stop over the issue and advised customers to check their flight status before heading out the door.

Alaska Airlines operations have been restored after a significant IT outage resulted in a system-wide ground stop of flights for Alaska and Horizon, according to Alaska Airlines. The ground stop was lifted at 11:30 p.

Uncertainty looms as airlines prepare for nationwide flight reductions, including at Portland International Airport.

Alaska Airlines says it is grounding its planes because of an information technology outage. The company said in a social media post on X Thursday that it is imposing a “temporary ground stop.”
