- Alaska Airlines grounded all flights nationwide Thursday evening due to a tech outage.
- The FAA said the ground stop also covered its regional arm, Horizon Air.
- It's the airline's second major IT outage this year — it also grounded flights in July for that reason.
Alaska Airlines said it had grounded all flights across the US on Thursday evening after a tech outage disrupted its operations.
The Federal Aviation Administration said the carrier also requested a ground stop for its subsidiary, Horizon Air, for more than two hours.
In July, Alaska Airlines also grounded its flights because of an IT outage.
"Alaska Airlines is experiencing an IT outage affecting operations. A temporary ground stop is in place. We apologize for the inconvenience," Alaska Airlines said in a statement on social media.
Alaska Airlines has its primary hub on the West Coast, but serves more than 140 destinations across 37 states and 12 countries.
Representatives for Alaska Airlines did not immediately respond to a request for comment from Business Insider.
