(Reuters) -Alaska Airlines has requested the grounding of its flights at all airports on Thursday evening due to an unspecified tech-related issue, according to a U.S. Federal Aviation Administration advisory.

The ground stop also applies to Alaska Airlines's subsidiary Horizon Air, the FAA advisory showed.

"Looks like we are experiencing a temporary technical issue. We are aware of the issue and are actively looking into it," Alaska Airlines said in an alert posted on its website.
