Oct 23 (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 ( ALK ), 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.
