US FAA issues ground stop advisory for Alaska Airlines

The U.S. Federal Aviation Administration on Wednesday issued a ground stop advisory for Alaska Airlines, saying: "All Alaska mainline and subcarrier flights ground stopped."

The advisory said that flights for SkyWest, which provides regional service for Alaska Airlines and others, were excluded. The advisory did not provide a reason for the ground stop.

Shares of Alaska Air Group, which owns the airline, pared gains after the advisory, and were last up 2% at 10:55 ET (1455 GMT).
