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

In a separate statement, the FAA said the carrier "asked the FAA to pause the airline's mainline departures nationwide." It did not provide a reason for the stoppage.
