American Airlines says its flights are expected to face disruption for the rest of the day, depending on how long the FAA's nationwide ground stop lasts. Southwest Airlines has told employees it is working with the FAA on a resolution.
Both statements were reported by CNN. They follow United's statement, covered earlier on this blog.
American said flights already in the air can continue to their destinations. That matches United's position and the terms of the ground stop reported earlier, which halts departures rather than ordering airborne aircraft to land.
The airline said:
"It will be all hands-on deck across American to get customers on their way as soon as possible when the FAA lifts this ground stop"
Southwest's message to employees, as reported by CNN, said:
"We are aware of the current nationwide ground stop and are actively working with the FAA for resolution"
CNN aviation correspondent Pete Muntean said cancellations and delays are increasing. "This is not going to be a short-haul story. This is going to last at least likely until tonight," he said on air. That is his forecast and has not been independently checked.
