U.S. airspace may reopen at 15Z (11 a.m. EDT). However, that decision is under review at the White House. A senior FAA official told AOPA President Phil Boyer that even though a notam has been issued saying that flight operations can begin at 15Z, that decision may be changed.
However, the FAA did approve the restart of flight operations in Alaska last night. Recognizing the extreme importance of general aviation in the 49th state, the FAA told AOPA that it expected that aircraft would continue to be allowed to fly in Alaska regardless of what happens in the lower 48 states.
AOPA has been in contact with the FAA throughout the night and is continuing to work to get general aviation flights back in the air.
