Experiences may vary. I moved my daughter down to Los Alamos in mid December and had no choice except to fly back. I flew Delta; they had every other seat vacant so I wasn't sitting next to anyone. I wore an N-95 mask the whole time; passengers in the SLC terminal were keeping social distances. This seemed about as safe as it could be made under the circumstances but I was happy to get off the plane. I received the first vaccination about 10 days ago.
