We canceled our Christmas trip to Seattle because during our September/October trip we encountered many uncovered noses in the airport and several in the plane. With the cases on the rise, the possibility of some of these "naked" people are asymptomatic has also increased. UA FAs couldn't get the passengers to correctly wear the masks. Having 4 unmasked people less than 36 inches from me for 5 hours is too much stress for me. If the FAs were able to get passengers to correctly wear masks, I would have kept on flying. Sadly that is not the case. I think the FA are tired for policing the mask policy as well.
