I think much of my anxiety is pre-flight anyway. The worries of getting your gate, going through security. I flew two times recently within a month and it was fine once I was in the air, but most of the fear came before the flights.
sure, I still experience that as well. Seeing a long as hell line when you know you flight is boarding in half an hour is really anxiety inducing. I tend to get to airports much earlier than I actually need to be there in order to mitigate this. Sometimes it works, sometimes I just end up sitting on the other side for hours wondering why the hell I went to the airport 2 hours ahead of time :)
