I like to fly but just for a moment at take off and landing, I get a bit jittery. Now Dh does not like to fly but with his job he does often so.
We always bring something to do while waiting to board, books, I-pad, lap top, a few times we have a had a glass of wine, only one glass. Trying to stay busy is helpful so that you don't dwell on the flight.
I say this with the most respect for whatever your personal belief's are, I am just stating what works for me. I always say a prayer, before take off and landing. I find this to be the most helpful and reassuring for me.
Have fun on your trip.
