I am 64 and tho I've not had any scary experiences with flying, it has always been very, very hard for me to get on a plane. The last several years, I've had anxiety attacks 2-3 days before a flight. My doc gave me pills (I can't remember the name), told me to take 2 on the flight to anywhere, and the other 2 on the way home. I REALLY didn't want to resort to drugs to solve this problem.
My daughter told me about an EFT procedure that she learned. (Emotional Freedom Technique)
She did it on me just before we flew from Seattle to Amsterdam and it worked like a charm--NO anxiety at all!!
I have since learned how to do it to myself (takes about 3 min. to do), and have used it before dental appts, etc., and also before a long flight from Seattle to Florida last month--again, absolutely no panic, anxiety, etc. It was wonderful!
It's also called 'tapping'. It seems a little strange when you first do it, but hey, whatever works!
Good luck with whatever you choose
