Have not flown in some time, but had to fly in the past. Detested it, was thoroughly terrified. Knew I had to do it so shut my mind off, pretended I could not see or hear, took aspirin and got on. One time I had potent drinks on the blasted thing which helped much.
Bring something to plug up ears, reward yourself with a magazine or book, maybe a book of puzzles. Get on and go into hyper mind control to forget where you are. Some people actually enjoy such torture. We can learn to endure it. Truth is it is more dangerous to get in the car. You'll be fine.
