I feel personnally concerned by this thread because I'm a pilot
I'm supposed to pilot an A320 in a few years.
I can give you some tips that are well known. They depend a bit, wether you are affraid of the flight itself, or being inside a plane (sort of an claustrophobia). But this is sometimes quite linked.
- You have to know this is the most secured thing ever, EVER. It's more secured than walking in the street I guess. If you were with me in planes when I fly, you'll understand it : planes are separated sometimes 50 miles one from the other (over the ocean on some parts). Everything is not only checked but double checked. Everything ! And nothing is considered "safe" until it has a reliability best that 1 on 10^6 flights, which means 1 incident (not even accident) on 1 000 000.
- When you will fly, remember what I say, it may help you relativise : see how it moves less than a car. Being in a car on a road is more shaky.
- Turbulences are quite rare and are NOTHING. Again, when it appears, it's like driving on an old road, nothing more. And it's not a danger, it's just like that.
- Try to be relax in your seat, inspire, expire.
- Try to read. I cannot read in a train or in a plane (I get sick) but it may help you. Or watch a movie if it's possible in the company and the aircraft you are gonna fly.
- Try to sleep.
- If you're claustrophobic of if you are sick, look at the window and look far in the distance. You know it's the old trick for people who get sick on boats : you look far to find a fixed horizon so that your brain has something it understands better. If you are afraid of being high, maybe it's better to look inside. You'll choose.
- take some pills
- chat with someone else, it will help you relax and focus on semething else.
- when the engines will give full power at take off, try to think "oh my god it's awesome" and try to find the awesomeness in the situation. It may help you realize it's actually uber cool and that people would have given everything for centuries to live that.
Anyway, you'll discover that it's all in your head. Technically, it's very quiet, more calm than any train or car, and actually, it may be fun
