You know what? I had fear of flying. I did a training with a pilot in a simulator, but it was in the cockpit. I don't have fear of flying in a simulator or in the cockpit. I have fear of flying as a passenger, I'm sit in a chair. That's what I would have liked during my training. I told that to Air France and they did not understand but this might seriously be useful.
BA (and presumably other airlines) run fear-of-flying courses where you have some ground sessions with flight crew explaining what happens during takeoff/landing, what noises you might hear, etc. Then you go up for a short flight as a passenger to sort of re-enforce what you learned earlier. https://flyingwithconfidence.com/
first fly to the UK to take the course...
