The hardest parts of overcoming your fear of flying is actually facing it. All the preparation in the world won’t change the fact that one day you’ll have to step on that plane.
Most fearful flyers imagine that when that moment comes they’ll feel the same as they do right now, but the fact is that with the right preparation, with support and help and knowledge of how to relax will make that moment easier to face.
We have courses on our non flying but real aircraft or on a proper airline simulator ( not a fairground ride type) a real multi million pound device. There’s no better way to prepare for the time that you face your fear.
