The fear receives more attention than most other phobias because air travel is often difficult for people to avoid, especially in professional contexts, and because the fear is widespread, affecting a significant minority of the population. A fear of flying may prevent a person from going on holiday or visiting family and friends, and it can cripple the career of a businessperson by preventing him or her from traveling on work-related business.
Different people are frightened by different aspects of flying. For some it is the claustrophobic feeling of being enclosed in the cabin.
Others have the common problem of not being in control of the situation, and then there's the group fed by disaster movies and the media
into becoming paranoid the plane will crash - due to extreme weather, mechanical failure or pilot error. A fear of heights can also be underpinning a fear of flying.
Whatever the detail of our fear, it is never logical and won't be overcome by logical argument. Try convincing someone who is Arachnophobic that (British) spiders are harmless!
Invariably our fear of flying is rooted in our limiting beliefs and has developed as an extension of those beliefs over time.
