A strong and unreasonable fear of air or the movement of air, which can include fear of flying or being in open spaces.

Aerophobia is formed from "aero-" (from Greek "aēr", meaning air) and "phobia" (from Greek "phobos", meaning fear). The word describes a fear of air or flying.
Imagine someone who has a fear of 'air' ('aero-') — that's why aerophobia means a fear of flying.
