Many of us aren’t wild about going up in the air in a bus with wings. But if the fear is so strong that it causes a problem with your job or keeps you from visiting family, you may have aviophobia. It starts with a panic attack -- sudden, intense fear -- on a plane. It may happen after a major life event (a wedding, funeral, or divorce, for example). If you have one, there’s a good chance you won’t want to fly again.
