I am afraid of heights too. I don't love flying but don't mind it that much. If the drive is over 8 hrs then I would fly. And when you are tall no seat is comfortable especially when your knees are jammed in the back of the seat in front of you. The first time is the scariest if you don't know what is going to happen. When they have to de-ice the wings several times before you take off that is pretty scary too.
