No fear of flying commercial. I was always afraid on my initial takeoff when taking flying instructions. Back to commercial flying - what causes me fear is getting the middle seat between two (American) football linemen.
However I am always uncomfortable being alone in a strange, large city. Small towns and unfamiliar country hold no trepidation for me though.
Fortunately or maybe unfortunately depending on how you look at it, I had a ruptured eardrum (from a simulated emergency dive in an altitude chamber) years ago and my ENT doctor told me to never fly again as the pressure changes normal in commercial airlines could cause a re-rupture. When he put that on his letterhead, I took it to my boss and have never flown since.
