The only thing I hate about flying is airports. Driving there, parking, getting from parking to terminal with luggage, rude people, bad odors, dirty toilets, long waits (because I'm always early), and just in general a day "wasted".
Once I'm on the plane and installed in my real estate (seat), I calm down immediately.
Take an Ipod to listen to do, and something else to do with your hands. Keeps you occupied and before you know it they're announcing the local time and temperature at your destination.
