I'm pretty sure most major airlines will run a 'fear of flying' course, which are effective in the majority of cases. Give the airline a ring or google 'fear of flying course' or somesuch, that should get you there.
I know what its like to be with a nervous passenger, I've had the circulation in my hands cut off more than once when she saw the wings flexing! Getting bounced about a bit is uncomfortable, but aircraft are designed to cope with it. Seriously, you are far safer in an aircraft than you are crossing the road!
Incidentally I was told by my father many years ago that no-one is afraid of flying - they are afraid of crashing, not that that helps!
Good luck, I hope you'll soon find flying is the nicest way to travel.
