back to the main issue!
Chewy,
Your friend obviously needs some good advice from a wise old Jedi as she is possibly feeling isolated in thinking she's unusual in having a job in the thing that terrifies her.
It's unlikely that she's phobic else the she wouldn't have been ok up until the turbulent canada flight.
She can go all out and do one of the "fear of flying" courses that a few airlines do (eg I think britannia do one) but they cost a few bob (and frankly a damn good holiday for the same money might be a better solution)
I understood that NLP and hypnotherapy are more for phobias whereas cognitive-behavioural therapy (CBT) may be more appropriate. This is more of a chat to reason things out.
Not saying she is, but remember that running away always makes the problem worse
