This has been a very interesting thread to read!!
I turned down a position on the A340 with VS last year. I stayed with my current airline in the RHS. For me it was a very very big decision to make, I had sleepless nights thinking about what to do.
To be honest there has not been a week gone by when I have thought, did I make the right choice? - It looks like I did.
Ron good luck with your choice!
