One other thought Trashed,
I think once you leave, in this present climate, there are very few that will be able to return. I dont think IMHO that EK would take you back in a hurry. There is always Etihad for a quick command. I had a colleague who went to Qatar for a quick command. Boy is he regretting that move.
The other thing I was thinking about. Why would someone leave the Gulf to set up back home, with the thought in their mind of possibly coming back. If you are thinking that, do you really hate it that much.
