I know how it feels..
I spent 6 years in my first company and then it went bust.
So I moved to a UK company and I have to agree with Brix here, not fun at all to work for a UK management!
When I finally got the chance for an upgrade it was at a base far from my family. So I turned it down and moved company is back in the bottom of an seniority list as f/o, same place I was 12 years ago, same base...
My point is, if you move you cannot be sure you will ever get the social life quality you properly have now.
Also you might have to spend a few years flying with commanders with half your experience (can be a bit annoying) and then not get an attractive upgrade.
I would wait for the financial crisses to pass before a move, maybe I do it as well then.
