On the contrary to what has been said, I have a friend who has been an FO at Virgin for 8 years, he doesn't have a sniff of command, but he's having the time of his life, and the lifestyle suits him down to the ground....lucky bugger is mainly flying caribbean routes at the moment....He doesn't have a family to support so I guess that changes your view on things, but I think this is still the dream job for most UK pilot.
Definitely for me anyway.
