worktolive,
I wouldn't expect a proper contract to be honest. But then stranger things have happened.
When I read your first post you didn't strike me as someone really desperate to be in Europe (maybe I'm wrong?). If it was me I would not join RYR unless my family or I was unhappy.
I know there are horror stories in the middle east, but don't fall into the trap of the grass being greener. If you are tired of the ME, I promise you'll get tired of being based in a country you don't want to, commuting on your days off. Depending on where you live an where you're based, commuting can be anywhere between 4 - 14 hours and 1-4 flights to get home, and then do it again 2 days later. Consistently high load factors make it all the more difficult.
Get your command if you're close to it. Or get a Ryanair command with the intention of leaving and doing back to the ME/Asia as a DEC somewhere. Ryanair is a great place to start your career, but I don't see it as a progressive career move. Personal opinion, of course.
