One of the trade pubs had an article and ex-pats working abroad. Quite a lucrative deal for those with little connections or commitments to the home land. Some were 30/30 (On/Off), some had admirable vacation plans. Almost all had phenominal salaries. I don't recall the exact figure, but I believe you're first US$70K is tax free abroad. Many pay per diem, enough so to cover living expenses. The article mentioned some send their entire pay checks back to the U.S. and live off per diem. A lot of jobs even provide apartments and transportation to/from the airport.
Most jobs are contracted for two years. Some require you to pay for your initial type, some don't.
About 15 years ago I was offered a G3 position in Denmark. I had three phone interviews in one day. I get a call early the next morning (it was a Thursday) that went something like this:
E(mployer) - "We like to offer you the position on the G3, are you interested?"
M(e) - "Absolutely!"
E - "Fantastic! Can you be here and ready to start Monday?"
M - "Well, thats pushing it. Can I call you back this afternoon and let you know if I can wrap everthing up here in two days?"
E - "Sure, we'll fax you the contract right now. When you've filled it out, fax it back with a photocopy of your check."
M - "Check? :erm::erm: "
E - "Yes, did I forget to mention you pay for your own type rating?"
M - "NO!"
E - "Don't worry, everyone manages it."
M - "How much?"
E - "$18,900."
M - "Sorry to waste your time...:angryfire "
Now, that was a long time ago and from what I've heard and read, it's much more professional now and everything is on the table before an offer is made.
Do your homework. Find out what it's like to live in a particular place. Remember, a lot of middle east and muslim countries don't allow alcohol. Yes, there are ways around it if you like a beer every now and then. Just make sure you've read the fine print in your contract! I knew a Riyad based British crew flying for the royal family. They lived in what amounted to a secured campus, much like a condo. They secretly made their own "hooch" and enjoyed a great lifestyle. However, they weren't allowed to bring their wives - significant others with them so that can be a strain to some.
Good luck in your search!
