I would have thought the beauty of the Middle East airlines is the job security, especially to anybody who has been through a redundancy process. The pay isn't bad either but be in do doubt as far as your employer is concerned you are here to work. Quality of life doesn't come into it.
Do the job, don't mess up, take the money and save as much as you can. Then retire early to somewhere you really want to live. That is where the quality of life comes into it. I reckon that by working in the Middle East for 15-20 years I can retire 10 years earlier than I could if I'd stayed in Europe.
