Just from what I've heard talking to guys that work at two (EY EK) out of the three, there are guys that have left EY and QR to go to EK. EK has more financial benefits (Provident fund, yearly bonuses, etc...) and you don't have to live in Doha or Abu Dhabi. I've been to Abu Dhabi and thought it wasn't that bad looking, more green and less artificial than Dubai, but I say that living in Dubai which most seem to prefer. Never spent anytime in Doha besides on a turnaround, but reading on pprune I get the feeling it wouldn't be a nice place to live...... Just my $.02, I'd go to EY as they have lots of planes on order and are still small compared to EK. Yes there will be growing pains at EY, but it seems like upgrade would be faster. At the end of the day all middle east airlines have the same problems: DECs, flexible contracts, and variable living conditions. Get what you can in as short as time as possible and move back to your home country.........
