I have just joined EK having come from a reasonable charter job in northern europe, I would think very carefully about coming out here as the grass definately isn't greener on the other side.
You do get to see some interesting places aroung the world, but as with most airlines the management don't give a toss about you, and Dubai is a very expensive place to live in, and pay rises are non existent.
The place is full of people from the sub continent who basically hate you, and to say that there are some vain western expats around here would be a huge understatement, do not expect to feel welcom when you arrive.
However the weather is nice, good food, interesting places to visit and a few other things, BUT choose carefully.
.....i'll have a lie down now.
