If you have a good job that you are happy with then don't give it up just to come here. EK is ok but it's just another airline, yes it's on the up at the moment, but how long will it last?
Dubai is an ok place to live, the airline is an ok place to work, but it's not worth jumping up and down and writing home about that's for sure!
If you do come here you WILL see that the grass is NOT always greener on the other side.
Good luck.
