Hi flight04,
i am guessing a little here, but i would imagine after 2 years you will be getting paid around 6000 dhs per month as crew in Etihad. So 3 times that back home in OZ is approx 5700 AUD. After tax that is some serious money. Where do i sign up ?.
Good luck getting a job back home in Australia, there is no comparison between the countries for sure.
