Airtoday has a point , I spent 2 and a bit years in Dubai with Aerogulf, didnt get rich by any means- but gained alot professionally, got typed in a 212 and enjoyed a different culture and enviroment to which myself and my family had previously experienced. And made alot of friends and a few enemys!
Socially its a great town , with the Rugby sevens ,concerts, Dubai World Cup etc etc
The job is a no brainer except for the night offshore flights ,which hones your night flying and IFR skills.
Give it a try , you wont get rich ,-might not even save anything,- but look at it as I did after a while,- a working holiday where you can take your family along and enjoy the time off exploring the Middle East region, Oman is right next door and trips to Muscat and Oman I will always fondly remember.
When you get sick of it ,bailout as I did and go back to the real world get a proper job and work for a living.
