Guys thanks for all your comments
It really helps a lot getting this kind of factual information. Specially the one given by TJ who is in a similar situation.
As I mentioned before I lived in Doha for 5 years and is very similar but always heard Dubai was more expensive, therefore wanted to make sure I can make it there.
As well I was living in a 5 BR Villa and 2 new cars... Perhaps now will be a bit more conservative.
Regards and fly safe.
By the way the command upgrade time is 18 months from release on line or 18 months from now in your case? Does it make a difference if you have previous experience? Such as A320 hours and around 3300 on B737.
