This will not be a balanced opinion, just mine:
I had similar hours to you and left a good airline to come to EK.
If I knew then what I know now I would have never had come anywhere near the place. I was guilty of seeing what I wanted to see and not what was actually there, fuelled by the slick
PR & recruitment process.
Since I've joined the T & Cs have been changed to the detriment of F/Os in favour of DECs: they can do anything without the threat of recourse. The training system is a mess. Pay has stood virtually still while the $s slide has meant a net drop in pay of nearly 25%...despite what they call 'exchange rate protection' which doesn't come close to protecting the shortfall. We fly more hours (majority at night) and are away from base longer (allowances are poor and are calculated with discounts provided from hotels taken out before you get them).
Professional satisfaction has been replaced with professional frustration as there is little or no respect or trust between the management and flight deck crews which in turn has led to very low morale generally.
With your hours and experience I would personally suggest that if you are intent on coming to the region you consider Etihad. They are the start-up 'national carrier' and have billions behind them backed by the UAEs President. You would have higher relative seniority and hence a command opportunity should come quicker. Their pay is better, 30% if rumours are to be believed, and the management seem a great deal more able than the ones we've had to deal with recently. You could still live in Dubai if you so wish but it is a building site at the moment with a great deal of strain on resources such as schools and accomodation.
It is a hard decision to make but there is a great deal more info available than there was when I jumped...and remember when you jump it is extremely difficult to climb back. Once you ship your life down here it will cost a lot to reverse the process so do your homework well.
At the end of the day it is all relative. To many the job at EK is a great deal better than they had elsewhere. There are other opportunities here also where some are making a living away from the company with other businesses and have never had it so good but they only serve to distort the picture when you only consider EK as a career in isolation.
From a purely personal, European & flying career perspective though I believe that this was a bad move.
Good luck with any decision you make.
