OK, Tosser Park...(Sorry, couldn't resist that one)...I have never worked for EK, but I have lived and worked in the Kingdom for 7 or so years...
Having visited Dubai and overnighted there over this time period, albiet 14 or so yrs ago, I feel if you have to be somewhere, Dubai would be somewhere around the top of my list...
Then add the newer A/C, payscale, and etc...You could do a lot worse...
Coming from an EU Low Cost situation, this would be 100% different...But you wouldn't be a pilot if you weren't looking for a little adventure...
I say if you have the opportunity, GO FOR IT!!!!!
Where's Mutt when one needs him???
