I just got back from DXB this morning. All I can say is that you'd better enjoy traffic and heat. 110 degrees and somehow it was still humid!!
my brother was at the interview with you. he loved it, hes praying for the job. i would think that hands down emirates will give you a better quality of life, if you dont mind living outside the US. They treat you like a professional but yea its a huge sacrifice to go to dubai.
