Of course i will choose Emirates if i were you . i was working with Flydubai and resigned only after 2 months , if i had the chance to work with Emirates i will do that without thinking. Emirates now is ruling the aviation industry and rabidly expanding not a low cost airline. Why you should accept flydubai when you can have the chance to join Emirates> u can take flydubai as a second option but never like first one. Best of luck.
