Last time I was in Dubai (November 2012) there were plenty of EK flights to regional destinations, so they seem to be managing quite well. If EK need a different aircraft type for some services they would be buying it, buying aircraft doesn't seem to be a problem for them.
The Government of Dubai has basically desided to let all the 737/A320s flights out of Dubai that they run in the hands of FlyDubai
What I am suggesting is that FlyDubai becomes a subsidery of The Emirates Group and increases ties with EK
Would it be a good idea?
