"Yes they do have policies regarding stopovers , however unless it impacts the dubai layover i dont see how it can be related (maybe EK experts can answer"

From memory usually if there is a stop over there is usually additional tax to pay so I guess question is do you have the same duration in Dubai? There is also limits on sime tickets for number of stop overs but again unless we know the specifics of the what is supposed to have been breached, its hard to say
