Although I don't share the blunt views of BS, what all pilots flying into DXB must understand is that DESDI or BUBIN are the only inbound points for both Sharjah and Dubai (add to that Jebel Ali now). We at ACC are given a flow rate by APP (10,15,20nm's etc.) to which we must comply and sequence traffic accordingly.
It DOESN"T MATTER to which airport you are flying, DESDI or BUBIN is the "common rwy" on which you all must "land".
Sometimes, when workload permits, we may coordinate parallel tracks inbound, but this is the exception, which has now become expected.
