I don't know if EK has any medium haul routes that are 1 daily A380? ULH they are more reluctant to do more than 1 daily flight but routes like NCL, where they can return in a day, multiple daily flights to improve connectivity are preferable, then they look at things like A380's on the busier flight. 2nd daily evening flight would be better for the Dubai market, Dubai arrival and departure times are much better than they are currently. Normally about an 08:00 arrival vs 00:00 currently and departures about 16:00 vs 07:00, so I think that flight would be much more attractive for Dubai bound passengers, as well as for some connections that require a 9+ hour wait at DXB the way flights are now
