EK recently stated that they wll use most of their 380s on routes to the UK (LHR and LGW)...
the rest will be deployed on more profitable routes such as HKG, SYD, SIN etc.
The upper deck of the 380s will be F and J class only....and the new concourse at DXB has a top floor dedicated to serving these passengers.
Their 2 class 380s will be for the south asian routes, but they will not be in sevice any time soon.
