CXorist,
Our 777 is limited to carrying just 40t from Oz east coast to the sandpit (14hrish). the 380 carries the full ZFW. So if we are carrying the full ZFW can you please explain how it is limited? This is why EK is swapping the ULR flights from the 777 to the 380. If you know something that EK flight ops don't, perhaps you should contact them and let them know.
