Hcezmas,
we have over 100 destinations, about 40 of them are 330/340 specific, about 15 both main fleet (B777) and airbus, and there are a few A380 routes.
The 330 fleet take most of the regional flying, and a lot of that is when the sun isn't up. The 340s have some Australia, some Europe, some Africa, some Far East.
The B777s have some Africa, lots of Australia, Most of Europe, most of the USA, all of South America, some Far East.
If you really want to know which equipment operates a specific route, download the timetable from the emirates.com website.
The above routings given can and does change regularly, the Marketing and Sceduling department is very pro-active, so will change the aircraft type on each route when necessary.
