CX,
We have been told that the fleet will number between 260 and 280 by 2020 (depending on who is quoted). I thinks its 190ish now. Seems EK is restricted to this fleet size because DXB can't handle anything more than that. Once the move to DWC (dunno when that happens but they say 2225ish) they want to grow to 460ish. All the 330/340 are on the way out now. The classic 777s start being put to pasture next year, and the first 773ER leaves in 2017.
