Almost exactly 14 years ago I heard TC say that he thought that by 2012 the smallest aircraft in the fleet would be the 773 and to use it on services really only needing something smaller is called 'the intelligent mis-use of capacity', where the company doesn't need all the effort and expense of a separate fleet of smaller types.
The 787 has a BIG order backlog that EK would surely be at the tail-end of if orders were placed now.
The 350 was red in the water for EK for ages before the plug was pulled.
Interesting, as there is a need to update and replace existing frames that the 350 would have addressed. Guess we'll have to wait and see.
