Regarding the 340-500, it depends which airline you fly with.
Were you in Y on EK? They put 8 across for ultra long flights, whereas SQ run all business class, with 4 across, so it depends on how the airline chooses to cram you in.
I recently had the very unpleasant experience of being the middle of 5 on a 777, fortunately on a 1 hour domestic flight, but the memory makes me cringe, even now ;-)
