Having flown EK in business class a few times over the last few years, I asked myself the question as per the title of this topic.
Whereas I consider the J hard-product on the A380 extremely good, I have the opinion the J hard-product on the 77W is much less comfortable.
This has nothing to do with the IFE, as the ICE system is the same on both (AFAIK). However, the seating is way different. The staggered seats on the 388 gives all pax direct aisle access, and also gives you quite a feel of privacy. On the 77W's however you find 2-3-2 seating, and although the seat itself is not bad at all - if you are unlucky you can end up in a middle seat. And no direct aisle access if you like to have a window seat.
The 388 also has the bar in the back, which is great to spend some time on a very long flight. Nothing like that on the 77W's.
Now that the 77W is the backbone of the EK fleet, and the 388 is to become a second backbone, wouldn't you expect a comparable product? Both types are used on longhaul flights, like to Aus/NZ and the US, so that should not be a factor.
Compared to other 77W operators with for example the herringbone or staggered seats I do consider the EK J class under par. As a passenger I therefore always try to get on the 388 if that is an option, and try to avoid the 77W.
I wonder if anybody shares my opinion. Also interested if anyone knows why EK has opted for these very different configurations.
Thinking of it, if I had to travel in Y it would probably result in the same conduct: avoid the 10 abreast seating on the 77W and instead go for 10 abreast seating on the 388. Must make quite a difference...
