Sorry, the bit about Y+ was unrelateld to the premium seats in Y. I was just noting that the seat map for those particular flights do not hint at there being the new Y+ cabin installed.

But regarding the 'premium' seats in Y, I sort of guessed that they would be for full fares and elites. But the Cathay website does say that you can indeed pay 100 USD to pay for exit rows - so I can only assume that anyone can pay for 'premium' seats.

Does anyone know whether the three rows of twin seats at the back can be paid for? For example BA will allow you to pay various fees to choose any seat in advance, and you can do it online. But it looks like CX aren't promoting any paid-for seating in the same way.
