I have mixed feelings on that, at least from a Y's traveller's perspective. I like the the A330 in Y when travelling as a couple and you can get the pairs of seats, but the comfort of the A350 makes me ok to fly on that. The 6 way headrest is something CX needs to crow about much much more. I had the misfortune of flying with Etihad on their B787s recently and their silly fixed and only on one side headrest was awful. First time I used a neck pillow on long haul in ages. Thankfully they had reversed their ridiculous Y meal where people were complaining they were hungry. CX catering in Y is much more exciting and tasty (in almost all cases - on an 4 sector run, with 8 hot meals served, only one was an "ok", all the rest were tasty and good.)

Any chance the A350 (any variant!) will fly on the Heathrow run one day? Particularly the 9am departure? Would like to be able to take the A350 all the way to/from Oz without taking the B777.
