After the last few months of travels, I think I now have enough experience with AY A350 J to really judge it..Only one thing to say..an utter and epic fail, period.
I would take BA A380 (or 777/747) any day over AY A350 in J. I don't care about coach the least, no experience/no comments. The AY seats are simply horrible and too tight cabin layout..for example not enough toilets vs. pax.
During last few days I had many legs with CX who has same seat but the more expensive version of it..quite a difference and makes AY A350 J feel more like Y+ in comparison.
Sad to say but overall (not only the new A350s) AY LH J is nowhere compared to past years. Great crew can still make it feel pleasant, but that is it. Sad but true.
