Yes, the row numbering already caused confusion on one of the flights on this new product I took last Saturday but to be fair the suites do have the numbers in big friendly lit fashion (as in David's pictures and great report) I think people just need to get used to it. Yes it's confusing but doesn't take long even for a blind guy like me to figure out
the seats themselves I found really comfortable and nice. I personally think the 2A/K, 4A/K pairs are best for solo pax as more privacy with the ledge/table aisle side, but that's just me.
As noted couples (or companions, business folks, whatever) travelling together it's not so idea, but then I'd say seats like 3A/4D, 3K/4E as they are closer with both aisle facing
I really liked the product and think it's a big step forward to QF.
the CX seats yes are very nice true and until QF's fleet is configured fully CX would be a consistent option, but I would say this product is up there with the CX seat.
