Interesting article. For me, the width of the seat at 18.5 inch fine but it's the separation between me and my seat mate that is much more important. It looks like PS seats accomplish that. Have two flights coming up on the A350, one in PS and one in D1. Will be interesting to experience both. I suspect that PS to be a big upgrade from C+ but the "suites" might even be a downgrade over the herringbone 777 D1 seats. It looks little different from the 767 D1 seats with sliding doors added.
