WTP Cabin: haven't flown it myself, but Mrs LostAntipod reports that the last row of WTP seats do not fully recline due to the cabin divider to the Y cabin. Quite annoying , as the seat in front ends up too close for comfort when reclined...when surely the point of paying extra for a WTP seat is to avoid this.

(Also the only lavatories WTP can use are the Y lavs at the rear of the plane)
