PY is offerred on selected routes and sometimes not sold to public as a PY product but the plane is still configed with them and selectable to jal elites anytime but OW emerald members can request on check in to be allocated a PY seat which is what I did. Whilst in my case I didn't receive the PY service and amenities...... Who cares as it's the seat which makes all the difference. FYI i was flying on the haneda to hong kong route. The seat is somewhat bigger than Y seat and perfect size for anyone over 6 foot. I'm not a big fan of the shell with the sliding down recline(probably more specific word for this). I only noticed the reading light when I was leaving. Power source and foot rest are nice but the extra leg room makes this totally worth it especially if it's just a mere 10k miles to upgrade. I am sure the extra amenities and service make it even more worth it. Highly recommended! I'll upload some photos when I get back to a computer.
