browsing local forums as usual, saw a thread talking about CX's roadshow at IFC. When looking at the J seat, I found some difference with the J seat I sat onboard:

1. seems the seat has moved backward on upright position to increase shoulder room
2. seems the tray has moved forward so that the crew can serve sideways.

Not sure if my observations were right. Maybe fine photographic skills have contributed to these impression~
