Apparently the plane has changed to a 777XP. But not only is there no 8A,8B,8H,8J, there is also no 9A,9B! According to seatguru & SeatExpert there should be 9A,9B, but these don't exist either.
I just flew into SIN from NRT (landed a half hour early) and the plane was also switched to a 777XP. However, 9A/B
did exist so I was able to enjoy the great legroom afforded by this configuration.
