At the terminal, double confirm that you will have the baby carrier assigned to you if you want to get bullhead seats.

If you get bullhead seats without the baby carrier assignment then you will have a super painful ride.

it's up to 20lb, but i can't remember.

I don't mean that you need to put the baby on it. the issue is that it is entirely possible that other babies are assigned to the carriers while your baby is not.  so imagine, you are holding on your baby while the baby carrier is occupied.  your baby will be only 6 inches away from the carrier.

The centre isle has 4 seats, 2 baby carriers.  last time when I went back to HK, we had 4 adults, 3 babies in the centre isle.

that was the messiest ride I ever had.
