It depends on which airline u are taking, u can call them for details. If u are taking CX, the weight limit for baby bassinet is 15kg or below and the baby is under 24 months. I think 15m usually will not sit on his own, so u hold him with a extra sit belt is better. And if u take business class, I think the seat is wide enough for u and ur baby sit together after take off, so can save the money for bb ticket la!
你諗住去邊?係咪同家人一齊去?國泰而家有舊椅同新椅。the old seat is forward facing and u can see the pax beside u. The new seat has a high partition and u cannot see the one beside u and is 斜斜地. But the seat is still wide enough for u and baby together. The new seat can even lay flat so the bassinet is no need too la!
