Hi, we will be stopping off in HK for a couple of hours en route from UK to Sydney. I’m planning to take empty water bottles to fill once we clear security in the UK ... what will happen in HK? Will the water need to be emptied on the plane/in the terminal? Not sure if we will have to go through security again in HK. I’d rather take “proper” bottles that we can refill however don’t want to risk them being taken off us, so wondering if it’s better to just buy disposable bottles of water at each airport? We’re flying with Cathay Pacific if that makes any difference. Thanks.
