Is there any way to know in advance which posts of transfer security will be open at a certain time? I can’t find any info in the HKIA app and the few last times I went through transfers in HK I found that only the two located near arrivals and the one at the top of the peer by gate 35 were open, the three of them with interminable lines. The rest (by gates 44, 62 and 27) were always closed.

Thanks!
