More concerning security
I have wondered about inbound/outbound passenger segregation for a while and this seems like a good thread to resurrect.
Some airports, like Hong Kong, Bangkok, Auckland and Vancouver (airports I am familiar with), strictly segregate inbound and outbound passengers, whereas others like Heathrow and Changi, for example, do not.
Does anyone have any idea why the differences?
Concerning security screening, I've notice that Bangkok has now dropped outbound screening near the gate areas in favour of screening immediately after immigration, presumably for speed and cost saving.
