I will be meeting somebody who is arriving in Hong Kong and taking the airport express from the airport. Understand there are two arrival halls, A and B, at the airport, so it may be confusing to meet there. Does anyone know if there is only one entrance leading to where you take the Airport Express? Or are there separate or multiple entrances, depending on which arrival hall you come from?
I thought it may be a good idea to arrange to meet at the Airport Express entrance or the platform itself, if there is only one main walkway there.
