I suppose being AA platinum ( One World whatever gemstone ) wouldn't help, although in Europe it seems to get you into the One World lounges on day of flight - even arrival day.</font>
The fundamental problem at HKG is that there is a very clear separation of arriving and departing passengers - there is no mixing once you are airside of security. All of the airline lounges are airside. The only way to get to the departures level is to have a boarding card for flight onwards on that day.
KA has a separate departure lounge, but it is not in the same league as the Wing.
