I have the HKIA card - a frequent visitors card for express lane on arrival at HKG. It is a card issued by the HKG Airport.

I can use the same line as APEc card holders, but the card came through quickly- just send in the application, with a copy of your passport- and the pages showing at least 3 visits to HKG, through the airport in the last 12 months. At this stage there is no express lane on departure, though there was some hint that it would be coming some time in the future. It seems that there is never a long wait on departure in HKG for me though- but on arrival, it has been very helpful.

I only wish I had an APEC card for quick entry here in Korea- the lines at ICN are a nightmare- as a resident alien, I still can't use the Korean line...
