Japan ANA Platinum card members (same level) can enjoy free access to ANA lounges for two people (you can freely use all Star Alliance lounges worldwide. I'm just using Japan ANA as an example.) Of course, you can also get free access for two people to Hong Kong's Star Alliance lounges. There are other benefits too, such as one additional checked baggage allowance, free advance seat selection, priority boarding, priority baggage handling, and access to priority security lanes at airports, saving you time. Whether you're traveling for shopping or relocating overseas, having one extra checked bag (23kgs/32kgs) can save you money.
