Members of frequent flyer schemes from over 30 airlines qualify for free membership in the Hong Kong government’s Frequent Visitor programme.

This lets you use the Frequent Visitor e-Channel – an automated immigration lane similar to Australia’s SmartGate system – at Hong Kong airport, as well as the Shenzhen Bay immigration checkpoint and ferry terminals for Macau and China.

Not every airline’s frequent flyer program enjoys the same fast track privileges, however, and for several such as Qantas it’s limited to top-tier Gold or Platinum status.
