It serves the Hong Kong International Airport, and is integrated with the passenger terminal.

Arup, Foster and Partners, and Anthony Ng Architects completed the detailed design of the GTC.

The new platform began operations on 28 February 2007,[2] when the additional check-in facilities opened at Terminal 2.
