AsiaWorld–Expo is an exhibition centre designed to host large scale trade fairs, exhibitions, conventions and concerts. It is located adjacent to Hong Kong International Airport. To better serve the travelling needs of exhibitors and visitors, the Airport Express was extended with a new station at AsiaWorld–Expo. The station opened on 20 December 2005, in time for the opening of the new exhibition centre on the same date. The extension provides rail access to the exhibition centre from the central business district and other stations on the MTR network. Its platform screen doors are different from on other stations of the Airport Express, as the screen doors are designed for the trains of Tung Chung Line as well, so those trains can also be used to run services from and to the station in order to increase passenger flow when large exhibitions or concerts are being held.
Sometimes, when large events are being held at AsiaWorld–Expo, some Tung Chung Line trains go onto the Airport Express track after Sunny Bay and terminate at this station. However, these Tung Chung Line trains do not stop at Airport.
