SINGAPORE - Changi Airport has posted a YouTube video on its FansOfChangi channel on Tuesday to show people what the future Terminal 4 will look like.

Dubbing it "A Terminal For The Future", the two and half minute show highlights new technology such as the extensive use of self-service check-in and bag tagging machines.

A sneak peek is also given into the arrival and departure areas as well as a central shopping galleria.

T4, which is being built where the former Budget Terminal was located, will open in 2017. Cathay Pacific is the first carrier to confirm its interest in using the new facility.
