Everything You Need To Know About Changi Airport's Cool New Terminal 4

Standing where the now-demolished Budget Terminal once was, T4 will have a handling capacity of 16 million passengers a year, two-thirds that of Terminal 3.

A total of nine airlines, including four airlines of AirAsia Group as well as Cathay Pacific and Korean Air will operate at the terminal.

T4 boasts a boutique design that aims to exude fun and vibrancy. It will also "push boundaries" with the innovative use of technology in its operations.

In building T4, several challenges were addressed, including making better use of a small space.

Ms Poh Li San, vice president of the Terminal 4 Programme Management Office, Changi Airport Group, said: "We looked at ways to make T4 more space-efficient, playing with height and (arrangement of facilities) to give a grand sense of space."

To illustrate the playing with dimensions, Ms Poh highlighted the lower check-in counters. There is also a centralised area for security screening.

"Also, with T4, we  wanted to push boundaries, break new grounds and use more innovative concepts to do things better and address the existing challenges in the current terminals," said Ms Poh.

Ahead of the T4 Open House taking place between August 7 and 20, the media was given a tour of the 225,000 sqm space on Monday.
