This new strategy is being adopted in order to lower charges to the airlines. The plans of adding the commercial space would be spread over the next two years. This expansion would increase the shopping and restaurant areas by 5%.

At the moment, the revenues received by the 123 restaurants and other commercial outlets located in the public areas across all four terminals exceed $100 million a year, adding up to a total of about 10% of total sales throughout the airport.

Lim Peck Hoon, executive vice-president overseeing commercial operations for the Changi Airport Group, stated that taking the retail revenue to a higher level requires more commercial space and it was a priority. With the help of this additional revenue, the airport hopes to bring about changes in the landing, parking and other aeronautical charges levied on airlines.
