Aircraft landings and takeoffs also grew by 5.3% to 28,460 on the corresponding month a year ago.
On the cargo front, 155,100 tonnes of airfreight were processed last month, 4.9% higher than a year before.
Changi registered a total of 14.3 million passenger traffic movements during the July-September 2015 quarter, a growth of 5.8% compared to the corresponding quarter last year.
Boosted by an increase in passengers travelling with low-cost carriers following a period of depressed demand, this also represents the highest ever traffic Changi has achieved in a quarter.
For the quarter, traffic was positive for nine of Changi Airport’s top 10 country markets with China registering the strongest growth of 14.9% on-year.
However, passenger movements between Singapore and Indonesia declined 0.4% even as Indonesia remained Changi’s top market for the period, followed by Malaysia, China, Australia and Thailand.
In the first nine months of 2015, 40.9 million passengers travelled through the airport, 2.1% more than the same period a year ago.
