Changi Airport handled 4.67 million passengers in June, 6.1 per cent more than in the same month last year.
Aircraft movements grew at the same pace with 28,300 take-offs and landings recorded, Changi Airport Group said on Tuesday.
Between January and June, total passenger traffic hit 26.2 million, a 5 per cent jump from the same six months in 2012.
The cargo business continued to slide in tandem with a global slowdown with total volumes down 1.8 per cent from a year ago to 150,500 tonnes.
For the half year, Changi handled 877,700 tonnes of air freight; down 2.3 per cent from last year.
