This also marked a 4% rise from the number of passengers recorded in the second quarter of 2019, before the Covid pandemic.
China was Changi Airport's largest market in the second quarter by passenger traffic, followed by Indonesia, Malaysia, Australia, and India, according to figures published on the airport's website.
Changi Airport was named the world's best airport in a survey by The Telegraph last year, outperforming more than 60 other contenders.
In April, it reclaimed the tiltle as world's best airport for 2025 at the World Airport Awards organized by London-based aviation consultancy Skytrax after losing the title to Qatar's Hamad International Airport last year.
Renowned for its cutting-edge facilities, Changi offers automated check-ins and biometric authentication to enhance immigration processes. It recently became one of the first airports globally to introduce passport-free immigration clearance across all terminals, enabling travelers to clear immigration in as little time as 10 seconds.
