As one of the world’s busiest airports by international passenger and cargo traffic, it has been rated as the ‘World’s Best Airport’ by Skytrax several times, and is the first airport in the world to hold the accolade for eight consecutive years. It has also been rated as one of the world’s cleanest airports and highly rated international transit airports.

The airport is located within its namesake district of Changi, at the eastern end of Singapore, approximately 24 kilometres east from Singapore’s Downtown Core at the Central Region on a 25-square-kilometre site.

Changi Airport serves more than 100 airlines flying to 400 cities in around 100 countries and territories worldwide, as of November 2020. About 7,400 flights arrive or depart at Changi each week, or one every 80 seconds.

With Singapore’s strategic location being a favourable destination for high demand layovers, the airport also serves as a focus city for Qantas, as well as the flagship cargo hub for FedEx Express in Asia.

The airport has won over 620 awards since its opening, including 28 “Best Airport” awards in 2019 alone. Changi Airport’s efforts to mitigate the effects of ageing infrastructure include continual physical upgrades to its existing terminals and building new facilities to maintain its high standards in airport service quality.
