Noi Bai airport, about 35 km north of Hanoi's downtown, first gained a place on the list in 2016 when the second terminal was put into operation.

The airport has improved its management quality while increasing channels to receive passenger feedback through email, hotline, website, social media, and the eSmile platform.

It also provides passengers with free wifi and mobile phone charging outlets, along with enhancing its landscape and facilities.

According to Airports Corporation of Vietnam, Da Nang International Airport has also been named among the top 10 improved airports in the world by Skytrax./.
