The annual ranking was released by Skytrax, a UK-based consultancy that runs a yearly airline and airport review based on votes by international air travelers.
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.
Also according to the ACV, Da Nang International Airport has also been named among the top 10 improved airports in the world by Skytrax.
Earlier in August 2019, terminal T2 at the Da Nang International Airport was recognised for four-starred services by Skytrax.
