Singapore's famed Changi Airport has kept its title of 'World's Best Airport' for the fourth year in a row, the 2016 World Airport Awards revealed on Thursday.

Air transport research firm Skytrax, which conducts the annual World Airport Awards, picks its winner based on the number of votes sent in by travelers in what Skytrax calls the largest, global airport satisfaction survey.

"Changi Airport continues to innovate in both product and service options for its customers, and focus on making the customer experience at the airport as enjoyable and relaxing as possible," said Edward Plaisted, CEO of Skytrax.

Asian airports dominated Skytrax's list this year, taking six out of the top ten spots.

Coming in second was Incheon Airport in Seoul, followed by Munich Airport, Tokyo's Haneda Airport, Hong Kong International Airport, Nagoya's Chubu Centrair International Airport, Zurich Airport, London's Heathrow airport, Osaka's Kansai International Airport and Doha's Hamad International Airport.

Changi's many attractions makes it a tourist destination in itself, and is a source of pride for Singaporeans.

A movie theater, rooftop swimming pool, children's playgrounds, foot massage machines, and music bar lounges are just some of the amenities weary travelers can enjoy among the airport's three terminals.

Moreover, Changi is planning three major developments that it hopes will cement its title as world's best airport in the coming years.

Next year, the airport will launch a fourth passenger terminal designed to meet the operational needs of both full service and low cost carriers. Terminal 4 will increase handling capacity to 82 million passengers a year, from 66 million currently, Changi said in a statement on Thursday.

In 2019, a mixed-use complex is due to open. Called the 'Jewel Changi Airport,' the building will be designed by world renowned architect Moshe Safdie, featuring a glass and steel facade. It will house one of the largest indoor collections of plants in Singapore, a five-story garden filled with thousands of trees, and a 40-meter high indoor waterfall.

Lastly, a fifth terminal is scheduled for completion in the second half of the 2020s. Set to be one of the largest terminals in the world, according to Changi, it is expected to increase total capacity to 135 million passenger movements per year.
