Singapore's Changi Airport has done it again. The world's 15th busiest airport secured the top spot as the world's best for 2017 in its fifth consecutive year.

Changi Airport remained undefeated during the Skytrax World Airport Awards held March 14 in Amsterdam. The ceremony based its results on millions of passenger surveys from all over the world. CEO Lee Seow Hiang of Changi Airport Group told CNN in a statement that winning the world's best airport in 2017 for the fifth year in a row boosts the "50,000-strong airport community at Changi Airport, every one of whom is passionate about delivering the most memorable airport experience" to their passengers.

The world's best airport for 2017 delivers a unique "Changi experience" that reflects Singapore's mentality. The amenities that make for a worthwhile stay at the airport include two round-the-clock movie theaters, a rooftop swimming pool, a butterfly garden, a napping lounge, toy stores, video arcades and kiddie playgrounds. More than 200 Changi Experience Agents also conduct surveys on the ground every day. "We know when things don't work," Ivan Tan, who works at Changi Airport's communications department, told Travel and Leisure.

Tokyo International Airport, also known as Haneda, nudged South Korea's Incheon International Airport from the second position after being voted as the world's cleanest airport. Munich Airport in Germany also dropped from last year's third best to this year's fourth spot. Hong Kong International Airport remained secure at number five. It bested Changi Airport with its dining experience.

Hamad International Airport in Doha, Qatar made an impressive leap from the 22nd spot in 2015 to last year's 10th best. It's now the world's sixth best airport for 2017. Germany's Frankfurt Airport made a surprise appearance on the list and replaced Kansai International Airport in Osaka from the 10th spot. North American airports remained a no-show to the top 10.
