Asia has the world\u2019s best airports. Still. That\u2019s according to the latest ranking by Skytrax, which sees Singapore\u2019s Changi taking the top spot for the sixth year in a row. It\u2019s followed by Seoul\u2019s Incheon International Airport, Tokyo\u2019s Haneda, Hong Kong International Airport, and Doha\u2019s Hamad International Airport. Munich Airport, in sixth place, was the highest ranked among airfields in Europe. U.S. hubs were absent from the top 10 list based on an airport customer survey that\u2019s been conducted annually since 1999. Changi Airport - which handled a record 62.2 million passengers last year - has been expanding its capacity to meet rising demand for air travel. The airport is building its fifth terminal, a third runway, as well as a shopping-and-dining facility called the Jewel as passengers increase. At number 14, Vancouver was the highest ranked airport in North America. Denver, down one spot to 29th, was the best placed among U.S. airports, while New York\u2019s JFK fell six places to 69th. Asia also dominated Skytrax\u2019s list of the world\u2019s cleanest airports, led by Haneda, Nagoya in Japan, and Incheon. In a separate ranking of airport terminals, London Heathrow\u2019s terminal 2 placed first, followed by Munich\u2019s terminal 2 and Changi\u2019s terminal 3.
