Airports flying high
Some airports rank highest for passenger volume, such as Hartsfield-Jackson Atlanta International, which served close to 94 million travelers last year. Others excel in passenger satisfaction in North America, such as those in Detroit and Minneapolis, which triumphed in a new study by J.D. Power. A few lead the way when it comes to innovation, such as Singapore’s showstopper Changi Airport, which is about to introduce automated immigration clearance, meaning passengers can transit through it passport-free.

However, there are three international airports that punch above their weight when it comes to their rich array of connecting flights around the world.

London Heathrow is No. 1, according to a new report by aviation data firm OAG, followed by New York’s JFK and Amsterdam’s Schiphol. World-class cities need world-class airports after all, and the top five is rounded out by two Asian megahubs: Kuala Lumpur International and Tokyo Haneda.
