16 Busiest Airports In The World [In 2021] | By Passenger Traffic

Civil aviation has evolved quite rapidly from just a few ex-military planes flying passengers over relatively short distances after the Second World War to a complex network of flight paths, dedicated protocols, and a growing number of regional and international airlines which is equally matched by the increasing number of passengers all over the world.

Air transportation is perhaps the most convenient medium of travel both in terms of time and safety. According to the World Bank open data, the total number of passengers transported in a year reached 3.9 billion in 2017, while the number of flight takeoffs reached 35.8 million.

Below, we have compiled 16 of the busiest airports in the world by passenger volume. The figures are provided by Airport Council International.
