17 Busiest Airports In The World [In 2024] | By Passenger Traffic

Civil aviation has come a long way from just a few one-time military planes carrying passengers over relatively short distances during the First World War to a multitude of private and public airlines operating in a complex network of flight paths and protocols in the modern era.

Air transportation has gradually evolved to become the most convenient medium of travel both in terms of time and safety. According to the World Bank open data, the number of passengers carried by air transport reached an all-time high of 4.3 billion in 2019, while the number of flight takeoffs reached 38.9 million.

The place where passengers board and get off from airplanes is called an airport or aerodrome. An airport features at least one runway, one operational control tower, hangers, and a tower. Larger airports have extended facilities with a larger landing area for aircraft, taxiways, more sophisticated air traffic control towers, passenger service facilities, such as lounges, restaurants, and shops.

Below, we have compiled a list of the 17 busiest airports in the world by total passenger served. The figured are provided by Airport Council International.

Note: As compared to 2019, drastic changes have been recorded in 2020’s list of busiest airports in the world. It is due to the worldwide lockdowns, disrupting the entire airline industry. The list shows a sudden shift in passenger traffic from the Western countries to China. Out of 17 of the busiest airports on this list, ten are located in China, in contrast to only four (including Hong Kong International Airport) the previous year.
