What is The Biggest Airport in the World? (The Top 10)

March 26, 2022
Lee Ferrara

As airline travel continues its meteoric growth, there is a never-ending demand for bigger airports. Here is the biggest airport in the world...plus the top 10.

Airline travel grows a staggering rate every year...and as of 2020, it's been valued at almost $700 Billion. Growth had been impressive before the Coronavirus Pandemic that sparked fear in air travelers and airlines alike...prompting worldwide shutdowns. The International Air Transport Association (IATA) was predicting 8.2 billion passengers to partake in air travel by 2037.

The rise in air travel has had a dramatic effect on the development of airports around the world, and shows no signs of slowing down. These huge centers of aviation are being constructed all over the world to try and accommodate for how many people are flying each day and each year.

This growth rate forces cities that want their airport business must come up with ways to keep these travelers happy or risk losing them altogether if they don't provide ample space for expansion...and comfortable travel.

With all this advancement, many people want to know just how big the biggest airports really are (as well the world's busiest airports) worldwide, and how many fly out of them.

Check out our deep-dive post below: The Top 10 biggest and busiest airports in the world by geographical size...

(NOTE: We've also compiled a list of the 100 busiest airports in the United States here, so take a look.)

[IDEA: Add airport maps as the image for each]

1. Beijing Daxing International Airport (PKX)

It's actually hard to fathom just how big China's newest jewel, Beijing Daxing Airport really is. Beijing Daxing International Airport, the biggest airport in the world, covers a land area of over 18 square miles, not the largest in terms of land (keep reading), but its single terminal totals a mammoth 7.5 MILLION square feet!

It cost an estimated $11 billion (US) to build and you'll have to walk over a quarter mile from the center of the terminal to the furthest gate in each wing, of which it has five.

It has over 70 food and drink stops/restaurants, and hosts a varied menu with mostly a Chinese flair.

The airport has 4 commercial runways and 1 military runway. It is built to manage 300 departures and landings an hour, and even though it doesn't handle the most passenger traffic (yet), it is expect to do just that by 2030. 

2. King Fahd International Airport (DMM)

King Fahd International Airport, the second busiest, is located roughly 20 miles northwest of the city of Dammam in Saudi Arabia. It is named after the former King of Saudi Arabia, Fahd ibn Abdulaziz...and the airport is also known as Dammam International.

Dammam was the largest airport in the world at 3.5 million square feet until it was unseated by the above Beijing Daxing International. However, it is easily the largest airport by property size coming in 300 square miles!

King Fahd International opened in 1999 and was previously used as a U.S. air base in the Gulf War

DMM has 2 runways that are 2.5 miles long each and 38 airlines operate out of of the field.

3. Denver International Airport (DEN)

Denver International Airport (DEN) opened in 1995 replacing Stapleton International, that had serviced Denver since 1929.

It is the largest airport in land area in North America at 52 square miles, second worldwide only to King Fahd International in Saudi Arabia.

DEN has 6 runways, with Runway 16R/34L being the longest commercial use runway in North America at 16,000 feet in length.

DEN serves as a major hub for United Airlines and also serves 22 other airlines. It employs over 35,000 people making it the largest employer in the state of Colorado.
