Airports are the most often used gateways between countries for travellers who begin their flight trip. Aviation hubs offer infrastructure for planes, manage immigration and cargo, and serve as a destination for thousands of tourists each year. Over the years, ever-increasing passenger numbers have resulted in many congested airports. Due to the difficulty of cramming all passengers into one facility and parking all aircraft in one location, governments began expanding their aviation hubs with additional terminals and runways.
The following are the world’s biggest airports, each of which can handle thousands of passengers and land hundreds of aircraft daily. Take a look at the list of the world’s top ten biggest airports by area in 2021.

A single terminal serves Daxing Airport. However, the terminal is the world’s biggest single-building terminal, with five concourses appearing like a starfish from the sky. The “starfish” airport is equipped with four runways.
Orlando International Airport (MCO) is 50.9 square kilometres in size.
This airport began commercial operations in 1981. The Orlando International Airport serves as a critical hub for JetBlue (JBLU), Southwest Airlines (LUV), and Spirit Airlines (S64) (SAVE).

It is the biggest airport in the United States of America in terms of size and contains the country’s longest runway, a public runway. It is not one of the busiest airports in the United States, much alone the world, in terms of passenger volume. It is often regarded as one of the country’s best-managed airports. Several airlines have a hub at the DIA, also known. Among them are PenAir, Frontier Airlines, and United Airlines.
The King Fahd International Airport (DMM) covers an area of 776 square kilometres.
In 1999, King Fahd International Airport, commonly known as Dammam Airport, began operations. Saudia, SaudiGulf Airlines, and Flynas all use the airport as a hub. There is no other airport in the world that is larger in land area than King Fahd International Airport. It is enormous. However, commercial activities at an airport of this size are ill-advised. Indeed, this airport was not closed to commercial travel until two decades ago. It serves as a hub for a few airlines, including Saudia and SaudiGulf Airlines. Land area, in general, is a secondary statistic for airports. The most engaging data is passenger traffic, cargo traffic, and aircraft mobility at an airport. However, the land area might sometimes provide information about the metrics stated above and nothing else.
