Biggest Airports in the US

The biggest airports in the US are the largest in terms of size.


The United States not only has the most airports, but it also boasts some of the world’s largest airports in terms of surface area.  

The United States is home to five of the world’s top 10 airports. However, some of the country’s largest airports are not necessarily the busiest.

The ten most significant airports in the US by surface area are listed below.

1. Denver International Airport – 137.26km

DIA is the biggest airport in the US and the world’s third-largest airport. It has the longest runway in North America, spanning 4.88 kilometers, and has a surface area of 135.7 square kilometers.

Its construction began in 1989 and was completed two years later, on February 28, 1995.  

Additionally, it cost $4.8 billion, nearly $2 billion more than the amount initially authorized for its development. DIA is North America’s fifth busiest airport. 

2. Dallas/Fort Worth International Airport, Texas (DFW) – 69.63km

Dallas Fort Worth International Airport

Dallas/Fort Worth is ranked second on this list, with a land area of around 70 square kilometers (27 square miles).

Furthermore, this airport, which is nearly half the size of Denver, has five terminals and 191 gates — and anyone who has visited DIA knows what a great experience it is! 

Moreover, The Skylink people mover system, which was installed as part of the modernization project, connects all terminals.

However, the airport served about 70 million passengers in 2017, ranking it the world’s 12th busiest airport. 

3. Orlando International Airport, Florida (MCO) – 54km

Orlando International Airport

It is only a half-hour drive from Walt Disney World and many other tourist attractions in this tourist-heavy area, so Orlando International Airport is a bustling place.  

MCO was founded in 1942 as McCoy US Air Force Base and converted to civilian use in 1976, covering approximately 54 square kilometers (21 square feet of space).  

Typically, the airport has two terminals and four concourses, with 129 gates. MCO receives approximately 50 million passengers each year, and the airport wants to develop another terminal shortly to accommodate the growing demand. 

4. Washington Dulles International Airport – 52.6km

Washington Dulles International Airport

Dulles Airport is 42 kilometers west of Washington, DC, in Virginia. It is considered the 4th biggest airport in the US. John Foster Dulles, the United States’ 52nd Secretary of State, is honored at the airport.  

The airport, which opened in 1962 and covers 52.6 square kilometers, is one of the largest in the country. Furthermore, it consists of the main terminal and two middle terminals, each with two concourses.  

United Airlines uses Concourses C and D exclusively, while international and domestic flights not handled by the company use the main terminal and concourses A and B.

In terms of passenger volume, Dulles Airport is the 29th busiest in North America.

George Bush International Airport

Houston’s George Bush Intercontinental Airport is 37 kilometers north of Huston. After Chicago’s O’Hare Airport, it’s United Airlines’ second-largest hub at 40.5 square kilometers.  

It is also Atlas Air’s hub. Although the land for the airport was purchased in 1957, it did not open until 1977 as Houston Intercontinental Airport.  

The airport was renamed George Bush in 1997 in honor of the United States’ 41st president.

IAH is the 14th busiest airport in the United States, and it was the first in North America to offer direct flights to every inhabited continent.

Salt Lake City International Airport

Outside of Salt Lake City, the SLC airport is around 12 square miles (31 square kilometers) in area. It’s also one of the country’s largest airports.  

Furthermore, this appealing airport is linked to the Utah Transit Authority’s TRAX system, allowing citizens to park outside the airport and travel in without having to pay hefty parking costs. 

However, with roughly 24 million passengers passing through each year, SLC is likely one of the most crowded airports on our top ten list.  

The airport, which opened in 1960, has lately undergone a series of improvements to guarantee that it can handle rapidly increasing traffic. 

7. O’Hare International Airport, Chicago – 30.9km

O'Hare International Airport

With its relatively central location in the Midwest, O’Hare International Airport is a popular airport with approximately 80 million travelers per year.  

Furthermore, O’Hare is nearly the same size as SLC but has just a quarter of the foot traffic, so you can imagine how crowded it may be.

Furthermore, ORD currently has seven runways, with the development of a new eighth runway expected to be completed soon.  

In addition, there are 191 gates in all, spread over four terminals. They’re collaborating with architects to figure out how to make future traffic flow better.
