The airport location plays a great role in being the major hub for the world's largest airlines, making it one of the busiest airports in the world. 

It has the highest number of passengers even though the city of Atlanta has just over 500,000 population. Here is why, the state and the local community support each other in attracting Aviation companies. 

The airport is located in a metropolitan area with more than 6 million population which has an effect on how busy it is. Another important reason is that it is the main airport hub for Delta Air Lines. 

SkyTeam's founding member and the US legacy carrier use this airport as their main hub. It is the busiest airport regarding aircraft movements, landing, and takeoff.

IATA code: DFW


During the peak of the COVID-19 pandemic, there was an even more surge in the population of passengers in this airport. 

This is because there was low demand for flights, and for this, demand was reduced. However, passengers have to pass through airports like Dallas-Fort Worth, which brings about a surge in passengers. 

With this, it is still operating more flights than any other place on the planet minus the ATL. Right now, the airport is operating more flights making it second on the list of the busiest airports in the world in 2024.

One of the reasons this airport ranks among the top 10 busiest airports in the world in 2024 is because of the fact that it was the largest station for three main carriers. 

Another driving force for being on the top list was the increasingly large demand for leisure travel and tremendous desire for travel to locations with access to wide-open regions where people can socially distance or isolate themself. 

The location of DEN is favorable as well as 60% of the United States passengers at this airport is connecting to flight.
