What is the busiest airport in the US based on passenger traffic?

Hartsfield-Jackson Atlanta International Airport holds the title of the busiest airport in the United States based on passenger traffic. A significant factor contributing to its status is its strategic geographical location as a major hub for domestic and international flights. Atlanta serves as a central connecting point for flights throughout the United States, which greatly increases its passenger numbers.

The airport's design and operational efficiency also play crucial roles. It has multiple runways and is equipped to handle a large volume of flights simultaneously. This enables Hartsfield-Jackson to manage both high passenger volumes and frequent departures and arrivals effectively.

Additionally, the strong presence of major airlines at Hartsfield-Jackson, particularly Delta Air Lines, facilitates connectivity to a wide range of destinations. This extensive network further cements its position as the busiest airport in terms of passenger traffic, making it a critical link in the aviation network of the United States and the world.
