What Are the Busiest Airports in the United States?

As you could likely tell from the list of the biggest airports in the United States, the largest airports in US are not always the busiest ones. The busiest airport in the US is actually Hartsfield-Jackson Atlanta International Airport. The Hartsfield-Jackson Atlanta International Airport had roughly 103.9 million passengers in 2019. The primary reason that this airport is the busiest one in the US is that its favorable geographic location makes it an ideal connection hub. Interestingly, despite how busy this airport is, Hartsfield-Jackson Atlanta International Airport has been voted the most efficient airport in the world for 18 years in a row.

Los Angeles International Airport is the second-busiest airport in the US. One of the reasons for this is that LAX, as it is commonly known, serves as the gateway to Los Angeles, California. LAX receives plenty of passenger traffic from overseas. Los Angeles International Airport received roughly 84.5 million passengers in 2019.

The O'Hare International Airport in Chicago is the third-busiest airport in the United States.
