The Top 100 Busiest Airports in the US (2019-2020)

July 22, 2021
Kenneth Holland

Flying in the United States (as well as the world) has become a staple of life and everyone needs to fly from time-to-time. In this deep-dive data article, we're going to look at some of the busiest airports in the US, including some revealing and sobering airport stats for the year 2020.

The number of domestic passengers varies immensely between airports, with some airports serving millions more than others. The US is home to three out of the ten busiest in the world in 2020.

As most know, 2020 was an extraordinary year. With the Pandemic, all industries the world over were deeply affected, and air travel was hit maybe the worst off all. In 2020, the majority of airports saw an over 90 percent DECREASE in passenger numbers in the hardest hit months of The Pandemic compared to any other year.

People often ask us the question: 'What is the busiest passenger airport in the US?'

Read below to find out...the 100 busiest airports in the US:

(NOTE: Total passenger traffic by month (for top 10) and year (for top 100) is ranked by 2019 statistics. 2020 ranking (we feel) is skewed due to extraordinary and highly unusual criteria (The Pandemic).

Statistics were compiled by individual airports' reporting and the U.S. Bureau of Transportation Statistics.
