The Biggest and Busiest Airports in the US in 2021

 

Although the ongoing COVID-19 pandemic has wreaked havoc on the global airline industry over the past year and a half, airports across the United States continue to see millions of passengers pass through their doors every month. That being said, though, COVID-19 has reshuffled the rankings for which airport is the biggest and busiest in the nation.

Let’s take a look at the top 10 busiest and largest airports in the United States and explore what makes them such influential travel hubs for not just the US but the entire world. We should state ahead of time that these rankings were compiled based on the total number of passengers transported through each airport, not the number of flights.
