These Are the 10 Busiest Airports in the World
In a typical year, hubs across Europe, Asia, and the United States see millions of passengers, with airports in Dubai, London, Paris, and Tokyo named among the busiest in the world. Of course, 2020 was not a typical year, and air traffic dropped dramatically due to the coronavirus pandemic. According to Airports Council International (ACI), overall passenger traffic decreased by 64.6% at the world's airports. Air travel has rebounded at varying rates across the globe as travel restrictions are lifted, but according to ACI's 2020 world airport traffic rankings, the top 10 busiest airports were all in the United States and China.
If you're planning to travel through one of these major hubs, there are a few things to keep in mind. For example, you'll want to give yourself plenty of time to check your bags, get through security, and find your gate. And if you must stop at a busy airport for a layover, don't go for flights with short connection times - it can take a while to travel between terminals. Traveling through a super-busy airport can be a headache, but they do have some perks - larger airports typically have a longer list of amenities, including great lounges and places to eat or drink.
