The top 10 largest airports in the world in 2021
The airports are the most common gateway to get from one country to another, for those who begin their air journey. The aviation hubs provide the infrastructure for the aircraft, handle immigration issues, cargo and also accommodate thousands of travelers every year.
Over the years, constantly growing passenger numbers made many airports too overcrowded. Since it has become difficult to squeeze in all the travelers into one building and park all the airplanes into one place, countries started to enlarge their aviation hubs with new terminals and runways.
Here are the largest airports that can accommodate thousands of travelers and land hundreds of airplanes daily. Take a look at the list of the top 10 largest airports in 2021, in terms of their area size.
