Which is the largest airport in the world? Is this a question that has ever crossed your mind as you’ve sprinted across point A to B in a crowded airport?

According to the Transportation Security Administration (TSA), more than 771 million people passed through American airports in 2017.

During the last couple of years, airports have been getting busier. In particular, from 2016 to 2017, airports witnessed passenger traffic increase by 6.6 percent.
