"With summer travel season underway, you're likely to pass through Hartsfield-Jackson Atlanta International Airport — the world's busiest airport — which often serves as the first welcoming place for visitors to Atlanta. Its prominence reflects Atlanta's growth since Delta Air Lines blossomed in the 1960s and more businesses set up in the area, contributing to the region's population boom and making Hartsfield-Jackson a major hub for travelers." - Eater Staff
