Atlanta has always been a crossroads—open to new ideas, and the new arrivals who came to this lush, hot, rolling land when the city rose as a railroad terminus. Today, it is a transportation hub still, with Hartsfield–Jackson Atlanta International Airport one of the busiest airports in the world, with 80% of the U.S. population residing within a two-hour flight. It’s why the city ranks #4 for Airport Connectivity among all U.S. cities. Atlanta, like most optimized hubs, also boasts efficient, inexpensive, direct public transit links to the city from its airport. It is also a long-time business titan and ranks #9 in the nation for most Fortune 500 Companies based in town.
