Hartsfield-Jackson Atlanta International Airport (ATL) is one of the world's busiest airports, with tens of millions of passengers traveling through its terminals every year. Located south of downtown Atlanta, Georgia, the airport offers flights to 150 domestic and 75 international destinations, with an average of 2,700 arrivals and departures every day. The airport is expansive — the terminal complex covers more than 150 acres and has a total of 192 gates — so it can be overwhelming for both seasoned and first-time fliers. Because it's one of the world's busiest hubs, you'll want to arrive early to get through check-in and security lines and allow plenty of time for your layover (especially if you are traveling internationally). Whether you're at ATL for a layover or starting your journey here, we've rounded up the most important information to know before visiting the Atlanta airport, starting with an Atlanta airport map.
