Hartsfield–Jackson Atlanta International Airport

Hartsfield-Jackson International Airport (ATL) has been the busiest airport in the world since 1998, so it’s fitting that it comes in first on our list. Located just 10 miles from downtown Atlanta, ATL serves 150 US destinations and more than 75 international destinations in 50 countries. Because Atlanta is a two-hour flight from 80% of the US population, it’s a major connection hub. With two terminals, seven concourses and 209 gates, it might seem a bit overwhelming. Luckily, there’s a ‘Plane Train’ every two minutes to get you where you need to go. And almost 85% of flights from Hartsfield Atlanta leave on

Things to see and do

If you’re craving fresh air or traveling with your four-legged friend, there’s a 1,000-square-foot dog park in the Ground Transportation area. Not leaving the airport but you still want to connect with nature? Visit the virtual forest underground walkway between Concourses A and B. Here you can enjoy the sights and sounds of a peaceful grassy meadow under a canopy of trees. If you’re not the outdoorsy type, try renting a private room with a convertible sofa bed and a TV in Concourse B. With few canceled flights, a layover at ATL this holiday season won’t leave you stuck on the ground. Also, with the fourth-fastest free Wi-Fi you won’t waste time searching for hotels near Hartsfield-Jackson Atlanta Intl.

Shopping and dining

ATL is one of the busiest airports in the country, but in the unlikely event your holiday flight is delayed, there are lots of fun distractions. There are 26 bars and 23 coffee shops, 90 retail and convenience outlets and 3 duty-free stores.

Transportation

The Metropolitan Atlanta Rapid Transit Authority operates Atlanta's local public transportation system. Only 10 miles to downtown Atlanta, there are plenty of Atlanta airport car rentals if you’re in town for longer and want to explore the area.
