Hartsfield Atlanta International Airport representatives boast that Hartsfield is currently the busiest airport in the world. During flight delays or in-between flights travelers can enjoy themselves in the 225,000-square-foot, three-story atrium that is part of the terminal building. The atrium is covered with a 75-foot-wide glass dome, which soars 40 feet above the floor. Bring your camera.
Figure out how much free time you will have. Check to see whether your flight is late and whether it will arrive/depart in Concourse A, B, C, D, E or T.
Sit underneath the dome, and relax while you decide what you want to do in the atrium.
Consider dining at any of a variety of eateries or, if it is the afternoon, listening to a pianist on the main floor of the atrium.
Shop at the specialty stores, but keep in mind that you may have to check in or mail larger purchases (see Warnings, below).
People-watch.
Visit the interfaith chapel on the main level.
Dine instead, or again, at any of numerous eateries in the concourses. You will need to take the "people-mover" (see Tips, below).
