The Atlanta airport operates its own on-site parking area. According to the airport parking services website, it offers hourly and daily parking rates. There are courtesy vans to help drivers if there's an emergency with their vehicles. An economy courtesy shuttle transports drivers from the north and south parking lots to the airport.
Several independent companies have off-site parking areas near the Atlanta airport. They provide transportation to the airport from their parking lots, and the daily fees are lower than on-site parking. Park N Fly has three parking areas near the airport. The Parking Spot has two parking lots near the airport.
At high traffic times like the holidays, all of the airport parking options can become overcrowded. The private parking companies allow you to reserve a spot to park your car. Drivers can also check on the airport website to see if the on-site parking lots are open or full.
