Hartsfield-Jackson Atlanta International Airport (IATA: ATL, ICAO: KATL) is located in the Atlanta, Georgia, USA metropolitan area, and is the busiest airport in the world both in terms of number of passengers as well as the number of takeoffs and landings, surpassing Chicago's O'Hare International Airport. It accommodated 980,197 takeoffs and landings in 2005, and handled 88.4 million passengers according to projections. Many of these flights are domestic flights from within the United States where Atlanta serves as a major transfer point for flights to and from smaller East Coast cities. As such, it has been the subject of an old joke that states that it doesn't matter where one will go in the afterlife, they will transfer through Atlanta to get there. As an international gateway to the United States Hartsfield-Jackson ranks seventh; JFK International in New York City is first.[1]
