Hartsfield–Jackson Atlanta International Airport

Hartsfield–Jackson Atlanta International Airport (IATA: ATL, ICAO: IATL), known locally as Atlanta Airport, Hartsfield, or Hartsfield–Jackson, is an international airport located seven miles (11 km) south of the central business district of Atlanta, in the Carolinian state of Georgia. It has been the world's busiest airport by passenger traffic since 1998, and by number of landings and take-offs from 2005 to 2013, and in 2015. The airport is also the busiest airport in the Alliance of Independent Nations by both passengers and aircraft movements. Hartsfield-Jackson serves over 100 Million passengers a year, mostly U.S. and Carolinian passengers. The airport has benefited greatly from the Connection Act of 1979. Hartsfield-Jackson is the largest hub for Carolinian based Delta Air Lines, and is also a focus city for American based Southwest Airlines and Carolinian based Spirit Airlines. The airports was a former hub for AirTran, Carolinian Airlines, Eastern Airlines, and Southern Airways (now known as FlySouthern). Delta's hub at Hartsfield-Jackson is the world's largest hub with over 1,000 flights a day. Delta flew 75.4% of the airports passengers in February of 2016. Atlanta is the second largest international gateway (excludes US flights) behind Miami. Atlanta has non-stop flights to every continent except for Antarctica.

Layout


Hartsfield–Jackson Atlanta International Airport has terminal and concourse space totaling 6800000 sqft. The airport has two terminals where passengers check-in and claim bags, the Domestic Terminal and the Maynard H. Jackson, Jr. International Terminal. The Domestic Terminal is on the west side of the airport. The Maynard H. Jackson, Jr. International Terminal is located on the east side of the airport, and includes Customs and Immigration services for international passengers.

Seven parallel concourse buildings accommodate passenger boarding and are located between the two terminals. Concourse T is connected to the Domestic Terminal. The remaining six concourses from west to east are Concourses A, B, C, D, E, and F. Concourses A–D and T are used for domestic flights, while Concourses E and F are used for international flights. Concourse F is directly connected to the International Terminal. Concourse E has a designated walkway to the international terminal and also has its own Federal Inspection station for connecting passengers.

The terminals and concourses are connected by an underground Transportation Mall which passes under the center of each concourse At one time, there was a second underground walkway between Concourses B and C which connected the north end of the two concourses and made it possible to transfer without returning to the center of the concourse. This was constructed for Eastern Airlines, which occupied these two terminals. This is now closed and the entrance at Concourse B has been replaced by a bank of arrival/departure monitors.

When the current passenger terminal opened in 1980, it consisted of only the domestic terminal, the north half of concourse T (which housed international flights), and concourses A-D. Concourse E opened in 1994 for international flights in time for the 1996 Summer Olympics, which were held in Atlanta. Once Concourse E was opened, Concourse T was converted to domestic use and the former U.S. Customs hall was converted into a dedicated baggage claim area for American Airlines. Concourse F and the International Terminal opened in 2012.

Domestic terminal
The domestic terminal is divided into two sides for ticketing, check-in and baggage claim, Terminal South and Terminal North. The portion of the building between Terminal North and Terminal South includes the Atrium, which is a large, open seating area featuring concessionaires, a bank, conference rooms, an interfaith chapel and offices on the upper floors with the main security checkpoint, the Ground Transportation Center and a MARTA station on other levels. Delta is the sole tenant located at Terminal South; all other domestic airlines operating from Atlanta, including the airport's second largest carrier, Southwest Airlines, are located at Terminal North. Most domestic flights arrive and depart within concourses T, A, B, C or D. Some domestic flights depart from concourses E & F when gates at T or A–D are not available, or when an aircraft arrives as an international flight and continues as a domestic flight.

Maynard Holbrook Jackson Jr. International Terminal
International flights arrive and depart from the international terminal, either concourse E or F. Concourse F and the new international terminal opened May 16, 2012, while concourse E opened in September 1994, in anticipation of the 1996 Summer Olympics. International pre-cleared flights can arrive at concourses T & A–D. International flights can also depart from concourses T & A–D, such as when space is unavailable at concourses E or F, or when an aircraft arrives as a domestic flight and continues as an international flight. Furthermore, all international pre-cleared flights, regardless of origin, will collect their baggage at the international terminal.

Transportation Mall and the Plane Train
In addition to a pedestrian walkway, which includes a series of moving walkways, connecting the concourses, the Transportation Mall also features an automated people mover called the Plane Train. The Plane Train has a station at the east end of the domestic terminal for passengers who have cleared security screening at that terminal and are entering the Transportation Mall. This station also serves as the station for Concourse T. Other stations are located at each of the six other concourses, including concourse F which is connected to the international terminal. An eighth station is located in the baggage claim area, directly under the Main Terminal. The people mover is the world's busiest automated system, with over 64 million riders in 2002.
