Introduction of Mc Carran International Airport
Harry Reid International Airport (IATA code: LAS, ICAO code: KLAS), known as McCarran International Airport before December 2021, is an international airport in Paradise, Nevada, serving the Las Vegas Valley, a metropolitan area in the U.S. state of Nevada, about 5 miles (8 kilometers) south of Downtown Las Vegas and is the main government airport for public use in the valley. Covering an area of 2,800 acres (11.3 square kilometers), it is the busiest airport in the United States that does not operate as a hub for any of the five U.S legacy carriers.
The airport was built in 1942 and opened to airline flights in 1948. It has expanded since then and has employed various innovative technologies, such as common-use facilities. There are two terminals at Harry Reid International and 5 concourses with a total of 92 gates. Terminal 1 was completed in 1963, Terminal 2 was completed in 1986, and Terminal 3 was completed in 2012. Prior to the completion of Terminal 3, Terminal 2 handled international flights. After Terminal 3 was completed, Terminal 2 became redundant, and it was demolished in 2016.
Currently, Terminal 1 has four concourses, each of which is connected to a central pre-security area. West of the pre-security area are the A Gates and the B Gates, two Y-shaped concourses with circular ends. To the south are the C Gates, accessed by the Green Line of the tram system. A satellite concourse housing the D gates opened in 1998. At the time of opening, the terminal housed a number of non-hub airlines. The Blue Line of the tram system links the D Gates with the post-security area. The terminal serves Allegiant Airlines, American Airlines, Delta Airlines, Spirit Airlines, and Southwest Airlines.
Terminal 3 was built on the eastern side of the Harry Reid International Airport Corridor, and is located just north of Concourse D. The terminal has 14 gates, seven domestic (E8–E12, E14–E15) and the other seven international (E1–E7); Concourse E and the D19-D26 "swing gates" at Concourse D (the part of Concourse D that is nearest to Concourse E) handle all international flights. Four of the international gates have two jetways each to allow for quicker handling of wide-body aircraft. The Red Line of the tram system links Terminal 3 with the D Gates.
