Charleston International Airport (IATA: CHS, ICAO: KCHS, FAA LID: CHS) is a joint civil-military airport located in North Charleston, South Carolina, United States. The airport is operated by the Charleston County Aviation Authority under a joint-use agreement with Joint Base Charleston.^[3] It is South Carolina's busiest airport; in 2023 the airport served over 6.1 million passengers in its busiest year on record.^[4] The airport is located in North Charleston and is approximately 12 miles (19 km) northwest of downtown Charleston. The airport serves as a focus city for Breeze Airways. It is also home to the Boeing facility that assembles the 787 Dreamliner.^[5]

In 1928, the Charleston Airport Corporation was founded and purchased 700 acres (280 ha) of land previously belonging to a mining company. Although privately developed at first, the City of Charleston floated bonds in 1931 to acquire a portion of the site for passenger service. Within ten years, three runways were paved and outfitted with lighting for nighttime operations. In World War II, control of the airfield passed to the United States Army though civilian service was allowed to continue to use the airfield. After the war, the airfield reverted to civilian use for a short time. In 1949, a new passenger terminal was built.

During the Korean War, the airfield was reactivated for military use and in 1952, the City of Charleston and the United States Air Force reached an agreement on control of the base and the runways—an arrangement that has been renegotiated over time and that continues to this day. In 1979, the civilian portions of the airport were transferred from the City of Charleston to the Charleston County Aviation Authority, which had operated two other airports in the area. The current terminal on the south end of the airport was built in the 1980s on land acquired by Georgia Pacific.^[6]

In October 2009, Boeing announced that it would build a major plant on 265 acres (107 ha) at the airport as a second final assembly site for its 787 Dreamliner commercial aircraft. The facility began limited operations in July 2011 and rolled out its first completed aircraft in April 2012. Additional facilities to complement aircraft assembly have since been announced by the company.^[5]

Since 2010, the airport's passenger figures have doubled.^[7] New services established by additional airlines during this time along with increased services from the three legacy carriers have contributed to this growth.^{[citation needed]}

In 2021, the newly established Breeze Airways announced that the airport would serve as a focus city for the airline and announced service to 11 cities.^{[citation needed]} In 2022, the airport authority announced a 20-year master plan for future growth of the airport, including the constructing of an additional concourse, adding up to 11 new gates, providing additional plane stands, and expanding parking facilities for vehicles.^[8]

The airport has had brief periods of international service. In 2001, Air Canada briefly served the airport from Toronto but ended service immediately after the September 11th attacks. Porter Airlines briefly served Charleston with flights to Toronto in 2015. In April 2019, British Airways launched a seasonal route to London's Heathrow Airport using a Boeing 787. This was Charleston's first scheduled transatlantic flight. The first season ended in October.^[9][10] Due to the COVID-19 pandemic, the service never returned.^[11] In 2023, Air Canada announced a return to Charleston with daily nonstop flights to Toronto beginning in March 2024. ^[12][13]

The airport consists of four general areas: the military area to the west, the airline terminal to the south, the general aviation area to the east, and the Boeing assembly area further to the south. The combined airport area of Charleston International Airport and Charleston Air Force Base covers 2,060 acres (830 ha) and has two runways: 15/33, 9,001 ft × 200 ft (2,744 m × 61 m) and 03/21, 7,000 ft × 150 ft (2,134 m × 46 m).^[2][14]

For the 12-month period ending May 31, 2019, the airport had 118,211 aircraft operations, an average of 324 per day: 42% commercial, 28% general aviation, 16% military, and 13% air taxi.^[2][1] In May 2019, there were 81 aircraft based at this airport: 28 single-engine, 6 multi-engine, 43 jet, and 4 helicopter.^[2]

Joint Base Charleston owns and operates the runways at the airport and has an agreement with the Charleston County Aviation Authority to allow civilian use of the field. General aviation services are operated by the Charleston County Aviation Authority. Boeing South Carolina operates the Boeing assembly area.
