Bangor International Airport

Bangor International Airport (IATA: BGR, ICAO: KBGR, FAA LID: BGR) is a joint civil-military public airport on the west side of the city of Bangor, in Penobscot County, Maine, United States. Owned and operated by the City of Bangor, the airport has a single runway measuring 11,440 by 200 ft (3,487 by 61 m). Originally a military installation known as Dow Air Force Base, Bangor remains the home of the 101st refueling wing of the Maine Air National Guard. Most Air Force operations at the base ceased in the 1960s. Covering 2,079 acres (841 ha) the airport is categorized by the Federal Aviation Administration's (FAA) National Plan of Integrated Airport Systems (2023–2027) as a non-hub primary commercial service facility.

The airport's location on major air corridors between Europe and the East Coast of the United States make it a common spot for diverted flights, as well as military charter flights.

Bangor International is operated as an "enterprise fund", which means that the expense of operating it comes from airport revenue. Revenues are generated by air service operations, resident aviation-related industrial companies, real estate, cargo, international charter flights, and corporate/general aviation traffic. One of three international airports in the state, it serves the residents of central, eastern, and northern Maine, as well as parts of Canada.

It was designated by NASA as an emergency landing site for the Space Shuttle.
