Niagara Falls International Airport (IATA: IAG, ICAO: KIAG, FAA LID: IAG) is located 4 mi (6.4 km) east of downtown Niagara Falls, in the Town of Niagara in Niagara County, New York, United States.^[1] Owned and operated by the Niagara Frontier Transportation Authority, the airport is a joint civil-military airfield and shares its runways with the Niagara Falls Air Reserve Station. A new terminal building opened in 2009. It is notable for serving vastly more Canadian passengers from over the nearby border than Americans.

Niagara Falls International Airport opened in 1928 as a municipal airport with four crushed-stone runways.

During World War II, Bell Aircraft established a large manufacturing plant next to the airport, where during the war it built over 10,000 P-39 Airacobras and P-63 Kingcobras. Bell employed over 28,000 at the plant. After the war, the plant was the development site of the Bell X-1 used by Chuck Yeager to break the sound barrier in 1947.

The United States Army Air Forces assumed jurisdiction of the airport during the war, with the 3522d Army Air Force Base Unit managing the airport and coordinating use of the airfield with Bell Aircraft. The airfield was improved with macadam runways, 4000x150 (N/S), 4000x150 (NE/SW), 4200x300 (E/W), 4000x150 (NW/SE), and added many taxiways and other improvements to handle large numbers of aircraft. Air Technical Service Command also operated an aircraft modification center at the airport where new aircraft were given various updates prior to their deployment to operational bases and overseas combat theaters.

Civilian aviation operations and jurisdiction of the airport was returned in early 1946, and a joint-use agreement was made with the United States Air Force for Air Force Reserve and New York Air National Guard use of a portion of the airport.

Today, the Niagara Falls Air Reserve Station is home to the Air Force Reserve Command's 914th Air Refueling Wing (914 ARW), flying the KC-135R Stratotanker. The wing is operationally gained by the Air Mobility Command (AMC). The main runway was extended to over 9,000 feet (2,743 m) in 1959 to handle larger military aircraft, and was extended again in 2003 to its current length of 9,829 feet (2,996 m). For all practical purposes, the facility is a small Air Force base.

In November 2013 Calspan Air Services became the fixed-base operator for the airport, including refueling, ramp assistance, deicing, transportation and maintenance services.

On August 4, 2014, an Air France Boeing 747-428 flight AF356 from Paris Charles-de-Gaulle was diverted into the airport instead of landing in Toronto due to the temporary closing of Toronto Pearson International Airport. Landing and take-off were on Runway 28R.^[4] Niagara Falls gets a large number of Toronto's diversions due to its location and long runways.

The airport is in Class D airspace and has a FAA control tower.

The airport covers 1,067 acres (432 ha) and has three paved runways:^[1]

• 6/24: 5,189 x 150 ft (1,582 x 46 m), surface: asphalt
• 10L/28R: 9,829 x 150 ft (2,996 x 46 m), surface: asphalt/concrete
• 10R/28L: 3,973 x 75 ft (1,211 x 23 m), surface: asphalt

On September 2, 2009, Niagara Falls International Airport dedicated its new two-story terminal. With 69,430 square feet (6,450 m²), it has four gates (two jetways and two ground-loading gates), and has room for a Boeing 747 in size.^[15] The exterior is designed to reflect Niagara Falls' water flow. Cost was an estimated $42.5 million, $31.5 million for the terminal and $11 million for runway apron and landside improvements.^[16][17]

The previous (old) terminal is now occupied by the Niagara Aerospace Museum, also known as the Ira G. Ross Aerospace Museum.
