Niagara Falls International Airport — Niagara Falls, United States

IAG serves Niagara Falls International Airport, located in Niagara Falls, New York, near the famous waterfalls that draw millions of tourists annually to the U.S.-Canada border region. The airport shares its runway infrastructure with the adjacent Niagara Falls Air Reserve Station, giving it a dual civilian-military character. Commercial service at IAG has fluctuated over the years, often supplemented by low-cost carriers targeting travelers who also use the airport as an alternative to the busier Buffalo Niagara International Airport nearby. Beyond tourism traffic tied to the falls, IAG supports Air Force Reserve operations and occasional cargo activity. Its proximity to the Canadian border also makes it a convenient option for travelers on the American side seeking easier access to the falls.
