Buffalo Niagara International Airport — Buffalo, United States

Buffalo Niagara International Airport serves Buffalo, New York, and the surrounding western New York region close to the Canadian border and Niagara Falls. Coded BUF, the field's elevation reaches 728 feet, and two runways support a steady mix of domestic flights to major hubs and leisure routes tied to tourism at nearby Niagara Falls. Many Canadian travelers from the Toronto area cross the border specifically to fly out of BUF, drawn by generally lower fares than flying from major Canadian airports. The airport has seen renewed investment in recent years, including terminal upgrades aimed at accommodating growing passenger numbers. As western New York's main commercial airport, BUF plays a key role connecting Buffalo's economy and the Niagara Falls tourist corridor to the wider national air travel network, and its cargo facilities also support regional manufacturers shipping goods across the border. Direct flights also reach several Florida destinations during the winter travel season, reflecting steady leisure demand.
