Buffalo Niagara International Airport opened as Buffalo Municipal Airport in 1926 on former farmland, making it one of the country's oldest public airports. The original airport included a small terminal building, one hangar, and four cinder runways, each 3,000 feet (910 m) long by 100 feet (30 m) wide.

Yes, Buffalo Niagara International Airport (BUF) is the single, primary commercial airport serving the Buffalo, New York, and Southern Ontario region. While people often refer to it simply as "Buffalo Airport," the full official name is Buffalo Niagara International Airport. It is located in Cheektowaga, about 11 miles east of downtown Buffalo. You should not confuse it with the much smaller Niagara Falls International Airport (IAG), which is located about 20 miles away in Niagara Falls and primarily handles low-cost domestic carriers like Allegiant and Spirit. For almost all major airline travel (Delta, American, United, Southwest, JetBlue), you will be flying into BUF. In 2026, it remains a popular hub for Canadian travelers who cross the border to take advantage of lower U.S. domestic fares to destinations like Florida and Las Vegas.
