Buffalo Niagara International Airport
KBUF is the ICAO code for Buffalo Niagara International Airport (IATA BUF), located in Buffalo, NY.
Buffalo's commercial and private aviation hub, 8 miles east of downtown Buffalo and 20 miles from Niagara Falls, with U.S. Customs on-site for cross-border traffic.
Airport guide
Buffalo Niagara International is a large commercial airport that handles private aviation alongside scheduled carriers. The FBO ramp is separate from the terminal, so arriving by private jet means bypassing the main terminal entirely. Million Air operates the primary FBO on the field with full fuel, ground handling, and crew amenities.
The airport has no slot restrictions and no hard curfew, though noise abatement procedures apply late night and early morning. Operations run around the clock. U.S. Customs and Border Protection is available on-site, which matters significantly here: KBUF handles substantial cross-border traffic from Toronto and southern Ontario, and many private passengers originate or continue into Canada from this airport.
BUF sits in western New York with year-round service. Winter operations are routine here, and the airport is well-equipped for ice and snow conditions. If your itinerary involves Niagara Falls, Toronto, or the wine country around the Finger Lakes, KBUF is the practical hub.
Getting there
Downtown Buffalo is 8 miles west of the airport, a 15 to 20 minute drive without traffic. Niagara Falls (U.S. side) is about 20 miles north, roughly 25 minutes. The Canadian side of Niagara Falls is around 25 miles, but customs crossing times at the Peace Bridge or Rainbow Bridge vary widely and can add 30 to 60 minutes.
Toronto is approximately 95 miles from KBUF, but the Peace Bridge border crossing makes door-to-door times unpredictable. Under light conditions the drive runs about 1.5 hours; during peak hours or with commercial truck backups at the bridge, 2.5 to 3 hours is realistic. Car services operate from the FBO. For Toronto-bound passengers with flexible timing, the border crossing condition on the day is the main variable to track.
