Buffalo Niagara International Airport (BUF): Western New York's Commercial Air Hub
Buffalo Niagara International Airport serves as the primary commercial aviation gateway for Western New York and the Niagara Frontier region, handling approximately 5–6 million passengers annually from its location in Cheektowaga, just east of downtown Buffalo. The airport is owned and operated by the Niagara Frontier Transportation Authority (NFTA) and connects the Buffalo-Niagara Falls metropolitan area to major U.S. hubs and select seasonal destinations through carriers including Southwest Airlines, Delta Air Lines, American Airlines, United Airlines, JetBlue, and Spirit. BUF also benefits from proximity to the Canadian border — Niagara Falls, Ontario, is roughly 20 miles away — attracting cross-border travelers from the Hamilton-Toronto corridor seeking U.S. air fares.
Buffalo's terminal completed a major modernization in the early 2000s that unified the facility under a single roof with a new central concourse, and incremental gate and concourse improvements have continued since. The airport's two intersecting runways (10,200 feet on the primary 5/23) handle mainline narrowbody aircraft with ease. Southwest Airlines operates the largest presence at BUF, offering non-stop service to Florida, the Mid-Atlantic, Chicago, and Southwest's Texas hubs. Seasonal service expands BUF's direct route network to include leisure markets in the Carolinas and Caribbean. The airport's proximity to the Thruway interchange makes it equally accessible from Rochester to the east and Erie, Pennsylvania, to the southwest, giving BUF a catchment area well beyond Erie County.
What airlines operate at Buffalo Niagara International and which destinations do they serve?
Southwest Airlines is the dominant carrier, offering service to Baltimore/BWI, Chicago Midway, Orlando, Tampa, Fort Lauderdale, and other leisure and hub markets. Delta connects BUF to Atlanta (ATL) and Detroit (DTW) hubs. American flies to Philadelphia (PHL) and Charlotte (CLT). United serves Chicago O'Hare (ORD) and Washington Dulles (IAD). JetBlue offers Boston (BOS) and Fort Lauderdale service. Spirit provides ultra-low-cost options to select leisure markets.
How do I get from BUF to downtown Buffalo or Niagara Falls?
NFTA Metro Bus Route 24 provides public transit service between BUF and the Cheektowaga/Buffalo corridor. Taxi and rideshare services are available curbside. Niagara Falls is approximately 25 miles via I-190 North, typically a 30–40 minute drive. Downtown Buffalo is about 8 miles west on I-90.
Is there a Canadian preclearance facility at BUF for flights to Canada?
BUF does not currently operate Canadian CBSA preclearance. Passengers flying to Canadian destinations clear Canadian customs upon arrival. However, the airport sees significant reverse passenger flow — Canadians driving across the Peace Bridge or Rainbow Bridge to fly from BUF at U.S. fares, particularly for Southwest service not available from Hamilton or Toronto Pearson.
What parking options are available at Buffalo Niagara Airport?
BUF offers a connected parking ramp (short-term and long-term) directly adjacent to the terminal, as well as an economy surface lot with shuttle service. Daily rates in the ramp run approximately $20–$28; the economy lot runs $10–$14. Several off-airport lots on Genesee Street and Dick Road offer competitive rates with free shuttles.

Buffalo's Role as an Aviation Crossroads Between the U.S. and Canada
Buffalo Niagara International Airport's geographic position at the western edge of New York State gives it a dual identity: a regional hub for Western New York's 1.2 million residents and a destination airport for Canadian travelers from the Golden Horseshoe region of Ontario who cross the border for access to U.S.-based carriers, especially Southwest Airlines, which does not operate from Canadian airports. This Canadian leakage — estimated at tens of thousands of passengers annually — has been studied extensively by airport economists and represents a significant source of BUF's passenger volume that would disappear if Canadian low-cost options ever fully matured.
The NFTA has pursued long-term master planning at BUF that envisions expanded international charter service, cargo growth, and potential terminal expansion to meet projected post-pandemic demand recovery. The airport's economic impact on the Buffalo-Niagara region exceeds $2 billion annually when direct, indirect, and induced employment effects are included. Key industries relying on BUF's connectivity include the growing life sciences and biotech sector around the Buffalo Niagara Medical Campus, the UB and Canisius University academic networks, and the resurgent manufacturing and technology sector anchored by the Tesla Gigafactory in nearby Genesee County. For Western New York, BUF is not just a convenience — it is critical economic infrastructure.
