Buffalo Niagara International Airport (BUF) — Airport Guide 2026

🏢 One Terminal, Two Concourses

Buffalo Niagara International is refreshingly simple: a single terminal building split into Concourse A and Concourse B, with a shared central hall for check-in, security and baggage. Concourse A handles Air Canada, American, Delta, Frontier, JetBlue, Sun Country and United; Concourse B is effectively Southwest’s house. One security checkpoint, concourses connected airside. That’s the whole floor plan.

The airport sits in Cheektowaga off the Kensington Expressway (NY-33), about 11 miles east of downtown.

The 2026 operational note: in May, the FAA awarded BUF $8.7 million to replace up to eight passenger boarding bridges and install new ground-power and preconditioned-air units. The terminal footprint is unchanged — it’s the jet bridges and back-of-house being renewed. Expect a gate on rotation to be out of service during the work.

One genuine route development: JetBlue added a nonstop to San Juan in March 2026, a rare leisure-network addition at an airport whose business is overwhelmingly domestic point-to-point.

🛂 US Entry & the Canadian Cross-Border Reality

A domestic arrival at BUF involves no immigration — you walk off the plane into the concourse. The border applies only to the airport’s thin international layer, which in practice means Air Canada from Toronto plus seasonal and charter service. International arrivals are processed by US Customs and Border Protection (CBP); Global Entry members use the expedited kiosks where available; the free Mobile Passport Control app offers a faster lane for eligible travelers.

Visa-waiver nationals need an ESTA (~$21, valid up to two years) before boarding a US-bound flight. Canadians are largely visa-exempt for air arrivals and don’t file an ESTA.

The more operationally interesting border runs the other direction. BUF sits within easy driving distance of Ontario’s Golden Horseshoe — roughly 9.2 million people around the western end of Lake Ontario — and a substantial share of BUF’s passenger volume is Canadians who cross at the Peace Bridge or Rainbow Bridge specifically to fly from a US airport. If that’s you, the relevant formality is the land crossing on the way in: carry your passport, allow time for bridge queues at peak hours, and remember you’ll re-cross on the way home.

🚌 Getting to Downtown Buffalo and to Niagara Falls

Downtown Buffalo

NFTA Metro Route 24 (Genesee) runs downtown along Genesee Street in about 30–40 minutes for $2 one-way; the 24L Limited is the faster variant at roughly 30 minutes. Pay with the MetGo card or app. It’s a regular city bus, not an express coach — best when your destination is on or near Genesee and you’re not hauling oversized bags across town.

Uber, Lyft and taxis all serve BUF from the ground-transport curb. A ride downtown is short and unremarkable.

Niagara Falls (25 miles)

The Falls are 25 miles / about 33 minutes by car. Four options:

• Rental car — the cleanest choice on your own clock; Hertz, Avis, Budget and others operate at BUF.
• Taxi / shuttle — roughly $80–120 one-way by taxi; door-to-door shuttles also run the route.
• Direct bus — a scheduled bus links BUF to Niagara Falls USA, departing roughly every three hours and taking about 50 minutes. Cheap, but a three-hour headway means missing one bus costs you the whole plan.
• Rideshare — flexible on price and timing; the sensible middle option if you’re not renting a car.

🛋️ The Club Buffalo: BUF’s Only Lounge

BUF has one lounge: The Club Buffalo, located between Gates 6 and 7, open daily 4:00am to 7:00pm. It’s in the Priority Pass network, admits LoungeKey members and eligible credit-card lounge programs, and takes walk-up customers — check the current rate at the door. Inside: complimentary snacks and drinks, high-speed Wi-Fi, workstations, digital press.

There is no Delta Sky Club, Admirals Club or United Club at BUF. The Club is the entire lounge scene. If you’re flying Southwest out of Concourse B, check the distance from your departure gate first — the lounge sits on the gate 6/7 side, and a visit that eats into boarding time isn’t worth it.

🍗 What to Eat: Wings, Beef on Weck, and the Friday Fish Fry

Buffalo wings — fried, tossed in cayenne-and-butter hot sauce, served with celery and blue cheese — were, by the traditional account, created at the Anchor Bar in 1964. Duff’s is the other name locals will fight you over. Neither is at the airport; both are a short rideshare from downtown, and neither is approximated by airport concessions.

The city’s other signature is beef on weck: rare roast beef piled on a kummelweck roll (a kaiser crusted with coarse salt and caraway seeds), served with horseradish and a cup of jus. Less nationally famous than the wing, frequently the better meal. Round that out with sponge candy — a brittle, chocolate-coated local confection — and the Friday fish fry, a Western New York institution rooted in the region’s Catholic calendar, and you have the full Buffalo food map.

Airport concessions follow the flight banks; an early Southwest departure can pre-date the kitchens entirely. The regional food is a downtown errand.

💡 Insider: The Niagara Falls Layover — Honest Math

Niagara Falls is 25 miles from BUF, which sounds workable until the arithmetic runs:

Door-to-Falls is roughly 40–50 minutes each way once you include rideshare wait or rental-car pickup. At the Falls, allow a minimum of 60–90 minutes to reach Prospect Point and the brink at Niagara Falls State Park — the park itself is free; individual attractions like the Observation Tower and Maid of the Mist are priced separately. Add a 90-minute return-security buffer at BUF.

That puts the practical minimum at five to six hours, and a comfortable trip only at six-plus hours. With a 1–2 hour connection, the Falls are out; stay airside. With 3–4 hours, the Falls are still out, but downtown Buffalo is viable — Route 24 or a rideshare, enough time for wings and the waterfront at Canalside.

Two Buffalo sights reward a half-day layover: Frank Lloyd Wright’s Martin House complex on Jewett Parkway (timed tours; reserve ahead) and the Buffalo AKG Art Museum (the former Albright-Knox, reopened in 2023 after a major expansion).

If you’re overnighting between flights, the Falls become easy. Go in daylight; the view from the US side looks across the gorge to the more famous Canadian Horseshoe Falls. Crossing to the Canadian side is a separate international trip with its own border formalities — don’t fold it into a tight schedule.
