🏢 1. One Terminal, Two Concourses & the BUF Layout

Buffalo Niagara International is Upstate New York’s busiest airport, and it 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. You clear one security checkpoint and the concourses connect airside.

The airport sits in Cheektowaga, about 11 miles east of downtown Buffalo off the Kensington Expressway (NY-33). For 2026 the operative fact is modernization money: in May 2026 the FAA awarded BUF $8.7 million to replace up to eight passenger boarding bridges and install new ground-power and preconditioned-air units, part of a broader NFTA upgrade program. None of it changes the building’s footprint — it’s the jet bridges and the back-of-house that are being renewed — but expect a gate or two to be out of service on rotation.

One route note worth having: JetBlue added a nonstop to San Juan in March 2026, a rare bit of leisure-network growth at an airport whose business is overwhelmingly domestic point-to-point.

🛂 2. US Entry, CBP & the Canadian Cross-Border Reality

A domestic arrival at BUF involves no immigration — you walk off the plane into the concourse. The border only applies 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). Members of Global Entry use the expedited kiosks on arrival where available; the free Mobile Passport Control app offers a faster lane for eligible travelers; everyone else sees an officer. To board a US-bound flight, visa-waiver nationals need an ESTA (~$21, valid up to two years) and visa-required nationalities need a US visa. Canadians are largely visa-exempt and do not file an ESTA for air arrivals.

The defining BUF fact, though, runs the other direction across the border. BUF sits within an easy drive of Ontario’s Golden Horseshoe — roughly 9.2 million people around the western end of Lake Ontario — and a large share of its passengers are Canadians who cross at the Peace Bridge or Rainbow Bridge to fly out of a US airport, where fares are often markedly lower than from Toronto Pearson. If you’re one of them, the relevant border is the land crossing on the way in, not anything at the terminal: carry your passport, build in time for the bridge queue at peak hours, and remember you’ll re-cross on the way home.

🚌 3. Getting to Downtown Buffalo and to Niagara Falls

Downtown Buffalo — NFTA Metro Route 24 (Genesee). The public option costs $2 one-way and runs along Genesee Street to downtown in about 30–40 minutes; the 24L Limited is the faster variant at roughly 30 minutes. Pay with the MetGo card or app. It’s a normal city bus, not an express coach, so it’s best when your destination is on or near Genesee and you’re not hauling much.

Rideshare and taxi. Uber, Lyft and taxis all serve BUF from the ground-transport curb. A ride downtown is short; a ride to Niagara Falls is not cheap (see below).

Niagara Falls — the headline trip. The Falls are 25 miles / about 33 minutes by car. Your options:

• Rental car — the cleanest way to do it on your own clock; the major firms (Hertz, Avis, Budget and others) operate at BUF.
• Taxi / shuttle — roughly $80–120 one-way by taxi; door-to-door shuttles also run.
• Direct bus — a scheduled bus links BUF to Niagara Falls USA, departing roughly every three hours and taking about 50 minutes. Cheap, but the three-hour headway is the catch — miss one and the next is a long wait.

The trap to avoid: an unmarked driver at arrivals quoting a “special” flat rate to the Falls. With metered rideshare and a published shuttle and bus network, you never need to accept a curb-side negotiation.

🛋️ 4. The Club Buffalo: BUF’s One Lounge

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

There is no Delta Sky Club, American Admirals Club or United Club at BUF — The Club is the whole lounge scene. If you’re flying Southwest out of Concourse B, factor in the walk: the lounge sits on the gate-6/7 side, so confirm it’s a sensible distance from your departure gate before committing to a pre-flight visit.

🍗 5. What to Eat: Wings, Beef on Weck & the Friday Fish Fry

Buffalo is the city the wing is named after, so the regional table is non-negotiable. 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, but both are a short ride from downtown.

The city’s other signature is beef on weck: rare roast beef piled on a kummelweck roll (a kaiser crusted with salt and caraway), served with horseradish and a cup of jus. Add 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 Buffalo food map.

Inside the terminal, concessions run to local and national names; hours follow the flight banks, so an early Southwest departure can pre-date the kitchens. If wings are the goal, they’re a downtown errand, not a gate-side one.

💡 6. Insider: The Niagara Falls Layover — Does It Work?

BUF is one of the few US airports where the layover question has a genuinely interesting answer, because one of the natural wonders of the continent is 25 miles away. But the honest math is stricter than the distance suggests.

The numbers. Door-to-Falls is ~33 minutes by car each way — call it 40–50 minutes each way once you add rideshare wait or rental-car pickup. At the Falls, you want a minimum of 60–90 minutes to walk to Prospect Point and the brink at Niagara Falls State Park (the US side; the park itself is free, individual attractions like the Observation Tower and Maid of the Mist are extra). Then reverse the trip, and add a 90-minute return-security buffer at BUF.

The verdict. This is a 5-to-6-hour-layover trip, minimum — and comfortably so only at 6+ hours. With a standard 1–2 hour connection, you will not see the Falls; don’t try. If your layover is in the 3–4 hour band, the Falls are out, but downtown Buffalo is in reach on Route 24 or a short rideshare — enough for wings and a look at the waterfront at Canalside. Two Buffalo sights reward even a half-day: 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, and from the US side the view is 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 connection.
