Travelers often assume one of New York City's major airports—LaGuardia (LGA), Newark (EWR), or JFK—offers the best access to Niagara Falls. In reality, all three sit roughly 400 miles away, translating to a 6–7 hour drive or a connecting flight plus ground transport. The true gateway is much closer and far more convenient.
Located just 25 miles (about 40 kilometers) from Niagara Falls' city center, BUF is the closest major airport by a wide margin. The drive takes roughly 35–45 minutes via I-190 North, crossing Grand Island for a scenic approach. Most major U.S. carriers serve BUF with frequent flights from hubs like Chicago, Atlanta, Detroit, Charlotte, and New York-area airports.
For international travelers or those with Star Alliance/OneWorld loyalty, Toronto Pearson sits about 80 miles (1.5–2 hours) from the falls. It offers vastly more global connections but requires a longer drive and border crossing. Only consider YYZ if BUF lacks your needed route or carrier.
Bottom line: For Niagara Falls, fly into Buffalo (BUF). It's the closest, most practical, and usually most economical choice—saving you hours better spent experiencing the falls themselves.
