Buffalo is served by Buffalo Niagara International Airport (BUF), a major airport in Western New York and a key gateway to the Niagara region. It receives strong domestic connectivity from major hubs and popular leisure destinations, with a notable presence of low-cost carriers providing competitive fares. For travelers heading to the Niagara Falls area, BUF is often the most convenient and affordable option on the US side.
The most important arrival routes into Buffalo come from major airline hubs, including New York City (LGA, JFK, EWR), Chicago (ORD), Atlanta (ATL), Charlotte (CLT), and Detroit (DTW). Buffalo also receives direct flights from popular sun destinations like Orlando (MCO), Fort Lauderdale (FLL), Tampa (TPA), and Las Vegas (LAS), as well as seasonal services from other cities like Phoenix and Myrtle Beach. These leisure routes are often very competitive, especially from Florida.
Buffalo Niagara is a focus city for Southwest Airlines and JetBlue Airways, both of which operate many routes into BUF and drive down fares through aggressive pricing. The airport is also served by all major network carriers: Delta (from Atlanta, Detroit, Minneapolis), American (from Charlotte, Chicago, Dallas), and United (from Chicago, Newark, Denver). Low-cost carriers Frontier Airlines and Allegiant Air provide additional competition on leisure routes, especially from Florida and Las Vegas. This mix means that on popular routes like New York–Buffalo or Orlando–Buffalo, you can often find fares under $100 round-trip if you book at the right time.
To find cheap flights to Buffalo, book domestic arrivals 3–6 weeks in advance. For leisure destinations (e.g., from Orlando, Tampa, Las Vegas), book Southwest, JetBlue, Frontier, or Allegiant flights 2–3 months ahead for the best deals. Use flight comparison tools and set price alerts. Flying into Buffalo on weekdays (Tuesday–Thursday) is typically cheaper than weekends. Buffalo is known for particularly good fares from Florida, New York City, and Chicago. For international travelers coming from outside the US, the most common strategy is to fly into a major hub like New York (JFK), Chicago (ORD), or Atlanta (ATL) first, then catch a domestic flight to BUF. Alternatively, consider flying into Toronto Pearson (YYZ) — about a 2-hour drive from Buffalo — which sometimes has cheaper international fares from Europe or Asia, though you'll need to factor in border crossing and ground transport. Southwest and JetBlue's presence at BUF often provides the best value with transparent pricing (no surprises on bags).
