After staying in a Canadian hotel in Niagara Falls, ON, what is the best transport to BUF airport in NY?

How much time should be allowed for customs clearance at the border crossing into the US from Niagara Falls, ON on way to BUF airport?

Figure up to an hour to be on the safe side. If you are without a car, the best way to the Buffalo Airport from Niagara Falls, Ontario would be by bus, either Trentway-Wagar or one of the Trailways-Greyhound pool runs,some of which can drop you off at the Buffalo Airport enroute to Rochester and points east. Be sure to ask the t icket agent and/or the driver before you board the bus as to whether that particular schedule is due to stop at the airport enroute to Batavia and Rochester. Otherwise, figure on a taxi from the downtown bus terminal in Buffalo to the airport. Toward Buffalo, the Greyhound schedule calls for a 15 minute layover at the Border, but it can and often runs as much as an hour, depending on passengers aboard the bus and how slow Customs is at clearing the bus and its occupants. This is particularly true if there are passengers from certain Middle Eastern countries aboard and these could hold up the bus for an hour or more.

5-0 Taxi (Niagara Falls, ON main taxi service) will take you from your hotel directly to the airport for approximately $75 CAD. Ask your hotel front desk staff to make the arrangements.
