I wonder if when you say During the summer, flights between Buffalo (the closest city to Niagara) and New York City can be expensive you're aware that JetBlue has brought the fares down, for competing airlines as well as itself. I'm seeing fares in the $100 round trip range available even for the July 4 weekend. As usual it's best to book a fare like this well in advance, as soon as one is able to commit.
