I don't think you are going to be able to fly from Bufalo direct to Santo Domingo with Jet Blue. In the fine print it says that all flights from Bufalo, Syracuse, and other places are through NYC-JFK. That probably means you take a flight from Bufalo to NYC and then from NYC down to SDQ. I could be wrong, but review the fine print in their web site to further inquire on this.
