Jetblue does have limited airports they use, however if they are going where you need to go they will ALWAYS go there for a cheaper price. One time I got to the airport earlier than I needed to be and they said that they had an earlier flight if I wanted to go on that one with out paying anything extra. The flight that they offered us was actually a more expensive flight which is why I choose the later flight and they also gave us the extra leg room seats. I would say that this is really a company that goes the extra mile for it's customers.
