$256 with taxes in, for JetBlue is good, since it does not have bag fees. This equates to $206 with United. Portland is a great airport ... and it is common for Canadian's to fly out of there. At the Border, they will not bat an eye over a Canadian flying out of PWM, because it is so common. Jetblue has free snacks and some drinks, so the kids will have some "blue chips" or something on the flight. I like JetBlue. Also, let us know if you need some advice on a park and fly.
