One of the best things I ever did was get a JetBlue by AmEx card. I don't know if you fly a lot, but I fly back and forth from home to school about once a month for various reasons, and JB offers a great fare and nonstop flight from BOS-RDU. So I got the card, and in less than a year, had earned a free flight to anywhere JetBlue flies. They don't pull any BS about getting your points, and you earn miles by either flying with them, or paying your bill. And if you get a JB card, your points never expire! I love it.
