Your best bet would be to get a Credit Card with the same airline that you normally use for your travel. But only if you're sure that you'll continue to use that same airline no matter where you're going or what project you're on. For example, I almost always us US Airway. I also have the VISA US Airway credit card. So when I purchase airline tickets with my US Airway credit card, not only do I receive points on my US Airway frequent flyer account but I receive triple the number of points for using that credit card to purchase them. If you use Delta, then I'd suggest getting a Delta Visa or MC. They should also give you 25k or so extra points just for signing up to begin with. So first, decide what airline you're going to fly most of the time. Then go to their website and they'll probably have CC offers on there.
