The Capital One Venture card is one of the best cards out there if you want to earn airline miles. You get two points per dollar, and can then redeem them for flights (as well as other things) at the rate of 1 cent/point. I.e. a $500.00 plane ticket costs you 50,000 points. This is different from most other airline credit cards, whose award-miles-per-flight rates vary wildly depending on demand. For example, even though the jetBlue credit card gives you 1 point/dollar, it turns out that when you redeem points for some flights, each point can be worth as little as 0.75 cents/point.
