Sign up for the Capital One Venture Rewards Visa Card and get 10,000 frequent flier miles when you spend $1000 in your first 3 months. There is a $0 intro annual fee for the first year, which bumps to $59 thereafter. This card was named Money Magazine's 'Best Rewards Card if you aim to rack up airline miles' because it earns 2 miles for every $1 spent, and miles don't expire. It also gives you an extended warranty on products purchased with the card.
