Sign up for a Southwest Airlines Rapid Rewards Plus Card and make your first purchase to get 25,000 bonus points. That's $400 in Wanna Get Away Fares--enough for a free roundtrip flight. You also earn 2 points for every $1 you spend with Southwest Airlines, 2 points for every $1 spent with Southwest Rapid Rewards Hotel and Car Rental partners, and 1 point for every $1 you spend on everything else. Plus, you get 3,000 points every year on your cardmember anniversary. A $69 annual fee applies and points can take 6-8 weeks to credit to your account.
