I don't normally think much of these deals, but Southwest is really good at letting you use points for free tickets on almost any flight. (most airlines are way too restrictive) Here is the info.
Apply for the Southwest Airlines Rapid Rewards® Premier Card1 and we'll get you started with 50,000 bonus points after your first purchase2 - that's over $800 in Wanna Get Away® Fares that can be redeemed for 2 FREE ROUNDTRIP FLIGHTS!
You'll also receive 6,000 bonus points every year on your Cardmember Anniversary, which can be redeemed for a $100 Wanna Get Away® Fare - covering your $99 annual fee. Start planning your trip to one of the 70+ destinations Southwest Airlines serves.
