Southwest Rapid Rewards Visa is nice.
Use it on anything, and use it towards a southwest purchase and it doubles your credits.
Each dollar is worth 1 credit. (double if it is towards southwest purchase)
1200 credits is 1 point.
16 points for a free roundtrip flight to any Southwest destination.
When you sign up for Rapid Rewards Visa, you automatically get 8 points, and you get 2 points for creating a Rapid Rewards account on southwest.com. (10 points total)
This leaves only 6 points for your first free rountrip flight. Each one-way flight is 1 point.
Pretty badass IMO. I use it as a company card, and some of my coworkers have over 13 free roundtrip flights waiting to be used.
