Free flights are back! Sign up for a Southwest Airlines Rapid Rewards Premier Card and get 50,000 bonus points when you spend $2,000 in 3 months, matching the last time we saw this in November. That will get you over $800 in Wanna Get Away Fares, which is enough for 2 free round-trip flights. You earn 2 points per $1 you spend with Southwest Airlines, Southwest Rapid Rewards Hotel and Car Rental partners, and 1 point per $1 you spend on everything else. You can also use your points on international flights through Southwest's More Rewards program (plus, this card has no foreign transaction fee). There's a $99 annual fee, but every year you get 6,000 bonus points on your cardholder anniversary, which is worth around $100 towards airfare.
