Remember a few weeks back when Southwest began offering double credit for flights from Baltimore to Boston? Well, the airline is now offering the same double or nothing fun on flights throughout its system. So you can earn extra points on travel to any city Southwest serves.
You have to sign up for Rapid Rewards and register for the promotion before booking your flight. You'll also need to travel by May 26. With the bonus points, you'll be able to earn a free roundtrip flight after taking four roundtrips - that's in half the number it usually takes. If you purchase Business Select seats, you'll earn the free trip even quicker. And remember, free doesn't mean free - you'll still need to pay government fees just like on everything else.
