Just be sure to cancel or change your flight before the flight boards to ensure your refund.

    What are Rapid Rewards?

    Rapid Rewards is Southwest's rewards program, where you earn points with every flight. While it's free to join, you have to be a very frequent flyer to earn enough points to redeem them for free flights. However, those flights have no blackout dates and your points never expire!

    If you sign up for the Southwest Airlines Visa, you earn 40,000 bonus points plus earn double the points on all Southwest purchases. Paired with their fair cancellation policy and free baggage check, this is all the more reason to fly Southwest.
