Southwest Airlines' Rapid Rewards program is their frequent flyer program, allowing customers to get free trips by earning points & redeeming them. The program offers unlimited reward seats - i.e., if a seat is available, customers may redeem their points for the seat.
There are no blackout dates in the program, and Rapid Rewards points never expire.
When taking a Southwest flight, the amount of the fare determines how many points are earned. Customers are also able to earn points with Southwest's Partners.
In addition, Southwest customers can earn more free benefits by applying and getting approved for the Southwest Airlines Rapid Rewards Credit Card (through Chase) and redeem points for international flights, hotel stays, car rentals, gift cards, cruises, and more.
