The number of Southwest Rapid Rewards points needed for a free flight varies based on the cash price of the ticket and the fare type. Typically, you will need anywhere from about 6,000 to 30,000 points for a free one-way flight, depending on factors such as the destination, travel date, and fare class (e.g., Wanna Get Away, Anytime, Business Select)

. Southwest uses a revenue-based points system, so the points required fluctuate with the ticket price. For example, a $100 cash ticket generally costs less than 7,500 Rapid Rewards points plus taxes and fees

. There are no blackout dates or capacity controls for award flights, so if a flight is available for purchase with cash, it can also be booked with points

. Points can also be combined with cash through the Cash + Points option to reduce the number of points needed

. In summary:

• Points needed for a free flight: roughly 6,000 to 30,000 points one-way
• Points required depend on cash fare price and fare type
• No blackout dates; award seats available whenever cash seats are
• Cash + Points option available for partial point redemption

This makes Southwest Rapid Rewards points flexible and relatively easy to redeem for free flights
