The most direct and popular way to transfer points into the Southwest Airlines Rapid Rewards program is through the Chase Ultimate Rewards ecosystem. If you hold a premium Chase card like the Sapphire Preferred, Sapphire Reserve, or Ink Business Preferred, you can transfer your points to Southwest at a 1:1 ratio. This is a favorite strategy for travelers because Southwest points have a relatively stable value and no blackout dates. Beyond credit card rewards, several hotel loyalty programs allow transfers to Southwest, including Marriott Bonvoy, World of Hyatt, Choice Privileges, and Best Western Rewards. However, hotel-to-airline transfers generally offer much poorer value; for instance, 3,000 Marriott points might only yield 1,000 Southwest points. It is also important to note that you cannot typically transfer points between different people's accounts unless you are using the Chase "household" sharing rules before the transfer to the airline. While you can "buy" points for someone else, the direct transfer of existing credit card points is the most efficient method to top off a balance for a "Wanna Get Away" fare or a last-minute flight to a destination like Cancun or Hawaii.
