Yes, Southwest Rapid Rewards points can be used for any international flight that Southwest Airlines operates. As of 2026, this includes popular destinations in Mexico, Central America, and the Caribbean (such as Cancun, Cabo San Lucas, Montego Bay, and Punta Cana). Because Southwest uses a "revenue-based" redemption system, there are no blackout dates; if a seat is available for purchase with cash, it is available for purchase with points. The number of points required simply fluctuates based on the current cash price of the ticket. One important thing to note is that while the "fare" can be paid entirely with points, you are still responsible for paying the international government taxes and fees in cash. These can be substantial (often $100 or more round-trip) compared to the standard $5.60 fee for domestic U.S. flights. You can book these flights directly through the Southwest website or mobile app by toggling the "Points" button during your search.
