No, Southwest Airlines Rapid Rewards points do not expire. This policy was officially implemented in late 2019 and remains a core benefit of the program in 2026. Prior to this change, points would expire if there was no "earning activity" on the account for 24 months, but that rule has been permanently abolished. This means that as long as your account remains open, your points will stay there indefinitely until you decide to use them, regardless of how often you fly or use a Southwest co-branded credit card. This "no-expiration" policy is a major competitive advantage for Southwest, as it allows casual travelers to slowly accumulate points over several years for a "dream trip" without the fear of losing their progress. It is important to note, however, that while the points don't expire, the account itself could theoretically be closed if the airline terminates the program or if there is fraudulent activity, but for the vast majority of users, your points are safe and ready to be redeemed for any seat, on any flight, with no blackout dates.
