As of 2026, Southwest Rapid Rewards points are tied to the "Wanna Get Away" fare prices at a relatively fixed rate of approximately 1.3 to 1.5 cents per point. Therefore, 18,000 Southwest points are worth roughly $234 to $270 in airfare value. Because Southwest does not use a "legacy" award chart with blackout dates, the value of your points is essentially a reflection of the cash price of the ticket. If you find a sale fare for $150, it will cost fewer points; if you book a last-minute flight for $400, it will cost more. One major benefit of Southwest points is that they never expire, and they can be used for any seat on the plane with no hidden "redemption fees." For a savvy traveler in 2026, 18,000 points is typically enough for a round-trip domestic flight between mid-sized cities or a one-way "long-haul" flight across the country, making it a very solid mid-tier balance for a frequent flyer.
