Yes, there are two primary ways to buy Southwest flights using Chase resources in 2026. First, if you have a Chase Sapphire Preferred® or Reserve® card, you can transfer your Chase Ultimate Rewards points directly to Southwest’s Rapid Rewards program at a 1:1 ratio. This is often the best value, as it allows you to book any available seat on Southwest’s website using points. Second, you can use your Chase points to book Southwest flights through the Chase Travel℠ portal; however, Southwest flights often do not appear in the automated search results, so you may need to call the Chase Travel center to complete the booking. Additionally, using a co-branded Southwest Rapid Rewards® Credit Card from Chase to purchase flights directly on Southwest.com allows you to earn up to 4x points per dollar spent. These methods make Southwest one of the most accessible airlines for Chase cardholders looking to maximize their travel rewards for domestic and Caribbean trips.
