A Southwest LUV Voucher is a form of digital credit issued by Southwest Airlines as a gesture of goodwill or as compensation for travel disruptions, such as significant flight delays, baggage issues, or poor customer service experiences. Unlike "Flight Credits" (which result from a cancelled ticket and are tied to a specific passenger's name), a LUV Voucher is transferable, meaning it has a voucher number and security code that can be used by anyone to book a flight. In 2026, LUV Vouchers typically carry a one-year expiration date from the date of issue, and the travel must be completed by that date. A key limitation to remember is that LUV Vouchers can only be applied toward the base airfare; they cannot be used to pay for government-imposed taxes and fees (such as the $5.60 security fee), which must be paid with a credit card or flight credit. They are essentially Southwest's way of saying "please give us another chance," and they remain a highly valued tool for savvy travelers looking to offset the cost of their next "Wanna Get Away" fare.
