In 2026, if you cancel a Southwest flight that was paid for (wholly or partially) with a LUV Voucher, the value of that voucher is typically reissued as a Flight Credit. Unlike the original LUV Voucher—which often cannot cover taxes and fees—the resulting Flight Credit is more flexible and can be applied toward the total cost of a future ticket. However, the original expiration date of the LUV Voucher usually carries over to the new credit. It is important to know that while Southwest "Wanna Get Away" fares are non-refundable to your credit card, they are fully "re-useable." If your voucher was set to expire in June and you cancel the flight in May, your new credit will still likely expire in June. For 2026 travelers, it’s a "pro-tip" to check your "Travel Funds" portal on the Southwest app to track the specific expiration of any reissued credits following a cancellation.
