On a single Southwest Airlines reservation in 2026, you can use a maximum of two Southwest LUV Vouchers per passenger. If you have multiple vouchers, you may need to book separate one-way flights or combine them using a "rebooking" strategy to utilize their full value. A critical rule to remember is that LUV Vouchers cannot be used to pay for taxes and fees (such as the $5.60 September 11th Security Fee); these must be paid with a credit card or flight credit. If you have three or more forms of payment, Southwest's system will only allow you to apply two vouchers and then require a credit card for the remaining balance. For 2026 travelers, Southwest has made the process easier by allowing vouchers to be converted into "Flight Credits" (which never expire) if you book and then cancel a flight, helping you consolidate smaller amounts into a single usable fund.
