Additional information:
I have 3 vouchers valuing $200 apiece (all expiring on April 15, 2023).
For use of the vouchers for one individual: Since Southwest only accepts up to 2 vouchers per transaction (not 3), in order to take full advantage of all 3 vouchers, purchase 2 one way tickets (use 2 vouchers for 1 one way ticket and 1 voucher for the return flight transaction).
Southwest is happy to help you through this process - applying the vouchers when purchasing your flights.
Use vouchers during payment step on the Southwest site (enter the voucher number in the gift card/voucher option).
