Discount availability may vary by destination, flight, and day of the week, and won’t be available on some flights that operate during very busy travel times and holiday periods.

Changes made to the itinerary after purchase will eliminate qualifications for this promotion and will result in forfeiture of any promotion code savings. The discount is only valid with the provided promotion code and is not combinable with other promotion codes or fares. All reward travel is subject to taxes, fees, and other government or airport-imposed charges of at least $5.60 per one-way trip. Applicable taxes, fees, and other government or airport-imposed charges can vary significantly based on your arrival and departure destination. The payment of any taxes, fees, and other government or airport-imposed charges is the responsibility of the Passenger and must be paid at the time reward travel is booked with a credit card, flight credit, or Southwest® gift card. Fares are subject to change until ticketed. Offer applies only to published, scheduled service. Additional fees and charges for optional products and services may apply.

Offer is not redeemable for cash and may not be used in conjunction with other special offers, or toward the purchase of a gift card, or previously booked flight, or change to a previously booked flight.
