Promotion code savings are applied before government taxes and fees. Enter promotion code ONBOARD in the Promo Code box when booking during the Booking Period. Seats, days, and markets are limited. If you have entered the promotion code ONBOARD in the Promo Code box on Southwest.com or swabiz.com during the Booking Period, then while selecting your flights, savings in the base fare will be visible as a strike-through of the original fare on eligible flights. 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. Please note that the Department of Transportation (DOT) requires advertised fares to include all government taxes and fees; however, this promotion applies to the base fare only.
Discount is valid on new reservations only. Discount will apply only for select flights booked within the Booking Period, while supplies last, for travel flown within the Travel Period. Changes made to the itinerary after purchase will eliminate qualification 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 a 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 a previously booked flight, or a change to a previously booked flight. Discount is only valid on Southwest.com, swabiz.com, and Southwest Partner Services. The discount is not valid on group travel or Getaways by Southwest™ vacation packages, through Global Distribution Systems, or special fares, such as military and government fares.
