How Southwest fares actually work
Southwest is the rare airline that includes checked bags in the fare, which makes a headline comparison against a cheaper carrier misleading. Its fares are also refundable to travel credit on most tiers, and that flexibility is worth more than a code.
Checked bags are included — comparisons against other carriers need adjusting. The promotional code field is on the booking page before payment. Codes discount the base fare only, not taxes or government charges.
- 1
Adjust comparisons for included bags
Checked bags are included in the fare, so a cheaper competitor fare frequently costs more once bag charges are added.
- 2
Check the fare tier flexibility
Most tiers allow changes with the difference refunded to travel credit, which is worth more than a small discount.
- 3
Understand what a code discounts
Only the base fare is reduced; taxes and government charges are unaffected.
- 4
Check whether the route is served nonstop
Connection patterns differ from other carriers, and a connecting itinerary costs time rather than money.

Southwest Airlines Coupon FAQs
Common questions about saving with Southwest Airlines promo codes
Occasionally — for fare sales and partner offers entered at booking; most savings come from sale fares, points promos and the Companion Pass. Verified codes appear here.
Southwest's famous perk: earn enough qualifying points in a year and a chosen companion flies with you for only taxes and fees on every flight while it's active.
Southwest doesn't charge change fees on fare changes — if your fare drops, rebook and keep the difference as credit (fare rules apply).
Points earned per dollar by fare type, redeemable against fares at a fairly stable value — sales in points mirror cash sales.
The system-wide sales (typically a couple times a year), holiday booking windows and route-launch promos.
Set alerts and book within the sale window — Low Fare Calendar shows each route's cheapest days at a glance.
As of September 19, 2026, there are 7 Southwest Airlines offers available — 5 promo codes and 2 deals, with discounts up to 30% off. They are all listed above, codes first.
Checked bag allowances are included in the fare, which is unusual. A cheaper fare on another carrier frequently costs more once its bag charges are added back.
Most fare tiers allow changes with the difference returned as travel credit, and that flexibility is typically worth more than any promotional discount.
