Southwest Airlines Coupon Codes

Using Southwest Airlines Promo Codes at Checkout

Most Southwest Airlines discounts are entered in one of two places: the promo code box in the cart, or the discount code field on the payment screen in the Southwest Airlines app. If you are buying on a phone, the app often has more codes available than the website does.

1. Pick a code. Start with one that has a clear expiry date, because those are the ones the retailer is actively rotating.
2. Add your items first. A minimum spend condition can only be checked against a populated cart.
3. Paste the code exactly. Some codes are case-sensitive, and a trailing space will be rejected.
4. Apply it and check the total. The discount should show on the order summary before you pay.

If the code is refused, the offer is usually limited to a specific product range, a minimum spend that was not reached, or an order that has to be placed in the app rather than on the website.

Getting the Best Deal from Southwest Airlines

Coupon codes for Southwest Airlines are not permanent. Retailers change them as a campaign starts, ends or rotates, and a code that worked last week may be refused today. That is normal, and it is why every code on this page carries its expiry date where one was published.

• Short flash codes run for a day or two and are usually tied to a specific campaign.
• New-customer codes work once, on a first order, and often only on the app.
• Loyalty codes need a membership account before they will apply.
• Sitewide codes often exclude sale items, premium ranges, gift cards and other brands.

Southwest Airlines also runs automatic discounts that need no code at all — those are listed above, and they are often worth more on a large order than a percentage code.
