How to check your Southwest gift card balance online

Southwest Airlines lets you check your gift card balance through their website without needing to call or visit an airport. Go to southwest.com, scroll to the bottom of the page, and look for the link labeled "Check Gift Card Balance" (usually under the Help or Customer Service section). Enter your 16-digit gift card number and the 4-digit PIN on the back of the card, then click to see your current balance.

The balance shown is what you have left to spend on flights, seat upgrades, and other Southwest purchases. The system updates immediately after each transaction, so if you just used the card, wait a few minutes and refresh the page to see the new amount.

If you cannot find the balance checker on the website, call Southwest's customer service line at 1-800-I-FLY-SWA (1-800-435-9792). A representative can tell you the balance over the phone and answer questions about how much value is on the card or whether it has expired.

Key Takeaways

  • You can check your Southwest gift card balance online at southwest.com without creating an account or calling customer service.
  • You will need the 16-digit card number and the 4-digit PIN printed on the back of the physical card to look up your balance.
  • Southwest gift cards do not expire, so an old card with a balance remaining can still be used for flights or purchases.
  • If your card is lost or stolen, contact Southwest immediately so they can flag it and prevent someone else from using the remaining balance.

What you can use your Southwest gift card balance for

A Southwest gift card balance covers the cost of flights on Southwest Airlines. You can use it to book any route Southwest flies, including connecting flights, and the balance applies to the base fare price. If your flight costs more than the card balance, you can pay the difference with another payment method.

Beyond flights, your balance also covers seat upgrades like Early Bird Check-In (which automatically checks you in 24 hours before departure) and Upgraded Boarding (which moves you forward in the boarding order). You can also use the balance to purchase a Companion Pass, which lets another person fly free when you buy a ticket.

The balance does not cover taxes and fees that are added to the ticket price — those must be paid separately. It also cannot be used for rental cars, hotel bookings, or other services that appear on Southwest's website through partner companies.

What happens if your gift card balance is low or zero

If your card balance is lower than the cost of the flight you want to book, Southwest will let you use the remaining balance and pay the difference with a credit card, debit card, or another payment method. You do not have to use the entire balance at once.

If your balance is zero, the card cannot be used for any purchase. You can still keep the card, and if someone adds value to it later (through a gift or refund), that money will be available to use. Southwest does not charge a fee for holding a card with a zero balance.

If you received a Southwest gift card as a refund for a cancelled flight, the balance may take 7 to 10 business days to appear in the system. Check back after that window if the balance does not show up immediately.

Lost, stolen, or damaged gift cards

If your Southwest gift card is lost or stolen, call customer service at 1-800-I-FLY-SWA as soon as possible. Have your card number ready if you can find it. Southwest can place a hold on the card to prevent someone else from using the balance, though they cannot recover funds that were already spent.

If your card is physically damaged — cracked, faded, or unreadable — you can request a replacement. Southwest will transfer the remaining balance to a new card. Bring the damaged card to any Southwest ticket counter at an airport, or call customer service to arrange a replacement by mail.

Keep your gift card in a safe place and do not share the card number or PIN with anyone you do not trust. Treat it like cash — once the balance is used, it cannot be reversed.

Gift card expiration and balance transfers

Southwest gift cards do not expire. If you have had a card for years and never used it, the balance is still valid. You can use it whenever you are ready to book a flight, with no time limit.

You cannot transfer a gift card balance to another person's card or account. The balance stays with that specific card number. If you want to give the card to someone else, you can hand them the physical card and they can use it to book flights under their own name.

If you received a Southwest gift card and want to check whether it has been used before, the balance checker will show you the current amount. There is no way to see the transaction history or original value of the card through the website — only the balance remaining right now.

Refunds and credits to your gift card

When you cancel a Southwest flight that you paid for with a gift card, Southwest refunds the cost back to that same gift card. The refund appears as a credit to the card balance within 7 to 10 business days. You can then use that balance to book a new flight or purchase other services.

If you paid for a flight with a mix of payment methods — part gift card and part credit card — Southwest refunds each payment to the method you used. The gift card portion goes back to the card, and the credit card portion goes back to that card.

Refunds for taxes and fees follow the same rule. If you cancel a flight and the taxes were paid with the gift card, those taxes are refunded to the card balance as well.

Frequently Asked Questions

Can I check my Southwest gift card balance without the PIN?

No. Southwest requires both the 16-digit card number and the 4-digit PIN to look up a balance online. If you have lost the PIN, call customer service at 1-800-I-FLY-SWA and they can help you verify ownership of the card and provide the balance over the phone.

What if the balance checker says my card number is invalid?

Make sure you are entering the number correctly — it should be 16 digits printed on the front of the card. If you are still getting an error, the card may be damaged or the number may have been entered wrong. Call customer service to verify the card number and check the balance.

Can I use my Southwest gift card balance to buy a ticket for someone else?

Yes. You can use your gift card balance to book a flight for any passenger. The person flying does not need to be the gift card holder. Just enter their name and information when you book the flight.

Does my Southwest gift card balance show up in my frequent flyer account?

No. Gift card balances are separate from your frequent flyer account. The balance is tied to the physical card only. If you want to earn points on a flight you book with a gift card, you can link your frequent flyer number to the reservation after you purchase the ticket.

What if I bought a Southwest gift card and it never arrived?

Contact the retailer or website where you bought the card. If you bought it directly from Southwest, call customer service. They can look up the order and either resend the card or issue a replacement. Have your receipt or order number ready.
