For years a Southwest flight credit was the safest money in travel: it never expired. That changed for tickets bought from May 28, 2025. Most credits now have a date, the clock starts earlier than people expect, and travelers on Reddit and FlyerTalk keep finding out the day after a credit vanished from their account.
This guide covers the rules Southwest publishes, then what travelers report actually happens: where credits hide, the checkout traps, and the ways people keep a credit from expiring.
Do Southwest flight credits expire?
It depends on when you bought the ticket and which fare you bought, from Southwest’s fare rules:
| Ticket | Credit when you cancel | Expires |
|---|---|---|
| Bought or changed on or before May 27, 2025 | Flight credit | Never |
| Basic | Flight credit, for the named traveler only | 6 months from purchase |
| Choice | Transferable Flight Credit | 12 months from purchase |
| Choice Preferred, Choice Extra | Refund to your card if you cancel in time; a Transferable Flight Credit if you don’t | 12 months from purchase |
When does my Southwest credit expire?
It’s on your original confirmation email, not the cancellation email.
It’s a fly-by date, and it starts at purchase
Southwest says all travel must be completed by the expiration date (Transferable Flight Credit rules), and the clock runs from the day the original ticket was bought, not the day you cancelled. Members on FlyerTalk describe the usual surprise: cancel a Basic ticket four months after booking it and the credit has about two months left, often not enough for a trip you haven’t planned yet.
How you end up with a Southwest credit
- You cancel. Do it at least 10 minutes before the scheduled departure. Miss that and Southwest says the funds can be forfeited.
- The fare drops and you change to it. On Choice, the difference comes back as a credit with the same 12-month clock. On Choice Preferred and Choice Extra, it goes back to your card.
- You downgrade to a cheaper fare, for example from Choice Extra to Choice. The difference becomes a credit.
- You cancel a seat or other extra you paid for separately. Travelers report it comes back as its own credit, separate from the ticket.
One more case: if you never cancel a Choice Preferred or Choice Extra ticket and just don’t fly, Southwest turns it into a Transferable Flight Credit instead of a refund.
How to check your Southwest travel funds
- Logged in: open your Rapid Rewards account on southwest.com or in the app and go to Travel funds. Credits issued to you while logged in show up there with their expiry dates.
- Not logged in, or the credit isn’t there: use Check travel funds with the confirmation number and the passenger’s first and last name.
When a credit seems to be missing
- It expired. Travelers on r/SouthwestAirlines report that credits drop off the account the day they expire. If you think yours was still valid, you’ll need the original confirmation number to get an agent to find it, so keep those emails.
- The name doesn’t match. Credits issued with a suffix such as Jr. or III, or to someone with two first names, can fail to attach to an account or to a new booking. Travelers with two first names report it works if they put the second one in the middle name field at checkout (r/SouthwestAirlines). Otherwise, call and an agent can apply it.
- It was booked by someone else. A credit lives with the confirmation number it came from. Ask whoever booked for it.
How to use a Southwest flight credit
- Search and pick your flights on southwest.com or in the app.
- On the payment page, apply the credit. Ones in your account are listed; for others, enter the confirmation number and name.
- Pay any difference with a card or gift card.
Checkout rules that trip people up
- Three forms of payment per passenger. Every credit counts as one (Southwest’s rules), so a card plus a gift card leaves room for only one credit.
- Mixing an old credit with new money can shorten the new money’s life. Travelers report that when a ticket is paid partly with an expiring credit and partly by card, cancelling it later gives you a credit for the whole amount with the earliest expiry (r/SouthwestAirlines, April 2026). If there’s a real chance you’ll cancel, don’t mix them.
- Leftover value stays a credit under the same confirmation number, with the same expiry.
- Credits can’t pay for Getaways by Southwest vacation packages, which have their own vacation travel credits.
Southwest Transferable Flight Credit
Choice, Choice Preferred and Choice Extra tickets turn into a Transferable Flight Credit when you cancel or downgrade. The rules, from Southwest’s help center:
- You can transfer it once.
- It goes between Rapid Rewards members, so the person you give it to needs a free account.
- It keeps its original expiry date.
- Partner itineraries don’t create one.
Southwest walks through the steps in its transfer guide. Basic credits can’t be transferred at all, which is one more reason to think twice about Basic when plans might change.
Points bookings: what happens to your Rapid Rewards points
- Cancel in time and the points go back to the Rapid Rewards account that booked the flight (Southwest’s fare rules).
- Watch what happens to the taxes. The few dollars of taxes you paid in cash can come back as a flight credit with its own expiry. One traveler took the $5.60 as a Basic credit and then couldn’t use it on a flight more than six months out (r/SouthwestAirlines, July 2026).
- When the points price drops, change to the same flight at the lower price in Manage reservations and the difference goes back to your account as points, which don’t expire. Basic can’t be changed, so it’s cancel and rebook. The full steps are in our Southwest price drop guide.
Keeping a Southwest credit from expiring
Southwest doesn’t offer a way to extend a credit, and because it’s a fly-by date, booking a flight after the expiry date isn’t an option. Travelers report three things that work, from most to least reliable.
1. Use it on a trip you’d take anyway, before it expires
The only sure option. Even a short trip uses the credit, and anything left over stays a credit with the same date.
2. The gift card reset (traveler reports)
Travelers on r/SouthwestAirlines describe resetting an expiring credit to no expiry (December 2025, step by step, still working in October 2026):
- Book a Choice Preferred fare for one passenger that costs a little more than the credit.
- Pay with the credit, and pay the rest with a Southwest gift card.
- Wait 10 to 30 minutes, then cancel and choose to keep the funds as a credit.
Reported pitfalls: it no longer works with a Choice fare, cancelling within about five minutes or on a booking with several passengers leaves the old expiry in place, and Southwest could close it at any time. Check the new expiry date in your account before you rely on it.
3. Ask after it expires
Travelers report that agents can extend an expired credit once, by about three months, and only after it has expired (r/SouthwestAirlines, March 2026; one traveler was offered 45 days). Southwest doesn’t refund expired credits as cash; some agents offer a LUV Voucher instead (r/SouthwestAirlines, January 2026). Have the original confirmation number ready.
When the fare drops after you book with a credit
Southwest has no change fees on Choice and up, so a lower fare on the same flight is money you can take back: as a new credit on Choice, to your card on Choice Preferred and Choice Extra, and as points on a points booking. Basic can’t be changed, so the only option is to cancel for a credit and book again, and that credit keeps the original 6-month date.
The step-by-step version, with when it’s worth it, is in our Southwest price drop policy guide and the short checklist on Plot’s Southwest page.
Let Plot watch the flight you book with your credit
Forward your Southwest confirmation and Plot Pro watches the fare, in dollars or in Rapid Rewards points. When it drops, you get the new price and the steps for your fare. Plot doesn’t track your credit balances, so keep your confirmation emails and note the expiry dates.
