How to Cancel a Southwest Airlines Flight

Southwest Airlines is making big changes, like charging for bags, rebranding its fares and adding assigned seating. Its once-simple cancellation and refund policy is changing, too. Here’s the latest about how to cancel a Southwest flight.

How to cancel a Southwest flight

If flight plans change, you can cancel your Southwest flight either online, through the app or by calling customer service at 1-800-I-FLY-SWA (1-800-435-9792).

You can either go to the “Manage Reservations” section of the website or the app. From there, if you are logged into your Rapid Rewards frequent flyer account, you can choose a reservation or type in your name and confirmation number and then select the cancel option.

You can cancel a portion of the trip and keep the rest. If you do that, just keep in mind it might change some of the fees associated with the booking, like bag fees. Southwest began charging $35 to check one bag and $45 for the second bag beginning with travel booked, ticketed or changed on or after May 28, 2025.

While it’s often best to cancel as soon as you know you won’t need the ticket, you can cancel up to 10 minutes before the scheduled departure time. So if your flight is at 5 p.m., you have until 4:50 p.m. to cancel.

If you don’t cancel before that time limit, you will most likely lose the entire value of the ticket as a result of Southwest’s no-show policy. The exceptions are if the ticket was a Business Select (soon to be called Choice Extra) or Anytime (or Choice Preferred) fare.

All types of fares can be canceled without a fee.

How to change or rebook your Southwest flight

If your Southwest flight no longer works for you, you may be able to change it.

Wanna Get Away Plus (or Choice), Anytime (Choice Preferred) or Business Select (Choice Extra) tickets can be changed. Basic fares cannot. If you have a Basic fare ticket and need to change it, you can upgrade it to a different type of fare and then make the change.

There is no fee to make an itinerary change, but you will have to pay the fare difference if the new flight costs more than the original one. The reverse is also true. If the ticket costs less, you might get a flight credit. More about those later.

The process to change a flight is similar to the one for cancellations. Go to the “Manage Reservations” option on the website and either type in your name and confirmation number or select your reservation while logged into your Rapid Rewards account. Then select the “Change” option.

You can make a change up to 10 minutes before the scheduled departure time, and if there is more than one person on a reservation and the change is only for one person, you will need to divide the reservation before trying to make a change.

Types of ‘refunds’ on Southwest Airlines

Aside from now charging for checked bags, the second biggest change Southwest has made is how it handles travel credits for things like cancellations and flight changes.

You can use a travel credit to book a future flight, but now there is more of a catch than there used to be.

In the good ol’ days (like earlier in 2025) any funds in a flight credit with Southwest never expired, meaning you could use them whenever you wanted. But only the passenger named on the canceled ticket could use them.

Everything changed on May 28, 2025, when Southwest introduced two types of credits: flight credits and transferable flight credits.

Flight credit

This type of credit comes from canceling a Basic fare or if you downgrade a fare and cannot be transferred to anyone else. Basic fare flight credits for canceling a flight expire after six months from the date originally booked. If you booked a trip six months in advance and canceled one month out, for example, you'd only have one month to use that flight credit.

On or before May 27, 2025, all credits for canceling or changing a flight were called flight credits. If they were issued before that date, they do not expire. So the date they were issued is very important.

Transferable flight credit

Like the name implies, this type of credit can be transferred once to someone else and comes from Wanna Get Away Plus (Choice), Anytime (Choice Preferred) or Business Select (Choice Extra) fares.

Transferable flight credits began on May 28, 2025, and have a specific expiration date, which depends on the type of fare originally purchased and how you paid for it. Most expire in 12 months, but of course, there are exceptions. For example, if you bought a Business Select (Choice Extra) or Anytime (Choice Preferred) ticket with a Southwest gift card, the transferable flight credit will not expire.

The clock for the expiration date begins on the date the fare was purchased and ticketed, not the date you cancel it. So if you buy a Basic fare ticket several months before a trip and then cancel it, you won’t have much time to use those funds.

Your pre-May 28, 2025, flight credit without an expiration date could end up with an expiration date if you apply that flight credit to a new ticket and then cancel that reservation. It will turn into a transferable flight credit and have an expiration date. Make sure you use any credits with an expiration date before those without one.

You can look at all your available flight credits by logging into your Rapid Rewards account, selecting “My Account” on desktop or “My Travel Funds” on mobile or the app and then selecting “Payment.”

When you book a new ticket and want to use a flight credit to pay for it, just add the original confirmation number associated with the flight credit during the payment process. You can use up to three methods of payment for each ticket, and a flight credit counts as one.

If you want to get your money back to your credit card, you’ll need to buy a Business Select (Choice Extra) or Anytime (Choice Preferred) ticket. If you cancel those, you can choose between either a method-of-payment refund or a transferable flight credit.

There is a caveat to that. If you use a flight credit to pay for a Business Select (Choice Extra) or Anytime (Choice Preferred) ticket, any refund will be in the form of a transferable flight credit.

If you used Rapid Rewards points to pay for your refundable ticket, you will get those points back if you cancel.

If you don’t want to mess with Southwest’s policies, another option is to file a travel insurance claim if you have a policy. Or, if you paid for your Southwest flight with a credit card that has travel insurance, you can file a claim with that card.

These two options work only if your policy covers the reason why you decided not to travel.
