Southwest's 24-Hour Window and How It Works

Southwest Airlines allows you to cancel any flight within 24 hours of booking without a cancellation fee. This applies to all ticket types — Basic Economy, Anytime, and Business Select. The 24-hour period starts the moment your booking is confirmed, not when you purchase the ticket.

If you booked through Southwest's website, a travel agent, or a third-party booking site, the same rule applies. You can cancel by logging into your Southwest account, calling 1-800-I-FLY-SWA, or visiting an airport ticket counter. The refund or credit goes back to your original payment method within 7 to 10 business days if you paid by credit card, or as a travel credit if you paid cash.

After the 24-hour window closes, you cannot cancel for free. You can still change your flight to a different date at no charge — that is Southwest's main benefit over other airlines — but you cannot get money back.

Key Takeaways

  • You have 24 hours from the moment you book to cancel without paying a fee, regardless of how far away your flight is.
  • Cancellations made within 24 hours return as a credit to your original payment method or as a travel credit, depending on how you paid.
  • After 24 hours, you lose the right to cancel for free, but you can still change your flight date without a change fee.
  • The 24-hour clock starts when your booking is confirmed, not when you receive your confirmation email.
  • You can cancel through Southwest's website, by phone, or at an airport ticket counter.

How to Cancel Within the 24-Hour Window

The fastest way to cancel is through Southwest's website. Log in to your account, find your reservation under "Manage Reservations," and select the flight you want to cancel. Click "Cancel Flight" and confirm. You will see the refund or credit amount on screen when ready, and the transaction processes within minutes.

If you booked through a third-party site like Kayak, Expedia, or Google Flights, you can still cancel directly through Southwest's website if you have your confirmation number. You do not need to go back to the site where you booked. If you cannot find your reservation, call 1-800-I-FLY-SWA and have your confirmation number ready.

Calling Southwest takes longer during peak hours (early morning, evening, and weekends), but the process is straightforward. A representative will pull up your reservation, confirm the cancellation, and tell you whether the refund goes to your card or as a travel credit.

What Happens After 24 Hours

Once the 24-hour window closes, Southwest will not refund your money. You can still change your flight to any other Southwest flight at no charge — you only pay the difference if you book a more expensive flight. This is different from most other airlines, which charge $75 to $200 to change a flight.

If you do not use your ticket at all, it becomes a travel credit that never expires. You can use it for any Southwest flight in the future, for any passenger. The credit is tied to the confirmation number, not to your name, so you can give it to someone else if you want.

If you need to cancel after 24 hours and do not want to change your flight, you have no way to get a refund. Southwest does not offer refunds for schedule changes, weather delays, or cancellations made by the passenger after the 24-hour window. Your only option is the travel credit.

The Difference Between Cancellation and Changes

A cancellation means you want your money back or a credit. A change means you want to fly on a different date or to a different destination. Southwest charges no fee for changes at any time, but you must pay the fare difference if the new flight costs more.

If you cancel within 24 hours, you get a full refund or credit. If you change your flight after 24 hours, you keep the value of your original ticket and pay only the difference. For example, if you booked a $150 flight and want to change to a $200 flight after 24 hours, you pay $50 more. If you want to change to a $120 flight, you get a $30 credit toward future travel.

Many people use the change option instead of canceling because it preserves the full value of their ticket. You can change your flight as many times as you want, as long as you do it before your original flight departs.

Refunds Versus Travel Credits

How you paid determines what you get back. If you paid by credit card, debit card, or PayPal, Southwest refunds the money to that account. If you paid by cash or check at an airport ticket counter, Southwest issues a travel credit instead — you cannot get cash back.

Travel credits never expire and can be used for any Southwest flight. They are not tied to a specific passenger, so you can give your credit to a family member or friend. The credit is attached to your confirmation number, and whoever uses it needs that number to book.

Refunds to credit cards take 7 to 10 business days to appear. The time depends on your bank, not Southwest. Some banks post refunds faster; others take the full 10 days. If you do not see the refund after 10 business days, contact Southwest with your confirmation number and the date you canceled.

Special Cases: What the 24-Hour Rule Does Not Cover

The 24-hour cancellation window applies only to cancellations you request. If Southwest cancels your flight due to weather, mechanical issues, or crew problems, you have different rights. Southwest will rebook you on the next available flight at no charge, or you can request a refund. You do not have to decide within 24 hours.

If your flight is delayed significantly — usually three hours or more — you can still change to a different flight at no charge, but you cannot cancel for a refund unless Southwest officially cancels the flight. A delay is not the same as a cancellation in Southwest's system.

If you purchased a non-refundable Basic Economy ticket outside the 24-hour window, you still cannot get a cash refund, but you can change to another flight for free. The travel credit option does not explore to Basic Economy — you either use the ticket or lose it.

Frequently Asked Questions

Does the 24-hour cancellation window explore to Basic Economy fares?

Yes. Southwest's 24-hour cancellation policy applies to all fare types, including Basic Economy. After 24 hours, you cannot cancel for a refund, but you can change your flight to another date at no charge.

What if I booked my Southwest flight more than 24 hours ago and want to cancel now?

You cannot get a refund, but your ticket becomes a travel credit that never expires. You can use it to book any Southwest flight in the future, or give the credit to someone else using your confirmation number.

If I cancel within 24 hours, how long does the refund take?

Refunds to credit cards take 7 to 10 business days. The time depends on your bank's processing speed. If you paid by cash, you receive a travel credit instead of a refund.

Can I cancel my flight and get a refund if Southwest delays it by several hours?

A delay does not give you the right to cancel for a refund. You can change to a different flight at no charge, but if you want money back, Southwest must officially cancel the flight. Contact Southwest directly to ask about your options.

Is the 24-hour cancellation policy the same if I booked through a travel website?

Yes. The 24-hour window applies no matter where you booked — Southwest's website, a travel agent, or a third-party site. You can cancel directly through Southwest's website using your confirmation number.
