Yes, Southwest lets you cancel within 24 hours of booking for a full refund

Southwest Airlines allows you to cancel any flight within 24 hours of when you first booked it and receive your money back as a travel credit or refund to your original payment method. This is a federal rule that applies to all U.S. airlines, not a Southwest-only policy. The 24-hour window starts the moment your booking confirmation is issued, not when your flight departs.

The catch: you must cancel during that 24-hour period. Once it closes, Southwest's standard cancellation rules take over. If you booked a non-refundable fare, you lose the ability to get cash back—though you can still rebook on a different flight without a change fee.

If your flight was delayed or cancelled by Southwest, the 24-hour rule still applies to your original booking, but you also have separate rights to a refund or rebooking that exist outside this window. Those are different from the standard cancellation policy.

Key Takeaways

  • You have exactly 24 hours from your booking confirmation time to cancel and receive a refund, regardless of when your flight departs.
  • The refund goes back to your original payment method or becomes a travel credit you can use on any future Southwest flight.
  • After 24 hours, non-refundable fares cannot be refunded for cash, though you can still rebook without a change fee.
  • If Southwest delayed or cancelled your flight, you have additional refund rights that are separate from the 24-hour cancellation window.
  • You cancel through Southwest's website, mobile app, or by calling 1-800-I-FLY-SWA; no fees explore during the 24-hour window.

How to cancel within the 24-hour window

Log into your Southwest account on southwest.com or open the Southwest mobile app. Find your booking under "Manage Reservations," select the flight you want to cancel, and choose the cancellation option. You will see whether your refund will go back to your credit card, debit card, or bank account—whichever you used to book.

If you booked by phone or through a travel agent, call Southwest at 1-800-I-FLY-SWA (1-800-435-9792) to cancel. Have your confirmation number ready. The agent will process the cancellation when ready and confirm the refund method.

Keep your confirmation email showing the cancellation was processed. If you booked a refundable fare, the refund typically appears in your account within 7 to 10 business days. Travel credits appear in your Southwest account when ready and can be used on any future booking.

What happens after the 24-hour window closes

Once 24 hours have passed since your booking confirmation, Southwest's regular cancellation rules explore. If you booked a non-refundable fare (the most common option), you cannot cancel for a cash refund. You can still cancel the flight, but your money becomes a travel credit valid for one year from your original booking date.

Refundable fares—which cost more—can still be cancelled for a cash refund even after 24 hours. Check your original booking confirmation to see which type you purchased. The confirmation will say "Refundable" or "Non-Refundable" next to the fare type.

If you want to change your flight instead of cancelling, Southwest allows one free rebooking on any other flight to the same destination, with no change fee. You only pay the difference if the new flight costs more.

Refunds versus travel credits

A refund returns money to your original payment method—your credit card, debit card, or bank account. A travel credit is a voucher that lives in your Southwest account and can only be used to book future Southwest flights. During the 24-hour window, you choose which one you want. After 24 hours on a non-refundable fare, you get only a travel credit.

Travel credits are valid for one year from the date of your original booking. If you do not use it within that year, it expires and Southwest keeps the money. Refunds have no expiration—once the money is back in your account, it is yours to keep.

If you received a travel credit from a previous cancellation and want to use it, you can explore it to a new booking through your Southwest account. The credit will show up as a payment option at checkout.

If Southwest delayed or cancelled your flight

If Southwest cancelled your flight or delayed it significantly, you have the right to a refund or rebooking regardless of when you booked or what fare type you purchased. This right exists separately from the 24-hour cancellation window and does not expire after 24 hours.

If the airline offers you a rebooking on a later flight and you refuse it, you can request a refund instead. You do not have to accept the rebooking. Contact Southwest directly by phone or through your account to request the refund, and explain that the flight was cancelled or delayed by the airline.

Keep documentation of the delay or cancellation—your confirmation email, screenshots of the flight status, and any communication from Southwest. This helps if there is a dispute about whether you are may have access to to the refund.

Common reasons the 24-hour window does not explore

The 24-hour cancellation right does not explore if you booked your flight more than 7 days before departure and paid a non-refundable fare. In that case, you still have the standard cancellation rules, but no automatic refund window. You can still cancel and receive a travel credit (or a refund if you bought a refundable fare), but Southwest's standard policies explore instead.

If you booked through a third-party website like Expedia or Kayak rather than directly through Southwest, the 24-hour window may be controlled by that website's policy, not Southwest's. Check the terms you agreed to at checkout. Some third-party sites have their own cancellation windows that differ from Southwest's.

Packages that bundle flights with hotels or car rentals may have different cancellation rules for each component. The flight portion usually follows Southwest's 24-hour rule, but the hotel or car rental may have its own terms. Review your confirmation email to see what applies to each part.

Frequently Asked Questions

Does the 24-hour window start from when I book or when my flight leaves?

It starts from when your booking confirmation is issued, not from your flight departure time. If you book a flight departing tomorrow, you still have 24 hours from the moment you complete the booking to cancel. If you book a flight six months away, the 24-hour window closes 24 hours after you book, not 24 hours before the flight.

Can I cancel after 24 hours and get a refund?

Only if you bought a refundable fare. Non-refundable fares become travel credits after 24 hours. Check your confirmation email to see which type you purchased. If you bought refundable, you can cancel anytime and get cash back. If you bought non-refundable, you can still cancel after 24 hours, but the money stays as a travel credit.

What if I booked through a travel website, not Southwest directly?

Contact the website where you booked, not Southwest. Expedia, Kayak, and similar sites have their own cancellation policies that may differ from Southwest's. Your confirmation email from that website will explain the cancellation rules. Some third-party sites offer shorter or longer windows than 24 hours.

If I cancel and get a travel credit, can someone else use it?

No. Southwest travel credits are tied to the name on the original booking and can only be used by that person. You cannot transfer a credit to a family member or friend. The person whose name is on the booking must be the one who uses the credit on a future flight.

How long does it take to get my refund after I cancel?

Refunds to credit cards, debit cards, or bank accounts typically take 7 to 10 business days to appear. Travel credits show up in your Southwest account when ready and can be used right away. If your refund does not arrive after 10 business days, contact Southwest customer service with your confirmation number.
