What Is the Southwest Airlines Same Day Flight Change Policy?

The Southwest Airlines same day flight change policy allows you to swap your flight on the day of travel for an alternate flight departing on the same calendar day between the same origin and destination airports. This is a confirmed change, meaning you will have a guaranteed seat on your new flight.

Here is how it works: on your day of travel, you can switch free of airline charges to another flight with space available departing on the same calendar day between the same origin airport and destination airport as your original flight. You must change your flight at least 10 minutes before your original scheduled departure time, or the no-show policy will apply.

The Southwest Airlines same day flight change policy is available for most fare types, but there are important exceptions. Free same-day change is available for Choice Extra (formerly Business Select), Choice Preferred (formerly Anytime), Choice (formerly Wanna Get Away Plus) fares, and Getaways by Southwest vacation bookings. Customers who purchase a Basic fare must first upgrade their reservation to a Choice, Choice Preferred, or Choice Extra fare in order to make a same-day change.

For flights departing on or after January 27, 2026, you will be able to select your seat on your new flight based on your fare, Rapid Rewards tier status, or Rapid Rewards Cardmember status. This is a significant enhancement that gives you more control over your travel experience.

Southwest Airlines Same Day Flight Change Cost – Is It Free?

One of the most common questions travelers ask is about the Southwest Airlines same day flight change cost. The answer is refreshingly simple: it is free of airline charges for eligible fares.

If you have a Choice, Choice Preferred, or Choice Extra fare, you can make a same-day change without paying any change fee. You are no longer required to pay any fare difference either. However, government taxes and fees may apply, but these will be refunded.

This makes Southwest one of the most flexible airlines when it comes to same-day changes. Unlike many other carriers that charge hefty fees for last-minute changes, Southwest's policy is designed to give you peace of mind and flexibility.

What about the Southwest same day change fee for Basic fares? If you purchased a Basic fare, you are not eligible for same-day change. You would need to upgrade your reservation to a qualifying fare first, which would involve paying the fare difference.

What about A-List and A-List Preferred Members? A-List Preferred and A-List Members are not eligible for free same-day change unless they purchase a qualifying fare. However, they can take advantage of same-day standby even with Basic fares.

Southwest Same Day Change 24 Hours – How It Differs from the 24-Hour Cancellation Rule

It is important to distinguish between the Southwest same day change 24 hours policy and the airline's 24-hour cancellation rule.

The 24-Hour Cancellation Rule: Southwest, like all U.S. airlines, allows you to cancel or change your flight for free within 24 hours of booking, as long as you booked at least seven days before departure. This applies to all fares, including Basic.

Same-Day Change: This is a separate policy that applies on the day of travel. You can change your flight to another flight on the same calendar day between the same origin and destination airports. This is only available for Choice, Choice Preferred, and Choice Extra fares, not for Basic fares.

Key Difference: The 24-hour rule is about changing your mind shortly after booking. The same-day change policy is about adjusting your travel plans on the actual day of departure.

Southwest Same Day Standby – What It Is and How It Works

In addition to the confirmed same-day change, Southwest also offers Southwest same day standby. This is a separate option that allows you to retain your current flight while listing for standby on an earlier flight, should a seat become available.

How Same-Day Standby Works:

  • You can list yourself for standby on an earlier flight on the same day of travel between the same origin and destination airports.

  • You can request to be added to the standby list via the Southwest app or mobile web at least 30 minutes before your original flight's scheduled departure.

  • You can also request in person at the ticket counter or departure gate at least 10 minutes before your original flight's scheduled departure.

  • If a seat becomes available, you will be cleared and assigned a seat.

  • You won't lose your original boarding position unless you are officially moved to the new flight.

Eligibility for Same-Day Standby:

  • Same-day standby is available for Choice, Choice Preferred, and Choice Extra fares.

  • A-List and A-List Preferred Members can take advantage of same-day standby even with Basic fares.

  • Basic fare customers who are not A-List or A-List Preferred are not eligible.

Important: Same-day standby is only available for earlier flights on the same day. You cannot list for a later flight through standby. If you want to move to a later flight, you would need to use the confirmed same-day change option.

Southwest Airlines Same Day Flight Change Baggage – What Happens to Your Bags?

If you have checked baggage, the Southwest Airlines same day flight change baggage situation requires some attention. When you change your flight or are cleared from standby, your checked bags may not travel with you.

For Same-Day Change: If you make a confirmed same-day change, your checked bags will generally be transferred to your new flight. However, it is always a good idea to confirm with the agent when you make the change.

For Same-Day Standby: If you are cleared from standby and moved to an earlier flight, you may be separated from your checked bag. Your baggage may arrive on your original flight rather than your standby flight. Southwest is not responsible for delivery charges if your bag arrives on the original flight it was checked on.

What You Should Do:

  • If you are on standby and have checked a bag, let the gate agent know. They may be able to retrieve your bag and move it to your new flight.

  • If your bag does not make it onto your new flight, it will typically be held at the baggage claim office at your destination airport.

  • For international itineraries, baggage transfer may be more complex. You may need to speak with a Customer Service Agent.

Southwest Change Flight for Free – Is It Really Free?

Yes, for eligible fares, the Southwest change flight for free is a reality. If you have a Choice, Choice Preferred, or Choice Extra fare, you can make a same-day change or list for standby without paying any airline charges.

What "Free" Means:

  • No change fee

  • No fare difference (for both same-day change and standby)

  • Government taxes and fees may apply but will be refunded

What "Free" Does NOT Mean:

  • If you upgrade from Basic to a qualifying fare, you will pay the fare difference

  • If you change your flight to a different date (not same-day), fare differences may apply

  • If you are on a Basic fare, same-day change is not available at all

The Bottom Line: For the vast majority of travelers who purchase Choice, Choice Preferred, or Choice Extra fares, same-day changes are genuinely free. This is one of the key reasons why Southwest is so popular among frequent travelers.
