If you are travelling on Southwest Airlines, it is important to know the airline's policies on changing flights. Southwest is known for its customer-friendly policies, including the ability to change flights without fees or penalties. However, there are some rules and restrictions you need to be aware of when changing your Southwest flight.

First, it's important to understand the different types of fares offered by Southwest Airlines. Southwest offers three types of fares: Wanna Get Away, Anytime, and Business Select. Each fare type has its own rules and restrictions regarding flight changes.

Wanna Get Away fares are Southwest's lowest-priced fares, and they come with some restrictions. If you need to change your Wanna Get Away flight, you can do so up to 10 minutes before your scheduled departure time, but you will need to pay the difference in fare if the new flight is more expensive. If the new flight is less expensive, you will receive a travel credit for the difference, which you can use toward a future Southwest flight within one year of the original booking date. Keep in mind that travel credits are non-transferable and non-refundable.

Anytime fares are Southwest's mid-tier fares, and they come with more flexibility than Wanna Get Away fares. If you need to Southwest change flight, you can do so without paying any change fees, and you will not be required to pay the difference in fare if the new flight is more expensive. If the new flight is less expensive, you will receive a travel credit for the difference, which you can use toward a future Southwest flight within one year of the original booking date. Unlike Wanna Get Away fares, Anytime fares are fully refundable, so if you cancel your flight, you will receive a refund to the original form of payment.

Business Select fares are Southwest's highest-priced fares, and they come with the most flexibility. If you need to change your Business Select flight, you can do so without paying any change fees, and you will not be required to pay the difference in fare if the new flight is more expensive. If the new flight is less expensive, you will receive a travel credit for the difference, which you can use toward a future Southwest flight within one year of the original booking date. Business Select fares are also fully refundable, so if you cancel your flight, you will receive a refund to the original form of payment.

Now that you understand the different fare types, let's look at how to change your Southwest flight. The easiest way to change your Southwest flight is to do so online. You can modify your flight online by doing the following:

1. Go to the Southwest Airlines website and click on the "Flight" tab.

2. Enter your confirmation number and name in the appropriate fields and click "Search."

3. Choose the desired flight, then select "Change Flight."

4. Follow the prompts to select your new flight and pay any fare difference, if applicable.

If you prefer to change your flight over the phone, you can do so by calling Southwest Airlines customer service. Be prepared to provide your confirmation number and name to the customer service representative.

If you have booked your Southwest flight through a travel agent or third-party booking site, you will need to contact the agent or site directly to make changes to your flight.

There are some restrictions to keep in mind when changing your Southwest flight. First, you can only change your flight to a flight that has available seats. If the flight you want to change to is sold out, you will need to select a different flight. Second, if you are changing your flight within 24 hours of your scheduled departure time, you will need to contact Southwest Airlines customer service to make the change, as the online system will not allow changes within 24 hours of departure.
