Southwest’s change flight policy states that as long as you make your reservation at least a week before departure, you can modify or even cancel it on the same day. If a person marries someone or needs to change their last name, the airline only permits this. It is preferable to use the 24-hour free cancellation option and rebook if you have problems with the initial name. Southwest imposes a penalty if you change your reservation after 24 hours, depending on the type of ticket you have. Additionally, you can request a trip change without additional fees if the airline delays your flight for three or more hours. Flyers who used their reward points to buy the ticket will have their penalty taken out of their own points. Southwest allows users to make changes to a flight ticket up until 40 minutes before takeoff. However, the airline would impose a fine on the same.
