Southwest Cancellation Policy has an accommodating cancellation policy. Flights can be cancelled up to 10 minutes before departure without incurring any costs. The full ticket price is reimbursed as a travel credit that can be used to make future reservations. There are no cancellation or change penalties, and the travel funds are valid for one year from the date of purchase. If you cancel a non-refundable “Wanna Get Away” fare, the monies are converted into reusable travel credits. Overall, Southwest’s approach is customer-friendly, allowing travellers to change their travel plans with minimum cost consequences.
