Southwest Airlines offers a flexible cancellation policy, allowing passengers to cancel flights without incurring change fees. If you cancel a flight at least 10 minutes before departure, you can receive a full refund in the form of travel credit for future use. Refundable tickets can be refunded to the original payment method, while non-refundable tickets offer credit for future travel. Southwest’s "Wanna Get Away" fares are also refundable as travel credits, making it easy to modify plans. Additionally, travelers can reschedule flights without paying change fees, ensuring peace of mind when plans change unexpectedly. Always check the specific terms before booking.
