Every person who is making a reservation on a flight must be aware of the no show policy at Southwest. As mentioned in the Southwest Airlines Cancellation Policy of the, unless you cancel your flight reservation 10 minutes prior to the supposed flight and do not report to the flight at all, you will lose the entire amount of a non-refundable ticket such as Wanna Get Away. Anytime or Business Select refundable fares are still able to be used or refunded. Try as much as possible to cancel early before your trip has ended so as not to have lost the price of your booking even in case of unexpected changes in plans. This is a small move which can save you money and also travel with ease.
