When compared to other airlines, Southwest Airlines offers one of the most accommodating change and cancellation policies. The rules are simple to understand. The last-minute travel modifications can be extremely inconvenient and even expensive compared to the original ticket cost. However, Southwest Airlines does not impose a change or cancellation fee in Southwest Airlines cancellation policy. Within 24 hours of booking, this airline offers a full refund. If the 24-hour window has passed and the ticket is non-refundable, the money is still due. It is applied to upcoming airline travel during a 12-month period. Southwest provides both a free same-day ticket change policy and a free ticket change policy. Customers are not restricted by the company's ticket change policy from travelling to the same destination as their original reservation. It will continue be free even if you decide to go to a totally different place, which is an occasional policy. If you missed a Southwest flight, you may be eligible for ticket cancellation under the terms of the policy.
