The Southwest Airlines Flight Change Policy is designed for travelers who need flexibility. The airline allows flight changes without any charges a standard modification fee. This means you can update your travel date time or route without paying a penalty. If the new ticket price is higher you only pay the extra amount. When the new fare is lower Southwest provides the remaining value as future travel credit. Changes must be completed before the flights scheduled departure. Passengers can manage changes online through the mobile app by phone or at the airport. Because of this flexible approach the Southwest Airlines Flight Change Policy is considered one of the most traveler-friendly options in the US airline market. Contact Us: +1 (833) 284-2027
