Southwest Airlines name change fees by not charging change fees for altering flight plans. Unlike many other airlines, Southwest allows customers to change or cancel their reservations without incurring additional costs. This policy provides significant flexibility and peace of mind, ensuring that travelers can adjust their plans as needed without worrying about extra charges. Additionally, if a customer finds a lower fare after booking, they can rebook at the cheaper rate without paying a penalty, making Southwest a customer-friendly choice for flexible travel.
