Southwest Airlines offers flexible flight changes with no change fees. Passengers can modify their flights up to 10 minutes before departure; however, fare differences may apply. Same-day changes and standby options are available, with eligibility varying by fare type. For instance, Business Select and Anytime fares include free same-day changes, while Wanna Get Away fares may incur additional costs. It’s important to note that Basic Economy fares, introduced in May 2025, are non-changeable and non-refundable. Always review fare rules when booking with AeroFlyTicket. https://www.aeroflyticket.com/southwest-airlines-flight-change-policy/
