Is there a specified time limit for flight changes or cancellations?
Yes! Southwest allows customers to change or cancel their flight up until 10 minutes before the scheduled departure time. Customers can make changes or cancel their Southwest flight up to 10 minutes after the flight departure. If you forget to change or cancel, your travel funds for that flight will be forfeited.
For example, if you've purchased a $79 Wanna Get Away ticket for a one-way and didn't make changes to the flight or canceled it, your $79 will be forfeited in that case. If you have canceled your ticket before the "10 minutes before departure" mark, your $79 will be changed to a reusable travel fund for future use.
