It's simple to change a Southwest flight, and there are no additional fees. If you want to go on a different date, change your departure or arrival time, or even fly to a new location entirely, changing your flight can be helpful. Instead of cancelling and rebooking, altering a flight offers the advantage that, if you booked EarlyBird Check-in, the fee will remain with your reservation. If you purchase this add-on and then need to cancel your flight, you won't get your money back. While rescheduling a Southwest ticket is free, you will be responsible for paying the difference in price if your new itinerary is more expensive. On the other hand, if the cost of your flight decreases, you'll get the difference back as a credit. The credit you receive when cancelling a flight has a 12-month validity period and cannot be transferred.
