I love Southwest for its ability to check fares and if there is a lower fare on the same flight you are booked on, you can change flight and receive credit. No more. If you attempt to do that, Southweest will not let you make a change. (Same with United). I guess what you have to do is cancel your booked flight and then rebook the same flight with your travel credits. Is this correct? Thanks,

This is incorrect. I did this today for a few different flights as I travel weekly and make frequent changes.
