SWA ? re: changing a flight time (same date)

[3PRINCESSMOM]

Can I book an early flight now then change it to a later flight later? Is there a charge involved? How much?

What about if I book a flight for 12/11 now (that is when current schedule ends), but change to a 12/12 flight when it becomes available? Same questions...??? Thanks!

With SWA any changes will only cost you the difference in the fare. It's it's more you pay more if it's less you get a credit.
