. Are you unchecking your luggage and re-checking it yourself, or are they just transferring the luggage themselves? CLT is a pretty small airport and very organized, so it should be enough time for them to transfer the luggage from plane to plane. But, if you are unchecking and rechecking yourself, I'd be really careful and pack some clothes in your carryon. It really barely takes any time to go through security at CLT, but I'd be worried if I would have to claim my baggage at the baggage claim and re-check (it does get busy with business travelers during the week). I'd maybe even email customer service and get a response in writing just in case.
