OP, how long is your DFW layover? Is it possible to check your bags to the final destination and pack a few essentials in your carry-on for your overnight layover?

If you're on an international flight and departing again within 24 hours, there wouldn't be another charge to check your bags.
It looks like you are good to go.

Thanks. The overnight layover is around 15 hours, so I'm not sure they would check it through. And since it's to a Caribbean destination, I wasn't sure whether domestic or international baggage rules would apply. My ticket from AS doesn't say and it's not clearly spelled out on AA's website, thus the question.
