also, the flights rarely seem to leave SXM on time so you will probably have less than an hour. it is usually a long wait for luggage in Charlotte so you can clear customs and then you have to go back through security to board your connecting flight. (On a side note, I wish they would find some way to keep those of us with connections inside security.) Maybe you could make it if you only had carry-ons but I don't think it is possible with luggage, even on a good day in Charlotte. You might want to call AA and see if there are any options for you.
