Ok heres my two cents. Yes DFW is the Biggest hub in the system, but that does not give it some magical free pass from the "right sizing" of hubs in the proposed AA system. Like ALL of the hubs in the system there are surely some places that US's hubs could serve better than DFW can east west, whether you want to face it or not. While CLT may lose some flights. they don't fly to that many western destinations to start with. So I think it will all equal out minus maybe some Latin, and CLT will keep its INTL resume which is already relatively small as is. Don't think that DFW does not see at least some Reduction. Just being DFW does not give it an automatic free pass from right sizing.
