We are arriving on an international flight and will have to clear customs and then move all our bags to Domestic Terminal South.  Since we are moving back to the US from abroad we have over 25 pieces of luggage and our party has an infant and an older member with difficulty walking.  I would like to book a service to transport our bags from just outside customs  (unless you can access international baggage claim) to the Delta check in counter for our flight in the domestic terminal south. Is this service available?
