Hi, my relatives have an international flight from Moscow to Las Vegas that connects in JFK terminal 3 (both Delta). As far as I know, they have to pick up their luggage to go through customs. How do they check in their bags on the domestic flight to Las Vegas? Do they have to go to the main Delta check in desk? Is it outside of the secured area? What signage should they look for (they do not speak much English). Thank you! I appreciate your help!
