I dont know if they are there, but when I've been to the major airports in Houston/Austin/Nashville they had people outside the gates that could assist you if you needed (or could be paged to help)...I'm thinking that they are a diff version of Skycaps than the ones that check your luggage because I've noticed they dont work for specific airlines. They usually are wearing black polos (Or at least the 4 airports I've been in lately they have). You could always call the airport and find out if they have something like that.
