My Mandarin (and Suzhounese) speaking in-laws will be traveling PVG/ORD/AUS in October. I'm trying to give them as much information as I can about what to expect and how to make the transfer at ORD. The O'Hare maps, both at the O'Hare and AA web site don't have a lot of detail, but it looks like they'll clear customs and immigration in terminal 5, recheck their bags, take a shuttle train to terminal 3 and then go through security and out to the gate. They speak no English. Will there be any customer service people to help them out? Is there anything they need to know? They have three hours between flights, so I'm not that worried about time. I also think there's a good chance of a Chinese speaking fellow passenger on their inbound flight also making a transfer who could help them out, but any advice would be appreciated.
