Hi ZAP, my friend from China will fly to Mexico via AA (PVG-DFW-BJX) on Nov. 17th. She speaks very little English. She has 2 and a half hour to make connection. From your previous comments, I understand that she doesn't need claim the luggage, but she still need to go through immigration and customs, and then go through the security. It seems like she does not need to leave the terminal D since both sections are international via AA, is my understanding correct? Is there any assistance available for mandarin speaker at DFW? Any comments will be highly appreciated.
