Since this is China Air, I am not sure calling them would help, though it couldn't hurt. Since they are in *A, you could try UA next and see if they can help you or point you in the right direction.

You could also just come to checkin counter with printed itinerary and see if they could issue a pass through security.

Otherwise wait between term D and E where they will exit customs (having already cleared immigration).

One other though, IAH, like many other airports have volunteer ambassadors, and if you could find their phone number, they may be able to help you.
