Parents are travelling from UK to ORD and transferring to a ROC bound flight from ORD. My mother has a back condition that requires assistance. I would like services that can greet them at the gate and help them get through passport control, baggage collection, and customs as expediently as possible without a great deal of walking or lifting. They then have to make a flight connection within 2 hours from landing at ORD too. So I am concerned about them getting across ORD in time to catch their flight.
