There is people called PSA (Passanger Service Assistance) with every airlines. Some provide free and some for fee. They help passanger to go from one terminal to another or one gate to other. Yoy have to request then in advance. If passanger cannot walk a long distance they provide wheelchair also. Another way is type the following in paper and show the airlines staff or airport staff to help. " I do not speak english. please show me to go to next gate no_______for_______airlines. I am going to ________city in USA. thank you for your help." I hope it will help.
