My mom would be travelling in plane for the first time. She would fly with China southern from Delhi to Melbourne. She is not well versed with English and has problem in knees. She is travelling alone. We booked wheelchair service for her. My flights has to be cancelled so now she will travel alone. I am scared and she too. Can someone please provide feedback on wheelchari service especially when the passenger is alone and does not speak English? It would really help. And is there any forum where I can ask if anyone is travelling in the flight on the same date so that I can request them to assist my mom if needed.
