I am writing to request special assistance for my 79-year-old mother who will be travelling from Bogota to Brisbane, with layovers at Mexico City International Airport and Vancouver International Airport. Given her age and the challenges associated with navigating large airports, I kindly ask for comprehensive assistance, including wheelchair services and a personal escort to help her through check-in, security, customs, and immigration processes, as well as during transit between gates. It would be greatly appreciated if someone could also assist her with her boarding and disembarking from the aircraft.
