Just looking for advice please. We are currently planning a trip to Australia in mid 2018 for a family wedding. Our only concern currently is DSD's travel arrangements. DSD has high functioning ASD, is classed as a vulnerable adult and gets lost/very confused easily. Our plan A was that DSD would fly out with myself and dh. However we (myself and dh) are now (unavoidably) going to be flying out before DSD can get time off work. Hence she will need to travel alone and most likely the same coming back. She has never flown longhaul before either which doesn't help. A relative will meet her on arrival in Australia but we're worried that she will struggle with catching her connecting flight in a large airport/multiple terminals (most likely going via Singapore or Dubai currently).
We've been looking at the option of a chaperone service, similar to those for unaccompanied children but can't find any airline offering such a service for adults (just children). Has anyone got any advice/experience/suggestions of airlines that might offer such a service? TIA :)
