My dm's friend has been on hol in oz visiting her dd whilst there she has been diagnosed with dementia. (Details are all a bit blurry but she was ok before she went) however the dd has had enough and is planning on dumping her on the flight and letting her travel back to the uk unassisted. I don't know if she has been declared fit for travel but surely the dd has a duty to let the airline know? What happens if mums friend has a funny turn? We're all worried but don't know enough to do anything. Any advice???
