Hello, I’ve posted this already elsewhere, but I flew to Kenya with my OH who has moderate/ severe dementia in October. Flew BA who were excellent, let the airline know & you can have assistance but doesn’t have to be wheel chair! My OH would not get into one! You just get fast tracked through & can pre board flight. Let stewardess know as soon as on board as they may not know. Get him to wear a Sunflower lanyard as most people recognise this as hidden disability. Going to the toilet on long flight was tricky as he can’t shut himself in! So we managed with curtains round the doors but again stewards offered to help stand by the door to stop others going by! Use some meds to relax him if needed. Speak to GP. I have added complication as he’s a smoker but patches & nicotine gum worked well! Wishing you luck on your trip. Try not to worry too much and enjoy it, but I totally understand how you feel. It is however an opportunity to make new memories, even if mainly for yourself and it sounds like your OH is looking forward to the trip. Good luck
