I don't understand the medical condition this boy has but I would have thought a doctor administering adequate sedatives before the flight would be more than enough to get him on the flight on the way home. And if more sedatives were needed through the flight then the parents should be able to cope with this situation.
Aspergers Syndrome is a form of autism. The term is given to people that have some traits of autism but don't have the full thing. If you think of autism as a spectrum of different issues, Aspergers Syndrome is at one end of that only.
Someone with AS generally doesn't like change and loves routine. They're not very good in social settings, and there's a whole load of other non-important stuff.
I'd say AS doesn't have a big role in his issue with flying. He's got some anxiety issues that may be more pronounced because he has AS, but it's not the primary reason he can't fly.
If he's having this many problems though he should probably be seeing a psychiatrist who can help him with his fear of flying and other strategies to control how AS controls him. The worlds leading doctor/researcher of AS lives in Brisbane. I realise he's in Sydney, but he can catch a bus for some help surely.
Is a doctor really required to adminster sedatives? The sceptic in me says that nothing is wrong and someone is just trying to source a business class trip back to the UK out of pity. I hope I am wrong....
Depends what kind of sedatives they are? Some might be too strong for the average person to carry round with them, though I'm sure if they got a doctors certificate and all they'd be fine.
I have the same thoughts - wondering what powers business class has that economy doesn't. Surely you can administer sedatives equally in either cabin. If you were scared to travel, I don't see how being in business would magically overcome the fear.
If you're doped up on sedatives, you're going to sleep equally well in either cabin, surely.
Edit: According to
the Sun the doctor doesn't need to be travelling with them, but they need a business class seat because he apparently needs to lie down when under sedatives. Seems a little odd, maybe there's a medical reason such as swallowing your tongue (not possible) if you're sat upright.
