FEasibility of long haul with elderly relative with mobility issues
My ninety-*cough* year old Granny has expressed a wish to return from the UK to Aus, and spend her twighlight years with her sons and their familes who all live there. However she is a) entirely immobile and b) insisting that she must fly. Short of a Medivac flight (we'll keep buying the lottery tickets...), is there any way of getting her back home on a standard commercial flight? Our main concern is that whilst she isn't entirely incontinent, she would need help with "personal functions" and there simply isn't room for manouevre in an aircraft loo (she'd need to be lifted on and off - amongst other things involving at least one helper).
Can anyone advise on the practicalities or is it a complete no-go? We've promised we'll take her request seriously and would try our best to find a way for her to go home. This community is my best shot.
She's refused to consider going by cruise liner, on the the grounds that she can't swim and is terrified of the ocean. Our protestations that she probably couldn't fly unaided either, are cutting no ice!
Thanks for any advice.
