500 lbs is a very big boy.
If there are 2 empty seats he could “spill” over into, I could see him being flown to where he needs to go.
But, on a full aircraft - his rights to travel should not impinge upon the rights of his fellow travellers from being able to accommodate his girth invading their very limited seat space.
“Kevin Chenais requires round-the-clock oxygen and medical attention.”
I get the impression that this has more to do with his health than his weight....though they are, of course, related.
The problem is he had to be on oxygen 24 yrs. a day. Too many medical problems could happen to him flying six to eight hours. He likely is in bed most of the time. I don’t blame the airlines for not transporting him.
They could put him on a B-52. When is the next run on France?
C-5A, C-17. C124. C130. We once had a great airlift capability.
