How Fat is Too Fat to Fly?

I once had to sit next to a man who told me he weighed 550 lbs. The
flight was east coast to west and not very pleasant.

I am retired from a major carrier, and we had a very obese passenger who
could not fit into the lavatory. She releived herself in the air
sickness bag while the f/a held up a blanket trying to give her a little
privacy. I was told the aircraft cleaners had their work cut out for
them. No way would the man in the photo be able to use the lavatory, so
hope he has good kidneys.
