i do not think it pays off to the airlines to make any changes. someone fat will not only need a wider seat but also more gut room. and that means redesigning the space and losing even more room.
and then the weight itself is not easy to judge. our own CB is a big, tall man and i am sure he weighs more than many fatsos, there is just so much of him
and nowadays a pregnant woman easily bulks up and balloons to unbelievable size even in the early stages of her pregnancy when she can fly.
maybe the fat should be allowed to fly at all? let them walk. after a hike from east to west coast they'll be so slim they can take a plane back home
and yes, i am all for hottie stewardesses. in tank tops and short, short shorts.
