The cost difference between carrying a 175 pound passenger and a 200 pound passenger would not amount to anything measurable.Why don’t we just make sure that everyone boarding the plane pees and poops before hand.( Of course the genius population in our government would decree that they do the business ON the plane BEFORE takeoff) It makes as much sense. Those faculty lounges in Europe are just as dysfunctional as ours I guess. God Save the Republic!
If we all flew naked, there would be a savings in weight also.
