I think airplanes should employ this. If you weigh 300 pounds and have x amount of carry on and the limit is 150 pounds or whatever not only should they be barred from the flight but also forced to leave their carry on behind. If you take up more than one seat that's 2 or even 3 tickets you obese moron. Lard ass creatures. I wonder how they even look at their naked bodies in the mirror. Horror movie material.
