Yep. Like they do on helicopter tours - each of us had to get on a scale before we boarded - and then were seated according to our weight.
Planes should have a few rows of extra-wide seats - costing more but maybe not as much as first class - for plus-sized passengers. Heard plenty of horror stories of someone having to sit next to an obese passenger on a long flight and losing 1/2 their paid-for seat due to overflow.
