I don't understand why airlines aren't just collectively adopting a scale policy.

When you check in: you, and your luggage step onto the scale
And the target allowable weight is set at , say 120 kg


Normals can take normal luggage,
Skinnies can take more luggage
Fatties can't take any luggage , or have to pay for more weight
Super fatties gotta pay more, but can get the extra seat for free or nominal fee(but must declare that while booking)
People with babies , Also equally trated.. again same system , get extra seat if you order it up front.

100% non discriminatory
And no more impacting fellow passengers with the sweaty body parts hanging over the arm rest.

Nobody can argue anymore
Not about luggage weight
not about room on the plane
No more trying to get oversize carry on luggage on the plane
No more wearing extra layers of clothing to reduce luggage weight

Total Weight , Totally Fair
AND much safer for air plane, since they know much closer what their Gross will be.. no more guessing
