I think what they mean is that if their neighbor is allowed to weight 120kg with 8kg of carry-on and they weight 85kg, they might as well be allowed heavier carry-on. Doesn’t have to be one on one, and of course the carry-on weight limit is also done for a few other reasons, but that seems to be the idea.
To be fair: Carry-on that is weighty is a safety risk. So is me in a window seat with a person that can barely fit into a single seat in the two seats aisle-side from me.
Do you seriously think it would work that way? They wouldn’t charge you a single cent less. Probably charge others more though.
