You're taking a slippery slope from "out of control to some degree" to "a society where people are discriminated based on things they cannot control (at all)".

You're taking a slippery slope from "out of control to some degree" to "a society where people are discriminated based on things they cannot control (at all)". In the vast majority of cases, obesity can be controlled by a healthy lifestyle. Right now, it's unfair to the skinnier among us, where the prices for overweight luggage and overweight pax do not compare at all. People search all kinds of justification why being obese is ok and needs to receive special attention. I do not argue with that. But: please explain to me why I should pay E100 for 3kg overweight, while the obese person on the seat next to me pays nothing for a 40kg weight difference. How is that fair? Regarding what you call "discrimination": It's really really easy to exempt the obvious (wheelchair etc.) from the bill. No one is asking to become inhumane or discriminate. Where did you get that idea from? This is not about private profit but about the conceived asymmetry in the pricing structure.
