To play the devils advocate, the lightweight passenger is the one being discriminated against.
All the airline has to sell is payload measured in pounds/kilos. One of the reasons passengers/freight can get bumped at times.
The airline incurs greater costs transporting the heavy pax through greater fuel burn, hence the airline is making a greater profit from the lightweight, and they increase their profit further by selling the payload gained from the lightweight to the freight market. And the profit is further enhanced if the lightweight has excess baggage, even though the total weight pax and bags is far, far less than the heavy guy who has no excess baggage.
In fact the discrimination could be levelled at you because it could be argued you are trying to take a financial advantage over a person because of their weight.
You got that right, they are taking financial advantage over a person because of their weight (light). As a lightweight I'm being screwed over.
