Ideally corporations should charge depending on the condition, and on top of that pro-social government should determine which charges are discrimination and which are not, and then compensate discriminating charge difference from the budget. This makes the system transparent and it prevents real incurred costs spilling into unintended areas. E.g. plane won't fly if it is loaded with fuel amount assuming all passengers are slender. Extra fuel is loaded and burned, but currently costs are spread out to other services of the airline. Instead they should be visible and managed specifically I think.
