From the DoT site If the airline must substitute a smaller plane for the one it originally planned to use, the carrier isn't required to pay people who are bumped as a result. In addition, on flights using aircraft with 30 through 60 passenger seats, compensation is not required if you were bumped due to safety-related aircraft weight or balance constraints. I'm not sure I understand this exception. Yes it kind of make sense that when it becomes a safely issue the airlines don't have to pay in that they will not play around with safety but isn't it still mostly airlines fault .. lack of proper maintenance or planning. But even it's an accidental case with no fault for the airlines it's also no fault of the customer and you are making individuals pay for the incident and protecting the corporation how does that make sense?
