especially since the marginal cost of even a first class seat would be low The cost all depends on whether or not they would have two spare first class seats to throw away on someone (and his bag) that they are never going to get a dime from again. Even then they could use those seats to offer upgrades to loyal business/coach customers. $37,000 per year doesn't go very far when divided by the price of two first-class tickets. I think this is a classic case of short-term vs long-term thinking.
