On the whole seat issue, You can't just take the seat out and call it good. If the Plane was designed from the factory to have a hundred seats, then the pay has to be a hundred seats, the only way I can see it being different is if a first class is available. The First class would make it impossible to implicate a hundred seats. Therefore the pay would have to based upon the maximum amount of seats that could be installed. So if they took out that one seat, there would have to be something in its place (ie closet.)
