Only for the same reason that you probably wouldn't drive a 1982 Buick. Even if the car was in top running order, "its not new". Most people today have a fictation about that. Its true that the older an aircraft gets, the more maintenance it may require. But as long as that required maintenance is performed and it remains economical to do it, there is nothing wrong with the aircraft. Most of Northwests DC-10's have used up only about 25% of their life cycle (in terms of takeoffs and landings). They are realatively cheap to operate and are capabile of operating into the 21st century. Keep in mind that those new aircraft rolling off the Boeing and Airbus production line are extremely expensive. When you consider the cost of the aircraft and the cost of maintenance over its lifetime, there is barely room for any profit.
