There was an article a couple years ago about how smart NWA was in keeping its DC-9's. The article said: Since they are all paid for, they do not have to fly certain number of flights per day to break even on fixed cost. They can fly at only the variable cost of the flight and this gives them a lower break even load factor. This keeps the cycles down and extends their useful life. As they approach a heavy check, they seem to be parking them. This also allows them to keep unscheduled spares at their hubs to substitute in case of maintenance problem.
