Parking the DC-9's is not rumor. NWA's premerger fleet plan for 08 had them being reduced from over 100 aircraft to 68. Just a few years ago there were 160 DC-9's. Recent changes bring that number down to around 60 at the end of the year. That is a loss of over 40 aircraft this year. I don't think you could phase them out any faster if you wanted to.
