I don't think so. Did you pick any seats assigned for physically chanllenged persons or otherwise marked for elites?
On a side note, I have had approx. 80 trips on NW in the last couple of years, involving atleast 320 segments, and my seats have been changed just once (change in equipment on a DC9 with no 1C & 1D)
