One of the theories of aeration followed by seeding is that the seed will establish in the edges of the plug holes and that the plugs will cover/topdress the seed as the plugs disolve. Thnksgiving is a bit late for seeding even in many parts of Virginia. If you prepare good seed to soil contact, i'd seed now, and the turf should be established by the end of Nov., then it can withstand aeration with minimal damage. Aeration may not be necessary anyway.
