I've had very good luck in splitting PNR's and everyone keeping their seats but you have to call to have this happen because it takes a willing agent. The agent will break the PNR and then simply reassigns the previous seats back to those in your party. I'm not aware if they link the PNR's or not but the PE with companion upgrades have worked using the strategy. We are a family of 5 that splits it to 2 and 3.

Needless to say there is considerable risk associated with this if you have schedule changes. So only split the record 6 or 7 days away and pray the equipment doesn't change on any of the segments to force reseating.
