Perhaps I should ask this question over here instead of "North America"......

"Under the new DL/NW non-rev plan, if I list on a DL flight to connect to a NW flight (also listed) or vice versa, can the ticket counter agent check my bags all the way thru or do I have to retrieve my bags and re-check them? "


Of course, once the merger is complete and the computer systems are meshed, this shouldn't make any difference........I HOPE!!
