If you have to wait until checkin- the seats are no longer premium! Anyone can have them! I have purchased many a NW ticket as a CO elite, at least on their website, you can't select the WP elite seating. You might be able to then call, but is it really worth it? Many of the elite seats free up the day of departure becuase of upgrades and you should not have too much trouble getting up in the first few rows in coach, unless its a real full flight.
