I have an experiment I'd like to try but will need the assistance of another CO elite member. I've got a companion accompanying me on a few NW segments of my flights from Asia. Because we're not on the same PNR (record locator), NW refuses to extend the priority seating to my companion. I can grab a preferred seat b'cos of my elite status.

What I'd like to do is to switch the NW PNR to recognize another CO elite FF, grab adjacent an adjacent seat to me, and then remove the CO elite FF number. I cannot switch my companion's FF to mine so b'cos I'm already on that flight. I'll send instructions privately.

Can anybody assist?
