Did a search on this and couldn't find anything, so... We all know that NW has a 5/3/1 window that usually is more likely 6/4/2 unless NWA holds back elite heavy flights for last minute BF UG's, but when does CO release seats?

I'm on a NWA itin with a NW leg and CO leg for Friday, and have already been EUA'd for the NW portion yesterday (which is after the CO segment). KVS shows no changes in fare class avail for the CO part (showing C8 D0 Z0) since Sunday and their seat map shows the same, 8 seats left. When does CO process EUA's for NW? According to their website for Onepass Elite's it's processed "starting" at 5/3/1, but when is it for NW elites? Same?

Thanks in advance.
