Auto upgrade when crediting to other airline?
So, with the h/s/j promo, there's really no reason for me to continue to accrue US EQM this calendar year, even though I have several flights on US. I'm assuming that in order to be eligible for an automatic upgrade, I need to have my US number in the system. Is that right? Is there any way to credit my US flights to another carrier while still preserving the chance of an auto upgrade? I assume this has been asked and answered previously, but I think maybe the search terms I'm trying aren't very good.
