From the Wikipost:
Quote:- Non-elites on the same PNR benefit from any waived fees for SDC.
ThIs provides an incentive for us to spend cash on my wife's General Member ticket to put her on the same passenger name record (PNR) instead of often redeeming miles for her to accompany me.
I suppose we would need to evaluate both the likelihood and possibility of any such same day change (SDC) as a mere MileagePlus™ Premier Silver. Since most UA flights to Saipan (SPN) are only daily, maybe it's not such a strong motivator after all.
