First two flights of the year that were not international full fare J and I'm 0/2 on domestic upgrades as PPRO.

Side observation. While waiting for my plane to depart SAT I received an email that my upgrade had cleared. Excited I went to check and discovered it was for my flight out to LAX on Thursday. This falls under the 72 hour window for PPRO but the oddity was... I was already booked and paid for in First Class for that trip... So What exactly was upgraded?
