I am still somewhat puzzled by CO's EUA policies for companion upgrades, so sorry if this has been answered elsewhere. I searched but couldn't find it. For background, we were on the same PNR, but apparently not anymore (I don't know why). She's silver and I'm gold. My gf and I in SAT and flying back to SEA tomorrow. For some reason, on the way here yesterday, CO upgraded me but not her. She was NOT happy, and the GA wasn't especially helpful since they'd already given my seat away (to another couple) and were halfway through boarding. Fortunately IAH-SAT is a short flight. I'm not sure how this happened. My understanding is that, being on the same PNR, we should both be treated as silvers, her status. Now on the return I've already been upgraded for IAH-SEA. If I let things be, it's likely that she, as a silver, won't get the upgrade and we'll be flying apart yet again. If I sponsor her for a companion upgrade at the airport, will she be treated as a gold on the upgrade standby list and move up, or will her position remain unchanged? Can I make this request when we arrive at SAT, or do I have to wait until we reach IAH, when they may have given my seat away again?
