I'll admit, I've been a bit of an ostrich during discussions up to now of UA flyers on CO-operated flights. I know that as a 1P (matched to CO) I would be viewed as a OP Gold for UDU, but with regard to any other factors since I wasn't going to be flying CO until fall at least, didn't really pay attention. I know that we have Customer Day 1 this week, though it's still unclear what will happen then as opposed to mid-June. Facing flights from SFO to NYC in August, I'm considering flying CO on the way out on the non-stop rather than the PS, as I'm hearing nice reports about these flights up front, and on the way out it won't be an issue to fly into EWR instead of JFK. But I'm really confused about upgrading with miles. As a MP Gold, when am I entitled to upgrade? Only at the 24 hour window? Or at ticketing? If at ticketing, from what I'm reading it's limited fare classes? If at the 24-hour window, mightn't I have already been UDUd? Or should I just not worry and hope that there's not a big fare sale before Wednesday when many questions will be answered by Uncle Jeff and his minions? Appreciate some guidance, even if it's just to the correct thread(s) where I can read it for myself. Between all the threads around (here and TOBB) it's a bit daunting since I've not been keeping up all along. Thanks for the help!
