My partner and I are wailisted for an upgrade to C (using SWUs) on UA 930 SFO-LHR 2 weeks from now. We're on one record; I am 1K, he is 1P. When we made the reservation (6+ months ago) the flight was wide open with no business class seats taken; in the past we've had good luck with getting such upgrades confirmed well in advance. But not this time. With the flight less than two weeks away, and C class filling up, what are our chances? I would obviously prefer BOTH of us to be upgraded, but if there is no chance of that, then ONE upgrade is better than none. Is there any benefit in splitting the record at this time? Does UA automatically split up the reservation, for upgrade waitlist purposes, at some point before the flight? 24 hrs? When we check in? Any insights/tips appreciated!
