Trying to figure out if I have any shot at my UG on DEN-FRA on June 23. I'm actually flying EGE-DEN-FRA with a MUA (Gold status on a U fare) requested for the whole outbound (PP and C). DEN-FRA is currently showing J9 JN9 C9 D9 Z9 ZN9 P9 PN0 PZ0 IN0 I0 O0 ON0 A0 R0 RN0 Y9 YN9 (Looking at EGE-FRA all the way shows less as EGE-DEN has 1 seat in F, not that I care about it) with 22 seats unassigned in C. Looking at UA182 over the last few days in Flight Status has shown C fully booked and/or only a couple seats when each flight shows up 2 days out. I'm assuming this is due to late C purchases, buy-ups and maybe some PZ clearing. I've been looking daily for any PZ space opening up, hoping that maybe I can pull my MUA and reapply. I honestly haven't flown UA on this route for over 10 years due to upgrades being far more likely on LH.
