I have noticed some weird stuff this week. I'm not a regular and am still unsure exactly how the EUA works all the time. I typically at least show on the upgrade list 3 days out as I'm a Gold. However, this week, I wasn't showing up until the day of - maybe the fare I purchased this trip? I was too lazy to call. I ended up being upgraded on 2 of 4 legs, but not until about an hour before takeoff.
