I'm a plat traveling on an S fare EWR-IAH on Wed. I thought I chose my flight strategically for upgrade purposes by choosing CO107 on a 767. F inventory went from F7 to F0 either right before or in the first sweep of EUA's, while all other flights for the day had plenty of F inventory. So I guess it looks like a bad choice after all

Odd thing is I just looked at the upgrade standby list and 14/25 F seats were upgrades. Why would CO clear all those upgrades without leaving even revenue seats open?

The flight right after mine is a 777 with F9, so I'm guessing that might be a better shot. But I'm also guessing they will fill these seats with upgrades prior to 24 hours out. So is there any solution or am I just stuck in Y? I'm guessing it might still be better off to SDC to the 777 as if any seats open up I'd be higher on the list than 767 where it looks like no one will be EUA'd. Anything else I can do to improve my odds?
