Not to beat a dead horse, but SOMETHING is going on that affects upgrades and that concerns a lot of Fters.
Before this "enhancement", the system ran at the 3 hour point and worked fairly well. The computer did what it was told and dished out upgrades as per its alogrithmn.

If that last 3 hour run does not occur on some random flights, the whole premise of EUA is in question, since it APPEARS that its up to the gate people to dish out the upgrades, and if they have A9F0 to deal with in a short time, who knows how they will allocate the seats. Remember that CO has stated that it will be by status, then fare code within status.
I don't plan on spending a lot more time on monitoring, but I checked briefly last night. At 17:18 EDT, the 18:40 EWR-SEA flight was A8F0 and the 17:50 EWR-CLE flight was A6F0. Does anybody beleive that there were no silver elites that were going EWR-CLE (hub to hub) that could have been assigned at least 4 of the 6 A seats that were unassigned 32 minutes before flight time.
I think its reasonable for yield management to hold back maybe 2 seats, but not more.
