Well, when I checked in at exactly 24:02 before (according to my cell & my computer clocks - it let me go a few minutes early - just kept hitting refresh), there was one open (unassigned) seat for MEM-LAS in F - however, since it wasn't in R-class, I couldn't get the upgrade. For what its worth, Galilelo was showing F3 P3.
Hopefully the standby upgrade will clear & some of you big, bad, platinum folks will misconnect!
