My wife has been waitlisted w/an RUC on CVG-LAS for the past 4 months; travel is end of this month.
I noticed that the front cabin seemed to be filling, yet my wife's upgrade hadn't cleared. Agent assured me it was coded correctly
On a hunch I asked an agent to remove the RUC. Viola- an FCM offer for $138. Considering the fare difference between her ticket and the published P fare was over $400, this was an easy choice.
