Agreed - it appeared to be a pretty easy upgrade in my "one flight" experience.
There WAS an off-duty FA by the podium trying to talk the GA into giving her the F seat instead of me as an Elite, if you can believe the nerve.
As I recall after boarding we were the only two people in F, and I can only hope she felt stupid for trying fight me over 16 open seats.
Probably wishful thinking, tho.
