I have read the thread over and over but I guess I just don't understand how the upgrade lists work.
Yesterday PDX-SJC flight 414 there were 5 people on the list, I was number 3. 3 seats in F available. About an hour before departure there are only 2 people on the list now and I am now
#1 and F is full. How did I go from being number 3 to effectively being
#4 as I didn't get upgraded and someone below me getting upgraded? Gold on a B fare.
I know there is some sort of a hidden list but why would it be a different order than the one visible online and at the gate? Short flight and I did keep my exit row aisle so not a big thing but I just want to understand how this all works.
