I am GM, LAX-HNL Saturday cleared for C+ but several FC open, I called and the agent moved me to FC, she said she was not sure why I was not upgraded since there were plenty of seats open.
I asked about my JFK - LAX flight, 9 Delta One seats still open, no C+ open, I am within the 72 window, and I was told those are going to be gate upgrades. So maybe.....
