I am CM Gold. Something has definitely changed. I was upgraded day of travel for PTY-MEX last Tuesday. At the gate, the agent took away my upgraded seat and said that somebody had paid for an upgrade so they had priority. I pointed out that the Connect Miles terms of service state that I should receive priority as Gold T-48, supposedly those bid for upgrade seats are processed last. The agent told me the bid for upgrades have priority. I was pissed, but what can you do.
