Hey everyone, I'd love some advice on what to do. I'm trying to upgrade to business class on CX831 this Friday, but my award booking was dropped by the system yesterday because they were "clearing the waitlists". I've called MPC a few times now and each time they told me that there's no space, and to keep calling back to check upgrade availability. Is this really all I can do?

Also, a dummy booking in I class for the same flight goes through to the payment screen, but seat selection pulls up the seatmap with no available seats. Does this mean the flight is oversold and there's a good chance of op-ups?

Thanks in advance!
