Thank you for your reply. I read the threads in this forum but they are mostly about redeeming flights not changing award flights. I think my chances are even less than those cases considering that MPC gave me the deadline one month prior to the date of the requested flight to clear the request and I am just a green member.

However, I checked the CP website and found the ticket fare is high for that date. Hope less people will buy tickets.

I noticed that someone in this forum was able to find remaining seat info, but I have no clue where to find that info. It's highly appreciated if someone could advise. I am evaluating the situation to decide whether or not to proceed with other alternatives.

Thanks again.
