OK I'll be the first to admit that I'm not as experienced as some others here, so this may be a stupid Question, but if I am on a Codeshare flight with a CP flight number that happens to be operated on AC aircraft, what is the pecking order for upgrade stickers? I'm CP Gold and I think that means I can upgrade from any fare class.
Will rules for CP upgrades be made more restrictive to match AC?
As an aside, upgrades are more important to me than free travel - I 've been spoiled and now dread sitting in steerage. Also I have a good stash of sickers with expiry feb 2001 so this is of high interest to me.
