Hi,
Maybe I can offer some suggestions. If both tickets are booked on the CP codeshare, call CP and try to get them to upgrade your travelling companion. Mention to them that you are indeed travelling together, and provide them with the locator# of your reservation. If they can't, or refuse to do the upgrade, then definately try at the gate. As long as you have the correct stickers, you shouldn't have a problem. As long as the agent knows that you're on the same flight, then they really don't care who they're upgrading -- you or your travelling companion.
As of the 2nd of April, CP members are able to book their upgrade on AC operated flights. Just remember; if the booking is on the CP flight number, then call CP to do the upgrade.
Let me know what happens.
