I think what I'm going to do is a test change on the AC webpage when briniging up my booking reference. Go through the change without finalizing it just to see what the outcome is. If it is just too much additional cost then it would not be worth it. Just want to save us the aggravation of dragging 4 bags through Canadian immigration and customs twice and then lugging them to and from the airport hotel. I'm really wondering if AC woulld transfer the bags to the morning flight even though it doesn't seem to be their standard policy.
