Can someone remind me of a few things, related to cancelled segments and/or involuntary changes to departure/arrival times which are altered by +1 hour?


I know (or think I do) that these types of involuntary changes mean that I can rebook to new different segments for no change fees, but please correct if I'm mistaken.

If I have not flown yet (irrelevant?), with new segments to an existing itinerary, do they recalculate the taxes and then charge a payment if higher, or give a refund if less? My recollection is that they will not charge nor refund in these situations.

If the involuntary change is on the inbound, am I allowed to make changes on the outbound as well?

For these involuntary changes, when is Aeroplan likely to purchase a segment on AC to fix the itinerary, if necessary?

Sorry for these basic questions, but I'm rapidly forgetting the rules and protocols with these things.
