We cancelled a flex fare ticket earlier today, when it was bought on-line - largely because an hour after purchase, the fare on that routing (YVR-YYZ-YOW) went down. We could get a full refund, because we were within the 24 hour window of cancelling a flex fare ticket and getting the full refund. She then bought the cheaper ticket (and got upgraded on both segments).

The issue is that the agent is saying that no cancellation email can be sent displaying the refunded amount - she told me to take her word that it happened. She said that perhaps the amount refunded might show up on "manage my bookings" of the AC web site - so I went there - it says that the booking has been cancelled (it does not state that the amount has been refunded); and then it says that any questions on a refund should be addressed to Air Canada!
