The concern had nothing to do with getting a refund. It was only about whether the receipt was accurate. I don’t expect to get a refund when a schedule change lets me pick new flights. I do expect if I’m later sent a receipt it shouldn’t say some portion of that money is going to X if no portion of that money is.

That issue is getting a little off topic, however I do wonder whether, if AC cared more about accuracy concerning that, they would also have thought or bothered to design things so that their system didn’t present Euro prices marked as Canadian prices, which is what’s relevant to this thread. Why not just be accurate rather than inaccurate, whatever one is doing?
