Interesting you should say that. I called LX and the agent told me that I need to call Air Canada, as it is an Aeroplan ticket. She said if it were an LX ticket, she could advise me, but not now. Even though both legs of this segment are on LX, transfering in ZRH, she could not give me advice. When I asked if she could verify with a supervisor, she then came back and said she believed the luggage could be checked through. "Believed", but not sure. So I am back at square one, it seems...
