It's most definitely an AC flight lol. My first stop would be LHR or CDG. The second stop before I go to NYC is YUL or YYZ. I have a choice of either/or with that connection as well, but I'm focused on the LHR vs CDG layover. I didn't include the details of the second stop options in my original post as it seems irrelevant to my question.
