I have tried calling, but the problem with calling and having no ammo or reliably search data is that you're at the mercy of whatever they tell you. I've called KF probably 10 times total, for this and in other scenarios. The first answer I ALWAYS get is "no there's nothing". Whenever I've had that kind of experience with Aeroplan, I can usually fire back and say "oh really, even this flight on this exact date and time, then connecting to this flight". The reply is usually like "oh yea, there it is". Meanwhile I search up 1 way MDE-CAI and get absolutely nothing, not even a bad routing, on every single day I search. I call, I get told the exact same thing.
