I flew into Montreal yesterday from the US, and Air Canada neglected to put my bag on the plane. They put it on the first flight today, which landed about six hours ago, and as far as I know the whole time since then it's been sitting waiting for someone to take it through customs so that I can pick it up (or have it delivered). That's pretty much all I've been able to get from anyone: just be patient, it should clear customs "soon" and be ready tonight (or maybe tomorrow morning).
I know in all likelihood I just have to wait, but I'm trying to leave Montreal tomorrow morning and drive a couple hours away, so: given that the bag is probably just sitting down the hall from the exit, is there anything else I could try to get it to me?
