As a loyal CP traveler who is getting used to all of the nuances of AC I have to say that one great advantage to AC are the new kiosks for checking in at YYZ. Due to my AA/CP/oneworld FF status I am used to not having to stand in line behind a couple of hundred people. I have began to fly AC due to the number of CP flights (southbound) that seem to be canceled at the last minute. I was able to "check-in" and get my boarding pass in under 30 seconds at YYZ this morning. Now if AA could just get theirs to work properly. I will still miss CP though.
