Not a big fan of Air Canada, but if you are flying out of Montreal (YUL) I find that they have the best airport integration overall by a wide margin. For international flights (excluding the US), my record from drop-off at the airport to sitting at the gate was 15 minutes and it never was more than 45 minutes. Their infotainment system is also pretty good overall, never had a dead screen in +10 flights at this point. But I feel like the average person flying only a few times a year makes this very difficult to evaluate properly. My only experience with WestJet was abysmal, same for Delta. United was ok. Transat (much smaller) was good.
