I tend to hang in the YYC lounge and walk down to the gate as late as possible, it may make the gate angents grumpy but this is one of the reasons. They have 5 counters but 2 staff doing all the flights.
If they want me down their early, they need to: 1) board on time 2) really do priority boarding
as 1) is impossible for AC and 2) wont work with their setup I enjoy my coffee or beer in the MLL and come down and be the last guy on the plane.
