Every AC TPAC I have been on for the past 2 years has arrived late. Typically 30-45 minutes late. It is particularly stressful when I have to transit to a domestic on my return. It's why I often cannot use the cheaper fares through YVR because the connection only allows 90 minutes.
I don't enjoy the AC customer response when my incoming late arrival means I miss a connection. With AC's SOP to overbook, I often cannot obtain a seamless remediation. (And yes, I know a few of you super dooper elites with your nexus and who are on 1st name basis with the staff are taken care of. Unfortunately I am just a fool who paid $5000+ for my ticket and is poorly treated by the airline when it is late.) This is why I have reduced my flying with AC this year.
