Apologies if someone has addressed this before, but I am wondering if AC would consider playing music during boarding and de-planing? A number of fellow European *A airlines already do this (LX, BD, sometimes LH). If I am not mistaken, NZ does it too. I think this would make the process a bit more pleasant and would help to move people right along (think of why supermarkets and stores play music - it energises shoppers).
