While I fear this will turn into another I hate AC/AC Sucks/Don't fly AC pile on, I will none the less toss in my 2 cents.
OP is asking more a question of real tracking rather than luggage handling KPI, though yes. both are valid points
If I recall a few years back, AC's IT system consissted of a dozen or so different systems. I suspect their luggage tracking software cannot speak well with their main system and thus, we do not get the luggage tracking like AA (and others) where you can see where your bag is on the app.
And full disclosure, I'm one of those who believe carry on luggage should be banned and everyone forced to check a bag for every flight. They are dangerous (I am a victim of more than 1 bag falling on/near me in climb) and they slow down the boarding and disembarking process leading to more delays and more missed connections. So I would like to see improvement on this point. But its not a deal breaker for me.
