Flying YYZ to YVR on AC115 yesterday. Checked in a piece of luggage where the AC agent affixes the Priority tag. When I get to YVR, my luggage doesn't come out with the all of the "Priority" luggage. It comes out much later with the rest of the plebeians. Looking at my luggage, the Priority tag was ripped off (only the tip of the tag remain). So what gives? This isn't the first time too. AC or GTAA staff can do this to spare themselves work or something? Pretty classless if you as me. The priority baggage handling is already sketchy at best, and now this?
