My last five trips (including one codeshare to UA from Italy) my priority tagged bag has been in the first 10 bags on the carousel. Last 2 flights, my bag was the first through the curtain. On my last trip prior to this current streak, my priority-tagged bag was third to last on to the carousel, long after ALL the other priority bags had come out, so I'm guessing it fell to the side somewhere in the process and was noticed as the handlers were putting things away.
