I wrote in to complain since someone on the upgrade list (myself SE or another SE) should have been upgraded. I recieved an apology & compensation for being by-passed for the employee buddy upgrade. Incidentally, I never saw that gate agent again after this indicent. So in my opinion, YBYL does apply to AC.
