I call BS too, if I were AA number 1 traveler lets say out of ATL, I would have no reason to tell anyone (excpet my wife) , what is the point, does it make you feel better about yourself.
When the old EXP tags had the million miles mark, a few times on the bus in LHR switching terminals, I have had other passengers ask me about them, I just tell them that it taken a very long time to get there and leave it at that
