Going back to the Concierge Key perks:

-I had never been able to get a MIA-BOS upgrade confirmed until 24 hours before the flight and sometimes almost at departure time, but now I get confirmed at the 100 hours prior. (I am also EXP)
- I had a connection with a 4 hour lay over. The CK rep was waiting for me at the door of the plane to take me to the AC lounge. I mentioned that i had become aware of an earlier flight which was departing in 40 minutes. She took me to that gate, got behind the counter and printed me a boarding pass on First. (Under "normal" -non CK status- circumstances, I would have had to ask the agent for the change, she would have placed me on stand by, and then called me after most people had boarded)

So I guess, this is a good start. Bing article is hilarious btw.
