I agree, it should be reported by all of us. Personally, I think it is happening a lot. I have only flown Delta 8 times since 1/1/2010 (I am now sending a lot of my business elsewhere these days) but I have seen already 4 times out of 8, a long upgrade list and empty seats in FC.

The first time I thought it was a computer error or something like that. The second time a medallion was allowed to leave the cabin after everyone boarded, talked to the GA, and came back with a brand new FC boarding card! The 3rd and 4th time I was angry and complained to DL (as reported above).
