Flight 2240 SFO-JFK last night, the GA was telling people to go away when they tried to board early. ("We're only boarding First Class now." Business, actually, but who cares? They weren't even Sky, must have been Amex holders.)
I boarded about sixth in Sky and the overheads (I was in the front exit row) in my area were already full (from others sitting nearby). Fortunately, the Kryptonium card gave me the ability to use the available bin space in J.
