Similar situation in Detroit this past week - however the GA noticed (I assume) that most of the passengers had jumped into line so she amended her statement to First Class and Diamonds first then onto Platinums and so on.
I think this is the best way to handle the situation at this point - with about everyone except the once or twice a year fliers getting into the sky priority lane these days it can get a little overwhelming as all of those reading this most likely know.
