It's funny you should say that. I have no empirical evidence (of course) but to the mark 1 eyeball recently, I have noticed two things that stood out to me (mostly SFO/LHR) that there are fewer 1K/GS, and that the GS that there were seemed to be of the female persuasion. It just stood out in Nov/Dec to me. Again. I am not saying that I have any facts to support this but was an observation and should be taken just as that. Perhaps there is something in it, who knows for sure.
