[silencio]

Virgin America seems to board back to front (after first class, families, etc.) and it tends to be just as time consuming as boarding front to back in my experience. It's even worse because the people sitting back occasionally decide to put their bags in the front above seats that haven't even started boarding that need their own bag space in return. I think boarding any which way with one piece of small carryon or similar will do far more than the order in which you have people board.
