I know it has been debated before, but such a policy as Virgin's is enough to keep me from flying with them. If I have a window seat I want autonomy with regard to my window shade. I don't accept that airlines have the right to refuse passengers wanting their blinds open. All passengers are provided with eye shades to keep light out if they so wish. Many claustrophobic passengers tend to favour window seats so that they can look outside (even at night).
