Beginning today, Japan's All Nippon Airways will offer women-only bathrooms on most international routes. The designated restroom will be located in the rear section of the plane and be available to all female passengers. Men will be allowed to use it only in emergencies or when there are very few female passengers on the flight. An All Nippon official said "women do not like using shared toilets as men sometimes leave the seat up" and that demand for women-only toilets was especially high among passengers taking long flights. The airline said it received "numerous requests for this service." Sorry guys...there's no plans for a men-only bathroom. BTW, last year the airline made news when it encouraged passengers to use restrooms before boarding to reduce the weight of a plane as part of its "ecological travel on the ground and in the sky" campaign.
