The Japanese carrier All Nippon Airways has unveiled another questionable toilet etiquette policy following the announcement of new, female-only lavatories to be installed on its jet planes. Only recently, the same airline raised eyebrows in the travel industry by instructing its boarding passengers to visit the bathroom before stepping onto the plane – theoretically as a water and environment saving measure.

The women-only lavatory will be introduced by ANA next month on all international flights. The reason, claims the airline, is that women air passengers have said that a separate toilet was the thing they wished for the most on long flights – behind desserts. Sweet teeth aside, say the ladies, their own toilet is the most attractive service while in the air. No changes will take place to the remaining toilet facilities, and no information has been provided as to the culinary preferences of male passengers, who apparently are unattached to the toilet for a change.

A spokesperson from ANA said the move was a result of customer feedback and that it was hoped the female only initiative would be a point of difference from its competitors. According to the carrier’s findings, most women become uncomfortable with the prospect of taking a seat on the throne when they know there is another person, particularly a male, waiting in the queue behind them. ANA denied the move was a result of men making a mess.
