Check out the article:
Japan’s All Nippon Airways (ANA) is asking its passengers to go to the toilet before boarding so it can reduce aircraft weight.
The unusual request is part of an experiment by the airline to cut carbon dioxide emissions.
Japan’s NHK television is reporting that ANA began the one-month experiment today on 42 international and domestic flights.
The airline will place staff near boarding gates to ask passengers waiting for flights to go and use the restroom.
I wonder whether this applies to first and business class passengers as well. 😉
