All Nippon Airways (ANA) ran a test to try and convince passengers on their plane use the toilet before boarding.
The theory:
The average human bladder holds about 16 ounces. If 150 passengers relieve themselves during the flight, this would add approximately 139 pounds of waste.
Supposedly, heading to the loo before boarding would save fuel, reduce costs, and reduce greenhouse gas emissions.
No report yet on ANA’s findings regarding the e-flights (“e” stands for “ecology).
