Europe's largest budget airline, might start charging passengers for using the toilet while flying, it was announced on Friday.
"One thing we have looked at in the past and are looking at again is the possibility of maybe putting a coin slot on the toilet door so that people might actually have to spend a pound to spend a penny in future," BBC news was told.
"Also, you would have to purchase toilet tissue by the square."
They believe passengers travelling without cash would not be inconvenienced by this move. "I don't think there is anybody in history that has got on board one of our aircraft with less than a pound.
"We can't charge anything for a flush as people would simply not flush."
The firm has a reputation as a harsh cost cutter, offering low headline fares and charging extra for items such as additional luggage, using your laptop, loud fart (inside toilet, half price), or crying baby.
Last week, it announced it was to shut all check-in desks at airports and have passengers check in online instead.
"We also don't serve drinks but there's a water cooler up front with a coin deposit."
"We're all about finding ways of raising discretionary revenue so we can keep from having to raise our air travel costs."
