LONDON, England (CNN) -- The ever budget-conscious boss of Ryanair has suggested the discount airline may start charging passengers for using the toilet on board its flights.
Michael O'Leary said the airline had revived inquiries into whether the airline could install coin-operated toilets on its fleet.
"People might actually have to spend a pound to spend a penny in future," he said in a BBC interview, adding "We're always in Ryanair looking at the ways of constantly lowering the costs of air travel and making it more affordable and easier for passengers to fly with us."
