Ryanair chief executive Michael O'Leary had earlier suggested the company examine the possibility of passengers paying to use the on board toilets, a proposal that has since been ruled out and dismissed as a cheap publicity stunt.
"We have received a huge number of ancillary revenue suggestions from passengers and we want more. We are asking passengers to submit their ideas with the most creative winning �1,000 cash," the company's website reads.
The company said that suggestions received so far included charging for toilet paper with the CEO's picture on it, as well as payments for reading the in-flight safety cards and using oxygen masks and emergency exits. There is also a suggested �50 charge so that the cabin crew wears bikinis during the flight.
