(CNN) Ryanair, which is based in Dublin, Ireland, and bills itself as "Europe's first and largest low fares airline," is mulling a plan that would require travelers to pay either 1 euro or 1 British pound (about $1.33 or $1.52) for using the bathroom on flights lasting one hour or less.

The plan, titled "Ryanair Cost Saving Proposal," was published in the airline's inflight magazine. The carrier said it is working with Boeing to develop a coin-operated door release so that when nature calls, passengers would need to deposit the change before being able to use the facilities.
