Paying to Go to the Bathroom on Ryanair?

One of my students sent me this article about Ryanair CEO Michael O'Leary's latest suggestion (perhaps in jest!) for raising revenues on his airline's flights. Ryanair, of course, is one of the most successful low-cost carriers in the world. O'Leary has become famous for his bold actions designed to lower costs so as to offer rock-bottom fares. He also has found creative ways to generate revenues from each flight in the form of advertising onboard, duty-free sales, etc. O'Leary is also well-known for a series of brash moves designed to generate free publicity for his airline, while often poking fun at his competitors, particularly the higher-cost European flag carriers. One of the most incredible O'Leary tactics was an advertisement which showed the Pope revealing the fourth secret of Fatima as Ryanair's low fares! You can imagine the outcry that ensued, including from his own Catholic mother. Of course, he also received an unbelievable amount of free publicity from the stunt.
