As airlines began dreaming up one fee after another last year, our running joke became, "What's next? Coin slots on the toilets?" Apparently, yes, that is what's next. Michael O'Leary, CEO of Irish low cost carrier Ryanair, expressed interest in the idea during an interview with the BBC this morning. Says Mr. O'Leary, "Not everyone uses the toilet on board one of our flights, but those who do could help reduce airfares for all passengers." Given the widespread abuse of carry-on allowances now that checked baggage fees are the norm, we shudder to think what effect a toilet fee might have. 

Anyhoo, just be sure to carry a few extra pounds in your pocket the next time you fly Ryanair, as a "meeting in the ladies room" will set you back a whole £1.

Other ideas being tossed around at Ryanair include scrapping airport check-in in favor of online check-ins only, and providing baggage drops. And beginning this October, the airline will introduce their first carry-on luggage only flights.

So, what do you think? Would you fly an airline with a pay-to-go toilet if it meant lower fares? Or is this the lamest idea you've ever heard? Comment below.
