I've not seen a link yet for this story so here's one:
Ryanair may charge for toilet use on planes - Yahoo! News UK
We all knew this day was coming to be honest. I wouldn't be too impressed if I got on the aircraft and found out that I had to pay £1 - 70p more than Network Rail-managed stations, 80p more than attended loos in town centres - to go to the toilet whilst flying. Do they intend to do this when (or if perhaps) they start cheapo transatlantic flights? Making people on an 8 hour flight pay to use the toilet would definitely not be acceptable...
I will say one thing though - if they're going to make passengers "spend a pound to spend a penny" they better invest the revenues into keeping the toilets spotless - I don't just mean clean, I mean spotless! *grumble grumble*
