Its quite simple really. The rules on pricing relate to all airlines and travel providers. They must include all non optional prices.
Strange how Ryanair have now posted they have a "technical problem" that prevents them from showing the prices according to current legislation. Whys isn't this given prominence on their home page in a similar size to their current offer rather than hidden away on a page after you have selected a flight.
I wonder if the IT people will devote as much haste in fixing this issue as they would if the system was down completely...
