I've not booked Ryanair, but all the other airlines I've flown with make it quite clear and the information is easily available on their websites as to exactly what the extras like PSC and taxes are. These are additional charges for someone else collected by the airline involved. There is no reason they should all be included in one fee for travel- that hides the nature of the charges from the customer. It is good the customer is made aware of the other charges being made to him and exactly what is being charged for the air travel that he wants!
