no price comparison ?
Simple.
Ryanair is not THE low cost airline, it is AN aggressively marketed airline trading on the principal that if you shout loud enough often enough people will believe the message.
The alternatives more often than not work out cheaper as our recent holiday demonstrated clearly.
Even without all the hidden charges FR was 3 TIMES the price of the booked seat, wine with meal, 30kg baggage allowance alternative.
Price comparison sites do what they say they do and the last thing Ryanair want is the truth coming out.
Headline fares of 0.01 euro one way are fine, but dig deeper and the picture is not always as Ryanair would have everyone believe.
