The 1p trick !
This is to get as many people looking at the website,
Its not just about bookings, far from it.
Its designed to get people talking and looking, If a friend tells a friend they tell more and more friends,
Not all will be able to travel where they want to go, however this gets the word out on NEW routes, there are many people out there that dont know that FR fly to, eg, PMI, TFS, FUE, IBZ and MAD. and also all the SKI flights.
when people who dont normaly book many mini breakes and holidays see the normal priced flights Ryanair offer they are still more likely to book a Ryanair flight as many flights, dates and destinations cost alot less than people think, even without the 1p flights
So to sum it up - it gets people looking at what FR have to offer.
