The airline has taken to using a reCAPTCHA system, which are those two word phrases that require you to manually enter them to progress to the next stage of booking a ticket.
Ryanair has introduced the system to put a stop to other websites which crawl through its ticket prices and then display them, acting as a middle-man which Ryanair claims only adds to the price.
"Ryanair will continue to implement measures to get rid of unauthorised screenscrapers and travel agents from our website, so that we can maximise consumer access and continue to improve the response times for ordinary passengers," said Ryanair’s Stephen McNamara.
Such reCAPTCHA options are notoriously difficult and can see people leave a website in frustration, some within the travel industry believe it won't bother potential customers as they are already prepared to buy the ticket.
I suppose whether the system proves a success or not will be something Ryanair will be able to measure pretty quickly, or maybe they will come up with an alternative method to stop middle-man websites.
