Ryanair yesterday challenged Google to take action to protect customers against so-called 'screen scraper' websites who sell Ryanair flights at prices higher than Ryanair sells the flights themselves.

These sites take information from the airline's website and provide it to customers on secondary sites, while charging additional fees.

The Irish airline says that these sites do not make it clear that they are not affiliated to Ryanair.

It released this video explaining its case - and illustrating how sometimes it's flights are sold at higher prices on these third-party websites.

Ryanair has accused Google of taking payments from sites such as eDreams to give its site priority over Ryanair’s own site in search results, it says that this leads to overcharging and other difficulties for Ryanair passengers.

The company's Chief Marketing Officer, Kenny Jacobs has called on passengers to book their flights directly on Ryanair.

Earlier this morning he spoke to Newstalk's Business Breakfast, he described eDreams as a "parasite site."

When asked if the company would be prepared to take Google to court he replied, "If ultimately we think that's the right thing to do - we will do that."

eDreams has released a statement defending its right to sell Ryanair flights.

It reads: "eDreams is perfectly entitled to sell Ryanair tickets, and the tickets of other airlines providing customers with much-needed choice and variety to the flight distribution market."
