This tweet recently, from @sampsonian, was very popular with more than 100 retweets. It’s from someone highlighting how the Ryanair website recognises when you’re back visiting them more than once, and tries to charge you more the second time around.
Ryanair exhibit A. Looked up fare yesterday, total £123.00. Returned today and fare is £237.oo. Flushed cookies. Fare is back to £123.00.
It’s a sneaky trick, but it’s nothing new. Your can read an article here on how cookies can cost you money that I wrote back in 2009.
If you’re not sure on how to clear the cookies from your computer if you think you’re losing out because of this, just search Google for the browser that you’re using with the words “clear my cookies” to find instructions. Some browsers will allow you set this automatically as well so that the cookies are cleared each time you close down your browser – but that’s maybe a bit extreme.
