A co-worker recently mentioned this to me:
He advised that When searching airfares on travel websites, it is a good practice to renew the ip address of the browser.
He said the reason behind this is:
The site would be able to determine if you've been on the site for over a certain amount of time, interpret this as the user going to competitor's websites, and the result would be the site would increase the fares shown.
I cannot find any reliable information for or against this theory. Can someone provide a reliable source of wheter this is true (or not)?
Please do not advise to "just go to snopes.com". I'm looking for a link to information specifically about this question.
