The internet is basically a virtual smorgasbord of travel hacks—between the apps, websites, and services offered, you can pretty much always snag a discounted flight. But as Business Insider points out, there's one equally effective hack that doesn't require nearly as much effort: Clearing your cookies in your web browser.
"A little thing called 'dynamic pricing' means that no, refreshing a window 147,554 times will not make a flight cheaper, but it may actually make the price go up as it changes based on demand," they write. For a refresher, dynamic pricing, also known as surge pricing or demand pricing, is the practice of changing prices based on consumer demand.
But vendors may also take other information into consideration, such as time of day, day of the week, customer location, and even specifics about a customer's purchasing history when determining prices. In other words, the prices offered may be a reflection of what you've purchased in the past, rather than the cheapest possible deals.
"By collecting and analyzing data about a particular customer, a vendor can more accurately predict what price the customer is willing to pay and adjust prices accordingly," explains TechTarget. Most people try to get around this practice by browsing in incognito windows, but BI alleges that clearing your cookies altogether is a much safer bet.
