When you accept a website’s cookies, your browser stores the transmitted information in a designated directory as a cookie.txt file. Every time you open a new page on that website, your browser retransmits that file back to the website’s server, creating a history. The file keeps a running list of pages visited as well as information you’ve entered like your name and address and recent search terms.
Websites have always been able to track user activity on their site, but cookies make the process easier. Cookies are designed to streamline your experience by predicting your future needs based on your previous activity.
Cookies employed by advertising companies generally get the most negative buzz, but that doesn’t mean they’re necessarily bad, they’re just more beneficial to the company than they are to the consumer. These third-party cookies are installed by companies who advertise products on multiple websites in the form of banner ads or similarly integrated posts. They track your browsing habits across the different sites they work with in order to tailor their offerings to your preferences. That’s why you might notice that after you do some online shopping at the Gap, you keep seeing Gap ads all over the internet.
This is a hotly debated issue and one that’s given rise to plenty of misinformation and myths. The short answer is no, there is zero evidence that cookies increase flight prices and searching for flights incognito will not help you find cheaper prices. The Going team performs hundreds of flight searches each day and no matter how many times we conduct the same searches, cookies don’t affect the outcome.
Yes, airline websites will often access an IP address (the string of numbers that identifies a computer’s location and connection to the web) in order to provide accurate location-related information like language, proper currency, and relevant deals.
Because airlines are able to adjust their prices in accordance with a specific market’s makeup (business vs. leisure travelers, relative wealth), some believe that changing your IP address using a VPN (Virtual Private Network, a software program that essentially routes a computer’s internet connection through a different location) will unlock cheaper fares. But, as this 2019 New York Times investigation shows, results can vary depending on the airline, route, and the countries involved.
If you’re concerned about websites tracking your online activity, you can easily delete cookies stored in your browser. However, doing this won’t make a difference when it comes to finding cheap flight deals, and searching for flights incognito won't return different prices.
By going into your browser’s directory, most browsers allow you to either delete individual cookies from specific websites or delete all stored cookies at once. Both options are safe ways to terminate file sharing between your browser and the websites you visit.
Wiping your browser’s history log clean is a harmless procedure, but doing so will not affect your flight search results. Nor will searching for flights in incognito mode.
Deleting cookies will automatically log you out of websites that normally keep you logged in, so you’ll have to re-enter your information the next time you visit. Clearing cookies does not delete usernames and passwords stored in your actual browser, though, as those are supplied by your browser profile and aren’t tracked by external websites.
Instructions for clearing cookies depend on which browser you’re using.
