Does incognito mode work for flights?" It's a question that many travelers ask, hoping to find a secret way to snag lower fares. The theory is that using incognito mode prevents airlines and travel sites from tracking your searches and hiking prices accordingly. While incognito mode does stop cookies from being saved, it doesn't hide your IP address or other tracking mechanisms. Therefore, while it might help in some cases, it's not a foolproof method for cheaper flights. For the best results, use a combination of tactics such as comparing prices on different platforms, using fare tracking tools, and booking at strategic times.
