The Benefits of Clearing Cookies Before Booking 

Travel sites will stop tracking your previous search activities if you wipe out your cookies alongside your browsing history. Here’s why you should do it:

• Websites tend to raise fares by recognizing continual route searches that users perform through the platform.
• A brand new session allows you to see the best available flight prices which have not been affected by personalization through price hikes.
• Using Targeted Ad Prevention you will avoid annoying advertisements that show more expensive flight options.
• Travel sites set different price points based on the device and location of their customers. Accessing your browser with no saved data allows you to view fare prices that have not been influenced by any tracking.
