It is no news that people pay additional flight fees based on the fare class, i.e., First class, Economy class, etc. But do you know that you can be sitting next to a passenger on an airplane, but he paid a lesser ticket fee than you? Yes! It’s a thing. Airlines websites and search engines used for booking flights have use cookies to know whether or not you’ve been searching for flights on their site (and potentially other sites).

Ever wondered why whenever you search for something you want to purchase on Google, your social media is suddenly filled with pictures of that thing you anonymously searched for. This is possible because of their access to your cookies. Airline websites do the same thing. For example, if you go on an airline website to search for their ticket prices, the next airline website you visit will most likely use your search result to optimize their own expense. These airline websites change their prices based on your previous search because the search history has given them an idea of how much you are willing to pay to get the sit you want or the ticket itself. Hence, they use this marketing strategy to determine how much their tickets see sold.

However, airlines charge different fees based on the location because they use a dynamic pricing system. The dynamic pricing system allows the price on a website to increase or decrease based on your location. For example, booking your flight ticket from the US might give you an extravagant offer based on how the country is seen internationally. In this case, the same amount charged in the US will not be charged when buying the same ticket from India or other low affluence countries. The airline carriers have a way of determining this and then setting their price.

Therefore, a VPN is needed to help you switch IP addresses. VPN would also help you clear and block cookies that give intruders access to your search history.
