When searching for flights and hotels, users often notice that the same search query can yield different results. This can give the impression that the results are inconsistent or unpredictable. In fact, this is normal behaviour for modern booking systems. They use a variety of factors to generate personalised results for each user.
Why Flight and Hotel Search Results Differ
Differences in search results are not random and do not indicate a system error. Modern booking services operate as dynamic platforms that constantly adapt results to the user. This means that the same query can be interpreted differently depending on the context. As a result, a unique list of offers is generated for each session.
Search results are influenced by various parameters related to the user and their connection:
- IP address and country of connection;
- device type (phone, computer, tablet);
- browser and its settings;
- system language and region;
- user behaviour during the search;
- history of previous queries and views.
All this data together forms the user's overall context. The system uses this to determine which options to display higher up and which lower down. Because of this, the same query can be interpreted differently by the system. As a result, different users may be shown different suggestions, and sometimes even the order or availability of certain options changes.
It is also worth bearing in mind that prices and availability of flights and hotels are constantly changing. This is due to updates from airlines and hotels, demand levels and the number of available seats. Therefore, even for the same user, results may differ when searching again.
Why Clearing Your Browser History Doesn't Always Help Change Search Results
Many users assume that clearing the browser or using incognito mode completely resets search results. In practice, this is not entirely the case, because such actions only affect the device's local data. They do not affect the network level at which user identification operates. Therefore, the system's behaviour may remain the same even after clearing data.
Browser tools do indeed delete cookies, browsing history and temporary files. However, deeper parameters used for user recognition are retained. These parameters are linked not to the browser, but to the network connection and the device itself.
Data that is retained:
- IP address;
- network connection route;
- geographical location;
- device type;
- browser specifications.
In addition, a so-called device fingerprint is used. This is a set of technical parameters that allows the system to recognise the user even without cookies or browser history.
Incognito mode does not hide this data. It merely disables the saving of local information, but does not change how the server perceives the connection. Therefore, the search results often remain similar, even if the user has "cleared" their browser.
How Proxies Are Used for Searching and Booking
Using proxy servers allows you to change the user's network entry point to the internet. Thanks to this, the booking service perceives the request as coming from a different person located in another country or region. This creates a completely different connection context. As a result, the system may generate different search results even for the same query.
Proxies are actively used to analyse and compare search results. They allow you to study how results change depending on geography and connection conditions. This approach is used for both research and practical purposes.
With the help of proxies, you can:
- check available flights from different countries;
- compare routes and connections;
- analyse price differences;
- view available hotels and rooms;
- compare results from different services.
This demonstrates that the same query can yield different results depending on the region from which the connection is made. Sometimes the differences relate solely to price, but in other cases the set of results itself changes. For example, one region might display a direct flight, whilst another shows only connecting flights.
Proxies are also used to analyse changes over time. The same route can be checked via different IP addresses on different days to compare how the results change.
Practical Application and Spaceproxy Infrastructure
In practice, proxies are used to regularly analyse the same routes via different network connections. This helps to track changes in search results and understand how they depend on access conditions. This approach is particularly useful when comparing a large number of routes and dates.
The most common areas of analysis are:
- which airlines appear in different regions;
- which routes and connections are available;
- how prices and fares change;
- which hotels and rooms appear in the results;
- how the order of results changes.
Infrastructure stability is crucial for such tasks. If proxies change frequently or are unreliable, it becomes difficult to compare results. In such scenarios, Spaceproxy is used — a service that provides IPv4 and IPv6 proxies and allows connection via different regions. This makes it possible to simulate different connection points and analyse search results from different "geographical" locations.
This approach helps to examine the same booking system from different angles and gain a more comprehensive picture of the available options. It is also important to use pre-selected or static IP addresses so that the results can be compared accurately. Prices start at approximately $0.09 per IPv6 address for bulk usage. The final price depends on the type of proxy, the region and the number of addresses.
Proxies in the field of flight and hotel bookings are used as a tool to change the user's network context. This allows the system to perceive the request as coming from a different region or from a different user. As a result, the results displayed change.
It is important to understand that proxies do not directly affect how services work. They do not alter search algorithms or interfere with the booking system. Their sole purpose is to change the point of entry to the internet.
This makes it possible to compare different versions of the same search results. It helps you see more options and better understand how the system generates results. Ultimately, the user is able to analyse the search not from a single perspective, but from several different connection contexts at once.
