From passion to global phenomenon
Some use it for work and some for passion, some curious even just to know where that dot that has just crossed the sky is heading. Over time it has become a reference for real-time flight tracking, used by travellers, insiders, media. The reason is simple: it transforms a huge amount of signals and operational data into an instant visualisation that can be consulted via web or app. We are talking about the flight radar most famous free of all, Flightradar24.
Started as an amateur project in 2006 by two Swedish enthusiasts, with the idea of building a network of ADS-B receivers to see aircraft in flight on a map, in 2009 the project opened up to external contributions, allowing anyone with a compatible receiver to send data and extend coverage to new areas. Find out with us.
How Flightradar24 works
To truly understand the “flight radar” experience, one must distinguish between the map and what feeds it. Flightradar24 combines several sources: ADS-B (the signal transmitted by the aircraft), MLAT (triangulation when ADS-B is not available), satellite data and, where necessary, contributions from radar data. To these layers it adds information such as schedules, flight status and route details, thus offering a more complete flight tracker than just the point moving on the screen.
In practice, when you search for a flight by number (e.g. “FR1234”), by route or by airport, the system cross-references the position with the operational data and makes speed, altitude, estimated times and route history readable.
What is it for today: travel, curiosity and work
The most common use is “following a flight”: checking delays, seeing where a family member's plane is, monitoring an arrival when airport information is slow to update. Flightradar24 is also useful for understanding traffic patterns, observe unusual routes, recognise an aircraft model or compare different route options.
Recent news: Santa Tracker and data for Boeing
In recent months, the service has also shown its “pop” and more industrial side. On the one hand there is the Santa Trackerat the end of 2025, Flightradar24 published the numbers of the SANTA1 “mission” between 23 and 25 December, exceeding 33 million follows and reaching peaks close to to 200,000 users contemporary.
On the other hand, in December 2025 it was announced a B2B agreement with BoeingFlightradar24 will provide data services with access to live and historical information based, among other things, on a global network of over 55,000 ADS-B receivers. It is a clear signal that flight radar is not only a “map for the curious”, but also a data infrastructure for digital services and operational analysis.
How to use “flight radar” intelligently
If you want to get reliable information, always look up the flight number and check the date and time slot: many routes are repeated every day. When coverage is incomplete (oceans, remote areas), remember that accuracy depends on the source available at that point. And if you are studying aviation, try comparing several flights on the same route: in a few minutes you will understand seasonality, hubs, “bank” schedules and network logic better than a thousand definitions.
