In February 2022, during the Russian invasion of Ukraine, the website crashed due to an influx of visitors tracking flights in and around Ukraine. Aircraft located using satellite data are coloured blue on the map, and yellow if located by terrestrial receivers. įrom 3 March 2020, ADS-B data collected by satellite was made available to all users. In November 2015, The Guardian newspaper reported that Metrojet Flight 9268 en route to Saint Petersburg from Sharm el-Sheikh International Airport had broken up in the air based on information available from Flightradar24. Flightradar24 reported that its web traffic increased to around 50 times normal, which caused some access congestion to users. In 2014, it was used by multiple major news outlets following several high-profile crashes: in March after the disappearance of Malaysia Airlines Flight 370, in July after Malaysia Airlines Flight 17 was shot down over Ukraine, and in December when Indonesia AirAsia Flight 8501 went missing.

Flightradar24 came at the turn of the month July–August 2010 as an iOS application. The service received extensive exposure in 2010, when international media relied on it to describe the flight disruption over the North Atlantic and Europe caused by the Eyjafjallajökull volcano eruptions. The service was opened in 2009, allowing anyone with a suitable ADS-B receiver to contribute data. The service was founded by two Swedish aviation enthusiasts in 2006 as and later Flygradar.nu for Northern and Central Europe. It is also used by most major airlines and others in the aviation industry, including Airbus, Boeing, and Embraer. Over 200,000 flights tracked per day, with over 4 million users per day. It is the largest ADS-B network in the world with over 40,000 connected receivers. The Guardian considers the site to be 'authoritative'. The service is available via a web page or mobile device apps. It aggregates data from multiple sources, but, outside of the United States, mostly from crowdsourced information gathered by volunteers with ADS-B receivers and from satellite-based ADS-B receivers. It can also show time-lapse replays of previous tracks and historical flight data by airline, aircraft, aircraft type, area, or airport. It includes flight tracking information, origins and destinations, flight numbers, aircraft types, positions, altitudes, headings and speeds. Flightradar24 is a Swedish Internet-based service that shows real-time aircraft flight tracking information on a map.
