Flight Radar – track your flights live for free
Looking for a free flight radar? On FlightRadar.Online you can track any commercial flight live, with no registration and no limits. The flightradar shows the real-time position of every aircraft in the world, along with its speed, altitude, route and estimated arrival time. All you need is a computer, tablet or smartphone.
Track a flight – three ways to search
Flight number. Click the search field at the top of the radar and enter the flight number, for example BA283 or FR1995. Select the flight from the list and follow the aircraft live on the map from that moment on.
Airport. Enter the name of an airport or city, for example London, New York or Amsterdam. You will see all scheduled arrivals and departures for the day, as well as flights that have already landed.
Map. Drag the map and zoom in to find any aircraft. Click a plane symbol to start tracking it immediately, or click an airport directly on the flight radar.
What do the symbols on the flight radar mean?
The symbols are simple: yellow symbols are aircraft, blue ones are airports. The size of the symbol matches the size of the aircraft, and different aircraft types have different shapes. Only airports with regular commercial traffic appear on the map; otherwise the radar would be completely covered in blue dots.
Which technology makes live flight tracking possible?
ADS-B. The most accurate data source. The aircraft receives its GPS position from satellites and continuously broadcasts it through its ADS-B transponder. Ground receivers pick up the signal and pass the data to tracking services, so you see the aircraft on the map with virtually no delay. Every aircraft on the map is there because a receiver somewhere picked up its transmission. Follow the signal and you follow the flight: from pushback at the gate to touchdown on the runway.
MLAT (multilateration). If an aircraft has no ADS-B transponder, its position is calculated from the time differences with which its signal reaches several receivers. This works in regions with a dense receiver network, such as Europe and North America.
Position estimation. When an aircraft flies outside receiver coverage, for example over the ocean, its position is estimated from the last known data and the flight plan. On short routes the estimate is very accurate; on long-haul flights it can deviate from the real position.
FlightRadar.Online and Flightradar24 – what is the difference?
FlightRadar.Online is the free flight radar you use right on this page. Flightradar24 (FR24) is the world’s largest commercial flight tracking service, founded in Sweden in 2006 and grown into a worldwide network of receiver stations. FR24 offers a free basic version and paid subscriptions (Silver, Gold and Business) with extra data such as detailed weather, 3D view and flight history. Current prices are listed on the Flightradar24 website. For everyday flight tracking, the free radar on this page is more than enough.
Frequently asked questions
Is flight tracking free?
Yes. The flight radar on FlightRadar.Online is completely free and requires no registration. Paid subscriptions from external services only add extra data for enthusiasts.
Where do I find a flight number to search?
Enter the flight number in the radar’s search field, for example DL83, and select the flight from the list. You will find the number on your ticket, boarding pass or booking confirmation.
Does the flightradar show delays?
The radar shows the aircraft’s actual position and the scheduled and estimated times, so a delay is visible immediately. The reason for the delay is rarely shown; when in doubt, check the airport or airline website.
Why can’t I see some aircraft?
Military aircraft and some government flights are hidden for security reasons. Small aircraft without an ADS-B transponder may be invisible or shown less accurately.
