Live Air Traffic Map: How to Watch Real-Time Flights Worldwide

To watch live air traffic, open a flight tracking map such as Flightradar24, FlightAware, ADS-B Exchange or the OpenSky Network live map in your browser or phone. These services plot aircraft in near real time from ADS-B position broadcasts picked up by thousands of ground receivers, so you can see flights over the whole world, click a plane for its route, altitude and speed, or follow a single flight to its destination.

This guide explains where live air traffic data comes from, how the main live maps differ, how to view flight paths in Google Earth, and why some regions or aircraft are missing from the map.

How live air traffic maps work

Live air traffic maps work by collecting the position messages that aircraft transmit and drawing them on a map within seconds. Most modern airliners broadcast ADS-B (Automatic Dependent Surveillance, Broadcast): a signal that carries the aircraft's GPS position, altitude, speed and identity. Volunteers, airports and companies run ground receivers that pick up these signals and forward them to a tracking network.

Aircraft that only have an older Mode S transponder can still be located through multilateration (MLAT): when three or more receivers hear the same signal, the network calculates the position from the time differences. Some services add radar and other data feeds on top.

This design explains what you see on the map:

• Coverage is dense over land with many receivers (Europe, North America, parts of Asia) and thinner over oceans, deserts and remote regions.
• Positions can lag slightly behind reality because data passes through the network before it reaches your screen.
• Small aircraft without ADS-B or Mode S, and some military flights, may not appear at all.

The main live air traffic maps compared

The four best-known live air traffic maps all show worldwide flights for free in the browser, but they differ in data policy and extras. The table summarises what each service says about itself.

For casual plane spotting, Flightradar24 is the most polished option and includes a 3D view that follows a flight from the cockpit or behind a 3D aircraft model. FlightAware is strong for airport arrivals, departures and delay information. ADS-B Exchange appeals to enthusiasts who want to see every aircraft that broadcasts, and the OpenSky Network is the reference for researchers who need open air traffic data.

How to watch live air traffic around the world

Watching live air traffic around the world takes a minute in any of these services, and no account is needed for the basic map:

1. Open the live map of the service you picked in a desktop browser, or install its official app from the App Store or Google Play.
2. Zoom out to see world air traffic, or zoom into a region or airport to see individual aircraft.
3. Click or tap an aircraft icon to see its flight number, airline, origin, destination, altitude and speed.
4. Use the search box to find a specific flight by flight number, airline, aircraft registration or airport.
5. Use the filters to show only certain airlines, aircraft types or altitudes when the map is crowded.

Tracking a single flight works the same way: search for the flight number shown on the booking, open the flight page, and keep it open to follow the plane until it lands. This is useful when you pick someone up at the airport, and it pairs well with tools such as SeatGuru for choosing a better seat before you fly.

Live flight routes in Google Earth

Google Earth does not draw live air traffic by itself, but you can view real flight paths in it with KML files exported by a flight tracker. Flightradar24 offers KML and CSV export on its Silver, Gold and Business plans, and the history you can export follows the plan: 90 days for Silver, 365 days for Gold and three years for Business.

To view a flight path in Google Earth:

1. Open the flight or aircraft data page on Flightradar24 while signed in with a subscription that includes exports.
2. Click the KML button next to the flight and save the file.
3. Open the file in Google Earth (desktop or web) to see the route in 3D.

Each Flightradar24 KML file contains a Route folder with an animated playback of the flight and a Trail folder with the colored flight path, and you can combine several files in Google Earth. This is the modern version of what ghacks covered in 2008, when the Flightwise service loaded hourly snapshots of US flights into Google Earth.

Flightwise still exists, but today it is mainly a flight planning and IFR flight tracking service for pilots rather than a live world air traffic map.

Why some flights do not show on the live map

Flights disappear from a live air traffic map mostly because no receiver can hear them or because the service chooses not to display them. Over open ocean and remote land there are few or no ground receivers, so a plane may vanish after leaving the coast and reappear when it approaches the other side.

Other common reasons:

• The aircraft has no ADS-B transmitter, and too few receivers are nearby for MLAT.
• The flight is military, government or private, and its operator has asked for it to be hidden; services handle such requests differently, which is why ADS-B Exchange stresses that it shows data unfiltered.
• The flight has not departed yet, or its transponder is switched off on the ground.

If your area has poor coverage, you can improve it yourself. Flightradar24, FlightAware, ADS-B Exchange and OpenSky all invite people to host a receiver, and FlightAware, for example, rewards data feeders with a free Enterprise account.
