How to identify planes overhead using flight tracking websites
You can see what plane is flying above you in real time using free websites that track aircraft. The most common tool is Flightradar24, which shows a live map of planes in the sky with their flight number, altitude, speed, and destination. You enter your location or zoom to your area on the map, and every aircraft broadcasting its position appears as a small icon. Another option is ADS-B Exchange, which works the same way but includes military and private aircraft that Flightradar24 sometimes filters out.
These sites work because commercial aircraft broadcast their location automatically using a system called ADS-B (Automatic Dependent Surveillance-Broadcast). This is a safety requirement — pilots transmit their position, altitude, and speed several times per second so other planes and air traffic control can see them. The websites receive these signals from ground receivers around the world and display them on a map you can access from your phone or computer.
The process takes seconds: open Flightradar24 or ADS-B Exchange, zoom to your location, and click on any plane icon to see its flight number, aircraft type, where it came from, and where it is headed. You can also search by flight number if you already know which plane you heard.
Key Takeaways
- Flightradar24 and ADS-B Exchange are free websites that show live positions of aircraft overhead, updated every few seconds.
- Aircraft broadcast their location automatically as a safety requirement, and these websites receive and display that data on a public map.
- You can click any plane on the map to see its flight number, aircraft type, origin airport, and destination.
- Military and some private aircraft may not appear on Flightradar24 but often show up on ADS-B Exchange.
- Mobile apps for both services let you track planes from your phone without opening a web browser.
Using Flightradar24 to track specific flights
Flightradar24 is the most user-friendly option for beginners. Go to flightradar24.com, and you will see a world map with plane icons scattered across it. Zoom in to your city or neighborhood by scrolling or typing your address in the search box. Every plane currently in that airspace appears as a small airplane symbol with a colored tail showing its direction of travel.
Click on any plane to open a panel showing its flight number (like "United 447"), the aircraft model (Boeing 737, Airbus A320), current altitude in feet, ground speed in knots or kilometers per hour, and the departure and arrival airports. You can also see the planned flight path as a line on the map. If you want to follow a specific flight, search for its flight number at the top of the page — type "United 447" and the site will highlight that plane and center the map on it.
Flightradar24 offers a free version with all these features and a paid subscription that removes ads and adds features like 3D flight paths and historical playback. For most people tracking planes overhead, the free version is enough.
Understanding what the map symbols mean
Each plane on the map is shown as a small icon with a colored tail pointing in the direction the plane is flying. The color of the tail indicates the type of aircraft or airline, though the exact color scheme varies. Clicking the icon always reveals the specific flight number and aircraft type, so you do not need to memorize colors.
The altitude shown is the plane's height above sea level in feet. A plane at 35,000 feet is cruising at typical commercial altitude. A plane at 5,000 feet is usually climbing after takeoff or descending toward landing. The ground speed is how fast the plane is moving across the ground — this differs from airspeed because wind affects it. A plane showing 450 knots ground speed is moving at roughly 520 miles per hour.
If a plane disappears from the map, it has either landed, climbed above the range of ground receivers in your area, or descended below the altitude where ADS-B signals are reliably received. This does not mean the plane has vanished — it is straightforward no longer broadcasting a signal that nearby receivers can pick up.
Why some aircraft do not appear on tracking maps
Most commercial flights appear on Flightradar24 because they are required to broadcast ADS-B signals. However, some aircraft are filtered out or do not transmit at all. Military planes, government aircraft, and some private jets can disable their ADS-B transmitters or use different systems that public websites cannot receive. Flightradar24 also filters out certain aircraft for security or privacy reasons.
ADS-B Exchange shows more aircraft than Flightradar24 because it does not filter out military or private planes. If you are tracking a military transport plane or a private jet, ADS-B Exchange is more likely to show it. However, ADS-B Exchange has fewer features — it is a simpler map with less information displayed per flight.
Very small aircraft, ultralights, and helicopters sometimes do not have ADS-B equipment at all, especially older models. These will not appear on any tracking map, even if they are flying directly overhead.
Mobile apps for tracking planes on your phone
Both Flightradar24 and ADS-B Exchange offer free mobile apps for iPhone and Android. The Flightradar24 app works identically to the website — zoom to your location, click planes to see details, and search for specific flights. The app is useful if you want to track planes while you are outside or away from a computer.
The ADS-B Exchange app is simpler but also works well for basic tracking. Both apps update in real time as long as you have an internet connection. If you are in an area with poor cell service, the app may lag or fail to load new data, but it will catch up once you have signal again.
Some people use these apps to track planes during flight delays — if your flight is delayed, you can search for your flight number and watch where the aircraft actually is, whether it is still on the ground at another airport or in the air heading toward you.
What to do if you cannot find a specific plane
If you are looking for a particular flight and it does not appear on the map, first check that you have the correct flight number. Flight numbers are usually printed on your ticket or confirmation email and look like "AA1234" (airline code plus four digits). Make sure you are searching in the right time window — a flight that landed an hour ago will not appear on the live map.
If the flight number is correct and the plane should be in the air now, it may be a military flight, a private charter, or an aircraft with ADS-B disabled. Try searching on ADS-B Exchange instead of Flightradar24. If it still does not appear, the aircraft may be flying at an altitude or in an area where ground receivers cannot pick up its signal.
Another option is to check the airline's website or app directly. Most airlines show the current position of your flight in their booking confirmation or app, even if the plane does not appear on public tracking sites. This information comes from the airline's own systems rather than public ADS-B data.
How flight tracking helps during delays
When your flight is delayed, tracking the actual aircraft can tell you whether the delay is because the plane has not arrived yet or because of a ground issue at your airport. Search for your flight number on Flightradar24 and watch its progress. If the plane is still at another airport or in the air, you know the delay is not your airline's fault — the aircraft straightforward has not reached you. If the plane is already on the ground at your airport but your flight is still delayed, the issue is likely a crew problem, maintenance, or a gate assignment delay.
You can also see how fast the plane is moving and estimate roughly when it will land. A plane 200 miles away flying at 450 knots ground speed will arrive in roughly 25 minutes, though this is a rough estimate and does not account for holding patterns or approach delays.
Frequently Asked Questions
Is it legal to track planes with these websites?
Yes. The data these websites display comes from public ADS-B broadcasts that aircraft are required to transmit for safety. The websites straightforward receive and display information that is already being broadcast openly. There is no legal restriction on viewing this data.
Can I track a specific plane over multiple days?
Flightradar24 offers historical playback on its paid plan, which lets you rewind and watch a plane's flight path from hours or days earlier. The free version shows only live data. ADS-B Exchange also keeps historical data but with limited access on the free tier.
Why does a plane sometimes show a different flight number than I expected?
Airlines reuse aircraft throughout the day. The plane you are tracking may have flown three other routes before your flight. The flight number shown on the map is the current flight, not necessarily your flight. Always confirm by checking the departure and arrival airports.
What does it mean if a plane is circling?
A plane circling usually means it is in a holding pattern, waiting for clearance to land. This happens when the airport is congested or weather is affecting landing procedures. The plane will continue circling until air traffic control clears it to descend and land.
Can I use flight tracking to see if my flight is on time?
Flight tracking shows where the aircraft is, but it does not always show whether your specific flight will depart or arrive on time. Use your airline's app or website for official schedule information. Flight tracking is most useful for seeing the actual position of the plane and estimating arrival time based on its current location and speed.
