You can identify planes overhead using free flight-tracking websites and apps that show real-time aircraft location, altitude, and destination
When a plane passes over your house, you can find out what it is within seconds using ADS-B tracking sites. These websites receive signals that aircraft broadcast automatically — the same signals air traffic control uses. The most popular free options are Flightradar24, ADS-B Exchange, and RadarBox. You enter your location or zoom to your area on a map, and the site shows every aircraft in the sky with its flight number, aircraft type, altitude, speed, and where it came from and where it's headed.
The reason you can do this is that commercial aircraft transmit their position constantly. This data is public and unencrypted. Private planes and military aircraft often do not broadcast, so you will see gaps in coverage — but most of what flies over populated areas is commercial traffic, and you will see it.
Key Takeaways
- Flightradar24 and ADS-B Exchange are free websites that show live aircraft positions, flight numbers, and destinations using publicly broadcast signals.
- You can identify a plane by zooming to your location on the map and clicking on the aircraft symbol to see its flight number and aircraft type.
- Military jets, private planes, and some government aircraft do not broadcast their position, so not every plane overhead will appear on these sites.
- Flight-tracking apps work on phones and tablets, so you can check what is flying over you without opening a computer.
How to use Flightradar24 to identify planes overhead
Go to flightradar24.com and allow the site to use your location, or type your city name in the search box. The map will center on your area and show aircraft symbols in real time. Each symbol is a small airplane icon colored by aircraft type — commercial jets are one color, helicopters another. Click on any aircraft and a box appears showing the flight number (like "United 447"), the aircraft model (like "Boeing 737"), current altitude, speed, and destination airport.
The flight number is the most useful piece of information. You can search that number on the airline's website to see if the flight is delayed or on time. If you want to know why planes are flying over at odd hours or in patterns, the destination airport often explains it — a plane heading to a major hub like Atlanta or Chicago is likely a connection flight, while one heading to a smaller airport may be a regional service.
Flightradar24 also shows historical flight data. If you saw a plane at a specific time but did not catch the flight number, you can click the time slider at the bottom of the map to rewind to that moment and see what was flying then.
What ADS-B Exchange and RadarBox show that Flightradar24 does not
ADS-B Exchange and RadarBox are alternatives that sometimes show aircraft Flightradar24 does not, because they receive signals from different ground stations. ADS-B Exchange is run by volunteers and has no paywall — all features are free. RadarBox has a free version with basic tracking and a paid version with more history and alerts.
The main difference is coverage. If you live near an airport or in a dense urban area, all three sites will show nearly identical data. If you live in a rural area or near a military base, one site may show more traffic than another because it has more receiver stations nearby. Try all three and see which one shows the most activity in your area.
None of these sites show military aircraft reliably. Fighter jets, transport planes, and helicopters operated by the Department of Defense usually do not broadcast their position, or they broadcast it with a delay. If you see a military jet overhead but it does not appear on any tracking site, that is normal.
Why planes fly over the same route at the same time every day
Commercial aircraft follow established flight paths called airways. These are invisible highways in the sky, designed by air traffic control to keep planes separated and to route them efficiently between airports. If you live under a major airway, you will see planes at similar altitudes and times every day, especially during peak travel hours in the morning and evening.
Planes also stack up near busy airports. When an airport is congested, aircraft are told to circle at different altitudes while they wait for a landing slot. This is called a holding pattern. If you live near a major airport, you may see planes circling overhead for 15 to 30 minutes, especially in the afternoon. The flight-tracking site will show the aircraft's altitude — if it is descending slowly and circling, it is likely in a holding pattern.
Noise complaints about repetitive overhead traffic are common near airports. If the pattern bothers you, the airport's website usually has a noise complaint form. Many airports have preferential runway use policies that change based on wind direction and time of day, so the flight path may shift seasonally.
How to tell if a plane is in trouble or just delayed
A plane flying slowly, circling, or descending unusually fast does not necessarily mean it is in trouble. The most common reason for unusual flight behavior is a delay on the ground — the aircraft may be holding at altitude because the airport is congested, or it may be descending more steeply than usual to make up time.
On the flight-tracking site, check the aircraft's speed and altitude trend. A plane descending at a normal rate (about 2,000 feet per minute) is fine. A plane descending much faster (4,000 feet or more per minute) is unusual but not necessarily an emergency — pilots do this intentionally when they need to lose altitude quickly. A plane that suddenly stops moving on the map usually means the site lost the signal, not that the aircraft stopped.
If you are genuinely concerned about an aircraft overhead, the flight number on the tracking site lets you check the airline's website for status. If the flight shows as on time or delayed, the plane is operating normally. If you see an aircraft making an emergency descent or hear emergency vehicles, call 911 — do not rely on flight tracking to determine if help is needed.
Mobile apps for tracking planes on your phone
Flightradar24, RadarBox, and ADS-B Exchange all have free mobile apps for iOS and Android. The app versions work the same way as the websites but are faster to open and can send you notifications when specific flights pass overhead. You can set up alerts for a particular flight number, airline, or aircraft type.
The Flightradar24 app is the most popular and has the most polished interface. The free version shows live tracking and basic aircraft information. The paid version adds features like 3D flight paths and detailed aircraft history, but the free version is enough to identify what is flying over you.
Apps are useful if you hear a plane and want to identify it quickly without opening a browser. Open the app, zoom to your location, and click on the aircraft overhead. You will have the flight number and destination in seconds.
Why some aircraft do not show up on tracking sites
Military aircraft are the most common planes that do not appear on public tracking sites. The U.S. military, foreign militaries, and government agencies can disable the broadcast signal or request that tracking sites not display their aircraft. If you see a fighter jet, cargo plane, or helicopter with military markings that does not appear on any tracking site, this is why.
Private planes are required to broadcast their position, but many owners pay for a service that hides their aircraft from public tracking sites. This is legal and common among wealthy owners and business jets. If you see a small plane overhead that does not appear on the tracking site, it may be a private aircraft with a hidden signal.
Older aircraft may not have modern ADS-B equipment and will not appear on tracking sites at all. This is rare in the United States because the FAA required all aircraft to have ADS-B transmitters by 2020, but some older planes still operate without them.
Frequently Asked Questions
Can I see where a plane is going after it lands?
Yes. On Flightradar24, click on a landed aircraft and scroll down to see its flight history. You can see where it came from, how long the flight took, and what time it landed. The site keeps this data for several months, so you can look up flights from days or weeks ago.
Why do planes fly over my house at 3 a.m.?
Planes fly 24 hours a day because airports operate around the clock. Overnight flights are often cargo planes, red-eye passenger flights, or aircraft being repositioned to another airport. Check the flight-tracking site at that time to see the flight number and destination — that usually explains why it is flying at an odd hour.
Is it legal to track planes with these websites?
Yes. The data comes from public broadcasts that aircraft are required to transmit. The tracking sites are legal in the United States and most countries. You are not hacking anything — you are reading information the aircraft is already sending out.
What does it mean if a plane's altitude changes suddenly?
Sudden altitude changes are normal. Planes climb and descend as part of their flight plan, and air traffic control may order them to change altitude to avoid other traffic. A sudden drop in altitude near an airport means the plane is beginning its descent to land. A sudden climb usually means the pilot is avoiding weather or following a new instruction from air traffic control.
Can I find out who owns a private plane?
The FAA maintains a registry of aircraft owners, but it is not searchable by the public for privacy reasons. You can search by tail number (the registration number on the fuselage) if you have it, but the registry does not show owner names for most private aircraft. Some flight-tracking sites show tail numbers, which you can use to look up the aircraft type and age, but not the owner.
