Real-time flight tracking tells you a plane's location, altitude, and expected arrival time

When a flight is delayed, the fastest way to find out where the plane actually is comes from free tracking websites that pull live data from radar and aircraft transponders. The plane broadcasts its position constantly, and these sites display it on a map with its current altitude, speed, and the time it will land. You do not need to call the airline or wait on hold — you can see it yourself in seconds.

The most widely used trackers are FlightAware, FlightRadar24, and Plane Finder. All three work the same way: you enter your flight number or search by airline and route, and the map shows you exactly where the aircraft is. FlightAware also integrates with most airline apps, so you may see the map directly in your airline's own tracking feature.

Key Takeaways

  • FlightAware, FlightRadar24, and Plane Finder show a plane's live location, altitude, and speed on a map updated every few seconds.
  • You can search by flight number, airline name, or departure and arrival cities — the flight number is fastest if you have your booking confirmation.
  • The tracker shows estimated arrival time, which updates as the plane moves and as weather or air traffic changes.
  • If a plane is on the ground at the departure airport, the tracker will show that too, which tells you whether a delay is a mechanical issue, crew problem, or weather hold.

How to search for your flight on a tracking site

Open FlightAware.com or FlightRadar24.com in any web browser. At the top of the page you will see a search box. Type your flight number — it looks like "AA1234" or "DL567" and appears on your booking confirmation — and press Enter. The site will show you that specific flight's current position on a map.

If you do not have the flight number, search by airline and route instead. Type the airline name (American, Delta, United) and the departure and arrival cities. The site will list all flights on that route today, and you can click the one that matches your departure time. Once you select it, the map appears with the plane's real-time location.

The map shows a small airplane icon at the plane's current position. Below or beside the map, you will see the altitude in feet, the ground speed in miles per hour, and the estimated time of arrival. These numbers update every few seconds as the plane moves.

What the tracker tells you about why a plane is delayed

If your flight is delayed and you check the tracker, the plane's location tells you what kind of delay you are facing. If the plane is still on the ground at the departure airport, the delay is happening before takeoff — usually due to a mechanical issue, a crew problem, or waiting for a connecting flight to arrive. If the plane is already in the air, the delay is a matter of air traffic or weather at the destination, and the plane will land when it can.

The tracker also shows you how fast the plane is moving. If it is flying at normal cruise speed (around 450 to 500 miles per hour), the delay is not a mechanical problem — the plane is performing normally. If the plane is moving slowly or circling, air traffic control is holding it in a holding pattern, usually because the destination airport is congested or weather is clearing.

Some trackers, including FlightAware, also show you the flight history — where the plane came from before your flight and whether it arrived on time. If the incoming flight was late, your flight may be delayed because the plane and crew are not yet in position.

Differences between the major tracking sites

FlightAware is the most detailed for U.S. flights and integrates with most airline apps. It shows historical data, so you can see whether a plane usually runs late on this route. The free version shows live tracking; the paid version adds alerts and more detailed history.

FlightRadar24 covers more international flights and shows more aircraft overall because it pulls from more radar sources. It has a cleaner map interface and works well on mobile phones. The free version is fully functional for tracking; paid features add alerts and historical data.

Plane Finder is simpler and faster to load on slow internet connections. It shows fewer details than the other two but is reliable for basic "where is my plane" questions. It works on desktop and mobile equally well.

For most readers, FlightAware or FlightRadar24 will answer your question. If one site is slow or not showing your flight, try the other — they pull from slightly different data sources and sometimes one has better coverage than the other.

Why a plane might not show up on the tracker

If you search for your flight and nothing appears, the most common reason is that the flight has not yet taken off and the tracker only shows active flights. Check back in 15 minutes. If the flight is scheduled to depart in the next hour, it should appear once the plane pushes back from the gate.

A second reason is that the flight number you entered is incorrect. Double-check your booking confirmation — the flight number is usually near the top. If you have the wrong number, search by airline and route instead.

Very small regional airlines and some charter flights do not broadcast their position, so they will not appear on any tracker. If your flight is on a regional carrier (like SkyWest or Republic Airways), it may not show up even though it is flying normally. In that case, call the airline directly or check their website for updates.

Using your airline's app instead of a separate tracker

Most major airlines — American, Delta, United, Southwest, JetBlue — now embed live flight tracking directly into their mobile apps. If you have your airline's app installed, open it and find your booking. The app will show a map with the plane's location, often with more detail than the public trackers because the airline has access to its own data.

The airline app also sends you push notifications when the flight status changes, so you do not have to keep checking. If you prefer not to install another app, the public trackers work just as well and do not require you to log in.

Frequently Asked Questions

Can I see a plane's location if it has already landed?

Yes. The tracker shows the flight's history for several hours after landing, including the actual arrival time and gate information. Search for your flight number and scroll down to see the complete flight record. This is useful if you are picking someone up and want to know when they actually touched down.

What if the estimated arrival time on the tracker keeps changing?

The estimated arrival time updates constantly as the plane flies and as air traffic control sends new instructions. If the time is getting later, the plane is being held or is flying into headwinds. If it is getting earlier, the plane is making up time. The tracker shows the most current estimate based on real-time conditions.

Do I need to pay to use FlightAware or FlightRadar24?

No. Both sites offer free tracking that shows everything you need: location, altitude, speed, and arrival time. Paid subscriptions add features like alerts and historical data, but the basic tracking is free and does not require an account.

Can I track a plane if I only know the airline and departure time?

Yes. Enter the airline name and the departure and arrival cities into the search box. The tracker will show all flights on that route for the day, and you can click the one matching your departure time. This is slower than using a flight number, but it works if you do not have your booking confirmation handy.

Why does the tracker show the plane in a different location than what the airline told me?

The tracker pulls live radar data, which is always current. The airline's website or app may update less frequently, especially during busy travel times. The tracker is usually more accurate because it reflects where the plane actually is right now, not where it was 10 minutes ago.
