Real-time flight tracking tells you your plane's location, altitude, and expected landing time

When your flight is delayed, the fastest way to know where your plane actually is comes from free flight-tracking websites and apps that pull data from radar systems and aircraft transponders. These tools show you the plane's current position on a map, how high it is flying, its speed, and when it will land — often more current than what the airline's website shows.

The most widely used trackers are FlightAware, FlightRadar24, and Plane Finder. All three let you search by flight number (the two-letter airline code plus the number, like AA 247) or by aircraft registration (the tail number, which starts with N in the United States). You do not need to create an account to use the basic search on any of them.

Key Takeaways

  • FlightAware, FlightRadar24, and Plane Finder show your plane's live location, altitude, speed, and estimated landing time without requiring you to log in.
  • Search by your flight number (airline code plus number) or tail number (the registration on the plane's fuselage, starting with N in the US).
  • If your plane is not showing up on the tracker, it may not have taken off yet, may be on the ground waiting for a gate, or may be too far from radar coverage.
  • Real-time tracking data updates every few seconds and is usually more current than the airline's own delay announcements.

How to search for your flight on FlightAware

Go to flightaware.com. In the search box at the top of the page, type your flight number (for example, United 447 or UA447) and press Enter. The site will show you a list of recent flights with that number; click the one that matches your departure date and time.

Once you open the flight, you will see a map with your plane's current position, a line showing the route it has flown so far, and the route it still has to fly. Below the map, a table shows the plane's current altitude in feet, its ground speed in knots or miles per hour, and the time it took to reach that point. At the top right, you will see the estimated arrival time at your destination airport.

If you know the tail number instead (printed on the fuselage near the back of the plane), you can search for that directly. Click "Aircraft" in the top menu, paste the tail number into the search box, and you will see all flights that plane has made recently.

How to search for your flight on FlightRadar24

Go to flightradar24.com. The homepage shows a live map of all aircraft in the air. In the search box at the top left, type your flight number or tail number and press Enter.

When you click on your flight, a sidebar opens on the left showing the plane's call sign, aircraft type, altitude, speed, and vertical speed (whether it is climbing or descending). The map shows the plane's position and the full route. Scroll down in the sidebar to see the departure and arrival airports, the scheduled times, and how much time remains until landing.

FlightRadar24's free version shows live data but with a slight delay (usually 5 to 10 seconds behind real time). The paid version removes this delay, but for a delayed flight, the free version is usually enough to see where the plane is.

What to do if your plane does not appear on the tracker

If you search for your flight and nothing comes up, the plane may not have taken off yet. Aircraft only show up on the tracker once they push back from the gate and their transponder is active. If your flight is still scheduled to depart in the next hour or two, check back in a few minutes.

If the flight was supposed to depart hours ago and still does not appear, the plane may be sitting at the gate or in a holding area on the ground, where it is still broadcasting its position but the tracker may not have updated yet. Refresh the page or try searching again in a minute or two.

For flights over the ocean or in remote areas far from radar stations, the tracker may show the plane's last known position and then a gap until it comes back into radar range. This is normal and does not mean the plane is lost — air traffic control is tracking it the whole time, even if the public tracker cannot see it.

Understanding what the tracker data means

The altitude shown on the tracker is the plane's height above sea level in feet. Commercial jets typically cruise between 30,000 and 42,000 feet. If your plane is climbing or descending, the altitude will change every few seconds.

The ground speed is how fast the plane is moving over the ground, accounting for wind. A jet cruising at 500 miles per hour through the air may show a ground speed of 550 mph if it has a tailwind, or 450 mph if it is flying into a headwind.

The vertical speed tells you whether the plane is climbing, descending, or level. A positive number means climbing; a negative number means descending. During takeoff and landing, this number changes rapidly. During cruise, it should be close to zero.

The estimated arrival time is calculated from the plane's current position, speed, and the remaining distance to the destination. This estimate updates every few seconds and is usually accurate to within a few minutes, unless weather or air traffic control issues cause a sudden change in speed or route.

Why the tracker sometimes shows a different arrival time than the airline

The airline's website may show an older estimate based on when the flight was supposed to land, not where the plane actually is. The tracker calculates arrival time from real-time position and speed data, so it is usually more current.

If the tracker shows your plane landing 20 minutes earlier than the airline's website says, the airline may not have updated its system yet. If the tracker shows a later arrival, the plane may be flying slower than scheduled due to headwinds or air traffic delays.

Once the plane is within about 100 miles of the destination airport, the tracker's estimate becomes very reliable. Before that, weather or air traffic control instructions can still change the arrival time by 10 to 15 minutes.

Other ways to track your flight

Many airlines show live tracking on their own websites and apps. Log into your airline account, find your booking, and look for a "Track Flight" or "Live Map" button. This usually shows less detail than FlightAware or FlightRadar24, but it confirms the airline's own data.

If you are waiting at the airport, the departure and arrival boards show the plane's status and gate number. Gate agents can also tell you the plane's location and expected arrival time, though they may not have access to the exact altitude and speed that the public trackers show.

Frequently Asked Questions

Can I track a flight if I do not have the flight number?

Yes. If you know the airline and departure and arrival airports, you can search FlightAware or FlightRadar24 by those details. You can also search by the aircraft tail number if you have it. The airline can give you the flight number if you have your booking confirmation.

Is the tracker data accurate?

The tracker data comes directly from the plane's transponder and radar systems, so it is accurate to within a few hundred feet for altitude and a few knots for speed. The estimated arrival time is usually accurate to within 5 to 10 minutes once the plane is in the air, but can shift if weather or air traffic control changes the plane's route or speed.

Can I see what airline owns a plane if I only have the tail number?

Yes. Search the tail number on FlightAware or FlightRadar24, and the plane's details page will show the airline, aircraft type, age, and recent flight history. This is useful if you are trying to figure out which plane is yours.

Why does my flight show as "delayed" on the tracker but the airline has not announced a delay?

The tracker shows the plane's actual position and calculates arrival time based on that. If the plane is flying slower than scheduled or is still on the ground when it should be in the air, the tracker will show a later arrival time. The airline may not have officially announced the delay yet, but the tracker data is real.

What if the tracker shows my plane landed but I have not landed yet?

This usually means the plane has touched down but is still taxiing to the gate. Once the wheels touch the runway, the tracker marks the flight as landed, even though passengers are still on the plane. You will be at the gate within 5 to 15 minutes after the tracker shows landing.
