The fastest way to track a flight is to use the airline's website or app with the flight number and date

You can track almost any commercial flight without a ticket by entering the flight number (like UA456 or DL1200) and the date into the airline's website or a free flight-tracking service. The airline's own site gives you the most current information because it pulls data directly from their systems. Most airlines show you the departure gate, actual takeoff time, current altitude and speed, and estimated arrival time—updated every few minutes while the plane is in the air.

If you don't have the flight number, you can search by the passenger's name and the airline (if you know it), or by the departure and arrival cities and date. Most tracking tools will return a list of all flights on that route that day, and you can pick the right one from there.

Key Takeaways

  • The airline's website or mobile app is the most reliable source because it updates directly from their flight systems every few minutes.
  • You need either the flight number or the passenger's name and airline to search; city pairs and dates alone may return multiple flights.
  • Free third-party trackers like FlightAware and FlightRadar24 show real-time position, altitude, and speed using radar data, not airline data.
  • Text or email alerts from the airline notify you of gate changes, delays, and cancellations without checking manually.
  • Tracking stops updating once the plane lands and the gate is assigned, so you won't see ground movement or baggage claim information.

Using the airline's website or app

Go to the airline's homepage and look for a "Track Your Flight" or "Flight Status" link—usually in the top navigation or footer. Enter the flight number (found on the ticket or confirmation email) and the date of travel. Within seconds, you'll see the current status: on time, delayed, cancelled, or boarding.

The airline's tracker shows the departure and arrival airports, scheduled and actual times, current gate (once assigned), and a timeline of any delays or changes. Some airlines also display the aircraft type and seat map. Updates happen automatically every 30 seconds to 2 minutes while the flight is active. If you're tracking someone else's flight, you don't need their ticket number or seat assignment—the flight number alone is enough.

read the airline's mobile app if you'll be tracking flights regularly. Apps send push notifications for gate changes and delays, so you don't have to keep refreshing the website. Most apps also let you save flights as favorites so you can check them with one tap.

Third-party flight trackers and radar maps

FlightAware and FlightRadar24 are free websites that track flights using radar data and aircraft transponder signals rather than airline data. They show the plane's real-time position on a map, its altitude, speed, and heading. These tools work for any commercial flight worldwide, not just one airline, and they often have more detailed technical information than the airline's own tracker.

FlightAware's website lets you search by flight number, route, or aircraft registration. Once you find the flight, you see a live map with the plane's path, a timeline of position updates, and details like the aircraft model and age. FlightRadar24 works similarly but emphasizes the interactive map—you can zoom in and watch the plane move across the screen in real time. Both sites update every 5 to 10 seconds while the plane is airborne.

These trackers are useful if you want to see exactly where the plane is right now, but they don't always show gate information or passenger-facing details like meal service. They also stop updating once the plane lands and turns off its transponder, which usually happens shortly after touching down.

Setting up alerts so you don't have to check manually

Most airlines let you sign up for text or email notifications about a specific flight. Go to the airline's website, enter the flight number and date, and look for an option to "Get alerts" or "Notify me." You'll usually be asked for your phone number or email address. The airline will then send you messages when the flight is delayed, the gate changes, boarding begins, or the flight is cancelled.

Alerts typically arrive within 5 to 10 minutes of a change, so you won't miss a gate reassignment or last-minute delay. This is especially useful if you're picking someone up at the airport—you can go about your day and get a text when the plane is 30 minutes out, rather than refreshing the tracker every few minutes.

Third-party trackers like FlightAware also offer email alerts, though they're less detailed than the airline's own notifications. You can set alerts for delays over a certain length (like 15 minutes or more) so you don't get notified for minor schedule changes.

What information you can and cannot see while tracking

While a flight is in the air, you can see the departure and arrival times, current location, altitude, speed, and gate assignment (once it's been announced). You can also see a history of any delays or cancellations and the reason if the airline has posted one. Some trackers show the aircraft type, tail number, and how old the plane is.

You cannot see passenger names, seat assignments, or which specific passengers are on the flight—that information is private and not available through any public tracker. You also won't see real-time information about what's happening inside the cabin, like whether meals are being served or if the flight attendant call button is lit. Once the plane lands and pulls into the gate, tracking stops updating; you won't see ground movement, baggage claim information, or whether the passenger has exited the aircraft.

Tracking international flights and flights outside the US

The same tools work for international flights. The airline's website will track flights to and from any country it serves. FlightAware and FlightRadar24 cover flights worldwide, including smaller regional carriers and charter flights that don't appear on major airline websites.

International flights may have longer gaps between updates if the plane is flying over the ocean or remote areas with less radar coverage. Some regions have less detailed tracking data available to the public, so you might see fewer position updates on a flight over the Atlantic or Pacific than on a domestic flight. The airline's own tracker is still your best source for passenger-facing information like gate and delay status, regardless of where the flight is going.

What to do if the flight information isn't updating

If the tracker shows "No data available" or hasn't updated in more than 15 minutes, the flight may not have departed yet, or the airline's system may be experiencing a delay in reporting. Refresh the page or close and reopen the app. If the flight is scheduled to depart soon and you still see no data, call the airline directly—their phone line will have the most current information.

If you're using a third-party tracker and it's not showing the flight, double-check the flight number and date. Some regional or charter flights don't transmit radar data, so they won't appear on FlightAware or FlightRadar24. In that case, use the airline's website instead. If the airline's tracker also shows no results, the flight number may be incorrect, or the flight may have been cancelled.

Frequently Asked Questions

Can I track a flight if I don't know the flight number?

Yes. Enter the departure city, arrival city, and date into the airline's website or a third-party tracker, and you'll see a list of all flights on that route. If you know the passenger's name and airline, you can search by name instead. If you don't know the airline, you may have to search multiple carriers or use a tool like Google Flights to see which airlines fly that route.

Do I need the passenger's permission to track their flight?

No. Flight information is public once the flight is scheduled. Anyone can look up a flight number and see its status. However, tracking someone without their knowledge raises privacy concerns, so it's best to let them know you're following their flight, especially if you're picking them up.

How often does flight tracking information update?

Airline websites and apps update every 30 seconds to 2 minutes. Third-party radar trackers like FlightAware and FlightRadar24 update every 5 to 10 seconds. Updates are most frequent while the plane is in the air; they slow down or stop once the plane lands and turns off its transponder.

Can I see where a flight is if it's on the ground?

Once a flight lands and pulls into the gate, tracking stops updating. You can see that the flight has arrived and which gate it's at, but you won't see real-time ground movement or when passengers are exiting. For that information, you'd need to contact the airline directly or ask the passenger.

What's the difference between the airline's tracker and FlightAware?

The airline's tracker shows passenger-facing information like gates, delays, and cancellation reasons. FlightAware and FlightRadar24 show the plane's exact position on a map, altitude, and speed using radar data. The airline's tracker is better for knowing when to pick someone up; the radar trackers are better for watching the plane's journey in real time.
