Real-time flight tracking starts with your airline's website or app, or a free tracking service like FlightAware or Flightradar24

The fastest way to track your flight is through your airline's own website or mobile app. Log in with your confirmation number and last name, and you'll see your flight status, gate number (once assigned), departure and arrival times, and any delays. Most airlines update this information every few minutes once your flight is scheduled to depart.

If you don't have your confirmation number handy, you can search by flight number instead. Your flight number appears on your booking confirmation email and your boarding pass — it's usually two letters followed by three or four numbers (like AA 847 or Southwest 1204).

For a view that works across all airlines, FlightAware and Flightradar24 are free websites and apps that show live aircraft positions, altitude, speed, and estimated arrival time. You don't need a ticket to use them — just enter your flight number or the aircraft's tail number (printed on your boarding pass). These services pull data from radar and aircraft transponders, so the information is independent of the airline.

Key Takeaways

  • Your airline's website or app shows the most complete picture: gate number, delay reasons, and rebooking options if your flight is cancelled.
  • FlightAware and Flightradar24 work for any airline and show live aircraft position, altitude, and speed without needing your ticket.
  • Gate numbers usually appear 30 to 60 minutes before departure; if you don't see one, check back or ask at the airport.
  • Set up push notifications on your airline's app so you receive alerts about delays, gate changes, or cancellations without checking manually.
  • If your flight is delayed more than a few hours, call your airline directly rather than relying on the website, because phone agents can rebook you when ready.

Tracking through your airline's app or website

Your airline's app is the most reliable source because it includes information the public tracking sites don't have: the reason for any delay, whether the flight is cancelled, and your rebooking options if something changes. Most airlines push notifications to your phone when your gate is assigned, when there's a delay, or when your flight is cancelled.

To set up notifications, open your airline's app, find your upcoming flight, and look for a "Track Flight" or "Get Alerts" button. You'll usually be asked to choose which updates you want: gate changes, delays, cancellations, or all of them. Turn on notifications in your phone's settings for the airline app so you don't miss the alert.

If you're checking the website on a computer, you may need to refresh the page manually to see updates. The app refreshes automatically in the background, so it's usually faster. Bookmark your airline's flight status page or save the app to your home screen so you can pull it up quickly at the airport.

Using free public tracking services

FlightAware (flightaware.com and app) shows the aircraft's live location on a map, its altitude and speed, and a timeline of when it took off, when it's expected to land, and any delays. You can search by flight number (AA 847) or by aircraft tail number (the registration code on the fuselage, like N12345). The tail number is printed on your boarding pass.

Flightradar24 (flightradar24.com and app) works the same way and includes a 3D view of the aircraft in flight. Both services are free for basic tracking; paid versions add features like historical flight data and alerts, but you don't need them to track a current flight.

These services are useful when your airline's website is slow or down, or when you want to see exactly where the aircraft is right now. They're also helpful if you're picking someone up and want to know how far away the plane is. The data updates every few seconds once the aircraft is airborne.

What to do when your gate hasn't been assigned

Gate assignments usually appear 30 to 60 minutes before departure, sometimes later if the airport is busy. If you're at the airport and your gate isn't showing on the airline's app or the airport's display boards, check back in 15 minutes or ask at the airline's ticket counter. Don't assume your flight is delayed just because the gate isn't posted yet.

If departure time is less than 30 minutes away and there's still no gate, ask an airline agent. They can tell you whether the gate is about to be assigned or whether there's a delay. Agents at the counter have access to information that isn't on the public website yet.

Tracking a flight when it's delayed

When your flight is delayed, your airline's app will show the new departure time and usually the reason (weather, mechanical issue, crew delay, air traffic control). Check the app first to see how long the delay is expected to be. If it's more than a couple of hours, call your airline's customer service number — the phone number is on your confirmation email or on the airline's website — because phone agents can rebook you on another flight when ready, whereas the website may not show rebooking options until later.

FlightAware and Flightradar24 will show you whether the aircraft that's supposed to fly your route is still on the ground, in the air from a previous flight, or delayed somewhere else. This can help you understand whether the delay is because of your aircraft or because of something at your departure airport.

If your flight is cancelled, your airline will contact you by email or phone (the number on your confirmation), but don't wait for that — call the airline directly as soon as you see the cancellation on the app, because rebooking happens in the order calls are received.

Tracking international flights

International flights work the same way: use your airline's app or website, or search FlightAware and Flightradar24 by flight number. The aircraft's position updates in real time even when it's over the ocean, because commercial aircraft transmit their location continuously.

For international flights, time zone differences can be confusing. Make sure you're reading the departure and arrival times in the correct time zone — your airline's app should show both local time at the airport and your home time zone, or you can check the airport's time zone on Google.

Tracking a connecting flight

If you have a connection, track both flights separately. Your airline's app will show both legs of your trip, but you can also search each flight number individually on FlightAware. If your first flight is delayed and you're worried about making your connection, call your airline — they monitor connections and will rebook you automatically if you miss it, but calling gives you a chance to ask about your baggage and confirm your new flight before you land.

If you're checking your connection time, remember that the arrival time shown is when the aircraft lands, not when you're off the plane and at your next gate. Add 20 to 30 minutes for deplaning, collecting baggage (if you need to), and getting to your next gate. If your connection time is less than an hour and your first flight is delayed, ask an agent about your options before you land.

Frequently Asked Questions

Can I track a flight if I'm not the passenger?

Yes. FlightAware and Flightradar24 don't require a ticket — just the flight number or aircraft tail number. Your airline's website requires a confirmation number and the passenger's last name, so you can track someone else's flight if you have those details. Many people track family members' or friends' flights to know when to pick them up.

Why does my airline's app show a different arrival time than FlightAware?

Your airline's app shows the scheduled arrival time and updates it when delays are announced. FlightAware shows the estimated arrival time based on the aircraft's current speed and distance — it's often more accurate once the flight is in the air, but it can change minute to minute. Both are useful; the airline's app tells you what the airline officially says, and FlightAware tells you what's actually happening.

What if the flight number changes?

Flight numbers occasionally change due to cancellations or schedule adjustments. Your airline will send you an email or text with the new flight number. If you don't receive one, call the airline's customer service line — they'll confirm your new flight number and you can search for it on the tracking sites.

Can I track a flight that departed hours ago?

Yes. FlightAware keeps a history of flights for several days. Search the flight number and date, and you can see where it is now, when it's expected to land, and its actual speed and altitude. This is useful if you're picking someone up and want to know how far away they are.

Do I need to pay for flight tracking?

No. Your airline's app and website are free, and FlightAware and Flightradar24 are free for real-time tracking. Paid versions of those services add features like historical data and custom alerts, but basic tracking costs nothing.
