Where to find live flight information

The fastest way to track a flight is through the airline's own website or app. Every major carrier — American, Delta, United, Southwest, JetBlue, Alaska, Spirit, Frontier — has a tracking tool built in. You enter your confirmation number and last name, and the system shows you the current gate, departure time, arrival time, and any delays or cancellations. This information updates every few minutes.

If you do not have your confirmation number, you can search by flight number and date instead. The flight number appears on your ticket and usually starts with two letters (the airline code) followed by numbers — for example, AA 447 for American Airlines or DL 1205 for Delta.

Third-party tracking sites like FlightAware, FlightRadar24, and Flightstats also show live data for any flight, not just your own. These sites pull information from the same sources airlines use and are free to access. FlightAware and Flightstats let you search by flight number, airline, and date. FlightRadar24 shows aircraft positions on a map in real time, which is useful if you want to see exactly where a plane is in the air.

Key Takeaways

  • Your airline's website or app is the most direct source and shows gate assignments, departure times, and delays specific to your booking.
  • Third-party sites like FlightAware and Flightstats track any flight without requiring a confirmation number, using publicly available radar and airport data.
  • Text and email alerts from your airline notify you of gate changes and delays without requiring you to check manually.
  • Airport websites display real-time departure and arrival boards that show all flights, useful if you are picking someone up or dropping someone off.
  • Flight status can change multiple times in a single day, so check within two hours of departure for the most current information.

Setting up automatic notifications

Most airlines let you sign up for text or email alerts tied to your confirmation number. When you book, the airline usually offers this option during checkout. If you did not select it then, you can add alerts through the airline's website or app — look for a "manage booking" or "flight details" section, then choose how you want to be notified.

These alerts typically cover gate changes, delays of 15 minutes or more, and cancellations. The airline sends them to your phone or email address within minutes of the change, so you do not have to keep checking. Some airlines also let you set alerts for specific events — for example, a notification only if the flight is delayed more than 30 minutes.

Third-party apps like FlightAware also offer notifications. You create a free account, search for your flight, and choose what updates you want. The downside is that these apps do not have your seat number or boarding group, so they cannot tell you about seat assignments or boarding time changes — only gate and departure time shifts.

Using airport departure boards

If you are at the airport or picking someone up, the departure and arrival boards in the terminal show live flight status. These boards update every few seconds and display the flight number, destination or origin, scheduled time, actual time, and gate number. They also show status codes: "On Time", "Delayed", "Boarding", "Departed", or "Cancelled".

You can also find these boards online. Most airports post live departure and arrival information on their websites. Search for your airport name plus "departures" or "arrivals" — for example, "LAX departures" or "JFK arrivals" — and you will find a link to the live board. This is useful if you are not at the airport but want to see what is happening with flights in general, or if you are picking someone up and want to know when their plane actually landed.

Tracking delays and cancellations

When a flight is delayed, the airline updates the departure time on its website and app, and sends alerts if you have them turned on. The delay reason usually appears in the app or on the airline website — common reasons include weather, mechanical issues, crew scheduling, or air traffic control delays. Some airlines are more detailed than others about what caused the problem.

If a flight is cancelled, the airline notifies passengers by phone, email, or text (depending on what contact information they have on file). You can also see the cancellation status on the airline website, the airport departure board, or third-party tracking sites. Once a flight is cancelled, the airline typically offers to rebook you on the next available flight to your destination at no extra charge, or to refund your ticket.

Cancellations often happen in clusters during bad weather or after mechanical problems, so if your flight is cancelled, check the airline's website for other flights that day. Flights later in the day are more likely to depart than those early in the morning, because crews and aircraft have more time to recover from earlier disruptions.

Tracking connecting flights

If you have a connection, track both legs of your trip separately. Enter your first flight number to see if it is on time — if it is delayed, you may miss your connection. Most airlines automatically rebook you on the next flight to your final destination if you miss a connection due to an airline delay, but you need to know quickly so you can plan accordingly.

When you track your first flight, note the actual arrival time and gate. Then check your second flight to see what gate it departs from and when. If your first flight lands late, use the airline website or a third-party site to search for alternative flights to your final destination in case you cannot make the connection. Some airlines let you rebook yourself through the app; others require you to call or visit the ticket counter.

If you are connecting through a major hub like Atlanta, Dallas, Chicago, or Denver, you have more options for alternative flights. If you are connecting through a smaller airport, there may be only one or two flights per day to your destination, so a missed connection could mean staying overnight.

What to do if your flight information is not updating

Sometimes flight information takes time to appear in the system, especially for flights that are several days away. If your flight is more than 24 hours out and the status shows "scheduled" with no gate or time details, that is normal — gates are usually assigned 24 to 48 hours before departure.

If your flight is within 24 hours and the information is not updating, try refreshing the page or closing and reopening the app. Clear your browser cache if you are using a website. If the airline website is slow or down, try a third-party site like FlightAware, which often has information when the airline site is overloaded.

If you still cannot find your flight, double-check the flight number and date. A common mistake is searching for the wrong day — if your flight is tomorrow and you search for today, you will not find it. If the flight genuinely does not appear anywhere, contact the airline directly by phone or through the app to confirm the flight exists and your booking is active.

Frequently Asked Questions

Can I track a flight if I am not the passenger?

Yes, through third-party sites like FlightAware or Flightstats. You search by flight number and date, and the site shows the current status, gate, and estimated arrival time. You cannot see seat assignments or boarding details without a confirmation number, but you can see whether the flight is on time and where it is in the air.

How often does flight information update?

Airline websites and apps update every few minutes once the flight is within a few hours of departure. Airport departure boards update every few seconds. Third-party tracking sites update every one to five minutes depending on the site. The most frequent updates happen in the hour before departure and during the flight itself.

Will I get a notification if my flight is cancelled?

The airline will contact you by phone, email, or text if you have those details on file. You will also see the cancellation on the airline website and app. If you have set up alerts through the airline or a third-party app, you will get a notification, but do not rely on alerts alone — check the website directly if you suspect a cancellation, because alerts can be delayed.

What does "on time" mean for an arriving flight?

On time means the aircraft landed at or before the scheduled arrival time shown on your ticket. It does not mean you can leave the airport when ready — you still need to wait for the plane to taxi to the gate, deplane, and collect baggage. From landing to baggage claim usually takes 30 to 45 minutes on a domestic flight.

Can I track a flight that landed hours ago?

Yes. The airline website and third-party sites keep flight history for several days or weeks. Search for the flight number and date, and you will see what time it actually landed, whether it was delayed, and what gate it used. This is useful if you are checking whether a flight you were supposed to be on actually departed, or if you are disputing a delay with the airline.
