Where to Find Live Flight Information

You can track a flight in real time through the airline's website, a flight tracking app, or a dedicated flight tracker website. The airline's own site or app is usually fastest if you have a confirmation number—you'll see gate, boarding time, and delays as soon as they happen. If you don't have a booking number, or you're tracking someone else's flight, use FlightAware, FlightRadar24, or your phone's built-in flight tracker (Apple Maps and Google Maps both have this feature).

Each source shows slightly different information. The airline tells you about your specific flight's status, gate changes, and boarding times. Flight tracker websites show you the plane's actual location on a map, its altitude, and speed. For delays, the airline's system updates first, but flight trackers often catch the delay at the same moment because they pull data from the same radar feeds.

Key Takeaways

  • The airline's website or app shows your gate, boarding time, and delays fastest if you have your confirmation number.
  • FlightAware and FlightRadar24 let you track any flight by airline and flight number, even if you're not booked on it.
  • Flight trackers show the plane's live location on a map, altitude, and speed—information the airline doesn't display.
  • Set up notifications on the airline app or a flight tracker to get alerts when your gate changes or a delay is announced.
  • Delays usually appear on the airline's system first, but flight trackers pick them up within seconds because they use the same radar data.

Using Your Airline's Website or App

Open the airline's app or website and select "Check Flight Status" or "Manage My Booking." Enter your confirmation number (the code from your email receipt) and your last name. The system will show your flight number, scheduled departure and arrival times, current status, and your assigned gate once it's posted—usually 1 to 2 hours before departure.

The airline app will send you notifications if your gate changes, if boarding is delayed, or if your flight is cancelled. Turn on push notifications in the app settings so you don't miss these alerts. If you're at the airport, the app is faster than checking the departure board because it updates in real time and you can see it from anywhere in the terminal.

If your flight is delayed, the airline app will show the new departure time and usually a reason (weather, mechanical, crew delay, or air traffic). This is the most reliable source for your specific flight because the airline controls the data.

Tracking Any Flight with FlightAware or FlightRadar24

FlightAware and FlightRadar24 are free websites and apps that let you track any commercial flight without a booking number. Go to FlightAware.com or FlightRadar24.com, enter the airline name and flight number (for example, "United 447"), and the site will show you the plane's current location on a map, its altitude, speed, and the time it will land.

FlightRadar24 shows more detail about the aircraft itself—the exact plane model, tail number, and how old the plane is. FlightAware focuses more on delays and gate information and pulls data from the airline's system, so it often shows your gate and boarding time if you search by flight number. Both sites update every few seconds when the plane is in the air.

You can also search by tail number (the aircraft's registration, visible on the plane's fuselage) if you know it. This is useful if you want to see where a specific plane is coming from before it arrives for your flight. Both sites have free apps for iPhone and Android that send notifications when a flight lands or is significantly delayed.

Using Your Phone's Built-In Flight Tracker

If you have an iPhone, open Apple Maps and search for a flight by airline and number (for example, "Delta 250"). The map will show the plane's location, altitude, speed, and estimated arrival time. On Android, open Google Maps and do the same search. Both will show you a live map with the plane's position updated every few seconds.

This method is convenient if you already have your phone out and don't want to open another app. The information comes from the same radar feeds that FlightAware and FlightRadar24 use, so it's equally current. However, the phone trackers don't show gate information or boarding times—for that, you still need the airline's app.

What Information Updates First and When

Delays appear on the airline's system first, usually 15 to 30 minutes before the new departure time is announced to passengers. If you're watching FlightAware or FlightRadar24, you'll see the delay almost when ready after the airline posts it because those sites pull from the same data feeds. The departure board at the airport updates at the same time as the airline's app.

Gate changes happen quickly and without much warning. The airline posts the gate 1 to 2 hours before departure, and it can change multiple times in that window. Your airline app will notify you of a gate change if you have notifications turned on. Flight tracker websites don't show gate information—only the airline does.

Once the plane is in the air, all sources show the same information: altitude, speed, and position. The plane broadcasts its location via radar and ADS-B (automatic dependent surveillance-broadcast), which is what flight trackers receive. This data updates every few seconds and is the same whether you're looking at the airline's app, FlightAware, or your phone's map.

Setting Up Alerts So You Don't Miss Updates

Turn on push notifications in your airline's app by going to Settings, finding Notifications, and toggling on alerts for flight status changes. You'll get a notification when your gate is assigned, when boarding begins, and when there's a delay or cancellation. This is the fastest way to know about changes if you're not actively watching your phone.

On FlightAware or FlightRadar24, you can create a free account and "follow" a flight. The site will send you an email or app notification when the flight departs, lands, or is significantly delayed. This is useful if you're tracking someone else's arrival and want to know when to pick them up, or if you want to monitor a flight you're booked on without opening the airline app.

If you're tracking a flight that's several hours away, set a reminder on your phone to check the status 2 hours before departure. This gives you time to see if there's a delay or gate change before you head to the airport. For flights departing soon, check every 15 to 30 minutes because gates and times can shift quickly.

Common Reasons Tracking Information Might Be Delayed or Missing

If a flight tracker shows no data, the flight may not have departed yet, or the plane may be on the ground and not broadcasting its position. Small regional flights sometimes don't appear on flight trackers until they're airborne. Military and private aircraft don't appear on these trackers at all. If you're tracking a flight that should be in the air and it's not showing, wait a few minutes and refresh—the data updates every few seconds but can lag by up to a minute.

The airline's app may show a delay before flight trackers do because the airline knows about mechanical or crew issues before the plane's radar signal changes. Conversely, if a plane is circling due to weather or air traffic, the flight tracker will show that when ready, but the airline may not update the arrival time for several more minutes. Both sources are accurate—they just see different parts of the picture.

If your gate hasn't appeared 2 hours before departure, that's normal—gates are assigned in batches, and some airlines assign them later than others. If it's less than 1 hour before departure and still no gate, check the departure board at the airport or ask at the airline counter. A missing gate this close to departure usually means a delay or a gate reassignment is coming.

Frequently Asked Questions

Can I track a flight if I'm not booked on it?

Yes. Use FlightAware, FlightRadar24, or your phone's map app and search by airline and flight number. You'll see the plane's location, altitude, and estimated arrival time. You won't see gate or boarding information because those are only available to passengers with a booking number.

How often does the flight tracker update?

Flight trackers update every few seconds when the plane is in the air. On the ground, updates are less frequent—usually every 1 to 5 minutes. The airline's app updates whenever there's a status change (gate assignment, delay, boarding). Refresh manually if you're not seeing the latest information.

Why does my airline app show a different arrival time than the flight tracker?

The airline's time is based on the flight plan and may not account for real-time wind or air traffic delays. The flight tracker calculates arrival time based on the plane's current speed and distance, so it's often more accurate. Both will converge as the plane gets closer to landing.

What should I do if the flight tracker shows my plane is delayed but the airline app doesn't say so yet?

The airline usually updates within a few minutes. If the delay is more than 15 minutes and the airline hasn't posted it, call the airline or check the airport's departure board. The flight tracker is reading radar data, which is accurate, but the airline controls the official delay announcement.

Can I track a flight on the ground before it departs?

Not usually. Flight trackers only show planes that are airborne or actively taxiing. Once your plane pushes back from the gate, it will appear on the tracker. Before that, use your airline app to see gate, boarding time, and status.
