Where to find live flight tracking

The fastest way to track a flight is through the airline's own website or app. Log in with your confirmation number and last name, or search for your flight by route and date. Most airlines show the aircraft's current location on a map, the gate number (once assigned), boarding time, and any delays—updated every few minutes.

If you don't have a confirmation number, use free public tracking sites like FlightAware, FlightRadar24, or the FAA's Flight Delay Information System. These show every commercial flight in the air, searchable by airline and flight number or by departure and arrival cities. You'll see the aircraft's altitude, speed, and exact position on a moving map.

The airline app is usually fastest for gate changes and boarding updates because the airline pushes notifications to your phone. Public tracking sites are better if you're tracking someone else's flight or if you want to see the aircraft's technical details—tail number, aircraft type, how many times that specific plane has flown today.

Key Takeaways

  • Your airline's website or app shows delays, gate assignments, and boarding times and updates them every few minutes once you log in with your confirmation number.
  • Free public sites like FlightAware and FlightRadar24 track any commercial flight without a confirmation number and show the aircraft's real-time position on a map.
  • Airline apps send push notifications for gate changes and delays, so you don't have to keep checking manually.
  • If your flight is delayed, the tracking map shows whether the aircraft is still on the ground, in the air, or delayed at another airport.

How to read the flight status screen

When you pull up your flight, you'll see several pieces of information. Scheduled departure is the original time. Estimated departure is when the airline now expects to push back from the gate—this changes if there's a delay. Actual departure appears only after the plane leaves the gate.

The same three times appear for arrival. If your flight is delayed, the estimated arrival time will be later than the scheduled time. The difference between scheduled and estimated is your delay. Some airlines also show the reason—weather, mechanical, crew connection, air traffic control—though not always.

Once the plane is in the air, the map shows its current position, altitude in feet, and ground speed in miles per hour. The progress bar shows how far through the flight you are. This information refreshes every 30 seconds to a few minutes depending on the site.

Tracking a flight that's already delayed

If your flight is already delayed when you check, the tracking map tells you why it matters. If the aircraft is still on the ground at the departure airport, the delay is happening there—weather, mechanical work, crew issues, or waiting for passengers from a connecting flight. If the aircraft is in the air but delayed, it's usually because of air traffic control holding it in a holding pattern or slowing it down.

If the aircraft hasn't arrived yet and is coming from another airport, check that incoming flight's status too. Many delays cascade: a plane that's late arriving can't depart on time because it's not there yet. FlightAware and FlightRadar24 both show the aircraft's previous flight, so you can see if it's running behind.

Some airlines let you set up alerts in their app so you get a notification if your departure time changes. This is worth turning on if you're not watching the screen constantly, because gate changes and delay updates happen fast during busy travel times.

Understanding what the map shows you

The flight path on the map is not always a straight line. Aircraft don't fly in a straight line from airport to airport—they follow airways, which are like highways in the sky. These routes are set by air traffic control and vary based on wind, weather, and traffic. A flight from New York to Los Angeles might take a slightly different path depending on the jet stream and which runways are in use that day.

The altitude shown on the tracking map is the plane's current height above sea level, not above the ground. A plane cruising at 35,000 feet is at 35,000 feet above sea level, not 35,000 feet above the terrain below it. Ground speed is how fast the plane is moving relative to the ground, which is different from airspeed (how fast it's moving through the air). A strong tailwind can make ground speed much higher than airspeed.

If you see the plane circling or moving slowly near the destination airport, it's usually in a holding pattern waiting for a runway to open up. This is normal and doesn't mean something is wrong. Air traffic control manages these patterns to space out landings safely.

When tracking shows a long delay or cancellation

If the tracking map shows your flight hasn't moved in hours, or if the airline's website says "cancelled," check the airline's website directly for the official status. Sometimes tracking sites lag by a few minutes, and you want confirmation from the airline before you make other plans.

If your flight is cancelled, the airline's website will show a rebooking option—usually another flight the same day or the next day, or a refund. You can also call the airline's customer service line, though wait times are long during widespread delays. The airline's app usually has a chat or call-back option that's faster than the main phone line.

If your flight is significantly delayed (usually three hours or more for domestic flights in the US), you may be may have access to to compensation depending on the reason and your airline. Weather and air traffic control delays typically don't may have access to. Mechanical issues and crew problems sometimes do, depending on the airline's policy. Check your airline's website for their delay compensation policy, or contact them after the flight.

Tracking tools and what each one does best

Airline apps and websites are best for your own flight because they show gate numbers, boarding times, and seat assignments. They also send notifications. You need your confirmation number to log in.

FlightAware is the most detailed free option. It shows every flight, lets you track by tail number (the aircraft's registration), and has a history of how often that specific plane flies. It also shows delays and cancellations across the entire network, so you can see if your airline is having system-wide problems.

FlightRadar24 is best if you want to see the aircraft's real-time position on a detailed map with terrain and airspace information. It's popular with aviation enthusiasts and shows technical details like the aircraft's type and age.

The FAA's Flight Delay Information System (at faa.gov) shows delays by airport and airline, useful if you want to know whether delays are widespread at your departure or arrival airport before you head to the airport.

What to do if tracking shows your flight is on time

If the tracking map shows your flight is on schedule, you still need to arrive at the airport at the time your airline recommends—usually two hours before domestic departure, three hours before international. Gate assignments can change, and the airline may board earlier or later than scheduled.

Keep checking the tracking map or your airline app up until you board. If a delay develops in the last hour before departure, the airline will notify you through the app if you have notifications turned on. If you're at the airport, the gate display will show any changes.

Once you're on the plane and the door closes, tracking becomes less useful because the airline's in-flight entertainment system and crew announcements will tell you what you need to know. But if you're waiting for someone to arrive, tracking the incoming flight is the most accurate way to know when they'll land.

Frequently Asked Questions

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

Yes. Public tracking sites like FlightAware and FlightRadar24 show any commercial flight without a confirmation number. Search by airline and flight number, or by departure and arrival cities. You'll see the aircraft's position, altitude, and estimated arrival time, but not seat assignments or gate numbers.

How often does the tracking map update?

Most tracking sites update every 30 seconds to a few minutes, depending on the site and how busy air traffic is. Airline apps usually update more frequently than public sites. The map shows the aircraft's last known position, not a live second-by-second feed.

Why does the flight path on the map look different from what I expected?

Aircraft follow airways set by air traffic control, not straight lines. These routes change based on wind, weather, and traffic. A flight from New York to Los Angeles might take a slightly different path each day depending on the jet stream and which runways are in use.

What should I do if the tracking map shows my flight is delayed but the airline app says it's on time?

Trust the airline app—it's the official source. Tracking sites sometimes lag by a few minutes. If there's a big difference, refresh the airline app or call the airline's customer service line to confirm the current status.

Can I track a flight that landed hours ago?

Yes. FlightAware keeps a history of past flights. Search for the flight number and date, and you can see the actual departure and arrival times, how long the flight took, and whether it was delayed. This is useful if you're trying to understand why a connecting flight was missed.
