Check your flight status directly with the airline
The fastest way to learn about your flight is on time is to go to your airline's website or app and enter your confirmation number and last name. Most airlines show you the current gate, departure time, and any delays in real time. This information updates every few minutes, so you get the most accurate picture of what is actually happening at the airport.
You can also call the airline's customer service line — the number is on your booking confirmation or on the airline's website. Have your confirmation number ready. A representative can tell you the current status and answer questions about what caused any delay. This takes longer than checking online, but it is useful if you want to ask about rebooking or compensation.
Key Takeaways
- Your airline's website or mobile app shows real-time gate and departure information and updates every few minutes.
- Flight tracking websites like FlightAware and FlightRadar24 show you the aircraft's actual location and speed, which reveals delays before the airline updates its system.
- Delays under 15 minutes often do not appear in the airline system until the flight is already late, so tracking the aircraft itself is more reliable for early warning.
- Airports publish their own delay information on departure boards, which you can sometimes view online through the airport's website.
- Text and email alerts from your airline or a tracking app notify you automatically when your flight status changes, so you do not have to keep checking.
Use flight tracking websites to see where the plane actually is
Flight tracking sites like FlightAware and FlightRadar24 show you the real location of the aircraft, its speed, and its estimated arrival time. These sites pull data from radar and aircraft transponders, so they often catch delays before the airline's own system does. Search for your flight number (it starts with letters, like UA456 or DL789) and you will see a map with the plane's current position.
This method is especially useful if your flight is delayed by less than 15 minutes. Airlines often do not update their systems until a delay is confirmed, but a tracking site will show you that the plane is still on the ground or moving slowly toward the airport. You can watch the aircraft approach in real time and get a sense of when it will actually land, rather than waiting for an official announcement.
Both FlightAware and FlightRadar24 are free to use on their websites. FlightAware also offers a mobile app with push notifications, so you can get alerts when your flight takes off or lands without checking manually.
Check the airport's departure board online
Many airports publish their live departure boards on their websites. Search for the name of your departure airport plus "departures" and look for a link to the live board. You will see your flight number, scheduled departure time, current status, and gate number. This board updates in real time and shows delays as soon as they are posted.
Not every airport makes this information available online — some only show it on screens in the terminal. If your airport does not have an online board, you can still call the airport's main information line and ask about a specific flight. Have your flight number and airline ready.
Set up automatic alerts so you do not have to keep checking
Most airlines let you sign up for text or email notifications about your flight. Log into your booking on the airline's website and look for an option to add alerts. You will get a message when your flight is delayed, when the gate changes, when boarding starts, and when the flight takes off. This way you do not have to refresh the website every 10 minutes.
Third-party apps like Hopper, Google Flights, and FlightAware also send notifications. If you booked through one of these apps, you may already have alerts turned on. Check your app settings to make sure notifications are enabled and that you have the right phone number or email address on file.
Understand what different delay statuses mean
When you check your flight status, you will see one of several labels. On Time means the flight is expected to depart at the scheduled time. Delayed means the departure time has been pushed back, and the system will show you the new time. Boarding means passengers are currently getting on the plane. Departed means the plane has left the gate.
Sometimes you will see Cancelled, which means the flight is not running that day. If this happens, contact your airline right away to rebook on another flight or get a refund. Diverted means the plane landed at a different airport than planned, usually because of weather. If your flight is diverted, the airline will arrange ground transportation or a connecting flight to your original destination.
Know the difference between gate delays and actual delays
A gate delay means the plane is ready to go but cannot push back from the gate yet — usually because the runway is busy or air traffic control is holding flights. The aircraft may sit at the gate for 20 or 30 minutes and then take off without changing the official departure time. This is not the same as a mechanical delay, where the plane itself has a problem and the departure time gets pushed back.
If you see your flight is delayed but the gate status shows "Boarding" or "In Progress," the delay may be short. If the status shows "Delayed" with a new departure time, the airline has confirmed the delay and you should plan accordingly. Flight tracking sites will show you whether the plane is actually moving or still on the ground, which helps you understand how serious the delay is.
What to do if your flight is delayed
Once you know your flight is delayed, contact your airline to find out the reason and how long the delay is expected to be. If the delay is more than a few hours, ask whether the airline will provide a meal voucher, hotel room, or rebooking on another flight. Policies vary by airline and by how long the delay is.
If you are at the airport, go to the airline's ticket counter or gate agent and ask in person. If you are still at home, call the airline's customer service line or use the chat feature on their website. Keep your confirmation number and boarding pass handy. Take screenshots or photos of the delay status in case you need to file a claim later.
Frequently Asked Questions
How often does flight status information update?
Airline websites and apps update every few minutes, usually between two and five minutes. Flight tracking sites like FlightAware update even more frequently because they pull data directly from radar. The airport's departure board updates in real time as gates and times change.
Can I see my flight status without a confirmation number?
Yes. Flight tracking websites let you search by flight number alone — you do not need a confirmation number. The airport's departure board also shows all flights by number. However, the airline's website and app usually require your confirmation number and last name to show your specific booking.
What if the airline website says on time but the tracking site shows the plane is delayed?
The tracking site is probably more accurate. Flight tracking data comes from the aircraft itself and radar, so it reflects what is actually happening. Airlines sometimes do not update their systems until a delay is officially confirmed, which can take 10 or 15 minutes. Trust the real-time location data over the airline's status if they disagree.
Do I need to pay for flight tracking apps?
No. FlightAware, FlightRadar24, Google Flights, and Hopper all offer free versions with real-time tracking and alerts. Some apps offer paid premium versions with extra features, but the free versions show you everything you need to know about delays and flight status.
Can I check a flight status if I am not the passenger?
Yes, if you have the flight number. Flight tracking websites and airport departure boards show all flights by number, so anyone can look up a flight. However, the airline's website will only show detailed booking information if you have the confirmation number and the passenger's last name.
