Check your flight status on the airline's website or app

The fastest way to see if your flight is on time is to go directly to your airline's website or mobile app. You'll need your confirmation number (the six-character code from your booking email) and either your last name or ticket number. Enter those details into the "Flight Status" or "Manage My Booking" section, and the system will show you the current status: on time, delayed, cancelled, or boarding.

Most airlines update this information every 15 to 30 minutes once your flight enters the system, which is usually 24 hours before departure. If you're checking more than a day ahead, the status may show "scheduled" rather than a real-time update. The airline app often sends push notifications when your flight status changes, so turning those on means you won't have to keep checking manually.

If you've already checked in online, you can usually see your flight status without logging in again—just search by flight number and date. This works whether you booked directly with the airline or through a third-party site like Kayak or Expedia.

Key Takeaways

  • Your airline's website or app is the official source and updates every 15 to 30 minutes once your flight is in the system.
  • You need your confirmation number and last name to look up your specific flight, or you can search by flight number and date.
  • Third-party flight tracking sites like FlightAware and FlightRadar24 show real-time radar data and can sometimes catch delays before the airline updates its website.
  • Airport websites display departure and arrival boards that update in real time, useful if you're already at the terminal.
  • Turning on push notifications from your airline app means you'll be alerted to status changes without checking repeatedly.

Use real-time flight tracking sites for live radar data

If your airline's website hasn't updated yet or you want to see where the plane actually is, FlightAware and FlightRadar24 show live radar positions and can sometimes detect delays before the airline announces them. Both sites let you search by flight number (for example, "United 447") or by aircraft registration. They display the plane's current altitude, speed, and position on a map, plus historical data about how often that specific flight is delayed.

FlightAware is free and shows basic radar tracking. FlightRadar24 has a free version with a slight delay in radar updates (about 5 to 10 seconds behind live) and a paid subscription for real-time data. Neither site replaces your airline's official status, but both are useful if you're trying to understand why a delay happened or if a plane is running late from a previous flight.

These sites are especially helpful if your flight is delayed because the aircraft is coming from another city. You can watch it approach your airport in real time and get a sense of when it will actually land.

Check the airport's departure and arrival board

If you're already at the airport or planning to head there soon, the departure and arrival boards in the terminal show real-time status updates. These boards are updated by the airport's operations center and often reflect changes faster than airline websites, especially for ground delays or gate changes. You can also find these boards online on most major airport websites—search for "[Airport Name] departures" or "[Airport Name] arrivals."

The airport board will show your flight number, scheduled departure time, current status, and gate number (once it's assigned, usually 1 to 2 hours before departure). If your flight shows "delayed," the board usually displays the new estimated departure time. If it shows "on time," that's the airline's current expectation, though it can still change.

Call your airline directly for confirmation

If you need to speak to a human or if the website is down, call your airline's customer service line. The number is on your booking confirmation email and on the airline's website. Have your confirmation number ready. The representative can tell you the current status, reason for any delay, and what to expect next.

Calling is also the right move if you're trying to decide whether to head to the airport. If your flight is delayed by several hours, the airline may rebook you on a different flight or offer a refund, depending on the reason for the delay and your airline's policy. A representative can explain your options before you leave home.

Understand what "on time" actually means

Airlines define "on time" as pushing back from the gate by the scheduled departure time, not landing at your destination by the scheduled arrival time. This means a flight can be marked "on time" even if it sits on the tarmac for an hour after pushing back. The scheduled arrival time on your ticket is an estimate based on typical flight time and winds, not a may provide.

If you see "on time" on your airline's website but the flight is still sitting at the gate, that's normal—the status updates once the plane actually leaves the gate. If your flight is scheduled to depart at 2 p.m. and it's now 2:15 p.m. and the status still says "on time," check again in a few minutes or call the airline, because the system may not have updated yet.

Set up alerts so you don't have to keep checking

Most airline apps let you turn on notifications for your specific flight. Once you've entered your confirmation number, look for a "Notify me" or "Alert" button and choose what you want to be notified about: status changes, gate assignments, or boarding time. You'll get a push notification on your phone when something changes, so you don't have to open the app repeatedly.

FlightAware also offers email and text alerts if you create a free account and add your flight. You can set it to notify you only if there's a delay of a certain length, so you won't get pinged for every small change. This is especially useful if you're checking a flight for someone else or if you're traveling with family and want one person to monitor the status.

What to do if your flight is delayed

Once you know your flight is delayed, the next step depends on how long the delay is. If it's less than an hour, you usually don't need to do anything—just plan to arrive at the airport a bit later. If it's more than an hour or two, contact your airline to ask about rebooking options, meal vouchers, or hotel accommodations if the delay is overnight.

If your flight is cancelled, your airline is required to rebook you on the next available flight to your destination at no extra charge, or offer a refund. You can also check if you're may have access to to compensation under U.S. Department of Transportation rules, which vary depending on the reason for the cancellation and how long the delay is. Your airline's website or a call to customer service can explain what you're may have access to to.

Frequently Asked Questions

How often do airline websites update flight status?

Most airlines update their websites and apps every 15 to 30 minutes once your flight is in the system, which is usually 24 hours before departure. Real-time flight tracking sites like FlightAware update more frequently based on radar data. If you're checking more than a day ahead, the status may just say "scheduled" rather than showing a real-time update.

Can I see my flight status without my confirmation number?

Yes. Most airlines let you search by flight number and date without a confirmation number. You can also search by aircraft registration on FlightAware and FlightRadar24. However, to see seat assignments, baggage info, or make changes, you'll need your confirmation number or ticket number.

Why does my airline say my flight is on time but I see it's delayed on FlightAware?

FlightAware shows real-time radar data, which updates faster than airline websites. If the plane is running late from a previous flight, FlightAware will show that before your airline updates its website. Check your airline's website again in 15 to 30 minutes—it should catch up. The airline's official status is what matters for rebooking and compensation.

What should I do if my flight is cancelled?

Call your airline when ready or use their website to rebook on the next available flight at no extra charge. You can also request a refund. If the cancellation was the airline's fault (not weather or a security issue), you may be may have access to to compensation under Department of Transportation rules. Ask your airline what you're may have access to to based on the reason for the cancellation.

Is there a way to know if a flight will be delayed before it's officially announced?

FlightAware and FlightRadar24 can sometimes show delays before airlines announce them, especially if the plane is running late from a previous flight or if there are weather delays. Checking these sites 2 to 3 hours before your departure can give you an early warning, but the airline's official status is the most reliable source.
