Check your airline's website or app first

The fastest way to learn about your flight is delayed is to go directly to your airline's website or mobile app and enter your confirmation number and last name. Most airlines show real-time status updates there—departure time, gate number, and any delays—before they post to other sites. This is where the airline posts changes first, so you see the information as soon as it's official.

If you booked through a third-party site like Kayak, Expedia, or Google Flights, those sites pull data from the airline but may lag by a few minutes. Going straight to the airline cuts out the middleman. You can also text your airline's flight status number if you have it in your confirmation email, though the website or app is usually faster.

Key Takeaways

  • Your airline's website or app shows delay information before any other source, updated in real time as the situation changes.
  • Flight tracking sites like FlightAware and FlightRadar24 show you the aircraft's actual location and can predict delays based on its movement.
  • Call your airline directly if the website is down or you need to know whether a delay affects your connection or refund may be able to access.
  • Airports post delay information on their own websites and departure boards, though this updates less frequently than airline systems.
  • Sign up for text or email alerts from your airline so you don't have to keep checking—notifications come automatically when status changes.

Use flight tracking websites for real-time aircraft location

FlightAware and FlightRadar24 show you where your aircraft actually is right now. Enter your flight number (the two-letter airline code plus the number, like AA123), and you'll see a map with the plane's current position, altitude, and speed. These sites pull data from radar and aircraft transponders, so the information is live and independent of what the airline is saying.

Flight tracking sites are useful because they can show you a delay before the airline officially announces one. If your flight was supposed to depart at 2 p.m. but the aircraft is still on the ground at 2:15 p.m., you know something is wrong. These sites also show you the aircraft's history—whether it's been delayed on previous flights that day, which can hint at whether the delay will be long or short.

Call the airline directly if you need when ready answers

If the website is slow, down, or you need to know something specific—like whether you'll make a connection or whether you're may have access to to a meal voucher—call your airline's customer service line. The number is on your confirmation email and on the airline's website. Have your confirmation number ready.

Phone lines are often busy during widespread delays, so expect a wait. If you're calling about a connection, ask the agent whether they can rebook you on the next flight to your final destination before you hang up. If you're asking about compensation or a refund, ask what the airline's policy is for delays of your length—this varies by airline and by how long the delay is.

Check the airport's website or departure board

Your departure airport posts delay information on its own website and on the physical departure boards in the terminal. Search "[airport name] departures" to find the airport's website, then look for the departures section. You'll see your flight listed with its current status.

Airport websites update less frequently than airline systems—sometimes every 5 to 10 minutes instead of in real time—so they're useful as a backup but not as your primary source. If you're already at the airport, the physical departure board is the official source for gate assignments and final departure times.

Sign up for alerts so you don't have to keep checking

Most airlines let you sign up for text message or email notifications about your flight. Go to your airline's website, find the "manage my booking" or "flight status" section, and enter your phone number or email. You'll get an automatic alert when your flight status changes—whether it's a delay, gate change, or cancellation.

This is the least stressful option because you don't have to remember to check. The alert comes to you. If you booked through a third-party site, that site may also offer alerts, though the airline's own alerts are usually faster and more reliable.

Understand what the delay status actually means

Airlines use specific language on their websites. "On time" means the flight is expected to depart at the scheduled time. "Delayed" means it will depart later than scheduled, and the site will show you the new departure time. "Cancelled" means the flight is not running at all, and you'll need to contact the airline about rebooking or a refund.

"Boarding" means passengers are currently getting on the plane. "Departed" means the plane has left the gate. If your flight shows "departed" but you haven't boarded yet, contact the airline when ready—you may have been left behind or the flight may have been reassigned to a different gate.

What to do if your flight is delayed

If your delay is more than a couple of hours, contact your airline to ask about meal vouchers, hotel accommodations, or rebooking on an earlier flight if one is available. Some airlines provide these automatically; others only if you ask. Have your confirmation number ready.

If you're connecting to another flight, call the airline right away. They can rebook you on the next available flight to your final destination, and they may waive change fees if the delay is their responsibility. If you're checking bags, ask whether they'll be automatically transferred to your new flight or whether you need to collect and recheck them.

Frequently Asked Questions

How often does flight status update on the airline website?

Most airlines update their website in real time or every few minutes. FlightAware and FlightRadar24 update every few seconds based on radar data. Airport websites may update every 5 to 10 minutes. If you're watching for a change, the airline app is fastest.

Can I get a refund if my flight is delayed?

Refund policies vary by airline and by how long the delay is. Most U.S. airlines do not offer refunds for delays—only rebooking on the next available flight. International flights and flights operated by European airlines have different rules. Call your airline to ask what they will offer for your specific delay.

What if the airline website says my flight is on time but I see it's still on the ground?

The airline website may not have updated yet. Wait a few minutes and refresh. If it still shows on time after 15 minutes and the plane is clearly not moving, call the airline. There may be a technical issue with the website, or the delay may not be official yet.

Do I need to be at the airport if my flight is delayed?

No. If your flight is delayed, you don't need to be at the airport until about two hours before the new departure time (one hour for domestic flights under two hours). The airline will tell you the new departure time on their website. If the delay is very long, some airlines will let you leave the airport and come back later—ask at the gate or call customer service.

Will my luggage be delayed if my flight is delayed?

Usually no. If you're checking bags and your flight is delayed on the ground, your bags will stay with the plane and depart with you. If you're connecting and your flight is delayed, ask the airline whether your bags will make the connection or whether you'll need to collect them at your connection airport.
