How to learn about your flight is delayed today

The fastest way to check your specific flight is to go directly to your airline's website or app and enter your confirmation number and last name. Most airlines show delays, gate changes, and cancellations in real time on their flight status page. You do not need to call — the website updates every few minutes and will tell you exactly what is happening with your flight.

If you do not have your confirmation number, you can search by flight number and date instead. Major airlines including Delta, United, American, Southwest, and JetBlue all have this search built into their homepage. The airport's website also posts real-time delays for all flights departing and arriving there — search for your airport code plus "flight status" to find that page.

The FlightAware website and app track flights across all airlines and show delays, cancellations, and gate information without requiring a booking confirmation. You can search by flight number, route, or airline. This is useful if you are picking someone up and need to know when they will actually land.

Why delays happen and what causes them right now

Flight delays fall into a few main categories: weather, air traffic control delays, mechanical issues, crew scheduling, and airport congestion. Weather is the most common reason — thunderstorms, snow, fog, and wind can ground flights or slow down takeoffs and landings. These delays are not the airline's fault and typically cannot be predicted more than a few hours in advance.

Air traffic control delays happen when airports are too busy to handle all the planes trying to land or take off at once. This is common on Friday afternoons, Sunday evenings, and around holidays. Mechanical delays occur when an aircraft needs repair before it can fly safely — these are usually short, but occasionally a plane has to be swapped out, which takes longer.

Crew scheduling delays happen when a flight crew is delayed on an earlier flight, which pushes back the next flight they are supposed to work. This creates a ripple effect through the day. Airport congestion — too many planes at gates, too few ground crew, or baggage system slowdowns — can also add 15 to 30 minutes to departure times.

What to expect if your flight is delayed

If your flight is delayed by less than an hour, the airline will usually hold the plane at the gate and push back when ready. You will see the new departure time on the airline's website and receive a text or email notification if you opted in during booking. Sit tight — the flight will leave as soon as the delay reason clears.

For delays longer than an hour, airlines are required by federal law to provide a written statement explaining the reason. Some airlines also offer meal vouchers, hotel rooms (if the delay is overnight), or rebooking on another flight. The rules differ by airline and by how long the delay is, so check your airline's website for their specific policy.

If your flight is cancelled, the airline must rebook you on the next available flight to your destination at no extra charge, or refund your ticket. You can also ask to be booked on a competitor's flight if the airline's next flight is more than a few hours away. Keep your boarding pass and any receipts for meals or hotels — you may be able to claim reimbursement.

How to prepare before you head to the airport

Check your flight status the night before and again the morning of your flight. Most delays are announced 24 hours ahead, though weather delays can pop up closer to departure. If you see a delay already posted, you know what to expect and can plan accordingly.

Arrive at the airport at the time your airline recommends, not based on your original departure time. If your flight is delayed, arriving early does not help — you will just wait longer. If it is cancelled, you want to be there to rebook in person, but that usually happens after the cancellation is announced.

Sign up for text or email alerts from your airline during booking. This way you will know about delays, gate changes, and cancellations without having to check the website constantly. Most airlines send these notifications automatically once you have a confirmed booking.

What happens if you miss a connection because of a delay

If your first flight is delayed and you miss your connection, the airline is responsible for getting you to your final destination. Tell a gate agent or call the airline as soon as you realize you will miss the connection — do not wait until you land. The airline will rebook you on the next available flight at no charge.

If the delay was the airline's fault (mechanical issue, crew scheduling, or their own operational problem), you may also be may have access to to compensation under Department of Transportation rules. The amount depends on how late you arrive at your final destination and whether the flight was domestic or international. Keep your boarding passes and any documentation of the delay.

If the delay was due to weather or air traffic control, the airline is not required to pay compensation, but they still must rebook you. Some airlines offer travel credits or vouchers as a courtesy even when they are not legally required to.

Tools and websites to track delays in real time

FlightAware.com and the FlightAware app show live flight tracking, delays, and cancellations for all airlines. You can search by flight number, route, or airport. The app also lets you set up notifications for specific flights.

Your airline's website or app is always the most accurate source for your specific booking. It shows your seat assignment, baggage allowance, and any changes to your flight. read the app before you travel so you have it on your phone at the airport.

Airport websites post real-time departure and arrival information for all flights. Search for your airport code plus "departures" or "arrivals" to find the live board. This is useful if you are picking someone up and want to know when they will actually land.

The FAA website (faa.gov) posts airport delay information and ground stops. If a major airport is experiencing delays, it will be listed there with the reason and expected duration. This is more technical but useful if you want to understand why delays are happening nationwide.

Frequently Asked Questions

Can I get my money back if my flight is delayed?

Delays alone do not may have access to you to a refund — you get a refund only if the flight is cancelled and you choose not to rebook. If your flight is delayed, the airline must get you to your destination, even if it takes hours longer. However, if the delay was caused by the airline's own mistake (not weather or air traffic control), you may be may have access to to compensation under Department of Transportation rules.

How long can an airline delay a flight before they have to cancel it?

There is no set time limit. An airline can delay a flight indefinitely as long as they are working to resolve the problem. However, if a flight is delayed more than three hours on the tarmac without taking off, federal rules require the airline to let passengers off the plane. If the delay is due to weather, the airline can keep you on the plane longer.

What should I do if I arrive at the airport and my flight is already delayed?

Check the airline's website or ask at the gate for the updated departure time. If the delay is short (under an hour), stay in the airport. If it is longer, ask the gate agent whether the airline is offering meal vouchers or hotel rooms. Keep any receipts — you may be able to claim reimbursement depending on the reason for the delay.

Do I have to pay extra to rebook on a different flight if mine is delayed or cancelled?

No. If your flight is cancelled or delayed so long that you miss a connection, the airline must rebook you on the next available flight to your destination at no extra charge. You can also ask to be booked on a competitor's flight if the airline's next option is significantly later.

How do I know if my delay is the airline's fault or due to weather?

The airline will tell you the reason when they announce the delay. Weather delays, air traffic control delays, and mechanical issues are all listed separately. If it says "weather," the airline is not required to pay compensation. If it says "mechanical" or "crew scheduling," that is usually the airline's responsibility, and you may be may have access to to compensation if you arrive more than three hours late.
