Where to check for cancelled flights

The airline's website and app are your fastest source. Log in to your account or enter your confirmation number on the carrier's homepage — most show cancellation status within minutes of a decision. The airline will also send an email or text to the address or phone number on your booking, though this can lag by an hour or more during widespread disruptions.

The FAA's website (faa.gov) lists system-wide delays and ground stops by airport, but does not show individual flight cancellations. FlightAware and FlightRadar24 track real aircraft in the air and show cancellations as they happen, but they pull data from the airlines themselves — so you are seeing the same information as the airline's app, just repackaged. Check your airline first, because that is where the official record lives.

If you booked through a travel agent or third-party site like Kayak or Expedia, log into that site as well. Some third-party sites update slower than the airline, so do not rely on them as your only source. The airline's own system is always the authoritative one.

Key Takeaways

  • Your airline's website or app will show cancellation status first, often before email or text notification reaches you.
  • Cancellations are usually announced 24 to 48 hours before departure, but can happen as late as the gate during severe weather or mechanical failure.
  • If your flight is cancelled, the airline must offer you a rebooking on the next available flight at no extra cost, or a refund of your ticket price.
  • Rebooking onto a competitor's flight is not required by law, though some airlines offer it as a courtesy during major disruptions.
  • You are may have access to to compensation under Department of Transportation rules only if the cancellation was within the airline's control — not for weather or air traffic delays.

Why flights get cancelled and when you will know

Weather is the most common reason — thunderstorms, snow, fog, or wind that exceeds the aircraft's operating limits. Mechanical problems are second: an engine issue, hydraulic leak, or avionics failure discovered during preflight. Crew unavailability (a pilot or flight attendant missing a connection) and air traffic control decisions (a ground stop issued by the FAA) account for most of the rest. A few cancellations happen because the airline oversold the flight and could not find enough volunteers to give up their seats.

The airline usually announces a cancellation 24 to 48 hours before the scheduled departure time, giving you time to rebook. During severe weather events affecting multiple flights, the airline may cancel in waves as conditions worsen. If a mechanical problem is found during boarding or preflight, you might learn about cancellation just hours before departure — or even at the gate. This is rare but happens.

The time of year matters. Winter months see more weather cancellations. Summer sees more mechanical issues because aircraft fly more hours per day. Holiday travel periods see more crew-related cancellations because the system runs at full capacity with no buffer.

What the airline must offer you

By Department of Transportation rule, if your flight is cancelled, the airline must offer you one of three things: a rebooking on the next available flight to your destination at no extra cost, a rebooking on a later flight if that suits you better, or a refund of your ticket price. You choose which one. If the airline books you on a later flight and you miss a connection because of the delay, the airline must rebook that connection too.

The rebooking must be on the same airline or a partner airline if the airline operates the route. If the airline does not operate your destination, it must book you on a competitor's flight — this is called an "involuntary reroute." You do not have to pay extra, and you do not have to accept a flight that arrives more than one hour later than your original booking (though the airline will ask you to accept it).

If you choose a refund, the airline must process it within seven business days. The refund covers your ticket price only — not hotel, meals, or other expenses you incur because of the cancellation. Some airlines offer travel vouchers instead of cash refunds; you can refuse the voucher and demand cash, though the airline may push back.

When you are may have access to to compensation money

The Department of Transportation requires airlines to pay compensation only when the cancellation was within the airline's control. A cancellation caused by weather, air traffic control decisions, or security threats does not trigger compensation. A cancellation caused by a mechanical problem, crew scheduling failure, or overselling does trigger compensation — usually $250 to $750 depending on how late you arrive at your destination.

The airline is not required to tell you that you are may have access to to compensation. You have to request it yourself, usually through the airline's website or by calling customer service. Keep your booking confirmation, boarding pass, and proof of the cancellation reason (the airline's email or website screenshot). If the airline denies your claim, you can file a complaint with the Department of Transportation or pursue the claim in small claims court.

Compensation is separate from a refund. You can receive both — a refund of your ticket price and compensation for the inconvenience. The compensation does not cover your hotel or meals; it is a fixed amount set by the government.

How to rebook yourself if the airline's system is overwhelmed

During a major disruption affecting hundreds of flights, the airline's phone lines and website can become unreachable for hours. If you cannot reach the airline through normal channels, you have options. Call the airline's customer service number listed on your ticket (not the general reservations line). If that fails, go to the airport and speak to an agent at the ticket counter — they can rebook you when ready and have access to real-time seat inventory.

Some airlines allow you to rebook online through their website or app even when phone lines are jammed. Log in, find your cancelled flight, and look for a "rebook" or "change flight" button. This often works faster than calling. If you booked through a travel agent, contact them — they can sometimes rebook you while the airline's own system is overloaded.

Do not book a new ticket on a different airline out of pocket and then ask the original airline for a refund. The airline will refund your original ticket, but you will be out the cost of the new ticket. Wait for the airline to rebook you first, or get a refund and then book a new ticket yourself.

What to do if you are stranded overnight

If the airline cannot rebook you on a flight departing the same day, you are may have access to to hotel accommodations and meals at the airline's expense. The airline must provide these directly — you do not pay and submit a receipt. Call the airline and ask for "irregular operations support" or "IOC support." The agent will arrange a hotel room and meal vouchers.

If the airline refuses to pay or the hotel is full, you can book a room yourself and submit the receipt to the airline for reimbursement. Keep all receipts. The airline will reimburse reasonable hotel and meal costs, usually up to $100 to $200 per night depending on the city. Alcohol is not covered.

If you decide to drive, take a train, or book a flight on another airline instead of waiting, the airline is not required to reimburse those costs. The airline's obligation is to rebook you on its own flights or a partner airline. If you choose a different mode of transportation, you are responsible for the cost.

Checking your status before you head to the airport

Check your airline's app or website the night before your flight and again two hours before departure. Most cancellations are announced by this point. If your flight shows "on time," it is very unlikely to be cancelled in the final two hours unless a mechanical problem is discovered during preflight or severe weather moves in unexpectedly.

Enable push notifications on your airline's app so you receive alerts the moment your flight status changes. This is faster than checking the website repeatedly. If you have a connection, check both flights — sometimes the first flight is on time but the second is cancelled, which means you will miss your connection.

If your flight is cancelled and you have already left for the airport, turn around and go home or to your hotel. Do not go to the airport and wait in line. Call the airline or use the app to rebook from wherever you are. The ticket counter will be overwhelmed during a cancellation event, and you will wait hours for an agent.

Frequently Asked Questions

Can the airline cancel my flight less than 24 hours before departure?

Yes. Weather, mechanical problems, and crew issues can force a cancellation at any time, including hours before departure or even at the gate. The airline is not required to give you advance notice. However, most cancellations happen 24 to 48 hours ahead because the airline tries to make decisions early so passengers can rebook.

Do I get money back if my flight is cancelled?

You get your ticket price refunded, or you can rebook on another flight at no extra cost. You do not automatically receive compensation money unless the cancellation was the airline's fault — not weather or air traffic control. You have to request compensation separately.

What if I booked a non-refundable ticket?

A cancellation overrides the non-refundable restriction. You can still choose a refund of your ticket price, or rebook on another flight. The "non-refundable" restriction applies only if you cancel the flight yourself, not if the airline cancels it.

Can I get compensation if the airline cancels my flight because of weather?

No. Weather is considered outside the airline's control, so compensation is not required. You are may have access to to a rebooking or refund, but not compensation money. The only exception is if the airline knew about the weather forecast and cancelled the flight anyway without trying to operate it — this is rare and hard to prove.

How long does it take to get a refund after cancellation?

The airline must process a refund within seven business days. In practice, refunds often take two to four weeks to appear in your bank account because the credit card company takes time to post the credit. If you do not see the refund after two weeks, contact the airline's customer service to confirm it was processed.
