How to check if your flight is cancelled

The fastest way to know if your flight is cancelled is to check your airline's website or app directly. Log in with your confirmation number or booking reference, and the system will show your flight status in real time. Most airlines update this information within hours of making a cancellation decision, though some do so the night before.

Your airline will also send you an email or text message if your flight is cancelled — but do not wait for that notification. Check yourself first, because you may need to rebook quickly if seats are limited. If you booked through a travel website like Kayak or Expedia rather than directly with the airline, log into that site instead; it pulls the same data from the airline's system.

The FAA's Flight Delay Information tool at faa.gov shows delays and cancellations at major U.S. airports, updated every 30 minutes. This is useful if you want to see whether cancellations are widespread at your departure or arrival airport, which tells you whether the problem is local or systemic.

The most common reasons flights get cancelled

Weather is the leading cause of cancellations in the United States. Heavy snow, ice, thunderstorms, and high winds can make runways unsafe or reduce visibility to the point where takeoff and landing are not possible. Winter months — December through February — see the highest cancellation rates because of snow and ice. Tropical storms and hurricanes also cause widespread cancellations along the Gulf Coast and Atlantic seaboard.

Staffing shortages have become more common since 2022. Airlines need pilots, flight attendants, and ground crew to operate a flight. If enough staff call in sick or do not show up, the airline may cancel rather than delay. This happens most often on weekends and holidays, when staffing is already thin.

Mechanical problems discovered during preflight checks can ground a plane. If the repair takes longer than a few hours, the airline cancels the flight rather than delay it further. Air traffic control delays — when the FAA restricts the number of planes that can take off or land — rarely cause outright cancellations but can trigger a cascade of cancellations if delays pile up.

When cancellations are most likely to happen

Winter travel carries the highest cancellation risk. If you are flying between December and February, especially to or from northern cities or mountain airports, check your flight status the day before you leave. Airports like Denver, Minneapolis, and Buffalo see cancellations in roughly 2 to 3 out of every 100 flights during winter months, compared to less than 1 out of 100 in summer.

Cancellations spike during severe weather events. If a hurricane is forecast to reach the coast within 48 hours, or if a blizzard warning is in effect for your departure or arrival city, assume your flight may be cancelled and check your airline's website daily. Some airlines begin cancelling flights 24 to 48 hours before the storm arrives.

Holiday travel periods — Thanksgiving week, Christmas week, and the week between Christmas and New Year — see higher cancellation rates because airports are busier and staffing is tighter. If you are flying during these windows, book an earlier flight if possible; cancellations are less common on the first day of a holiday rush than on the peak days.

What happens if your flight is cancelled

You have two rights under U.S. law: a refund of your ticket price, or a rebooking on the next available flight to your destination at no extra cost. You do not have to choose when ready. If the airline offers you a flight that leaves much later, you can ask for a refund instead and book with a different airline.

If the airline rebooks you on a later flight and you incur costs — a hotel night, a rental car extension, a meal — you can request reimbursement. Keep your receipts. Airlines are not required to reimburse you if the cancellation was caused by weather, but some do anyway if you ask. If the cancellation was caused by a mechanical problem or staffing issue, the airline's responsibility is clearer, and you have a stronger case for reimbursement.

If you booked a connecting flight with a different airline, and the cancellation causes you to miss it, contact the second airline when ready. They may rebook you on their next flight at no cost, or they may treat it as a missed flight and charge you a change fee. The outcome depends on whether the airlines have a code-share agreement and whether you booked the flights as one ticket or two separate tickets.

How far in advance airlines usually decide to cancel

Most cancellation decisions happen between 24 and 48 hours before the scheduled departure time. Airlines wait this long because they want to see whether weather will actually arrive, or whether a mechanical problem can be fixed in time. Waiting also gives them time to move planes and crews around to cover the flight with a different aircraft if possible.

In severe weather situations — a hurricane or blizzard with a clear forecast — airlines may cancel 48 to 72 hours in advance. This gives passengers time to rebook or request a refund before the airport becomes chaotic. Last-minute cancellations, made fewer than 6 hours before departure, usually mean a mechanical problem was discovered during preflight checks or a crew member did not show up.

Check your flight status the evening before you travel, and again the morning of your flight. If your flight is still scheduled but you see widespread cancellations at your airport, call your airline and ask whether they expect to cancel yours. Some airlines will let you rebook on an earlier flight for free if conditions look bad.

What to do if you think your flight might be cancelled

If severe weather is forecast for your travel date, check your airline's website and the FAA's Flight Delay Information tool daily. Do not wait until the day of your flight. If cancellations are already happening at your airport, call your airline and ask whether you can rebook on an earlier flight before the weather arrives. Many airlines allow free rebooking 24 hours before departure if weather is a factor.

Pack your carry-on bag the night before so you can leave quickly if you decide to take an earlier flight. If you are driving to the airport, leave extra time in case roads are icy or visibility is poor. If you are flying into a city where weather is expected, book a hotel with a cancellation policy that lets you cancel for free up to 24 hours before arrival.

If your flight is cancelled and you need to get to your destination urgently, check whether other airlines are still flying the same route. Sometimes one airline cancels while another continues, especially if they use different airports or have different weather minimums. A ticket on a competing airline may cost more, but it could be worth it if your trip is time-sensitive.

Frequently Asked Questions

Can an airline cancel my flight just because it is not full?

No. U.S. law does not allow airlines to cancel a flight straightforward because ticket sales are low. They can only cancel for operational reasons: weather, mechanical problems, staffing issues, or air traffic control restrictions. If you suspect an airline cancelled your flight for financial reasons, you can file a complaint with the Department of Transportation.

Do I get money back if my flight is cancelled?

Yes. You can choose either a refund of your ticket price or a rebooking on the next available flight at no extra cost. If the airline rebooks you on a flight that leaves much later, you can request a refund instead. Some airlines also reimburse hotel and meal costs if you ask, though they are not legally required to do so unless the cancellation was their fault.

What if I booked a non-refundable ticket?

A non-refundable ticket still entitles you to a refund if the airline cancels the flight. The "non-refundable" restriction only applies if you cancel yourself. If the airline cancels, you get your money back or a rebooking, regardless of the ticket type.

How do I know if my flight is cancelled versus delayed?

A delay means the flight will still depart, but later than scheduled. A cancellation means the flight will not operate at all. Check your airline's website or app; it will clearly state "cancelled" or show a new departure time. If you see a new time that is hours later than the original, call the airline to confirm whether it is a delay or a cancellation, because the system sometimes takes time to update.

Can I get a refund if the airline cancels my flight but offers me a flight the next day?

Yes. You can accept the rebooking, or you can request a refund instead. You do not have to take the airline's first offer. If the new flight does not work for your schedule, ask for a refund and book with a different airline or on a different date.
