Where to check flight cancellations right now

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 — cancelled, on time, or delayed. Most airlines update this information within two to four hours of a decision, though some cancellations are announced 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 proactively, especially if weather is severe in your departure or arrival city. The airline's website is always more current than email.

If you booked through a third-party site like Expedia, Kayak, or Google Flights, log into that site first — it usually pulls live data from the airline. However, go directly to the airline's own system if the third-party site shows conflicting information, because the airline's system is the source of truth.

Key Takeaways

  • Check your airline's website or app using your confirmation number to see your flight status before relying on email or text alerts.
  • Cancellations are usually announced the night before or early morning, but weather-related decisions can come within hours of departure.
  • If your flight is cancelled, the airline must rebook you on the next available flight at no extra cost or refund your ticket price in full.
  • Call your airline directly if the website is slow or unclear, because phone lines often have real-time information when the site is overwhelmed.
  • Check your airline's cancellation policy before tomorrow — some airlines waive change fees during weather events, while others do not.

What happens if your flight is actually cancelled

If your flight shows cancelled on the airline's system, you have two rights: the airline must rebook you on the next available flight to your destination at no extra charge, or they must refund the full ticket price. You do not have to choose when ready — you can call the airline and ask what flights are available before deciding.

The rebooking is usually automatic if you check the website within a few hours of the cancellation. The airline will assign you to the next flight with available seats. If that flight is days away and you cannot wait, call the airline and ask to be rebooked on a competitor's flight — some airlines will pay for this if their own schedule is too sparse.

Keep your confirmation number and any cancellation notice from the airline. You will need it to prove the cancellation if you later claim a refund or dispute a charge with your credit card company.

When cancellations are most likely to be announced

Weather-related cancellations usually come between 4 a.m. and 8 a.m. on the day of the flight, once the airline's operations team has assessed conditions at both airports. Mechanical or crew-related cancellations often come the night before, because those issues are known in advance. Cancellations due to low demand (rare for tomorrow's flights) are announced days ahead.

If your flight departs early morning, check the airline's website the night before around 10 p.m., then again at 5 a.m. If your flight departs afternoon or evening, the final decision often comes by mid-morning. Do not assume your flight is safe just because it has not been cancelled by 9 a.m. — some decisions come as late as two hours before departure, though this is uncommon.

What to do if the website is down or slow

During major weather events or widespread cancellations, the airline's website and app often become slow or crash from too many users checking at once. If you cannot load the page, call the airline's customer service line. Phone lines move slower than the website, but they have access to the same real-time data and can tell you your flight status in under five minutes.

Have your confirmation number ready before you call. If you are on hold for more than 20 minutes, hang up and try again in 15 minutes — call volume drops in waves. Early morning (before 6 a.m.) and late evening (after 9 p.m.) usually have shorter wait times than mid-morning.

How to prepare in case your flight is cancelled

Before tomorrow arrives, write down your airline's customer service phone number and your confirmation number in your phone or on paper. If your flight is cancelled and the website crashes, you will not be able to look these up easily.

Check your airline's policy on cancellations and rebooking. Some airlines automatically rebook you on the next flight with no action needed. Others require you to call or go online to accept the rebooking. A few airlines offer hotel vouchers or meal credits if the cancellation strands you overnight, but this is not required by law — it depends on the airline's own policy.

If you have a tight connection or a critical appointment at your destination, consider calling the airline tonight to ask about backup flights. If your flight is cancelled, you will want to know when ready whether the next available flight gets you there in time.

Checking for cancellations at your destination airport

Sometimes your flight is not cancelled, but the airport you are flying into has so many cancellations that your airline decides to cancel yours to avoid stranding you. Check the weather forecast for your destination city as well as your departure city. If a major storm is hitting your arrival airport tomorrow, there is a higher chance your flight will be cancelled even if your departure city is clear.

You can also check the FAA's website or your destination airport's website for notices about weather delays or ground stops. A ground stop means no planes are landing at that airport, and airlines will cancel flights heading there rather than have planes sit on the tarmac.

Frequently Asked Questions

Can I get a refund if my flight is cancelled?

Yes. If your flight is cancelled, you can request a refund of the full ticket price instead of accepting a rebooking. Contact your airline directly or log into your booking to request the refund. The airline must process it within a set timeframe, usually 7 to 10 business days, though some airlines take longer.

Do I get money if my flight is cancelled?

No. A cancellation is not the same as a delay. The airline owes you a rebooking or refund, but not cash compensation. Cash compensation (usually $200 to $600 depending on flight length) is only required if you are bumped from an oversold flight, not if the flight is cancelled.

Will my airline automatically rebook me if my flight is cancelled?

Most airlines automatically rebook you on the next available flight to your destination. Check your email and the airline's website to see what flight you have been assigned. If you do not like the new flight, call the airline and ask for other options.

What if I do not want to fly tomorrow and want to cancel myself?

Contact your airline and ask about their cancellation policy. If you cancel, you may receive a credit toward a future flight, a refund, or nothing, depending on the ticket type you bought and the airline's rules. Basic economy tickets often have no refund option, while higher fares usually do.

How do I know if my flight is cancelled if I am already at the airport?

Check the departure boards at the airport — they show cancellations in real time. You can also ask at your airline's ticket counter. If your flight is cancelled while you are at the airport, the airline will rebook you or refund you on the spot.
