How to learn about your flight is cancelled before Sunday
Your airline will post a cancellation on their website and app, usually 24 hours before departure but sometimes earlier if weather or staffing problems are known. The fastest way to check is to log into your airline's app or website, enter your confirmation number, and look at your flight status. If it shows "cancelled", you will see rebooking options right there. Do not wait for an email — the airline sends those after you check the app.
If your flight is not yet showing as cancelled but you are worried about Sunday weather or other disruptions in your area, call your airline's customer service line or use their chat feature to ask whether cancellations are expected. They can tell you if the route is already experiencing delays or if weather forecasts are affecting scheduling. Some airlines also let you change your flight to an earlier day at no extra cost if conditions look bad, even before an official cancellation.
Check the FAA website (faa.gov) under "Airport Status" to see if your departure or arrival airport is reporting delays or closures. This shows real-time conditions and helps you understand whether the problem is local to your airport or system-wide. If your airport is closed or severely delayed, cancellations are more likely.
Key Takeaways
- Check your airline's app or website using your confirmation number — this is where cancellations appear first, usually 24 hours before departure.
- The FAA's Airport Status page shows real-time delays and closures at your departure and arrival airports.
- Call your airline's customer service to ask whether cancellations are expected on your route, especially if Sunday weather looks severe.
- Many airlines let you move to an earlier flight at no cost if you contact them before an official cancellation, even if your original flight is still listed as on-time.
- If your flight is cancelled, your airline must offer you a rebooking on the next available flight or a refund of your ticket price.
What happens if your flight is cancelled
Once a cancellation is posted, your airline is required by the Department of Transportation to offer you either a rebooking on the next available flight to your destination (even on a different airline if needed) or a refund of your full ticket price. You choose which option you want. The rebooking does not have to be on Sunday — it could be Monday or later, depending on availability.
If you choose the refund, the airline must process it within seven business days. If you choose rebooking, the airline will assign you to the next flight with an open seat. You can usually change this assignment through the app or by calling customer service if another flight works better for you.
Reasons flights get cancelled on Sundays
Sunday cancellations happen most often because of weather — thunderstorms, snow, fog, or high winds can close runways or make takeoff unsafe. Check the National Weather Service forecast for your departure and arrival cities on Sunday morning to see if severe weather is expected.
Staffing shortages and mechanical issues also cause cancellations, though these are usually announced 24 to 48 hours ahead once the airline knows a plane will not be ready or crew will not be available. Fuel shortages and air traffic control delays are less common but can affect specific routes.
How to prepare if cancellation seems likely
If weather forecasts show storms or severe conditions for Sunday, pack your carry-on the night before so you can move to a different flight quickly if your airline offers one. Have your confirmation number and ID ready. read your airline's app so you can see status updates and rebooking options without relying on phone lines, which get busy after a cancellation.
If you have a connecting flight on Sunday, ask your airline whether they will rebook you on a later flight that same day or the next day if your first flight is cancelled. Some airlines will automatically do this; others require you to ask. Getting this in writing (via email or chat) protects you if the airline later claims you did not have a connection.
What to do if you need to travel Sunday no matter what
If your Sunday trip is essential and cancellation risk is high, consider booking a flight on Saturday instead, or book two separate tickets on different airlines for Sunday so you have a backup. This costs more but removes the risk of being stranded. Some airlines also let you purchase a "flexible ticket" that lets you change your date and time without a fee, though this usually costs extra at purchase.
If you have already booked Sunday and conditions look bad, contact your airline as soon as possible — even a day or two before — to ask about moving to Saturday or Monday. Many airlines will move you at no cost if you call before the flight is cancelled, rather than waiting for the cancellation and then fighting for a rebooking.
Tracking your flight status in real time
Set up notifications on your airline's app so you get an alert the moment your flight status changes. Most apps let you turn on push notifications for delays and cancellations. You can also check FlightAware.com or FlightRadar24.com, which show live flight tracking and often display cancellations before the airline's own website updates.
On Sunday morning, check your flight status every hour starting at 6 a.m., even if your flight is not until afternoon. Cancellations sometimes get posted in waves as the airline assesses the day's conditions. The earlier you know, the more rebooking options will be available.
Frequently Asked Questions
Do airlines have to tell me 24 hours before if my flight is cancelled?
No. Airlines must post cancellations as soon as they know, which can be anywhere from a few hours to 24 hours before departure. Weather-related cancellations sometimes happen with less notice because conditions change. Check your airline's app frequently rather than waiting for a notification.
Can I get a hotel or meal voucher if my Sunday flight is cancelled?
The Department of Transportation does not require airlines to pay for hotels or meals after a cancellation. Some airlines offer them as a courtesy, but it depends on the airline and the reason for the cancellation. Ask your airline's customer service what they will cover. You can also check your travel insurance or credit card benefits — some cover these costs.
What if the airline cancels my flight but I already paid for a hotel or rental car?
The airline is not responsible for those costs. You would need to contact the hotel or rental company to change your reservation. This is why travel insurance that covers cancellations can be useful — it reimburses you for prepaid costs if your flight is cancelled.
Can I get compensation money if my flight is cancelled?
The U.S. Department of Transportation does not require airlines to pay compensation for cancellations. You are may have access to to a rebooking or refund, but not cash. Some countries (like those in the EU) do require compensation, but that only applies if you are flying from those countries.
Should I call the airline or use the app to rebook after a cancellation?
Use the app first — it is faster and shows all available flights when ready. Phone lines get extremely busy after a cancellation. If the app does not show a flight that works for you, then call customer service to ask about options on other airlines or later dates.
