Flights usually continue during a delay, but not always to the same gate or time
When an airport announces a flight delay, the flight itself has not been cancelled — it is still scheduled to depart, just later than originally posted. However, the delay may be long enough that you miss a connection, or severe enough that the airline decides to cancel the flight altogether and rebook you on another one. The fastest way to know whether your specific flight is still running is to check your airline's website or app using your confirmation number, or to call the airline directly. Do not rely on the airport's general delay announcements; they tell you the airport is experiencing delays, not whether your individual flight will leave.
A delay does not mean your flight will not run. It means the departure time has moved later. Some flights continue to operate normally while others around them are held or cancelled, depending on the cause of the delay and which airlines are affected. Your airline's system knows your specific flight status and can tell you whether you are still booked on it or whether it has been cancelled and you have been rebooked.
Key Takeaways
- A flight delay means the departure time has moved later, not that the flight has been cancelled or will not run.
- Check your airline's website, mobile app, or customer service line using your booking confirmation number to see your specific flight status.
- If your flight is cancelled, the airline will automatically rebook you on the next available flight at no extra charge.
- If you have a connecting flight, call your airline to confirm whether you will make the connection or need to be rebooked before you leave for the airport.
- Airport delays caused by weather, air traffic, or mechanical issues do not always affect every flight equally — some airlines and routes may be moving while others are held.
Where to check your flight status in real time
Your airline's website and mobile app are the most current sources. Log in with your confirmation number (also called a booking reference or PNR), and you will see the current departure time, gate assignment if it has been posted, and whether the flight is on time, delayed, or cancelled. Most airlines update this information every 15 to 30 minutes during disruptions.
If you do not have the app, call the airline's customer service number — it is on your booking confirmation email and on the airline's website. Have your confirmation number ready. A representative can tell you the current status, whether you are still booked on that flight, and what your options are if the flight has been cancelled or if you will miss a connection.
Flight tracking websites like FlightAware and FlightRadar24 show real-time aircraft movement and can tell you whether a plane assigned to your flight is currently in the air or on the ground. However, these sites do not show airline rebooking policies or whether seats are available on other flights, so use them to understand the situation but contact your airline to make changes.
What happens if your flight is cancelled
If your flight is cancelled, the airline is required by law to rebook you on the next flight to your destination at no extra charge. You do not have to do anything — the airline will automatically place you on another flight, usually the next one with available seats. You will receive a notification by email or text with your new flight details.
If the next available flight is the following day or later, you may be may have access to to a hotel room and meals, depending on the airline's policy and the reason for the cancellation. Weather and air traffic control delays are usually not the airline's responsibility, so they may not provide hotel coverage in those cases. Mechanical failures and crew issues are the airline's responsibility, and most will cover lodging. Ask the airline what they will cover before you book a hotel yourself.
If the rebooked flight does not work for you, you can request a refund instead of rebooking. The airline must offer a refund if the new flight arrives more than three hours after your original arrival time, though some airlines will refund sooner. You can also ask to be rebooked on a competing airline if your airline has no other flights to your destination that day.
If you have a connecting flight
A delay at your first airport does not automatically cancel your connection. However, if the delay is long enough that you will miss your connection, you need to contact your airline before you board the first flight. Tell them you will not make the connection and ask to be rebooked on a later flight to your final destination.
If you do not notify the airline and you miss the connection, the airline may cancel the rest of your itinerary, including your return flight. Some airlines will rebook you on the next available flight if you miss a connection due to their delay, but others will not. Calling ahead protects you either way. If your first flight is operated by one airline and your connection is with a different airline, the airlines do not automatically coordinate rebooking — you will need to contact both airlines or work with a travel agent.
How long delays typically last
Delays caused by air traffic control congestion or minor mechanical issues often last 30 minutes to two hours. The airline will usually post an estimated new departure time within 15 to 30 minutes of the delay announcement. Weather delays can last much longer — a thunderstorm might ground flights for three to six hours, and winter weather can cause delays of a full day or more.
If a delay reaches three hours or more, the airline is required to offer you the choice to wait for the flight or receive a refund. You do not have to accept a rebooking on a flight days later if you want your money back instead. Ask a gate agent or call the airline to request a refund if the delay is that long and you decide not to wait.
What to do while you wait
Stay near your gate or in the airport, even if the delay is long. Airlines can change gate assignments without notice, and if you are not there when boarding begins, you may be left behind. Check the airport's flight information display screens and your airline app every 30 minutes for gate changes and updated departure times.
If the airline has not posted a new departure time within an hour, ask a gate agent for an estimate. They may have information about the cause of the delay and how long it is expected to last. If the delay is weather-related, the agent can usually tell you whether the weather is expected to clear or worsen. Bring a charger or power bank for your phone, because you will need it to check your flight status and contact the airline if plans change.
Frequently Asked Questions
Can I leave the airport if my flight is delayed?
You can leave if the delay is expected to last several hours and you have time to return before boarding. However, airlines can change departure times without notice, so you risk missing your flight. If you do leave, set a phone alarm for 90 minutes before the estimated departure time and head back to the airport when ready.
Will I get a refund if my flight is delayed?
A delay alone does not may have access to you to a refund. You can request a refund only if the delay causes you to arrive more than three hours late at your destination, or if the airline cancels the flight. Some airlines offer travel credits or vouchers for long delays, but these are voluntary — check your airline's policy.
What if the airline oversells my rebooked flight?
If you are rebooked on a flight that is overbooked, the airline must honor your seat because you were involuntarily rebooked due to their cancellation or delay. You cannot be bumped from a flight you were rebooked onto.
Do I need to pay extra to change my flight if it is delayed?
No. If your flight is cancelled or delayed so long that you miss a connection, the airline must rebook you at no extra charge. If you choose to change to a different flight on your own before the airline cancels yours, you may be charged a change fee depending on your ticket type and the airline's policy.
How do I know if my flight is delayed because of weather or the airline's fault?
The airline will tell you the reason when you check your flight status or call customer service. Weather and air traffic control delays are not the airline's responsibility, so they usually do not provide hotel or meal coverage. Mechanical failures, crew issues, and overbooking are the airline's responsibility, and they will cover expenses.
