Where to learn about your flight is delayed
The fastest way to check your flight status is the airline's website or app. Go to the carrier's homepage, find the "Flight Status" or "Track Your Flight" section, and enter your confirmation number or flight number. Most airlines show delays within minutes of a change, sometimes before passengers receive a text or email notification.
If you do not have your confirmation number, you can search by departure city, arrival city, and date instead. The airline will display whether the flight is on time, delayed, cancelled, or boarding. You will also see the reason for the delay — weather, mechanical issue, crew scheduling, or air traffic control — though the explanation may be brief.
The airline's app is often faster than the website because it sends push notifications the moment a delay is announced. If you are at the airport, ask an agent at the ticket counter or gate directly; they have access to real-time information that may not yet be public.
Key Takeaways
- Check your airline's website or app first by entering your confirmation number or flight number to see current status and delay length.
- Most airlines notify passengers by text or email only after posting the delay online, so checking the website is faster than waiting for a message.
- The reason for the delay — weather, mechanical, crew, or air traffic — is usually listed but may not explain the full cause.
- If you are already at the airport, ask a gate agent for the most current information, as delays can change minute by minute.
- Third-party flight tracking sites like FlightAware show delays but may lag a few minutes behind the airline's own system.
Using third-party flight tracking websites
Sites like FlightAware, FlightRadar24, and Google Flights pull delay information from airline systems, but they typically update a minute or two after the airline's own website. These sites are useful if you want to track a flight you are not booked on — for example, checking whether your connecting flight is on time — or if you want historical data about how often a particular route runs late.
FlightAware shows the gate, runway position, and estimated arrival time in real time. Google Flights displays delays alongside price history and seat maps. Neither site is faster than checking the airline directly, but both are free and do not require a login.
What to do if your flight is delayed
Once you confirm the delay, check the airline's policy on your ticket. Most carriers offer a rebooking on the next available flight at no charge if the delay is their responsibility — mechanical failure, crew scheduling, or maintenance. If the delay is due to weather or air traffic control, the airline is not required to rebook you, but many do as a courtesy.
If the delay is long enough that you will miss a connection, contact the airline when ready through the app, website, or phone. Do not wait until you land; agents can rebook you before you arrive. Have your confirmation number ready and know your destination so the agent can find the next available flight.
Keep receipts for any meals or hotels you buy while delayed. Some airlines reimburse expenses for delays over a certain length — usually four to six hours — but only if you ask and provide proof. The policy varies by airline and by whether the delay was within their control.
Delays caused by weather versus airline issues
Weather delays are treated differently from mechanical or crew delays. If your flight is delayed because of a thunderstorm, snow, or wind, the airline is not legally required to rebook you on another carrier or pay for meals and hotels. The delay is considered an "act of God" outside the airline's control.
If the delay is caused by a mechanical problem, crew shortage, or scheduling issue, the airline must rebook you on the next available flight at no charge. Some airlines also provide meal vouchers or hotel rooms for overnight delays caused by their own operations. Check your airline's website for its specific policy, or ask an agent at the gate.
In practice, many airlines offer the same help for both types of delays — rebooking and sometimes meals — even though they are not legally required to do so for weather. It is worth asking, especially if you have a tight connection or important appointment.
How long delays typically last
A delay under 30 minutes is usually resolved quickly — the airline is waiting for a crew member, a piece of equipment, or air traffic to clear. These delays often disappear without the flight being rebooked.
Delays of 30 minutes to two hours usually mean the airline is troubleshooting a mechanical issue, waiting for a connecting flight to arrive, or dealing with air traffic congestion. Most of these flights depart eventually, though some are cancelled if the problem cannot be fixed.
Delays over two hours are more likely to result in cancellation, especially if they are weather-related. If your flight has been delayed more than two hours and you see no updated departure time, ask an agent whether the flight is still scheduled to depart or if it will be cancelled. Do not assume — airlines sometimes hold a flight in delayed status for hours before officially cancelling it.
Checking delays before you go to the airport
Check your flight status the night before and again two hours before departure. Most delays are announced within 24 hours of the flight, but some appear only on the day of travel. If your flight is delayed by more than an hour, you have time to adjust your plans — leave for the airport later, reschedule a meeting, or arrange ground transportation differently.
Set up notifications in the airline's app so you receive alerts the moment the status changes. This is especially useful if you are not actively watching the flight. You can usually choose to be notified by push notification, text, or email.
If you are checking a flight for someone else — a family member or friend — ask them for their confirmation number. You can then track their flight without needing to log into their account on most airline websites.
What happens if your flight is cancelled instead of delayed
A cancellation is different from a delay. If your flight is cancelled, the airline must rebook you on the next available flight to your destination at no charge, even if the cancellation was due to weather. You can also request a refund of your ticket price instead of a rebooking.
Cancellations are usually announced at least a few hours before departure, though sometimes they happen with little notice. Check your flight status regularly on the day of travel, especially if weather is poor or there are widespread delays in your region.
If your flight is cancelled and you choose a refund, the airline will return the ticket price to your original payment method within a set timeframe — usually 7 to 10 business days. You will not receive a refund for baggage fees, seat upgrades, or other add-ons unless you specifically request them.
Frequently Asked Questions
How often do airlines update flight status?
Airlines update status in real time as changes occur. A delay may be posted within minutes of being announced to the crew, or it may take 15 to 30 minutes to appear on the website. Checking every 30 minutes on the day of travel is usually enough; checking more frequently will not give you information faster than the airline has it.
Can I get a refund if my flight is delayed but not cancelled?
No. A delay alone does not may have access to you to a refund under U.S. law. You can only request a refund if the flight is cancelled or if you choose not to take a rebooking. Some airlines offer travel credits or vouchers for long delays as a courtesy, but this is not required.
What if the airline's website shows a different delay time than the app?
The app and website pull from the same system, but the app may update slightly faster because it sends notifications. If you see different times, the app version is usually more current. Refresh the website or close and reopen the app to sync the latest information.
Do I have to go to the airport if my flight is delayed?
No. If your flight is delayed by several hours, you can wait at home and check the status periodically. However, if the delay is under an hour or the airline has not given a new departure time, it is safer to head to the airport on schedule. Delays can clear suddenly, and you do not want to miss your flight.
Will the airline text me about a delay?
Most airlines send text or email notifications for delays, but the notification may come after you have already checked the website. Signing up for push notifications in the airline's app is faster because the app alerts you the moment the status changes, before the airline sends a mass text to all passengers.
