How to know if my flight is delayed or canceled (2026)
Quick Answer
The quickest way to know if your flight is delayed or cancelled is to check the airline’s own app, website or text/email alerts using your booking reference. Then confirm the status on the airport’s departures board or website, especially on the day of travel. If the airline and airport information do not match, treat the airline as the main source for your booking and contact it directly.
Overview
Flight status can change quickly, so the most reliable approach is to check more than one official source and keep checking as departure time gets closer. Start with the airline because it controls your booking, rebooking options and direct notifications. Then cross-check with the departure airport, which may post operational updates and gate information that appears before or after third-party apps refresh. If you are already travelling, look at airport screens as well as your phone, because gate changes and boarding calls can happen alongside a delay. To make this easy, have your booking reference or e-ticket number ready, and make sure the airline has your current mobile number and email address. Sign up for alerts as soon as you book, not when a disruption has already started. If your flight is cancelled or significantly delayed, keep all written updates and receipts, because you may need them for rebooking, refunds, care expenses or a compensation claim where the rules apply. Avoid relying only on general flight-tracking apps or social media posts; they are useful for context, but the airline and airport are the sources that matter most for real-time decisions.
Who this is for
Air passengers checking a flight before leaving for the airport, while travelling to the airport, or after arriving at the airport.
What you’ll need
- Airline name and flight number, or your booking reference
- A phone with internet access
- Access to your email and text messages
- The airline’s app or website
- The departure airport’s website or departures board
- Travel documents in case the airline asks to verify your booking
Before you start
Check that your booking contact details are correct in the airline account or booking record. If you booked through a travel agent or online travel company, note both the airline booking reference and the agent reference, because disruption messages may come from either.
Step-by-step
- 1
Check the airline’s official flight status first
Open the airline’s app or website and look up your flight using the flight number or booking reference. Read the current status carefully and check for messages about delay, cancellation, schedule change, gate change or rebooking options.
Why: The airline is the main authority for your booking and is usually the first place you will see whether the flight is still operating and what your options are.
- 2
Turn on alerts and check your contact details
Enable app notifications and confirm your mobile number and email address are correct in the booking. Check your spam or junk folder if you are expecting an email update.
Why: Delays and cancellations can happen after your first check. Alerts reduce the chance of missing a last-minute change.
- 3
Cross-check with the departure airport
Visit the airport’s official website departures page or check the airport screens if you are already there. Look for your flight number, departure time, gate and any operational note.
Why: Airport systems often show gate, terminal and local operational changes that affect when and where you need to be, even if the airline message is brief.
- 4
Check again close to departure
Recheck the status before leaving home, again on the way if possible, and again after you arrive at the airport. If bag drop or security queues are involved, still aim to arrive in line with the airline’s normal advice unless the airline tells you otherwise.
Why: Flight status is dynamic. A short delay can return to schedule, grow longer, or turn into a cancellation.
- 5
If the flight is cancelled or heavily delayed, use the airline’s self-service options immediately
Open the airline app or website and look for rebooking, refund or voucher options. If self-service is unavailable, join the airline’s official chat, phone queue or airport desk line while continuing to monitor updates.
Why: Seats on alternative flights can disappear quickly during disruption, so acting early improves your options.
- 6
Keep evidence of the disruption
Save screenshots of the flight status, emails, texts and any notices in the app. Keep receipts for reasonable expenses if the airline instructs you to arrange food, transport or accommodation yourself, and keep boarding passes and booking confirmations.
Why: If you later need reimbursement, a refund or compensation where applicable, clear records make the process much easier.
Why this works
Airlines control the booking record and operational decision on whether a specific flight runs, while airports provide local departure information such as terminal and gate changes. Using both gives you the best picture and reduces the risk of acting on stale or incomplete information.
Common mistakes to avoid
- Relying only on a third-party flight-tracking app instead of checking the airline directly
- Checking once early in the day and assuming nothing will change
- Going to the airport late because of a small delay without explicit guidance from the airline
- Ignoring emails or texts from a travel agent because you booked through an intermediary
- Failing to save receipts and screenshots after a cancellation or long delay
Troubleshooting
The airline app shows no update, but social media says flights are cancelled
Treat social media as unconfirmed until the airline or airport publishes an official update. Keep checking the airline app, website and email, and contact the airline if departure is close.
The airport website says delayed, but the airline still says on time
Monitor both, but follow the airline for booking and rebooking instructions. Leave for the airport according to the airline’s normal check-in guidance unless the airline tells you not to.
You booked through a travel agent and have not heard anything
Check the airline status directly using the flight number, then contact the agent as well for ticket changes they may need to process.
You cannot log in to the airline app
Use the public flight status page with your flight number, search your email for the booking reference, or call the airline if online access fails.
Your flight number has changed after a schedule update
Search by booking reference in the airline system rather than relying only on the original flight number.
Compare your options
Airline app or website
Best for: Real booking-specific status and rebooking actions
Pros: Most authoritative for your ticket; may offer alerts, refunds and rebooking
Cons: Can be slow or overloaded during widespread disruption
Airport website or departure screens
Best for: Terminal, gate and local departure information
Pros: Useful cross-check; often clearer for on-the-ground updates
Cons: Usually cannot manage your booking or show your rebooking options
Third-party flight trackers
Best for: General monitoring and convenience
Pros: Easy to use; may aggregate aircraft movement and route history
Cons: Not the final authority for your booking; updates may lag or differ from airline messages
| Option | Best for | Pros | Cons |
|---|---|---|---|
| Airline app or website | Real booking-specific status and rebooking actions | Most authoritative for your ticket; may offer alerts, refunds and rebooking | Can be slow or overloaded during widespread disruption |
| Airport website or departure screens | Terminal, gate and local departure information | Useful cross-check; often clearer for on-the-ground updates | Usually cannot manage your booking or show your rebooking options |

Alternatives
- Call the airline’s customer service line if online systems are unavailable
- Ask airport information staff where to confirm the latest departure information once you are on site
- If travelling for work, ask your corporate travel desk to monitor the booking
Pro tips
- Save the airline app before travel rather than downloading it during disruption
- Use the flight number as well as the route, because airports may list several flights to the same destination
- Take a screenshot of any cancellation or delay notice before the app refreshes
- If the airline offers automatic rebooking in the app, review the new itinerary carefully before accepting it
- Keep your phone charged; disruption handling often depends on app messages and digital boarding passes
Safety notes
- Do not rush to the airport based on rumours or leave home too late based on unofficial sources
- If you are already at the airport, follow staff instructions and airport safety announcements during disruption
- Protect your personal data when using public Wi-Fi; use official apps and websites only
Legal & regulatory notes
Passenger rights depend on where the flight departs from, which airline operates it and the reason for the disruption. In the UK and EU, rights may include care, rerouting or refund, and possible compensation in some circumstances. Check the relevant civil aviation authority or official passenger-rights guidance for the rules that apply to your journey.
What this guide does not cover: This guide explains how to check whether a flight is delayed or cancelled and what to do next at a practical level. It does not give case-specific legal advice or guarantee entitlement to compensation, refunds or reimbursement.
Cost considerations
Delays and cancellations can create extra costs such as food, transport, accommodation or replacement tickets. Before spending money, check whether the airline is providing assistance or requires pre-approval, and keep receipts in case you need to claim reimbursement. Travel insurance may also help, depending on the policy terms.
Frequently asked questions
Is the airline app better than a flight-tracking app?+
Yes for decision-making. Flight-tracking apps are useful, but the airline app or website is the best source for your booking status, alerts and rebooking options.
Should I still go to the airport if my flight is delayed?+
Usually yes, unless the airline specifically tells you not to. Delays can shorten, and check-in or bag-drop deadlines may still apply.
How do I know if a flight is cancelled rather than just delayed?+
Look for clear wording in the airline app, website, email or text. A cancellation is normally stated directly and is often followed by rebooking or refund options.
What if I booked through a travel website?+
Check the airline for the live flight status, but contact the travel website or agent as well if they control changes to the ticket.
Can I claim compensation for a delayed or cancelled flight?+
Possibly, depending on the route, the operating airline and the reason for the disruption. Check official passenger-rights guidance for your jurisdiction and keep evidence of the disruption.
