A delayed or cancelled flight can disrupt important plans and create unexpected expenses. Depending on your journey and the rules that apply, you may be entitled to a ticket refund, an alternative flight, assistance while waiting, reimbursement of eligible expenses, or financial compensation.

The first step is understanding which type of claim fits your situation. A refund is not the same as compensation, and an airline may owe you one benefit without automatically owing you all the others. Your rights depend on factors such as your route, the operating airline, the circumstances of the disruption and the applicable passenger-rights rules.

1. Understand the Difference Between a Refund and Compensation

Before contacting the airline, identify what you are asking it to provide. Refunds, expense reimbursement and compensation are different remedies, and each may have different eligibility requirements.

Ticket refund

A ticket refund returns money paid for a ticket or an eligible unused part of a journey. Depending on the applicable rules and booking terms, a cancellation or significant schedule change may allow you to reject the alternative offered and request a refund.

If you still need to travel, check your options before accepting a refund that could end your existing travel arrangement. If you booked through an agency or third-party seller, you may also need to follow its process for handling the ticket payment.

Expense reimbursement

Expense reimbursement means recovering eligible costs you paid because of the disruption. Depending on the circumstances and applicable rules, covered expenses may include reasonable meals, accommodation or transport while waiting for an alternative flight.

Keep itemised receipts and choose reasonable options. Not every expense is automatically reimbursable, and obligations differ between jurisdictions and situations.

Flight-delay or cancellation compensation

Compensation is a separate payment that may be available under particular passenger-rights laws. Eligibility can depend on the route, arrival delay, cancellation notice, alternative travel offered and the reason for the disruption.

A refund does not automatically establish that you qualify for compensation. Likewise, some passengers may have a compensation claim even if they eventually complete their journey.

2. Find Out Which Passenger-Rights Rules Apply

There is no single worldwide rule guaranteeing the same compensation for every delayed or cancelled flight. The protections available may depend on the departure airport, destination, operating airline, itinerary and applicable national or regional regulations.

For example, European and UK passenger-rights frameworks can provide fixed compensation in qualifying circumstances. US rules include refund protections for covered cancellations and significant changes when passengers do not accept the alternative transportation or credit offered. Other countries have their own aviation regulations and complaint procedures.

Before estimating what you can claim, establish the following:

• Your original departure airport and final destination.
• The airline that operated or was scheduled to operate the flight.
• Whether your journey was booked as one connecting itinerary or separate tickets.
• How long the delay lasted at your final destination, if you travelled.
• When you were informed about the cancellation or schedule change.
• The reason the airline gave for the disruption.

Do not rely on a compensation amount advertised for a different country or route. Passengers affected by similar delays may have different rights under different laws.

3. What to Do When Your Flight Is Delayed

A delay announcement may not tell you how long the disruption will last or what assistance is available. Stay informed, keep records and ask the airline about your options.

• Ask for an explanation: Request the stated reason for the delay and ask how updates will be communicated.
• Record the times: Save the scheduled departure and arrival times and, where possible, the actual times.
• Ask about assistance: Depending on the applicable rules and circumstances, the airline may have obligations relating to meals, communication or accommodation.
• Keep expense records: Save receipts for reasonable meals, transport or overnight accommodation you pay for yourself.
• Save communications: Keep emails, text messages, app notifications and written explanations relating to the disruption.
• Ask before making major changes: If you plan to abandon the trip or buy another ticket, first clarify your options with the airline where practical.

Do not assume every delay automatically qualifies for cash compensation. Some rules require a particular arrival delay or other qualifying conditions, and the cause of the disruption may affect eligibility.

4. What to Do When Your Flight Is Cancelled

When an airline cancels a flight, you may be offered a refund, replacement flight or another arrangement. The choices available depend on the rules governing your journey and the circumstances of the cancellation.

Before accepting an offer, clarify:

• Whether you can choose a refund instead of travelling.
• Whether an alternative flight is available and when it departs.
• Whether assistance is available while you wait.
• Whether accepting a voucher affects the options available under the applicable rules.
• Whether you may separately qualify for compensation.

If you still need to reach your destination, ask the airline to explain its rerouting options before purchasing a replacement ticket yourself. You may find it more difficult to recover the cost of an independently purchased flight if you did not first establish your rights and available alternatives.

If you choose a refund, confirm which parts of the journey will be refunded and whether connecting or return flights are affected. A refund for one ticket does not automatically cover separate bookings made with another provider.

5. Check Whether You Qualify for Compensation

Compensation is not automatic. The relevant law may consider the arrival delay, cancellation notice period, alternative flight offered and cause of the disruption.

Under certain European and UK rules, qualifying passengers may receive fixed compensation based on factors such as flight distance and the circumstances of the disruption. Exceptions may apply, including circumstances outside the airline’s control, depending on the specific legal framework.

Other journeys may be governed by different standards. A long delay does not always guarantee compensation, and a cancellation does not necessarily result in a cash award beyond any refund that is due.

Questions to ask before submitting a claim

• Does the relevant passenger-rights law cover this flight?
• Did the delay or cancellation meet the eligibility conditions?
• How much notice did the airline provide?
• What reason did the airline give, and does an exception apply?
• Am I claiming a refund, expenses, compensation or more than one remedy?

If the answer is unclear, you can still submit a reasoned claim and ask the airline to explain its decision. Avoid treating any particular payment as guaranteed until your eligibility has been assessed.

6. Gather Documents to Support Your Claim

A well-organised claim is easier to assess than one based only on a verbal account. Collect documents showing your booking, the disruption and any additional expenses you want to recover.

• Your booking confirmation and ticket number.
• Boarding passes, where available.
• The original itinerary and any revised itinerary.
• Emails, text messages or notifications about the disruption.
• Evidence of the actual arrival time, if applicable.
• Itemised receipts for eligible expenses.
• Records of conversations with airline staff or customer support.
• Any reference number for a complaint already submitted.

Keep copies of the original documents and submit copies unless the airline specifically requires otherwise. Store your records securely and avoid sharing unnecessary personal or payment information.

7. Submit Your Claim to the Airline

In many cases, a practical first step is to use the operating airline’s official customer-service or claims process. If a travel agency sold your ticket, you may also need to contact the seller about refunds or booking-specific issues.

Make your request clear and specific. Include your booking reference, flight number, travel date, a brief explanation of the disruption and the outcome you are requesting.

If you are seeking more than one remedy, list each separately. For example, you might request an eligible ticket refund, reimbursement of documented expenses and compensation if the relevant passenger-rights rules provide for it.

Keep a copy of your submission and note the date it was sent. Save the case number or acknowledgement so you can follow up if the airline does not respond.

8. What to Do If the Airline Rejects Your Claim

A rejection does not always mean that you have no further options. Read the explanation carefully and identify whether the airline has rejected the claim because of eligibility, the cause of the disruption, missing documents or its interpretation of the applicable rules.

If you believe the decision is incorrect:

• Ask the airline to explain its decision in writing.
• Review the passenger-rights rules that apply to your route.
• Provide missing evidence or correct factual errors.
• Use the airline’s formal complaint or appeal procedure, if available.
• Consider escalating to the appropriate aviation regulator, consumer-protection authority, approved dispute-resolution body or court, where applicable.

Complaint deadlines and legal time limits vary. Check them promptly rather than assuming you can submit a claim at any time. If the amount is substantial or the situation is complicated, consider obtaining independent legal or consumer-rights advice.

9. Avoid Common Flight-Claim Mistakes

• Confusing refunds with compensation: They are different remedies and may have different eligibility rules.
• Discarding receipts: Missing evidence can make expense reimbursement harder to establish.
• Accepting an offer without reading its terms: Understand what a voucher or settlement covers before agreeing.
• Buying a replacement ticket too quickly: Ask the airline about available alternatives and document why an urgent independent purchase was necessary.
• Assuming every delay qualifies: Check the applicable rules and the cause of the disruption.
• Ignoring claim deadlines: Keep track of submission dates and relevant legal time limits.
• Paying an unverified claims company upfront: Check its fees, contract terms, authorisation and whether you can claim directly.
