Flight Delay Compensation Letter Template — Free Download & Guide

A flight delay compensation letter is a formal request you send to an airline to claim money you are owed after a delayed flight. It states the facts of the delay, points to the law or airline policy that gives you the right to payment, and tells the airline exactly how much to pay and where to send it. You will also see this document called a delay compensation request letter, an EC261 compensation letter template, or simply a letter to an airline for delay compensation.

The letter is not a court filing. You can prepare it yourself in a few minutes, using the travel details and payment information you already have. This guide explains when the letter applies, what to include, how to fill it out correctly, and what to expect after you send it. A free flight delay compensation letter template is available for download.

When to Use a Flight Delay Compensation Letter

You use the letter when your flight arrived late enough to meet legal compensation thresholds — and the airline did not automatically pay you what you are owed. The letter functions as your formal demand, whether you are starting a claim or pushing one that has been ignored.

The compensation you can demand depends on the route and the legal framework that applies. Below are the main regimes, plus a quick comparison table so you can see which one covers your situation.

EU Regulation EC 261/2004

EC 261 covers flights that depart from an EU airport and flights that arrive in the EU on an EU‑based carrier. If your flight lands at the final destination three hours or more behind schedule, you are entitled to fixed cash compensation. The amount is set by distance: €250 for flights up to 1,500 km, €400 for flights between 1,500 and 3,500 km, and €600 for flights over 3,500 km. The regulation also gives you a right to care (meals, refreshments, accommodation and transport) during the wait, regardless of what caused the delay. Claiming this care does not cancel your right to cash compensation.

A common mistake is to confuse departure delay with the arrival delay that triggers payment. EC 261 uses the time the aircraft doors open at the final gate, not when the plane pushed back late. Always use the actual arrival time at your final destination.

UK 261 After Brexit

The United Kingdom has its own version of the EU regulation, often called UK 261. It applies to flights departing from a UK airport and flights arriving in the UK on a UK carrier. The compensation amounts are the same as EC 261, but expressed in pounds sterling. You cite “The Air Passenger Rights and Air Travel Organisers’ Licensing (Amendment) (EU Exit) Regulations 2019” or simply “UK 261” in your flight delay compensation letter.

US DOT Rules

The U.S. Department of Transportation does not require airlines to pay fixed cash compensation for domestic delays. However, most major U.S. carriers publish customer service plans that promise meal vouchers, hotel accommodation, or cash‑equivalent reimbursement after delays of three or four hours. A formal letter that quotes the airline’s own policy is often the only way to get those promises honoured. You can find the relevant commitment on the airline’s website.

Montreal Convention

This international treaty applies to carriage between states that are parties to it. Instead of a fixed amount, you can claim provable financial loss caused by the delay, up to a limit of approximately 4,694 Special Drawing Rights (SDRs) — roughly €5,600 or $6,100 at current exchange rates. There is no minimum delay threshold, but you must show receipts and evidence of the loss. The letter puts the airline on formal notice of your claim.

Quick Compensation Rules at a Glance

If, for example, your Paris–New York flight lands more than four hours late and the airline offered nothing, or a U.S. domestic delay strands you overnight and the airline’s own policy says it will reimburse a hotel, the flight delay compensation letter is the right tool. It works equally well as a printed document sent by certified mail or as a flight delay compensation email — simply copy the text into the message body and attach your supporting documents.

What to Include in Your Flight Delay Compensation Letter

Accuracy in every field keeps the claim moving. Missing even one key piece invites delay tactics. Use the checklist below to make sure your letter is complete before you send it.

Essential Information Checklist

A single missing field — especially the booking reference or a correct IBAN — is one of the most common reasons claims stall. Double-check every number against your travel documents and bank statement.

How to Fill Out a Flight Delay Compensation Letter

Filling out the letter takes just a few focused minutes. The steps below walk you through each part.

Step‑by‑Step Guide

1. Subject line – Write a clear subject that includes the flight number and date. Example: “Compensation claim – Flight AA104 on 15 March 2026 – Booking ABC123.”
2. Date and airline address – Insert the date of your letter and the postal address of the airline’s customer relations department. Even when emailing, include the date and address in the body.
3. Opening – Use “Dear Sir or Madam,” or the name of a specific representative if you have it.
4. State the facts – In the first paragraph, identify yourself as the passenger and give the flight details: date, flight number, route, booking reference (PNR) and scheduled times. Immediately state the exact length of the delay at the final destination, based on the doors‑open arrival time. Do not use the departure delay.
5. Demand for compensation – In the next paragraph, assert your right to payment. Name the applicable rule: “Under Regulation (EC) 261/2004, a delay of more than three hours on this route entitles me to compensation of €600.” If claiming under the Montreal Convention, list the total of your documented losses and attach receipts.
6. Provide payment details – Give your bank information in a separate short paragraph. Include the account holder’s name, IBAN or account number, and BIC for international transfers.
7. Closing – Politely ask the airline to process the payment within a fixed time, such as 14 days. Sign the letter and print your name.

Before You Send

Attach copies — never originals — of your boarding pass, any delay confirmation emails or text messages from the airline, and a screenshot from a flight tracker showing the actual arrival time. If you are claiming for multiple passengers on the same booking, attach a schedule listing each name and the compensation amount per person. Save everything as a single PDF if you are emailing the letter.

Once the letter is complete, keep a copy and proof of sending. The entire process from blank page to ready letter should take less than fifteen minutes.

Delay Compensation Letter vs. Other Airline Correspondence

It is easy to send the wrong document and receive a rejection that could have been avoided. The table below separates the four most common types of airline letters.

Note that cancellation and delay claims rely on different legal triggers. Under EC 261, a cancellation can entitle you to compensation even if the replacement flight arrives only slightly late, while a delay must cross the three‑hour threshold at the final destination. Stick to the flight delay compensation letter when your flight actually operated but arrived late.

Subject: Claim for compensation – Flight AA104 on 15 March 2026 – Booking Reference JKL6M3

Dear Sir or Madam,

On 15 March 2026, I was a passenger on flight AA104 from New York (JFK) to London (LHR). My booking reference is JKL6M3. The flight was scheduled to depart at 10:00 and arrive at 22:00 local time. The actual arrival time at London Heathrow was 02:15 on 16 March 2026, a delay of 4 hours and 15 minutes.

Under Regulation (EC) No 261/2004, a delay of more than three hours on this route entitles me to fixed compensation of €600 per passenger. I therefore request payment of this sum.

Please transfer the compensation to the following account:

Account holder: [Your Name]
IBAN: [Your IBAN]
Bank: [Bank name and address]
SWIFT/BIC: [BIC code]

I ask that you process the payment within 14 days of this letter. If you require any further information, you may contact me at the address or telephone number above.

Yours faithfully,

[Signature]

[Your printed name]

Key Annotations

• Passenger details and date – Use your legal name exactly as it appears on the booking. The letter date anchors the timeline.
• Subject line – Includes the flight number and date so the airline locates your reservation instantly.
• Facts paragraph – The booking reference (PNR) is non‑negotiable. Use the actual doors‑open arrival time at the final destination, even after a connection.
• Legal basis – Name the specific regulation and article. For EC 261 long‑haul claims, the amount is €600 per passenger regardless of the ticket price paid.
• Compensation amount – State a clear figure. If multiple passengers travelled on the same booking, give the total and attach a separate list of names and individual amounts.
• Bank details – Double‑check the IBAN and BIC. A single typo can cause a failed transfer.
• Closing demand – Requesting payment within 14 days is standard and prompts the airline to prioritise your file.
• Signature – Handwritten for postal mail; typed name works for email.

What Happens After You Send Your Flight Delay Compensation Letter

Once you press send or drop the envelope in the post, you move from preparation to monitoring. Knowing the typical timeline and your escalation options prevents frustration and missed deadlines.

Typical Airline Response Times

Some airlines process valid claims in a few weeks. Others deliberately stretch the process. A polite follow‑up email after four weeks can nudge things along, but do not send repeated demands too quickly — that can push your file to the bottom of the queue.

When to Escalate Your Claim

If you receive no reply after eight weeks, or the airline rejects your claim with a reason you believe is wrong, it is time to escalate. You can do this by contacting the relevant national enforcement body (NEB) or using an approved alternative dispute resolution (ADR) scheme. Both routes are free or low‑cost and do not require a lawyer.

Which body to contact depends on where the flight was departing from and which airline you flew. For EC 261 claims, you normally approach the NEB in the country where the incident occurred (the departure country) or, for flights into the EU, the NEB of the destination country. In the UK, the Civil Aviation Authority (CAA) handles complaints, and for ADR you can use services such as CEDR or AviationADR. Under the Montreal Convention, you may need to bring a claim in court, so keep evidence of all losses.

Watch Out for Time Limits

Limitation periods — the deadlines for taking legal action — vary sharply by jurisdiction:

• EC 261 claims: governed by national law. Spain gives you two years, Germany and France generally three years, England six years. Count from the date of the flight.
• Montreal Convention: you must start court proceedings within two years of the date of arrival.
• US airline policy claims: check the terms of the plan for any contractual time limit.

Because limitation rules can be complex, the safest strategy is to send your flight delay compensation letter as soon as you return home. Do not wait for months, even if you believe the airline will eventually pay.

Frequently Asked Questions

How long does a flight need to be delayed to get compensation?
Under EC 261 and UK 261, your flight must arrive three hours or more late at the final destination. US DOT rules do not set a federal cash trigger, but airline policies often apply after three to four hours. The Montreal Convention has no minimum delay time; you claim for actual financial loss you can prove.

What are the flight delay compensation amounts?
EC 261 and UK 261 pay €250/£220 for flights up to 1,500 km, €400/£350 for flights between 1,500 and 3,500 km, and €600/£520 for flights over 3,500 km. The Montreal Convention allows recovery of up to around 4,694 SDRs per passenger — about €5,600. For US domestic flights, the amount follows the airline’s own customer service plan.

What are the time limits for claiming compensation?
Limits depend on the country. EC 261 claims can expire after two to six years, depending on national law. Montreal Convention cases must reach court within two years of arrival. To be safe, send your letter as soon as possible after the delay.

Does the flight delay compensation letter need to be notarized?
No. A standard handwritten or electronic signature is all that is required. Notarization would add unnecessary cost and delay.

Is the letter legally binding?
No, it is a formal demand, not a judgment. It does not force payment, but it is a necessary step before escalation and shows that you gave the airline a chance to pay.

What is the best way to send the letter?
For a clear record, email the letter with scanned copies of your boarding pass and any delay confirmation. If you prefer postal mail, send it to the airline’s customer relations department by certified mail so you have proof of delivery.

How long does an airline take to respond?
Many airlines reply within four to eight weeks. Some take longer. If you hear nothing after eight weeks, you should escalate to the relevant national enforcement body or ADR scheme.

Can you get compensation when a delay is caused by weather?
Under EC 261 and UK 261, the airline does not have to pay cash compensation if the delay was caused by “extraordinary circumstances” that could not have been avoided. However, the airline must still provide care (meals, accommodation) even in those situations. A letter remains useful for claiming those out‑of‑pocket costs.

Common Pitfalls and Tips When Writing Your Flight Delay Compensation Letter

A correctly drafted letter dramatically shortens the time to payment. Small mistakes, though, can cause weeks of back‑and‑forth. Here are the pitfalls to avoid and the practices that get results.

Avoid These Costly Mistakes

• Using departure delay instead of arrival delay – EC 261 compensation turns on how late the doors opened at the final destination. If your flight took off two hours late but made up time in the air and arrived 2 hours 50 minutes late, you may not qualify.
• Omitting the booking reference – The PNR is the airline’s key to your itinerary. Without it, they may struggle to verify your flight and reject the claim on a technicality.
• Guessing the compensation amount – Check the distance band or airline policy before filling in the number. Overstating the sum can slow processing and reduce credibility.
• Incomplete or incorrect bank details – A wrong IBAN or BIC causes a failed transfer and restart. Copy the details directly from your bank statement.
• Leaving out the legal basis – A letter that simply asks for money without mentioning EC 261, UK 261, the Montreal Convention or the airline’s published policy is easy for the airline to dismiss.
• Failing to keep a record – Always save a copy of the letter, any attachments, and proof of postage or email delivery. If you later need to escalate, this paper trail is essential.

Pro Tips for a Faster Payout

• Attach a single, clean PDF that bundles the letter, boarding pass, delay confirmation, and a screenshot from FlightAware or a similar tracker. The easier you make it for the claims agent to see the facts, the faster they can approve.
• State a clear 14‑day payment window and follow up politely once if you hear nothing after three weeks.
• If you are claiming under an airline’s customer service plan, quote the exact clause and attach a copy of the relevant page. This turns a vague request into a precise demand.
• Use the airline’s own online claims form if one exists, but attach the full letter as the supporting document. This ensures your structured demand is in the system while complying with the airline’s intake process.

The flight delay compensation letter is a practical, no‑nonsense tool. Pay attention to the details in this guide, and you transform a complicated‑seeming claim into a straightforward administrative task that gets your money where it belongs — into your account.
