An effective lost baggage dispute letter asks for a specific amount, connects each amount to evidence, and separates a checked-bag fee refund from compensation for the bag itself. Use the template below after reporting the problem through the airline's baggage service or claims channel.
For a US domestic itinerary, DOT baggage rules and the airline's contract usually control. For an international itinerary, the Montreal Convention may control. The applicable liability limit is a ceiling, not a guaranteed check.
Thing is, EU261 is often pasted into baggage letters even though it mainly addresses flight disruptions such as qualifying delays, rerouting, meals, and hotels. It does not create a universal flat payment for a missing suitcase. This guide covers checked bags and general consumer information, not legal advice.
Which rule controls your baggage claim
The itinerary matters more than the airline logo. First identify where the journey began and ended, whether it crossed an international border, and whether every flight was on one ticket.
| Situation | Main rule or process | What to request |
|---|---|---|
| US domestic checked bag that is delayed, lost, or damaged | DOT baggage rules and the airline's contract of carriage | Documented eligible loss, plus a checked-bag fee refund when the applicable rule requires it |
| International itinerary | Montreal Convention and the carrier's contract | Documented loss, damage, or delay subject to the Convention's limits and deadlines |
| Qualifying flight delay or cancellation involving an EU itinerary | Regulation 261/2004 and related passenger-rights rules | Any separate flight-disruption remedy for which you qualify |
| Bag tracking or a property irregularity report, or PIR | Airline operating process | A report number, tracing record, and written claim history |
The DOT baggage guidance covers US airline responsibilities and complaint information. For international baggage liability, review the EUR-Lex summary of air carrier passenger and baggage liability.
A baggage report, tracking app, or IATA-related tracing process can help locate the suitcase. None of those tools decides the amount the airline owes.
Collect the evidence before writing
Your claim should be easy to audit. Gather these records first:
- The baggage report or PIR number, bag tag number, flight details, and itinerary
- Boarding passes, booking confirmation, and the airline's claim reference
- An itemized list of missing or damaged property, including purchase dates when known
- Receipts for necessary purchases made during the delay
- Photos of the bag, damage, tags, and any delivery or collection notice
- The airline's emails, claim decision, denial, and earlier correspondence
Keep the originals. Send copies through the airline's approved channel, and remove unnecessary account or payment-card numbers.

Subject: Dispute and reimbursement request - [claim/PIR number], [flight and date]
Dear Claims Team,
I am asking you to review my baggage claim for flight [number] from [origin] to [destination] on [date]. My bag tag number is [number], and my baggage report or claim reference is [number].
The bag was [delayed, lost, or damaged]. I reported the problem on [date] at [airport or online]. [State when it was delivered, or state that it remains missing.]
I request the following:
Checked-bag fee refund: $[amount], if applicable.
Essential purchases: $[amount], supported by the attached receipts.
Lost or damaged property: $[amount], based on the attached inventory and proof of value.
Other documented amount: $[amount], for [brief reason].
Total requested: $[amount]
For a US itinerary, please assess the checked-bag fee refund under 14 CFR 260.5 if its conditions apply. For an international itinerary, please treat this as my written baggage complaint under the applicable Montreal Convention rules.
Please review the attached records and confirm the claim status in writing. If you deny any line item, identify the item, the reason, and the rule or contract term you relied on.
Attachments: [list the documents]
Sincerely,
[Your name]Do not demand the maximum liability amount just because a template mentions it. Ask for the documented amount you can support.
How to file the claim and preserve your rights
Follow the airline's process first. The letter strengthens that claim; it does not replace the airline's required form.
- Report the missing or damaged bag promptly. Ask for a baggage report or reference number before leaving the airport when possible. If you already left, use the airline's official online or telephone channel.
- Submit the carrier's claim form. Enter the same flight, bag-tag, and contact details in your letter. Inconsistent information can slow review.
- Separate the amounts. List the checked-bag fee, necessary purchases, the bag or contents, and any repair cost as different line items.
- Keep buying reasonable essentials only. Save itemized receipts and explain why each purchase was necessary during the delay.
- Check the deadline for your itinerary. International Montreal Convention claims generally require written notice within seven days for damage and within 21 days for delay. A bag that remains undelivered for 21 days is generally treated as lost under the Convention. Domestic airline deadlines can differ, so do not rely on a universal 120-day rule.
- Send the letter through a trackable channel. Save the confirmation page, email, claim number, and the date submitted.
- Escalate after the airline responds or stops responding. US consumers can use the DOT's complaint information after giving the airline a fair chance to resolve the claim.
Report the problem immediately. Deadlines matter.
Ask separately for the checked-bag fee refund
Turns out, a fee refund and a baggage-loss reimbursement are different requests. Under 14 CFR 260.5, the refund for a checked-bag fee must be at least the amount paid when the rule applies and its conditions are met.
The rule addresses passenger notice, carrier notice, and automatic refunds. It also includes exceptions. For example, the outcome can be affected if a passenger failed to collect and recheck a bag at the first US international entry point when required, or voluntarily agreed to travel without the bag on the same flight.
| Claim line | Useful evidence |
|---|---|
| Checked-bag fee refund | Baggage-fee receipt, booking record, and claim number |
| Essential purchases | Itemized receipts, purchase dates, and a short explanation |
| Contents of a lost bag | Inventory, proof of purchase or value, and photos |
| Damaged bag or belongings | Photos, repair estimate, and replacement details |
The fee refund does not automatically pay for the contents. Request both when the facts support both.
Appeal a denied baggage claim
To be honest, the strongest appeal is usually shorter than the original complaint. Quote the denial, answer its specific reason, and attach one useful document for each disputed point.
Subject: Appeal of baggage claim [number]
I appeal the decision dated [date], which denied [item or amount] because [reason given by airline]. The attached [receipt, baggage report, inventory, or photo] addresses that reason. Please reconsider reimbursement of $[amount]. If you maintain the denial, please identify the specific rule, contract term, or missing evidence supporting it.
Do not simply resend the same story. Explain what changed.
For a US claim, review the DOT baggage information and follow its current consumer complaint instructions if the airline does not resolve the issue. A DOT complaint is an escalation route, not a guaranteed award or a substitute for a court decision.
A high-value international claim can involve liability limits, governing law, and strict Convention deadlines. Consider qualified legal help before filing a court action.
Mistakes in generic baggage templates
| Weak wording | Better wording |
|---|---|
| “Pay me $3,800 automatically.” | Request the documented loss and check the applicable liability limit for the itinerary. |
| “EU261 guarantees EUR 600 for my suitcase.” | Assess any EU flight-disruption claim separately from the baggage claim. |
| “The PIR proves the airline owes me.” | Use the report as evidence of notice and connect it to receipts and the requested amount. |
| “I have 120 days everywhere.” | Check the carrier's stated deadline and any international Convention deadline. |
| “IATA rules require this payment.” | Identify the actual DOT rule, Convention provision, or contract term that applies. |
| “The airline owes the retail price of everything.” | List reasonable, documented loss and explain the value of older or used items. |
The common $3,800 figure found in older online templates is not an automatic payout. Do not copy it without checking the itinerary and current applicable rules.
Questions about delayed and lost luggage claims
Can I claim the checked-bag fee and the cost of essentials?
Often, those are separate claim categories. Request the fee refund where the applicable rule covers it, then list necessary purchases separately with receipts.
Does a baggage report prove that the airline must pay?
No. It helps establish that you reported the problem. The airline still reviews the cause, evidence, amount, and applicable limits.
What if the airline returns the bag after I buy clothes or toiletries?
Ask for reimbursement of reasonable, necessary purchases made during the delay. Include the receipts and the date the bag was returned.
When is a delayed bag considered lost?
For international carriage governed by the Montreal Convention, baggage that remains undelivered for 21 days is generally treated as lost. An airline may classify a file earlier under its own tracing process, so ask for the status in writing.
Do Delta and United need different dispute letters?
Their online forms and contact methods may differ, but the core evidence is the same. Use the airline's official claim channel, then attach the letter as a clear written explanation.
Start with the claim number, not a dollar figure. Copy the template, replace every bracket, attach the matching receipts, and save the submission confirmation.
