How to Write a Formal Demand Letter for Lost Luggage

PeakWanderer Editorial · Updated 2026

Every year, over 25 million pieces of luggage are reported lost or delayed by airlines worldwide, leading to significant inconvenience and potential financial loss for travelers. Under the Montreal Convention, passengers have rights regarding compensation for lost luggage, which can reach €1,400 (approximately $1,500). This article will guide you through crafting a formal demand letter to ensure you receive the compensation you deserve.

What Regulations Protect Your Rights Regarding Lost Luggage?

When your luggage is lost or delayed, the Montreal Convention (1999) comes into play for international flights, while regulations such as EU261 and UK261 apply to flights within Europe or departing from European airports. For instance, under the Montreal Convention, you can claim compensation for lost luggage up to approximately €1,400 (around $1,500) if you file your claim within 21 days of the incident. Airlines like British Airways and Air France are bound by these regulations, ensuring that you have a legal framework to support your claim.

How to File Your Claim: Step-by-Step Process

1. **Report the Loss**: Immediately report your lost luggage at the airline's baggage service desk upon arrival. Obtain a Property Irregularity Report (PIR).
2. **Document Everything**: Keep all receipts for necessary purchases made during the delay and document your communication with the airline.
3. **Prepare Your Demand Letter**: Write a formal letter including your contact details, flight information, and a clear statement of your claim.
4. **Send the Letter**: Mail your demand letter to the airline's claims department, ensuring you send it within the specified deadline.
5. **Follow Up**: If you do not receive a response within a reasonable timeframe, follow up via email or phone.

Your Legal Rights and Escalation Steps

If your claim is denied or you feel the compensation is inadequate, you can escalate the issue through various channels. Start by contacting the airline’s customer service again for clarification. If unresolved, consider submitting your case to an Alternative Dispute Resolution (ADR) scheme or an ombudsman if available. You can also file a claim in the small claims court (MCOL) for amounts under £10,000. When writing your escalation letter, use clear and concise language, citing the Montreal Convention and mentioning any previous correspondence.

Documentation and Evidence for Lost Luggage Claims

When filing a claim for lost luggage, it’s essential to document everything meticulously. Photograph your luggage before traveling, showing its condition and tags. Keep copies of your boarding pass and baggage claim ticket. Airlines typically accept claims with this documentation, but ensure you submit all evidence promptly. Some airlines may reject claims if supporting documents are missing, so double-check their specific requirements before submission.

Money: Interim Expenses and Claims

While your luggage is lost, you may incur reasonable expenses for necessities like clothing and toiletries. Always keep the receipts for these purchases, as they are necessary for reimbursement claims. Airlines often cover interim expenses, but there may be limits on how much you can claim based on their policies. Be aware that many airlines may refuse to cover depreciation on lost items, so document your original purchase prices when possible.

Specific Mistake or Special Circumstance

One common mistake that can undermine your claim is failing to report the missing luggage immediately at the airport. Always file a report with the airline's baggage service desk before leaving the airport. Additionally, if you have unique circumstances, such as traveling with valuable items, disclose this information upfront, as it may affect the handling of your claim.

Insider Tip: Always request a copy of the Property Irregularity Report (PIR) when reporting lost luggage, as this is crucial for your claim.

Documentation: Exactly What Evidence to Gather and Keep

When dealing with lost luggage, the strength of your claim often hinges on the evidence you can provide. Begin by taking clear photographs of your luggage, including tags and any distinguishing features, as visual proof of ownership. Keep all receipts for essential items you purchase while your luggage is missing, such as clothing and toiletries. Document the serial numbers of electronic devices and valuable items within your luggage, as these details can substantiate your claim. Additionally, maintain email timestamps from communications with the airline and retain your baggage claim tags. This documentation will bolster your case and can be pivotal in winning your claim.

Money: Interim Expenses and Depreciation Rules

Airlines are required to reimburse you for reasonable interim expenses incurred due to lost luggage. This typically includes costs for clothing, toiletries, and other necessities. However, they often impose strict limits on the amount they will cover. Be aware of the depreciation rules, which can affect compensation for lost items. The general formula used is the original purchase price minus a percentage for each year of use. Airlines may refuse to reimburse certain items, such as electronics, if they deem them to be beyond a reasonable age or condition. To counter this, provide proof of the item's condition and original value to argue for a fairer reimbursement.

Biggest Mistakes That Kill Lost Luggage Claims

Many travelers unknowingly sabotage their lost luggage claims through common mistakes. Submitting the wrong form, such as failing to use the airline's specific claim form, can lead to immediate denial. Missing the filing deadline is another critical error, as most airlines require claims to be filed within a certain timeframe—often within 21 days. Additionally, not following the correct escalation path can hinder your claim. Always start by contacting customer service, then escalate to a supervisor if necessary. Keeping detailed records of all interactions can also prevent misunderstandings and ensure your claim is processed effectively.

Insider Tip: Always request a “Property Irregularity Report” (PIR) at the airport. This document serves as an official record of your lost luggage and can be crucial for your claim.
