If you’re flying with KLM Royal Dutch Airlines and your baggage is missing or damaged, you’re protected by the airline’s policies as well as international law. But to use those protections and secure compensation, you need to know exactly what to do and when to do it.

This guide explains how KLM handles delayed, lost, and damaged baggage, rights, and how to make sure your claim isn’t denied. 

Your Baggage Rights as a U.S. Passenger on KLM Flights

KLM routes involving the United States are covered by the Montreal Convention (1999), the international treaty that holds airlines financially responsible for mishandled baggage. So, if your checked bags are delayed, lost or damaged, KLM has the responsibility of compensating you for as much as $2,080 USD per passenger depending on exchange rates.

If Your KLM Baggage Is Delayed

Delayed baggage is the most common issue KLM passengers face. The first thing you should do if you don’t see your baggage on the carousel, is make a report while you're still in the arrivals hall.

How to report a delayed bag

KLM requires passengers to file a Property Irregularity Report (PIR) within 48 hours of your arrival. You can do this online in most countries, but if you arrive in the UK, you’ll need to report it directly at the baggage desk before leaving the airport.

Once the report is filed, you'll be given a (PIR) number, also called a file reference number. This number is important because it allows you to track your bag’s search progress, update your address for delivery once it’s found, and eventually file a compensation claim if needed.

After 24 hours have passed, you can check the real-time status of your bag using KLM’s online tracking system.
If your bag has an Apple AirTag, you can even share the live tracking link with KLM to help them locate your belongings more quickly.

If your bag hasn’t been found within 21 days

KLM classifies your bag as lost after 21 days, at which point you can move forward with reimbursement or compensation claims.

Reimbursement for Delayed Baggage 

If you had to purchase clothing, toiletries, or other essential items while waiting for your suitcase, KLM will reimburse you for these extra costs, but only if you keep receipts and submit your reimbursement request on time.

You have 21 days from the date your bag is returned to you to request reimbursement.

According to the rules of the Montreal Convention, the airline should reimburse these purchases as long as they’re truly necessary and directly related to the baggage delay.

If Your KLM Baggage Is Damaged

If you see that your bags are damaged, you should submit a Property Irregularity Report (PIR) immediately at the airport’s baggage service desk. 

If you’ve already left the airport, you can still report the damage, but you have to do so within 7 days of arrival.

Be sure to include:

• Photos of the damage from all angles
• Images of the baggage tag
• The brand name clearly visible
• A copy of the purchase receipt if available

After you file your report, KLM may choose to repair the bag, replace it, or reimburse you depending on the severity of the damage and the bag’s original value.

Which KLM Routes Are Most Likely to Face Baggage Issues?

Based on AirAdvisor’s internal data, most KLM baggage problems occur on journeys that pass through Amsterdam Schiphol (AMS), the airline’s main global hub. 

Schiphol handles enormous volumes of luggage every day, and most of the issues in our data appear during tight connection rather than on direct flights.

The routes with the highest number of mishandled bags in our dataset were flights arriving into Amsterdam from nearby European cities, including:

• Manchester
• Edinburgh
• Stockholm
• Lisbon
• Bucharest
• Hannover

We also saw delayed or misrouted baggage on longer inbound flights to Amsterdam, such as:

• Riyadh (RUH) to AMS
• Osaka Kansai (KIX) to AMS

These patterns make sense because bags arriving from short-haul European services or long-haul intercontinental flights usually need to be resorted quickly for onward connections. When the inbound aircraft arrives late or the layover window is very short, bags are more likely to fall behind and arrive on a later flight.

In short, the KLM journeys most prone to baggage delays are those involving a connection through Amsterdam Schiphol, especially when arriving from European feeder routes or long-haul flights with heavy bag loads.

How to File a Baggage Claim with KLM

You cannot file a compensation claim unless you first file a PIR report. Once that’s done, KLM’s online forms allow you to submit claims for:

• Essential items purchased due to a delay
• Compensation for lost baggage
• Compensation for severe damage

Each submission requires your PIR reference number, receipts, and in some cases a list of your bag’s contents.

The Montreal Convention deadlines for filing compensation claims are:

• 21 days to claim reimbursement for delayed baggage expenses
• 7 days to claim compensation for damaged baggage
• Lost baggage must be claimed after day 21 and within a “reasonable timeframe”

If you miss these deadlines, the airline can legally deny your claim.

When KLM Doesn’t Respond or Refuses Compensation

Sometimes passengers face long delays, incomplete responses, or having their baggage claim rejected. If that happens, you can escalate your case through KLM’s customer service channels and request a formal reevaluation, especially if you filed within the required deadlines

If your efforts fail, or if you prefer not to file a claim by yourself, let AirAdvisor handle the process for you. Airlines tend to respond more quickly when a specialized service is involved, and AirAdvisor ensures that your claim is prepared with the correct legal framing and documentation.

How AirAdvisor Helped a KLM Passenger Get Baggage Compensation

In July 2025, a KLM passenger flying to Montpellier (MPL) arrived to find that their checked baggage hadn’t made it onto the flight. The traveler filed a report, but when days passed with no update, they turned to AirAdvisor for help.

What We Did: We reviewed the passenger’s Property Irregularity Report (PIR) and the communications they had already exchanged with KLM. Because this was an international itinerary, the claim fell under the Montreal Convention, which requires airlines to reimburse passengers for essential purchases and compensate them if baggage is delayed or lost.

Our team:

• Collected documentation and verified all deadlines had been met
• Helped the traveler prepare an itemized list of the bag’s contents
• Ensured receipts for necessities (toiletries, clothing, personal items) were properly submitted
• Communicated directly with KLM to speed up the processing timeline
• Ensured the final settlement aligned with the Convention’s compensation standards

The Outcome: Within 43 days, the claim was fully resolved and KLM issued compensation for the mishandled baggage. The passenger was reimbursed for their emergency purchases and received an additional settlement for the baggage delay and losses, all without having to negotiate with the airline themselves.
