Airline Lost Luggage Compensation: What You're Owed and How to Claim It

Airlines mishandled over 26 million bags in 2024. Most come back within 48 hours — but when yours doesn't, a specific legal framework kicks in that entitles you to real money. The problem is that airlines know the process better than you do, and the system rewards passengers who give up early. This guide covers your actual rights, jurisdiction by jurisdiction, and the exact steps to claim what you're owed.

Delayed vs officially "lost" — the timeline that matters

The single most important thing to understand: your bag is almost certainly not "lost" — it's delayed. These are two very different legal states with different processes, timelines, and compensation amounts.

• Delayed bag: The airline knows your bag exists but it hasn't arrived on your flight. The airline is actively tracking it. This triggers interim expense reimbursement (toiletries, clothing) but not a full loss claim.
• Lost bag: After 21 days without delivery, the Montreal Convention classifies the bag as permanently lost. At this point you can file a full compensation claim.
• Some US carriers move faster: Airlines like Delta and American may declare loss after as few as 5–14 days. Check your carrier's Contract of Carriage for their specific timeline.
• Don't assume lost means gone forever: Airlines continue searching even after paying out a loss claim. Some passengers have had bags returned months later — and had to return part of the settlement.

The practical implication: for the first three weeks, you're in the delayed bag process. Focus on interim expenses, daily follow-ups, and documentation. The formal compensation claim comes after the 21-day mark.

Your legal rights: Montreal Convention, DOT rules, and EU 261

Three separate legal frameworks may apply to your situation depending on where you're flying. In some cases more than one applies — and you can layer them.

Montreal Convention (most international flights)

The Montreal Convention covers international flights between countries that have ratified it — which includes the US, all EU member states, UK, Canada, Australia, and most major travel destinations. It sets a maximum liability of 1,288 Special Drawing Rights (SDR) per passenger — roughly $1,700–1,800 USD at current exchange rates. Key points:

• The limit applies to the total claim per passenger, not per bag.
• This is a ceiling, not an automatic payment — you must document actual losses with receipts.
• Airlines can exceed the limit voluntarily, but are not required to.
• You have 21 days from when you should have received the bag to file a written claim. Missing this window may forfeit your rights.
• For delayed bags (not yet declared lost), you can claim documented interim expenses incurred during the delay.

US DOT rules (domestic flights)

For flights entirely within the United States, Department of Transportation rules apply. There is no federal monetary cap on lost luggage claims for domestic flights — but in practice, airlines set their own limits in their Contracts of Carriage, typically $3,500–$3,800. The DOT does mandate that airlines must accept and process claims, must offer compensation for significantly delayed bags, and cannot contract out of their obligations.

EU Regulation 261/2004 (flights departing from the EU)

EU 261 applies when your flight departs from an EU airport (regardless of airline) or arrives at an EU airport on an EU-based carrier. It primarily covers flight delays and cancellations, but it interacts with luggage claims in important ways. If delayed luggage caused a significant disruption — a missed connection, an overnight stranding — you may be entitled to additional compensation under EU 261 on top of the Montreal Convention claim. EU 261 compensation is fixed at €250–€600 depending on flight distance and is filed separately from the baggage claim, referencing the same PIR number.

The claim process step by step (starting at the airport)

The first 30 minutes at the airport are the most important. Everything you do here determines how easily you can claim compensation later.

1. File the Property Irregularity Report (PIR) before leaving the baggage hall. Once you clear customs, you cannot return to the secure side without a new boarding pass. The PIR activates the airline's search system and is required for any reimbursement.
2. Get the PIR reference number in writing — on paper or emailed to you immediately. Verbal references disappear. Every follow-up call starts with this number.
3. Photograph everything at the desk: the empty carousel, your boarding pass, the PIR form, the agent's name badge. These are timestamped evidence.
4. Ask specifically about the interim expense allowance. Most airlines offer $50–200 per delayed day for essentials. The agent may not volunteer this. Ask the amount, what's covered, and how to submit receipts.
5. Track via WorldTracer. This is the shared database airlines use globally. Log in with your PIR reference at your carrier's website — you'll see every scan your bag receives anywhere in the world.
6. Follow up every 24 hours. Call the delayed baggage line. The agent today didn't take your PIR; they'll check the file and may have updates not yet synced to the online portal.
7. After 21 days without delivery, file the formal loss claim in writing. Email is fine — you need a paper trail. Include your PIR number, an itemised list of contents with estimated values, and any receipts or photos you have.
8. If the claim is rejected or under-settled, escalate to the airline's customer relations department, then to the DOT (US domestic) or your national aviation authority. Small claims court is a legitimate next step for documented claims the airline refuses to honor.

What airlines must pay for — and what they won't

Airlines will try to exclude or limit claims for certain categories. Know these before you file.

Typically covered

• Clothing and general luggage contents, valued at depreciated replacement cost
• Toiletries and essentials purchased during a delay
• Reasonable interim transport costs if the delayed bag prevented travel as planned
• Some carriers cover sporting equipment damage or loss separately — check your carrier's Contract of Carriage

Typically excluded or limited

• Cash and negotiable instruments — almost universally excluded.
• Jewelry, watches, and precious items — airlines cap liability for these, often at a fraction of actual value.
• Electronics (laptops, cameras, tablets) — most carriers exclude or severely limit electronics in checked luggage. This is buried in the Contract of Carriage. Read yours before you fly.
• Medications and medical devices — airlines may cover some costs but not all. Prescription medication in checked luggage is a particular risk.
• Fragile items and antiques — carriers often disclaim liability for fragile contents.
• Business losses — consequential economic losses (a missed client meeting, lost revenue) are generally not recoverable from the airline.

The practical rule: anything irreplaceable, expensive, or essential goes in your carry-on. If it must be checked, photograph it before packing and consider travel insurance with baggage coverage for the gap.

Interim expenses: clothing and essentials while you wait

This is where most passengers leave money on the table. Airlines are obligated to reimburse reasonable out-of-pocket expenses incurred because your bag didn't arrive. "Reasonable" is in your favor more than airlines suggest.

• Toiletries and personal care items: toothbrush, toothpaste, deodorant, shampoo, razor — all reimbursable. Don't feel guilty buying the brand you actually use.
• Clothing: one or two changes of clothing per day of delay are typically accepted. Business travel with no suit? A replacement is a legitimate claim.
• Underwear and socks: completely reasonable. Buy them.
• Essential items that were in the bag — a phone charger, for example — are reimbursable if you can show they were packed.
• Keep every receipt. Most airlines require receipts in the original purchase currency. Digital photos of receipts are accepted by most carriers, but physical originals are stronger.

Submit interim expense claims as soon as the bag is declared delayed — don't wait for the bag to be found or declared lost. These are separate from the permanent loss claim and have shorter submission windows at some airlines.

Airlines often quote a per-day allowance at the counter (typically $50–200). This is a guideline, not a cap. If you incur higher documented costs due to the nature of your trip — a wedding, a business conference — document the reason and claim the full amount. Some airlines will pay above the standard allowance with adequate justification.

How to prevent lost luggage (and what makes a bag easier to return)

Compensation is the last resort. A bag that gets returned quickly — or never goes missing — is worth more than any settlement. These habits reduce both the risk and the recovery time.

1. Put a QR tag on the outside of your bag. When a handler or fellow passenger finds a bag, the first thing they do is look for an owner. A QR tag gives them instant contact — no app needed on their end, no personal data exposed. See how it works at the luggage tag setup page.
2. Put a second tag inside the bag. Outer tags get torn off. An inner sticker under the lid means the handler who opens the bag to identify it can still reach you directly.
3. Add an AirTag or similar tracker. This tells you where the bag is in the airport system — useful information when calling the airline. Pair it with a QR tag: AirTag shows location, QR tag enables contact.
4. Photograph every item before packing. A cloud folder with photos of each item is worth hundreds of dollars if you need to file a claim. Most passengers skip this and then can't document their losses.
5. Keep boarding passes for at least 90 days. They establish when and where you checked the bag.
6. Tag the bag with your hotel address, not your home address. Home address plus known travel dates signals an empty house. Hotel address means the airline delivers to where you actually are.
7. Check in online and arrive early. Late check-ins are more likely to miss connecting flights and arrive as bag-only loads, increasing mishandling risk.

A QR tag changes the calculus on delayed bags specifically. Most bags that go missing in transit are found — they're sitting in a sorting facility or on the wrong carousel. The question is how quickly the airline can close the loop between "we have this bag" and "we've contacted the owner." A QR tag on the outside means any airport employee who picks it up can reach you directly, bypassing the WorldTracer process entirely and cutting days off the recovery time.
