How to File a Claim for Delayed or Damaged Luggage in 2026

I stood at baggage claim in Frankfurt, watching the carousel spin empty. My flight from Chicago had landed three hours earlier, but my checked bag—a medium-sized hard-shell suitcase with a red ribbon I'd tied on the handle—hadn't made it. The airline's kiosk agent shrugged and handed me a form. "Fill this out online," she said. "We'll call you." That call never came. Over the next two weeks, I learned exactly how to file a claim for delayed or damaged luggage—the hard way. If you're reading this in 2026, the process hasn't changed much, but the stakes are higher than ever: airlines are handling record numbers of bags, and delays and damage are up. This guide walks you through every step, from the airport to the final check, so you don't leave money on the table.

Step 1: Document Everything at the Airport — Before You Leave the Baggage Area

When your bag doesn't show up or arrives with a torn seam and missing wheel, your first instinct might be to rush to the customer service desk and vent. Resist that urge. What you do in the first fifteen minutes can make or break your claim.

First, stay at the baggage claim area. Every airline has a baggage service office (BSO) nearby, often tucked behind a door or counter. Walk there immediately. Do not leave the airport without filing a Property Irregularity Report (PIR). This is the official document that records the problem. Without it, the airline has no obligation to investigate. Ask for a copy—paper or digital—and note the reference number. I once had an agent scribble a number on a sticky note, which fell out of my pocket. Don't be me. Save it in your phone's notes app and take a photo of the form.

Second, photograph everything. Take pictures of the damaged area—close-ups and wide shots showing the bag in context. If the bag is delayed, snap a photo of the empty carousel with the flight number visible on the overhead screen. This timestamped evidence is gold when the airline later claims the damage was pre-existing or the delay was only an hour.

Third, ask the agent what the airline covers for delayed bags. Some airlines hand out a “delay kit” with toiletries and a T-shirt. Others instruct you to buy essentials and submit receipts. Get this in writing or at least note the agent's name and the time. I once had a Delta agent at JFK tell me to “just keep receipts for everything” but didn't mention the $50 daily cap. I spent $200 on clothes and chargers, and they reimbursed only $50. Know the limits upfront.

Finally, if your bag is damaged and you're at your destination, don't accept a cash offer on the spot. Airlines sometimes lowball you with an immediate $100 offer to close the case. Politely decline and say you'll file a formal claim. They're banking on you being tired and eager to go home.

Step 2: Understand Your Rights Under the Montreal Convention and DOT Rules

You have more power than you think, but only if you know the rules. For international flights (including U.S. departures to foreign countries), the Montreal Convention governs baggage liability. This treaty sets a compensation cap of approximately 1,288 Special Drawing Rights (SDRs)—roughly $1,700 USD in 2026—for lost or damaged luggage. For delayed bags, the same cap applies, but you must prove your expenses were “reasonably necessary.” That means receipts for toothpaste and a change of clothes, not a new designer handbag.

For domestic U.S. flights, the Department of Transportation (DOT) doesn't set a fixed compensation amount. Instead, airlines set their own limits, which typically range from $1,500 to $3,500 for lost bags. However, the DOT requires airlines to acknowledge lost luggage after 21 days and pay the declared value if you provided a written declaration at check-in. That's a detail almost no one uses. If you're traveling with a $5,000 camera rig, declare it at the counter and pay a small fee—it shifts the liability cap upward.

The key deadlines are strict: Under the Montreal Convention, you have 7 days from delivery to file a claim for delayed luggage (the day your bag arrives) and 21 days for damage. For lost luggage, you must file within 21 days, but the airline usually waits 5–14 days before declaring it permanently lost. Domestic U.S. airlines often have similar windows, but check your specific carrier's policy—they vary. Miss these deadlines, and your claim is dead. I've seen travelers lose out because they thought “a few days late” wouldn't matter. It does.

One counter-intuitive insight: The Montreal Convention cap is per passenger, not per bag. If you check two bags and both are lost, you're still limited to the same ~$1,700 total. That's why travel insurance or credit card baggage protection (like from Chase Sapphire or American Express Platinum) is so valuable—they cover the gap, often up to $3,000 per bag.

Step 3: Filing the Formal Claim — What Airlines Need and When to Send It

Once you're home, the real paperwork begins. Most airlines let you file a claim online through their “Baggage” or “Customer Relations” portal. You'll need the PIR reference number, your boarding pass (or e-ticket receipt), baggage tag stubs, and receipts for any expenses you incurred. If your bag was damaged, include the photos you took at the airport. If it was delayed, list every item you bought and attach scanned receipts or clear photos of them.

Be specific when describing the bag's condition or the items inside. For damage, say “zipper broken on main compartment, wheel cracked, fabric torn 4 inches on bottom right corner” instead of “bag is broken.” For lost items, create an itemized list with approximate values—clothing, toiletries, electronics. Airlines rarely pay full replacement value, but a detailed list shows you're serious and helps the adjuster process your claim faster.

Timing is everything. File the claim immediately—within 24 hours if possible—even if you're waiting for the bag to be found. The clock starts ticking the moment you receive the bag (for damage) or the moment it was supposed to arrive (for delay). If you wait a week to file, the airline may argue the damage happened in your custody.

Track your claim religiously. Most airlines give you a case number. Call or check the status every 5–7 days. In my Frankfurt case, I called Lufthansa's baggage line three times before someone admitted my bag had been scanned at a warehouse but never forwarded. Persistence got it delivered four days later, but only because I kept pushing. Don't assume they'll call you.

One practical tip: If your bag is delayed and you need clothes for a business trip, buy what you need and keep the tags on. Some airlines require you to return the items if your bag arrives within 24 hours. I learned this the hard way when I cut tags off a shirt and had to argue with a claims agent who said the “purchase wasn't necessary.”

Step 4: What to Do If the Airline Denies or Lowballs Your Claim

You filed the claim, submitted the receipts, and waited. Then the airline emails you: “We regret to inform you that your claim has been denied” or “We are offering $150 as a gesture of goodwill.” Don't accept the first offer. That's a negotiation tactic.

First, appeal within the airline. Write a polite but firm letter or email referencing your case number and the Montreal Convention or DOT rules. Attach any evidence you missed—like photos of the empty carousel or a screenshot of the tracking showing the bag never moved. Airlines often reverse decisions if you show you know the law. I had a friend whose United claim was denied for a delayed bag until she cited the DOT's 12-hour rule for domestic flights; they paid her full $300 the next day.

Second, escalate to the DOT or your country's aviation authority. In the U.S., you can file a complaint with the DOT's Aviation Consumer Protection Division. They don't adjudicate individual claims, but they pressure airlines to respond. A DOT complaint often triggers a senior customer relations agent who has authority to settle. For international flights, you can contact the Civil Aviation Authority in the country where the incident occurred or the European Consumer Centre if it happened in the EU.

Third, use your travel insurance or credit card protection. If you booked the flight with a card that offers baggage delay or loss coverage, file a claim there too. These policies typically cover items the airline won't—like sentimental goods (jewelry, heirlooms) or electronics—and they pay faster. Just make sure you don't double-claim for the same expense. The airline's payout may reduce what your insurance will cover.

Finally, for high-value items like a laptop or camera, consider small claims court. The airline likely won't send a lawyer for a $1,000 case, and you can file without an attorney. It's a hassle, but I've seen it work when the airline stonewalls. One traveler I know got a $2,500 judgment against an airline for a damaged violin case he'd documented with photos and appraisals. The airline paid before the court date.

FAQ: Your Top Questions Answered

How long do I have to file a claim for delayed luggage?

For international flights under the Montreal Convention, you generally have 21 days from delivery to file for damage, and 7 days for delay. Domestic U.S. flights vary by airline but often have similar windows. Check your airline's policy—some require claims within 24 hours of the bag's arrival.

Can I claim compensation for both delayed and damaged luggage on the same trip?

Yes, if your bag was delayed and then arrived damaged, you can file separate claims for each issue. Just ensure you document the timeline and condition clearly. Keep the PIR from the delay and photograph the damage when the bag is finally delivered.

What counts as 'reasonable expenses' for delayed luggage reimbursement?

Typically, airlines cover essential items like toiletries, clothing, and chargers. Keep receipts for everything, and avoid luxury purchases unless necessary—airlines may cap daily amounts at $50–100. If you need a suit for a business meeting, buy it, but keep the tags and note the context.

Do I need travel insurance to claim for delayed luggage?

No, you can file directly with the airline without insurance. However, travel insurance often covers items the airline won't, like sentimental or high-value goods, and can speed up reimbursement. It's worth having a policy with baggage delay benefits (typically 6–12 hours) for extra peace of mind.

What if my luggage is permanently lost? How much compensation can I expect?

Under the Montreal Convention, the cap is roughly 1,288 Special Drawing Rights (around $1,700 USD) for international flights. Domestic U.S. flights have no set cap but airlines may offer up to $3,500 for proven losses. You'll need to provide an itemized list with values. For high-value items, declare them at check-in or rely on travel insurance.

Practical Takeaway: Filing a claim for delayed or damaged luggage in 2026 is a straightforward process if you act fast, document everything, and know your rights. Start at the airport, file within the deadlines, and don't accept the first lowball offer. Bookmark this guide before your next trip—it could save you hundreds of dollars and a lot of frustration.
