The airline is responsible for finding your bag or paying you for what was inside
When an airline loses your luggage, the airline must either locate and return it to you or compensate you for the contents. You are not stuck with the loss. The airline's liability is set by federal law, and your job is to document what happened, file a claim with the airline, and follow up until you get a response.
The process starts at the airport before you leave. If your bag does not arrive on the carousel, go directly to the airline's baggage service office—do not leave the airport without reporting it. The airline will ask you to describe the bag, list what was inside, and provide contact information. This report creates an official record and starts the search.
The airline has a legal obligation to search for your bag for a set period. During this time, you may need to buy essentials like toiletries, a change of clothes, or medications. Keep all receipts. Many airlines will reimburse reasonable expenses while they search, though you may have to ask and provide proof of purchase.
Key Takeaways
- Report your lost bag to the airline's baggage service office before leaving the airport, and get a written confirmation with a reference number.
- The airline must search for your bag and has up to 21 days to locate it; if found after that, they must still deliver it to you.
- Keep receipts for emergency purchases of clothing, toiletries, and medications while the airline searches, as these may be reimbursed.
- If the bag is not found, the airline's liability is capped at roughly $3,500 per passenger for domestic flights, though the exact limit depends on the airline and route.
- File a written claim with the airline within 30 days of the flight, include your receipts and a list of contents, and follow up if you do not hear back within 30 days.
What happens during the search period
After you file a report, the airline searches its system for your bag. This usually takes a few days. The airline will contact you if they find it and arrange delivery to your home or a location you choose. Many airlines deliver at no cost if the bag is found within a certain timeframe.
If your bag is not found within 21 days, the airline can declare it permanently lost. At that point, you move from the search phase to the claim phase. Some airlines will declare a bag lost sooner if they have strong evidence it will not be recovered—for example, if the bag was damaged beyond use or never made it onto your flight.
During the search, the airline may ask you for more details about the bag's contents or value. Answer these questions promptly and keep copies of everything you send. If the airline finds your bag after declaring it lost and paying your claim, you may be asked to return the compensation or keep it depending on the airline's policy.
How much the airline will pay
The amount the airline owes you is limited by federal law. For domestic flights within the United States, the limit is roughly $3,500 per passenger. For international flights, the limit is lower—roughly $1,500 per passenger—unless you declared a higher value when you checked the bag.
The airline does not pay the full limit automatically. They pay for the actual value of what was lost, up to the limit. This means you need to prove what was in the bag and what it was worth. New items are worth more than used ones. A five-year-old winter coat is worth less than a new one.
The airline will also deduct a percentage for depreciation—the loss in value over time. A two-year-old laptop is worth less than a brand-new one, even if both are the same model. The airline's calculation of depreciation can be aggressive, so if you disagree with their offer, you can push back with receipts or comparable prices from retailers.
Filing a claim with the airline
You must file a written claim with the airline within 30 days of your flight. Do not rely on phone calls or in-person conversations—send a letter or email to the airline's baggage claims department. Include your flight number, date of travel, baggage reference number (from your initial report), a detailed list of items that were in the bag, and the value of each item.
Attach copies of receipts for the items you listed. If you do not have original receipts, include credit card statements showing the purchase, photos of the items, or a written statement of what you remember buying and when. The more documentation you provide, the harder it is for the airline to dispute your claim.
Also include receipts for emergency purchases you made while waiting for your bag—the hotel toiletries, the shirt you had to buy because you had no clean clothes, the medications you needed. These are separate from the value of the lost items and should be listed separately on your claim.
What to do if the airline denies or lowballs your claim
If the airline denies your claim or offers less than you believe is fair, you have options. First, respond in writing with additional documentation. If you have new receipts, photos, or evidence of the item's value, send it to the airline with a letter explaining why their offer is too low.
If the airline does not respond within 30 days of receiving your claim, or if they refuse to budge after you have provided evidence, you can file a complaint with the U.S. Department of Transportation. The DOT has a consumer complaint system that puts pressure on airlines to resolve disputes. You can also pursue the claim in small claims court if the amount is within your state's limit—usually $5,000 to $10,000.
Some airlines have internal appeals processes. Check the airline's website or call their baggage claims department to ask if you can appeal their decision. An appeal gives you a chance to present new evidence or challenge their depreciation calculations.
Protecting yourself on future flights
You can reduce the risk of loss by packing valuables in your carry-on bag instead of checked luggage. Jewelry, electronics, medications, and important documents should never go in a checked bag. Airlines are not liable for valuables in checked bags, so if your bag is lost, you cannot claim them.
Take a photo of your bag before you check it, and photograph the baggage tag the airline attaches. This makes it easier to describe the bag accurately if it is lost and helps you prove ownership if there is a dispute.
Consider purchasing baggage insurance if you are traveling with expensive items or traveling internationally. Baggage insurance covers losses that the airline's liability limit does not, though you will pay a premium. Read the policy carefully to understand what is and is not covered.
What happens if your bag is found after you are paid
If the airline locates your bag after paying your claim, they will contact you. Some airlines ask you to return the compensation; others let you keep it. Check your airline's policy or ask when they contact you.
If the bag is damaged but usable, the airline may offer to repair it or give you a partial refund instead of replacing it. You can negotiate this offer if you believe the repair will not restore the bag to its original condition.
Frequently Asked Questions
How long does it take to get paid after I file a claim?
Most airlines respond to claims within 30 days. If they approve your claim, payment usually arrives within another 2 to 4 weeks. If they deny it or ask for more information, the timeline extends. If you do not hear back within 30 days, send a follow-up letter and consider filing a complaint with the Department of Transportation.
Can I claim items that were in my checked bag but not on my receipt?
Yes, but it is harder. You will need to describe the items and explain why you do not have receipts. A written statement of what you remember packing, when you bought the items, and what they cost helps. Credit card statements from around the time of purchase also support your claim. The airline may offer less for items without receipts because they are harder to verify.
What if I checked a bag with a connecting flight and it was lost on the second leg?
Report the loss to the airline at your final destination, not at the connection. The airline that operated the final flight is responsible for the bag from that point forward. If the bag was lost during the connection, you may need to file a claim with both airlines, but the airline operating the final leg usually handles the investigation.
Does travel insurance cover lost luggage?
Some travel insurance policies cover lost luggage, but not all. Check your policy before you buy it. Travel insurance baggage coverage usually has a lower limit than the airline's liability, so it may only cover the gap between what the airline pays and what your items were actually worth. Read the fine print to understand what is covered and what is not.
Can I claim for a lost bag if I packed it myself and did not use the airline's baggage service?
Yes. The airline is responsible for bags from the moment you hand them over at check-in, regardless of who packed them. The airline's liability does not depend on whether they packed the bag or you did. What matters is that you checked it with the airline and it did not arrive at your destination.
