Report the loss before you leave the airport

The moment you realize your bag did not arrive, go to the airline's baggage service office in the airport terminal—do not leave the airport first. This office is usually near baggage claim or the customer service desk. Tell them your flight number, destination, and a detailed description of your bag: color, size, brand, and any distinctive marks or damage.

The airline will ask for your contact information and create a Property Irregularity Report (PIR), sometimes called a baggage report. This document is your proof that you reported the loss on the same day. Ask for a copy before you leave—many airlines print it on the spot, though some email it later. Keep this report; you will need it for any claim you file.

Be specific about what was inside the bag. The airline will ask for a list of contents and their approximate value. If you cannot remember everything, write down what you can and add to the list later if you remember more items. Do not exaggerate values, but do not underestimate either—you will need receipts or photos to back up expensive items later.

Key Takeaways

  • Report your lost bag to the airline's baggage office before leaving the airport and get a copy of the Property Irregularity Report in writing.
  • The airline has up to 21 days to search for your bag; most lost luggage is found within the first week.
  • You can file a claim for the value of lost items, but you will need receipts, photos, or other proof of what was in the bag and what it cost.
  • Airlines limit how much they will pay per bag depending on the type of ticket you bought, so check your airline's policy before filing a claim.
  • If the airline cannot find your bag after 21 days, you can file a formal claim and request compensation for the contents.

Understand the airline's search window and what happens next

After you file the report, the airline has up to 21 days to search for your bag. During this time, the airline will check baggage handling areas, connecting airports, and lost-and-found systems. Most bags are found within the first week—many turn up at the airport where you were connecting or at your final destination, delayed by a day or two.

The airline will contact you if they find your bag. They will offer to deliver it to your home or hold it for pickup. If your bag is found, you do not pay for delivery in most cases—the airline covers it as part of their responsibility. If the bag arrives damaged, photograph the damage and report it to the airline in writing within 14 days of receiving it.

If your bag is not found after 21 days, the airline will declare it lost. At this point, you can file a claim for the contents. The airline will send you claim forms or direct you to file online through their website. This is when you will need the list of items, receipts, and photos you gathered.

Gather receipts and proof of what was in your bag

To support a claim, you need evidence of what you packed and what it cost. Start by collecting receipts for expensive items—clothing, electronics, toiletries, or anything else of value. If you do not have the original receipt, a credit card or bank statement showing the purchase can work. Photos of items before you packed them are also useful proof.

For items you cannot prove with receipts, write a detailed description and estimate a reasonable replacement cost. For example, if you packed five days of work clothes, estimate the cost of replacing a similar outfit from a store you shop at regularly. Be honest about the value—the airline will reject claims that seem inflated, and you may be asked to provide proof.

Keep all documents together in one folder or file. Take photos of receipts and documents so you have digital copies in case originals are lost. When you submit your claim, include everything that supports the value of your items.

Know the airline's payment limits for lost luggage

Airlines do not pay the full replacement cost of everything in your bag. The amount they will pay depends on the type of ticket you bought and the airline's policy. Most U.S. airlines limit payment to between $2,500 and $3,500 per bag for domestic flights. International flights have different limits set by international aviation law, usually around $1,600 per bag, though some airlines offer higher limits if you paid for premium coverage.

Check your airline's baggage policy on their website before you file a claim. Look for the section on "baggage liability" or "baggage compensation." The policy will tell you the exact limit for your type of ticket and flight. If you paid for a checked bag fee, that does not increase the liability limit—it just means you paid to check the bag.

Some airlines offer optional baggage protection or excess valuation coverage when you buy your ticket. If you purchased this, your coverage limit may be higher. Check your receipt or booking confirmation to see if you added this protection.

File your claim with the airline in writing

After 21 days, contact the airline and ask for the claim form. Most airlines have online claim portals on their website, usually under "baggage" or "customer service." Some airlines still accept paper claims by mail. Using the online portal is faster—you can upload photos and documents directly, and you will get a confirmation number when ready.

Fill out the form completely. Include your flight number, the date of travel, a description of the bag, the date you reported it lost, and your Property Irregularity Report number. List each item you are claiming, its description, the date you bought it, and the cost. Attach receipts, photos, and any other proof you have.

Submit the claim within the airline's important date, which is usually 45 days from the date your bag was declared lost. If you miss the important date, the airline may refuse to consider your claim. Keep a copy of everything you submit and note the date you filed it.

What to do if the airline denies or underpays your claim

The airline will review your claim and send you a decision, usually within 30 to 60 days. If they approve it, they will send payment by check or credit card. If they deny it or offer less than you claimed, you have options.

First, contact the airline's customer service department and ask why the claim was denied or reduced. Sometimes the decision is based on a misunderstanding or missing information. If you can provide additional proof, the airline may reconsider. Send a follow-up letter or email with the new information and ask them to review the claim again.

If the airline still refuses to pay or pays less than you believe is fair, you can file a complaint with the U.S. Department of Transportation (DOT) if you are in the United States. The DOT has a consumer complaint process for airline baggage issues. You can also pursue a claim in small claims court if the amount is within your state's limit, usually $5,000 to $10,000 depending on where you live.

Prevent future losses with packing and labeling strategies

While you cannot control whether an airline loses your bag, you can reduce the impact. Pack expensive items—medications, electronics, jewelry, important documents—in your carry-on bag instead of checked luggage. Airlines are not liable for items you carry on, so you keep full control.

Label your bag clearly inside and out. Use a luggage tag with your name, phone number, and email address on the outside. Inside the bag, write your contact information on a card or piece of paper. If your bag is found by someone else or by airport staff, they can contact you directly.

Take a photo of your packed bag before you check it. This photo serves as proof of what was inside if the bag is lost. Also photograph the luggage tag and any baggage claim stickers the airline gives you. These photos are valuable if you need to file a claim later.

Frequently Asked Questions

How long does it take to get paid after I file a claim?

Most airlines take 30 to 60 days to review and respond to a claim. If they approve it, payment by check or credit card usually arrives within two weeks. If they deny or reduce the claim, you may need to appeal or pursue other options, which can take several more months.

Can I buy new clothes or toiletries while waiting for my bag and ask the airline to pay for them?

Yes, you can buy essential items while your bag is being searched, and the airline may reimburse you for reasonable expenses. Keep all receipts and submit them with your claim. However, the airline will only pay for necessities—not luxury items or things you would have bought anyway. The total reimbursement is still subject to the airline's baggage liability limit.

What if my bag is found after I file a claim and receive payment?

If your bag is found after you have been paid, the airline will ask you to return the payment or let them keep the bag as compensation. Some airlines will let you keep both the payment and the bag if the delay was very long, but this varies by airline. Contact the airline when ready if your bag is found after a claim is settled.

Does travel insurance cover lost luggage?

Some travel insurance policies include baggage coverage, but not all. Check your policy documents to see what is covered and what the payment limit is. Travel insurance may cover items the airline does not, or it may pay a higher amount. File a claim with both the airline and your insurance company if you have coverage.

What if the airline says my bag is lost but I find it later at home or in my car?

If you receive payment from the airline and then find your bag, contact the airline when ready and return the payment. Keeping payment for a bag you have recovered is considered fraud. The airline may pursue legal action if you do not return the money.
