The airline is responsible for your bag, and you have the right to file a claim
When an airline loses your luggage, the airline is legally responsible for the contents up to a set limit. In the United States, that limit is $3,800 per passenger for domestic flights under federal law. International flights are covered under a separate treaty called the Montreal Convention, which sets a limit of about 1,350 Special Drawing Rights (roughly $1,800 USD, though the exact amount changes with currency rates).
The airline does not automatically pay you. You must file a claim with the airline within a specific timeframe — usually 21 days for domestic flights and 14 days for international flights, though some airlines allow longer. The airline will investigate whether the bag is truly lost or delayed, and if they confirm it is lost, they will ask you to provide receipts or proof of what was inside.
Your first step is to report the loss to the airline before you leave the airport. If you discover the loss later, contact the airline's baggage department as soon as possible. The sooner you report it, the sooner they can search their system and the sooner your claim important date begins.
Key Takeaways
- Report the lost bag to the airline at the airport or within 24 hours; waiting longer weakens your claim.
- Keep your baggage tag, boarding pass, and any written incident report the airline gives you — these are proof of what you checked.
- File a formal claim in writing within 21 days for domestic flights or 14 days for international flights; do not rely on verbal reports.
- The airline will ask for receipts or proof of the items inside; keep credit card statements, photos, or purchase records that show what you owned.
- If the airline denies your claim or offers less than your loss, you can dispute it or pursue small claims court, depending on the amount.
What to do at the airport when ready after discovering the loss
Do not leave the airport without reporting the bag to the airline's baggage office. Ask to speak to a supervisor if the first agent is dismissive. Tell them your bag did not arrive on the carousel or was damaged when it arrived. The airline will open a baggage report and give you a reference number — write this down and ask for a printed copy.
Ask the airline whether they will search for the bag and how you will be notified if they find it. Some airlines search for 30 days; others search for longer. Ask for the direct phone number and email address of the baggage department so you can follow up without going through the main customer service line.
If you need when ready items — medications, glasses, or clothes for the next day — ask the airline whether they will reimburse you for emergency purchases. Some airlines have a policy for this; others do not. Get the answer in writing if possible, or ask the agent to note it in your baggage report.
How to file a formal claim with the airline
After you leave the airport, file a written claim with the airline. Do not rely on the baggage report alone — that is an incident report, not a claim. Send your claim by email or certified mail to the airline's claims department. Include your baggage reference number, flight number, date of travel, and a detailed list of what was in the bag.
For each item, write down the type of item, when you bought it, and what you paid for it. If you have receipts, credit card statements, photos, or warranty documents, attach copies. The airline will use these to verify the value. If you do not have receipts, explain what the item was and estimate its value based on what a similar item costs new.
Include a copy of your boarding pass and baggage tag. State the total amount you are claiming. The airline will respond within 30 to 60 days, though this varies by airline. Some airlines respond faster; others take longer.
What happens if the airline finds your bag later
If the airline locates your bag within a few days, they will contact you and arrange delivery. You do not owe them anything for finding it. If the bag arrives damaged, take photos of the damage before opening it, and report the damage to the airline within 14 days. You can then file a damage claim using the same process as a loss claim.
If the airline finds your bag weeks later, after you have already filed a claim and received payment, contact the airline when ready. Most airlines will ask you to return the payment or will deduct the reimbursement from a future claim. Read the terms of your settlement to understand what happens if the bag is found.
Understanding the airline's liability limits and what they will not cover
The airline's liability limit ($3,800 for domestic US flights) applies to the total value of everything in your bag, not per item. If your bag contained a $5,000 camera, the airline will not pay the full value — they will pay up to the limit. This is why it is important to know the limit before you travel and to consider purchasing baggage insurance if you are carrying high-value items.
The airline will not pay for items they consider high-risk or fragile, such as jewelry, electronics, cash, or important documents. Some airlines exclude these items entirely from coverage. Check your airline's baggage policy before you travel to see what is and is not covered.
The airline will also deduct depreciation from the value they pay you. A suitcase you bought five years ago will not be reimbursed at its original price — the airline will estimate what it is worth now, used. The same applies to clothing, shoes, and other items. This is called the "depreciated value," and it is usually much less than what you paid.
What to do if the airline denies your claim or offers too little
If the airline denies your claim, they must give you a reason in writing. Common reasons include: the bag was not actually lost (they claim you picked it up), the items you listed were not in the bag, or the value you claimed is too high. Read their letter carefully and decide whether you agree with their reasoning.
If you disagree, you can file a dispute with the airline's appeals department. Send a letter explaining why you believe their decision is wrong, and include any new evidence — such as witness statements, additional receipts, or photos of the bag. Give them 30 days to respond.
If the airline still refuses to pay or offers less than you believe is fair, you can pursue the claim in small claims court. The amount you can recover in small claims court varies by state, but most states allow claims up to $5,000 or $10,000. You will need to bring your evidence — receipts, photos, the airline's written responses, and any other documentation. You do not need a lawyer for small claims court, though you can hire one if you choose.
Whether baggage insurance is worth buying
Baggage insurance covers the gap between what the airline will pay and the actual value of your items. If you are traveling with expensive electronics, jewelry, or other high-value items, baggage insurance can protect you if the bag is lost. The cost is usually $10 to $30 per trip, depending on the coverage amount.
Some credit cards include baggage insurance as a cardholder benefit. Check your credit card's terms to see whether you already have coverage. If you do, you do not need to buy additional insurance. If you do not have coverage and you are carrying items worth more than the airline's liability limit, baggage insurance is worth considering.
Read the fine print of any baggage insurance policy before you buy it. Some policies have exclusions similar to the airline's — they will not cover jewelry, cash, or electronics. Others cover these items but charge a higher premium. Make sure the coverage limit is high enough for what you are carrying.
Frequently Asked Questions
How long does the airline have to search for my bag?
Most airlines search for 30 days, though some search longer. Ask the airline's baggage department for their specific timeline when you report the loss. If they find the bag after you have filed a claim and received payment, contact them when ready to discuss what happens next.
Can I buy replacement items while the airline investigates my claim?
Yes, but keep all receipts. The airline will not reimburse you for replacement purchases unless you have proof of what you bought and what you paid. Some airlines have a policy for emergency purchases made at the airport, but most do not cover shopping you do after you leave.
What if I cannot find receipts for the items that were in my bag?
You can still file a claim. Explain what each item was and estimate its value based on what a similar item costs new. Use credit card statements, bank records, or photos as supporting evidence. The airline may offer less than you claim if you cannot prove the original cost, but they cannot refuse to consider your claim.
Do I need a lawyer to dispute the airline's decision?
Not for small claims court. You can represent yourself and present your evidence to a judge. If the amount is larger and you want to pursue it in regular court, you may want to consult a lawyer, though many will not take baggage cases because the amounts are usually small.
What if the airline says my bag was never checked in?
Ask the airline to search their system for your baggage tag number. Your boarding pass should show that you checked a bag. If the airline cannot find a record of your bag in their system, ask for a written explanation. You can then dispute this in your claim or escalate to the airline's management.
