Report the loss before you leave the airport

File a report with the airline's baggage office while you are still at the airport, before you leave the terminal. Do not wait to see if the bag shows up later — the moment you know it is missing, go to the airline's baggage desk or customer service counter. Bring your boarding pass and any baggage tags the airline gave you.

The airline will ask you to describe the bag, list what was inside, and provide contact information. They will give you a reference number and a written report. Keep this number; you will need it to track the claim and follow up. Ask the agent when the airline will contact you with an update — most carriers say 24 to 48 hours, though some bags take weeks to arrive.

If the bag is damaged rather than lost, report that damage at the same baggage desk before you leave the airport. Take photos of the damage and keep them with your report number. The airline's liability for damage is lower than for loss, and reporting when ready protects your claim.

Key Takeaways

  • Report a missing bag to the airline's baggage office before leaving the airport, and keep the reference number they give you.
  • The airline is liable for up to $3,800 per bag on domestic flights in the United States, though international flights have lower limits under international law.
  • You can claim reasonable expenses for essentials like toiletries and clothing while waiting for the bag, but you must keep receipts and provide them to the airline.
  • If the airline cannot locate the bag within 21 days, you can file a claim for the full value of the lost contents, though you may need to prove what was inside.

What the airline will cover and what they will not

U.S. airlines are required by federal law to compensate you for a lost bag up to $3,800 on domestic flights. International flights are covered under the Montreal Convention, which sets a lower limit of about $1,400 per bag. The airline's liability does not depend on the ticket price — it is the same whether you paid $100 or $1,000 for your flight.

The airline will not pay for the full replacement value of everything in the bag unless you can prove what was inside and what it cost. They will ask for receipts, credit card statements, photos, or other evidence. Items like jewelry, electronics, and cash are harder to prove and may not be covered at all, depending on the airline's policy. Check your airline's baggage policy on their website before you fly — most post their limits and exclusions there.

The airline will usually cover reasonable expenses for essentials while you wait for the bag — things like a change of clothes, toiletries, and medications. You must keep all receipts. Do not buy a new wardrobe; the airline will reject claims for luxury items or things you would have bought anyway. Stick to what you actually need to get through the next few days.

How to file a claim for lost luggage

Contact the airline in writing within 30 days of the flight. Most airlines accept claims through their website, by email, or by mail. Use the reference number from your airport report. Include a detailed list of what was in the bag, with the original purchase price or replacement cost for each item if you have it. Attach copies of receipts, photos, credit card statements, or any other proof of ownership and value.

The airline will investigate and respond within 30 to 45 days, though some take longer. If they find the bag, they will deliver it to you. If they cannot find it after 21 days, the bag is considered lost and you can claim its contents. If the airline denies your claim or offers less than you asked for, you can dispute it in writing and ask them to reconsider, or you can pursue the claim through small claims court if the amount is within your state's limit.

Keep copies of everything you send to the airline — your claim letter, receipts, photos, and the airline's responses. If you end up in court, you will need to show what you claimed and when. Some airlines settle disputes faster if you send a follow-up letter 60 days after your first claim, restating what you lost and what you are asking for.

Expenses while waiting for your bag

If your bag is delayed but eventually arrives, you can claim reasonable expenses for things you had to buy because you did not have your luggage. This includes a change of clothes, toiletries, medications, and other necessities. Keep every receipt. The airline will not reimburse you for entertainment, meals beyond what you would normally eat, or hotel upgrades.

If you are delayed overnight because of the lost bag, some airlines will cover a hotel room and meals under their delay policy, but this is separate from the lost luggage claim. Check your airline's policy on their website or ask at the counter. If the airline caused the delay through their own error, they may be more willing to cover these costs than if the bag was lost due to circumstances beyond their control.

For a bag delayed more than 12 hours on a domestic flight, keep receipts for essentials and submit them with your claim. The airline will review them and pay what they consider reasonable. If they deny a receipt, ask them why — sometimes a second submission with an explanation gets approved.

What to do if the airline refuses to pay

If the airline denies your claim or offers far less than you asked for, send a written response within 30 days. Explain why you believe your claim is valid, provide any additional evidence, and state the amount you are asking for. Some airlines will reconsider if you provide new information or correct an error in your original claim.

If the airline still refuses, you can file a complaint with the U.S. Department of Transportation if you are flying a U.S. carrier on a domestic or international flight. The DOT has a complaint form on its website. You can also take the airline to small claims court in your state if the amount is within your court's limit — most states allow claims up to $5,000 or $10,000. You do not need a lawyer for small claims court, and the filing fee is usually under $100.

Before you go to court, consider whether the airline's offer is close to what you are asking for. Court takes time and you may not recover more than what the airline already offered. If the airline owes you $500 and offered $300, it may not be worth the effort. If they offered $100 for a bag full of expensive items, it is worth pursuing.

How to avoid losing luggage in the first place

Pack a change of clothes, medications, and valuables in your carry-on bag instead of checked luggage. Airlines lose checked bags far more often than carry-on bags, and anything in your carry-on is your responsibility if it goes missing. Never pack irreplaceable items — photos, documents, jewelry with sentimental value — in checked luggage.

Use a distinctive bag or add a bright tag so your luggage is easier to spot on the carousel and less likely to be grabbed by mistake. Take a photo of your bag before you check it, including any identifying marks or damage. This photo is useful if you need to prove what your bag looked like when you handed it over.

Arrive at the airport early enough to check your bag with time to spare. Bags checked at the last minute are more likely to be mishandled or left behind. If you are connecting to another flight, ask the agent to tag your bag all the way to your final destination, not just to the connecting city.

Frequently Asked Questions

How long does it take to get money back for a lost bag?

If the airline finds your bag, they will deliver it to you, usually within 5 to 10 days. If the bag is lost and you file a claim, the airline has 30 to 45 days to respond. If they approve your claim, payment takes another 1 to 2 weeks. If you dispute the decision and go to small claims court, the process can take 2 to 6 months.

Can I claim the full replacement cost of items in my bag?

You can claim the original purchase price or current replacement cost, but the airline may dispute high-value items without receipts. Electronics, jewelry, and designer goods are scrutinized more closely. If you have credit card statements, store receipts, or photos showing you owned the items, your claim is stronger.

What if my bag arrives damaged instead of lost?

Report the damage to the airline's baggage office before you leave the airport. Take photos of the damage and the contents. File a claim for repair or replacement of damaged items using the same process as a lost bag claim. The airline's liability for damage is the same as for loss.

Do I need travel insurance to cover a lost bag?

No. The airline is legally required to compensate you for a lost bag up to the federal limit. Travel insurance can cover amounts above that limit or items the airline refuses to pay for, but it is not necessary for basic coverage. Check your homeowner's or renter's insurance — some policies cover luggage loss as well.

Can I claim a lost bag if I checked it at the gate instead of at the ticket counter?

Yes. The airline is responsible for your bag from the moment you hand it over, whether that is at the ticket counter, the gate, or the baggage drop. Report it missing using the same process and file a claim the same way.
