The airline is responsible for finding your bag or paying you for what was inside
When an airline loses your luggage, the airline becomes legally responsible for the contents. The airline must either locate and return your bag, or compensate you for the items that were lost. The amount you receive depends on the airline's rules, the route you flew, and what you can prove you had in the bag.
The process starts the moment you report the loss at the airport. You will file a report with the airline's baggage desk before you leave the terminal — do not wait. The airline then has a set window to search for your bag, usually 21 days for domestic flights in the United States. If the bag does not turn up, the airline moves to compensation.
Key Takeaways
- Report a lost bag to the airline's baggage desk before leaving the airport, and ask for a written incident report with a reference number.
- Domestic flights in the US are capped at $3,800 per passenger for lost luggage, while international flights follow different rules depending on which country you flew to.
- The airline will search for your bag for up to 21 days; if it is not found, you can file a claim for compensation.
- Keep receipts, photos, or credit card statements that show you owned the items in your bag, because the airline will ask for proof of value.
- If the airline denies your claim or offers too little, you can dispute it through the airline's appeals process or file a complaint with the Department of Transportation.
What to do at the airport when your bag does not arrive
Go directly to the airline's baggage office before you leave the terminal. Tell them your bag did not arrive and describe it — color, size, any distinctive marks. The agent will ask for your baggage tag number, which is on your boarding pass or receipt. Write down the reference number they give you; you will need it to track your claim.
Ask the agent for a written incident report. Some airlines call this a Property Irregularity Report (PIR). This document is your proof that you reported the loss on the day it happened, and it strengthens any claim you file later. Take a photo of the report or ask for a copy before you leave the desk.
If your bag is delayed but not lost, the airline may offer to deliver it to you once it arrives. You can also ask the airline to reimburse you for essential items you need to buy while you wait — toiletries, a change of clothes, phone chargers. Keep all receipts. Some airlines have a daily limit for these expenses, often $100 to $200, and you will need to submit receipts to be reimbursed.
How much the airline will pay you
The amount depends on whether your flight was domestic or international. For domestic flights within the United States, the airline's liability is capped at $3,800 per passenger under federal law. This is the maximum, not a may provide — you will receive less if you cannot prove the items in your bag were worth more.
For international flights, the rules change based on which country you flew to. Most international flights are covered by a treaty called the Montreal Convention, which sets a limit of about 1,350 Special Drawing Rights (SDR) — roughly $1,800 to $1,900 in US dollars, though the exact amount shifts with currency exchange rates. Some airlines may have lower limits in their own rules, so check your airline's contract of carriage on their website.
The airline will not pay you the full amount unless you can show what was in the bag and what it cost. This is where receipts matter. If you bought a suitcase full of new clothes for a trip, bring the store receipts or credit card statements showing the purchases. If the items were used, the airline may deduct for depreciation — a two-year-old jacket is worth less than a new one.
Filing a claim after the search period ends
Once 21 days have passed and the airline has not found your bag, you can file a formal claim. Contact the airline's baggage department and ask for a claim form. Some airlines let you file online through their website; others require a paper form mailed to a specific address. The airline will tell you which method they use.
On the claim form, list every item that was in your bag and its value. Be specific: do not write "clothing" — write "two pairs of jeans ($60 each), one wool sweater ($85), five t-shirts ($15 each)." Attach copies of receipts, credit card statements, or photos that show you owned these items and what they cost. If you do not have receipts for everything, explain what you remember and provide what documentation you can.
The airline will review your claim and either approve it, deny it, or offer a lower amount than you requested. They have different timelines depending on the airline, but most respond within 30 to 60 days. If they approve it, they will send you a check or credit to your original payment method.
What to do if the airline denies your claim or offers too little
If the airline rejects your claim or the amount is too low, you have options. First, ask the airline to reconsider. Send a letter to their claims department explaining why you believe your claim is valid. Include any new documentation you have found — a receipt you located, a photo of the item, a credit card statement you overlooked. Airlines sometimes reverse a denial on appeal.
If the airline will not budge, you can file a complaint with the Department of Transportation (DOT). The DOT has a consumer complaint database and will investigate if you believe the airline violated federal rules. You can file online at the DOT's website or by mail. The DOT cannot force the airline to pay you, but a complaint on record can pressure the airline to settle, and it helps the DOT track patterns of poor service.
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. Small claims court is faster and cheaper than hiring a lawyer, and you do not need an attorney to file. Bring your incident report, receipts, photos, and any written correspondence with the airline.
How to protect yourself before your next flight
Take a photo of your packed suitcase before you close it. This creates a record of what was inside and its condition. Keep receipts for expensive items you pack — electronics, jewelry, designer clothing. If you are traveling with new purchases, keep the store receipt or credit card statement in your carry-on bag, not in your checked luggage.
Use a distinctive luggage tag or mark your suitcase in an obvious way so you can identify it if it shows up later. Many lost bags are eventually found but go unclaimed because the owner cannot prove it is theirs. A bright ribbon, a sticker, or a custom tag makes your bag straightforward to spot.
Consider purchasing baggage insurance if you are traveling with high-value items. Travel insurance policies often include baggage coverage that pays out faster than filing a claim with the airline, and the payout limit is sometimes higher than the airline's legal cap. Read the policy carefully to understand what is covered and what is not.
Frequently Asked Questions
Can the airline refuse to pay because I did not have receipts for everything?
No, but it makes your claim harder to prove. If you have no receipt for an item, the airline may offer you a lower amount based on what they think a similar item costs. You can dispute that offer, but you will need other evidence — a credit card statement, a photo, a witness who saw you pack it. Bring whatever documentation you have.
What if my bag arrives after I have already filed a claim?
Tell the airline when ready. If your bag arrives damaged or with items missing, you can still file a claim for the damage or missing contents. If it arrives in good condition with everything inside, you may need to withdraw your original claim or return any payment the airline already sent you.
Does travel insurance cover lost luggage?
Some policies do, but not all. Travel insurance that includes baggage coverage will pay you directly without requiring you to file a claim with the airline first. Read your policy's fine print to see what the baggage limit is and whether it covers lost bags, delayed bags, or both. Baggage insurance is separate from travel insurance and can be purchased on its own.
How long do I have to file a claim with the airline?
Most airlines require you to file a claim within 30 days of the flight, though some allow up to 90 days. Check your airline's website or your incident report for the exact important date. Missing the important date can disqualify you, so do not wait.
What if the airline says my bag is "delayed" instead of "lost"?
A delayed bag is one the airline believes will arrive eventually. The airline will search for it and try to deliver it to you. If it arrives within 21 days, the case is closed. If it does not arrive after 21 days, it becomes a lost bag and you can file a claim for compensation.
