What Happens If an Airline Loses Your Luggage?
A suitcase that does not appear at baggage claim is usually considered delayed before it is officially declared lost. The airline must search for it, reimburse reasonable expenses during the delay, and compensate you if the bag cannot be recovered.
The airline must reimburse reasonable, verifiable expenses caused by the delay, subject to liability limits. Your baggage fee should also be refunded if the bag is declared lost or is not delivered within 12 hours after a domestic flight—or within 15 or 30 hours after an international flight, depending on the flight’s length.
What Should You Do When Your Luggage Does Not Arrive?
Do not leave the airport without reporting the missing bag. Go to the baggage-service desk for the airline that operated your final flight and file a mishandled-baggage report, even if an employee says the suitcase will arrive on the next flight. Keep the report number, baggage-claim tag, boarding pass, itinerary, and the contact information for the baggage office. If your trip involved multiple airlines, the final carrier will normally process the claim.
A missing suitcase is initially treated as delayed rather than permanently lost. The U.S. Department of Transportation says most airlines declare a bag lost between five and fourteen days after the flight, although the exact timeline varies. Stay in contact with the airline, update the delivery address if you move between hotels, and save screenshots from both the airline’s tracking system and any personal luggage tracker.
While the airline searches, it must compensate you for reasonable, verifiable, and actual incidental expenses caused by the delay. These can include necessities such as toiletries, basic clothing, or rental equipment required for the trip. Airlines cannot impose an arbitrary daily reimbursement limit, but purchases should remain reasonable for the circumstances. Ask what documentation the airline requires and retain an itemized receipt for everything you buy.
The baggage fee follows a separate rule. According to the U.S. Department of Transportation’s refund guidance, a checked bag becomes significantly delayed for refund purposes when it is not delivered within 12 hours of a domestic flight’s arrival. For an international flight, the threshold is 15 hours when the flight lasted 12 hours or less and 30 hours when it lasted more than 12 hours. You must file the baggage report, after which the fee should be refunded automatically once the applicable threshold is reached.
If the airline officially declares the bag lost, you can submit a detailed claim for the depreciated value of the suitcase and its contents. Current airline liability can be limited to $4,700 per passenger for domestic travel and 1,519 Special Drawing Rights—approximately $2,175 according to the Department of Transportation—for most international itineraries. These are maximums, not guaranteed payments. If the airline’s reimbursement does not cover the loss, your travel insurance or credit-card baggage protection may provide secondary coverage.
Delayed Luggage vs. Lost Luggage
A missing bag does not become officially lost the moment the carousel stops. The airline first searches for it as delayed baggage before beginning the permanent-loss claim process.
The Airline Is Still Searching
The airline tracks the suitcase and must reimburse reasonable, documented expenses caused by the delay, subject to applicable liability limits.
A Full Claim Is Required
Once the airline declares the bag lost, you submit an inventory of its contents and supporting records for compensation based on their depreciated value.
Which Baggage Rule Applies?
Your Bag Is Delayed
Buy only reasonable necessities, keep itemized receipts, and remain available to arrange delivery with the airline.
Your Bag Is Declared Lost
Submit the airline’s detailed claim form with an inventory, estimated values, receipts, photographs, and other available proof.
Your Bag Is Damaged
Report the damage before leaving the airport and photograph the suitcase, wheels, handles, straps, and affected contents.
Items Are Missing
Report pilfered contents immediately, even when the suitcase itself arrived. The airline may require a separate written claim.
What to Do When Your Bag Is Missing
- 01
Check the entire baggage area
Look near oversized baggage, neighboring carousels, and the airline’s baggage office before beginning the claim.
- 02
File a baggage report
Give the airline your baggage-tag number, contact information, delivery address, itinerary, and a clear description of the suitcase.
- 03
Get the report in writing
Keep the file number, report copy, follow-up contact details, baggage receipt, and the name of the airline representative.
- 04
Ask about delivery and expenses
Confirm where the bag will be delivered and how to submit receipts for reasonable purchases made while waiting.
A personal luggage tracker can help identify a bag’s approximate location, but it does not replace the airline’s required baggage report.

Airline Liability vs. Travel Insurance
The Airline’s Responsibility
The airline is the first source of reimbursement when it delays, loses, damages, or mishandles checked baggage.
Payments remain subject to proof, depreciation, excluded items, and domestic or international liability limits.
Insurance or Card Coverage
Travel insurance or a credit card may supplement the airline’s payment when the loss and items qualify.
The provider will usually require the airline’s baggage report, claim decision, receipts, and proof of any amount already reimbursed.
What Can Weaken a Baggage Claim
Leaving without filing a report
A verbal conversation is not enough. Insist on a written mishandled-baggage report and keep its reference number.
Throwing away the baggage receipt
The barcode receipt connects you to the checked suitcase and may be required for tracking and reimbursement.
Making unreasonable purchases
The airline must cover reasonable actual expenses, but expensive or unrelated purchases can be disputed.
Packing irreplaceable items in checked luggage
Medication, passports, keys, cash, jewelry, electronics, and sentimental objects are safest in a carry-on or personal item.
An airline cannot impose an arbitrary daily limit—such as only $50 per day—on reasonable expenses caused by delayed baggage. Reimbursement must reflect your actual, documented needs, subject to the overall liability limit.
The Essential Points
Report missing, damaged, or opened baggage before leaving the airport and keep a copy of the report.
Airlines must reimburse reasonable, verifiable expenses caused by delayed baggage, subject to liability limits.
A baggage-fee refund is separate from reimbursement for necessities and compensation for a permanently lost bag.
Travel insurance may supplement the airline’s payment, but it does not replace the initial claim against the airline.
Lost and Delayed Luggage FAQ
How long before delayed luggage is considered lost?
Airline policies vary, but most carriers declare a bag lost between five and fourteen days after the flight. Ask the airline when its permanent-loss claim process begins.
What can I buy while waiting for delayed luggage?
Reasonable necessities may include basic toiletries, clothing, and equipment required for the trip. What is reasonable depends on the destination, delay length, and purpose of travel.
Does the airline have to refund my checked-bag fee?
Yes, when the bag is declared lost or reaches the significant-delay threshold and you filed a mishandled-baggage report. Limited exceptions can apply.
How much will an airline pay for lost luggage?
For domestic travel, airline liability can currently be limited to $4,700 per passenger. Most international itineraries use a treaty limit of 1,519 Special Drawing Rights. Your payment depends on proven, depreciated value and may be below the maximum.
Does travel insurance cover lost luggage?
Many policies include baggage-loss or baggage-delay benefits. Coverage is often secondary, meaning you must first file with the airline and provide its settlement or denial.
Will an airline use data from my luggage tracker?
A tracker can provide useful location information, but the airline may rely on its own baggage system when tracing and routing the suitcase. Show the tracker location to the baggage representative without entering restricted airport areas yourself.
