An airline can lose your checked bag and still owe more than an apology. Depending on the trip, you may recover the checked-bag fee, reasonable essentials bought during the delay, and the documented value of property that never returns. There isn't an automatic flat payout.
Start with the itinerary. The airline's home country doesn't choose the rule by itself. Domestic U.S. baggage limits, the Montreal Convention, and EU261 address different claims.
Start with the rule that fits the trip
First, sort the journey into the right category.
| Travel situation | Rule that usually controls | Practical effect |
|---|---|---|
| U.S. domestic flight | U.S. Department of Transportation baggage rules, including 14 CFR Part 254 | For covered domestic carriage, the carrier may owe actual, provable baggage loss up to the applicable liability limit. |
| International itinerary | Montreal Convention, when its conditions apply | The carrier may owe proven loss, damage, or delay damages, subject to treaty limits and written-complaint windows. |
| EU-covered flight disruption | EU261 for qualifying cancellations, denied boarding, or long delays | A qualifying disruption can create separate flight-rights claims. EU261 is not the usual rule for valuing missing contents. |
| Flight to, from, or within the United States | 14 CFR 260.5 for qualifying checked-bag fee refunds | A covered carrier may have to refund the checked-bag fee when a bag is lost or significantly delayed. |
A single journey can touch more than one row. A qualifying EU flight disruption, for example, can raise an EU261 issue while a baggage claim follows the Montreal Convention.
Codeshares add a practical wrinkle. Begin with the airline that took the baggage report, then check the itinerary and contract of carriage to see where the formal claim belongs.
Delta, United, American, and other airlines use different forms, reporting windows, and document requests. Those procedures don't replace federal or treaty rights, but they can affect whether your file reaches the right claims team.
What the airline may owe
Think in two steps: prove the loss, then check the ceiling.
For covered domestic U.S. carriage, the liability ceiling can reach $4,700 per passenger. That figure isn't a preset award.
International baggage claims use a current limit of 1,519 Special Drawing Rights per passenger under the Montreal Convention. The dollar value of an SDR changes. The limit is still only a ceiling.
| Type of loss | What you may recover | Evidence that helps |
|---|---|---|
| Checked-bag fee | The fee paid when a qualifying refund applies | Baggage receipt and mishandled-bag report |
| Delayed-bag essentials | Reasonable, necessary purchases made during the delay | Itemized receipts and purchase dates |
| Lost contents | Actual, provable value, subject to the applicable limit and exclusions | Inventory, receipts, photos, and purchase details |
| Damaged bag or contents | Repair cost or reasonable value of the damage | Photos, repair estimate, and proof of condition |
A carrier may consider age, condition, and ordinary depreciation. Cash, luxury goods, fragile property, and other restricted items may have separate exclusions or contract limits.
The checked-bag fee has its own rule
For a qualifying flight to, from, or within the United States, 14 CFR 260.5 requires a covered carrier to refund a checked-bag fee after the passenger reports a lost or significantly delayed bag and the regulatory conditions are met. In qualifying cases, the regulation provides for an automatic refund.
The threshold for a domestic flight is 12 hours after gate arrival. For an international flight, it is generally 15 hours when the flight lasts 12 hours or less, or 30 hours when it lasts longer.
The refund must be at least the fee paid. It doesn't pay for clothes, toiletries, electronics, or other contents.
Some exceptions matter. They include failing to collect and recheck the bag at the first U.S. entry point when Customs and Border Protection requires it, or voluntarily agreeing to travel without the bag on that same flight.
Turns out, a fee refund and a contents claim are separate parts of the file. Even if the refund should be automatic, list it separately when you write.
Deadlines can decide the claim
Report the problem right away. Waiting for the search to end can cost evidence, even before a formal treaty deadline arrives.
| Problem | International written-complaint window | Practical move |
|---|---|---|
| Damaged baggage | Generally within 7 days after receiving the bag | Photograph the damage before repair and send written notice |
| Delayed baggage | Generally within 21 days after the bag is made available | File the airport report, then submit a separate written claim |
| Bag not delivered | After 21 days, the passenger can generally pursue it as lost under the Montreal Convention | Ask the airline to convert the tracing file into a lost-bag claim |
| Domestic U.S. baggage problem | Carrier terms and claim procedures can affect the reporting window | Report at once and follow the airline's current instructions |
Thing is, 21 days is not a reason to wait. It is a treaty threshold for late or undelivered international baggage, not a suggested reporting date.
A Property Irregularity Report, or PIR, creates the airport record. Send a separate written claim too, so the date, loss, and amount requested are clear.
An international claim can also face a two-year court limit under the Montreal Convention. The deadline depends on treaty coverage and the type of legal action, so check the ticket contract and applicable law before relying on it.
File the claim in this order
Use this order while names, dates, and receipts are still easy to find.
-
Report the bag before leaving the airport. Ask for a PIR number and confirm that the bag tag is correct. If the desk is closed, use the airline's website or app and save a screenshot.
-
Create one travel file. Keep the boarding pass, itinerary, baggage tag, PIR, delivery messages, and every email or chat with the carrier together.
-
Spend narrowly. Buy only what you genuinely need during the delay. Keep itemized receipts and record the purchase date for each expense.
-
Send the written claim. State whether the bag was delayed, lost, or damaged. Include the flight, route, bag tag, PIR number, delivery date if applicable, and amount requested.
-
Separate the categories. Show the checked-bag fee, delayed essentials, damaged property, and missing contents on separate lines. Tell the airline and insurer about the other claim, and don't request payment twice for the same expense.
-
Follow up in writing. Ask for a delivery update, valuation explanation, or specific reason for a denial. Once the applicable lost-bag threshold passes, request a lost-baggage settlement instead of another vague tracing update.
Search tools can show activity. They don't replace a written claim.
Make the evidence easy to check
A reviewer can handle a messy travel day. An unexplained total is harder to assess.
| Record | Why it matters |
|---|---|
| PIR and bag tag | Connects the bag to the flight and incident |
| Boarding pass and itinerary | Shows the journey, dates, and carriers |
| Itemized contents list | Identifies each missing or damaged item |
| Receipts or reasonable purchase records | Supports value, age, and ownership |
| Essential-expense receipts | Shows what you bought during the delay |
| Photos and repair estimates | Helps establish damage and pre-repair condition |
| Emails, chats, and denial letters | Records promises, offers, and reasons |
If you lack a receipt, provide the brand, model, approximate purchase date, original price, and current replacement or used value. Honest estimates beat inflated totals.
Keep the airline's messages too. A delivery estimate, a promise to call, or a change in status may matter later, even when saving every message feels repetitive.
Montreal Convention and EU261 are not interchangeable
International baggage disputes often turn on the Montreal Convention. The treaty covers carrier liability for baggage that is lost, damaged, or delayed, and sets limits plus written-complaint deadlines.
EU261 can show up in the same dispute. The European Union's passenger-rights guidance treats lost, damaged, or delayed baggage as an airline-liability issue, while its fixed flight compensation addresses qualifying cancellations, denied boarding, and long delays.
A missing bag alone usually doesn't create an automatic EU261 payment of 250 to 600 euros. Claim the actual baggage loss under the applicable baggage rules, then assess any separate flight disruption on its own facts.
IATA is an industry association, not a court for passenger claims. WorldTracer and an airline app may help document the search history, but a tracking entry doesn't set the payout or replace a written claim.
If the airline denies the claim
Ask for the reason in writing. The dispute may concern responsibility, the value of the contents, the timing of your notice, or the necessity of an expense.
| Next route | What it can do |
|---|---|
| Airline review | Correct missing documents, challenge the valuation, or clarify the policy used |
| DOT Aviation Consumer Protection complaint | Brings a U.S.-covered airline complaint to the regulator's attention and may prompt a response |
| Travel insurance claim | May cover losses the airline does not, subject to the policy's limits, deductible, and deadlines |
| Court or arbitration | May be available under the contract and applicable law; check filing deadlines first |
To be honest, a DOT complaint doesn't guarantee a check. It is a regulatory complaint, not a private court judgment.
Arbitration isn't automatically handled by IATA or the American Arbitration Association. Read the airline's contract of carriage to see whether arbitration is required, optional, or unavailable for the dispute.

Insurance, credit cards, and chargebacks
Travel insurance may cover baggage delay or loss, but the policy controls. Check the deductible and per-item limit first. Then review exclusions, the notice deadline, and any requirement to pursue the airline before the insurer pays.
Credit-card baggage benefits have their own eligibility rules. The card issuer may require that you paid for the fare with that card, along with the airline's denial or settlement decision.
A chargeback is a separate billing process. The airline provided transportation, so a credit-card dispute isn't a guaranteed substitute for a baggage claim. A debit-card or credit-card dispute may not recover the suitcase's value.
Questions readers usually ask
Does the airline automatically pay the full $4,700 domestic limit?
No. The $4,700 figure is a liability ceiling, not a standard settlement. You still need to prove the actual loss, and exclusions or valuation rules may apply.
Is 21 days the deadline to report every lost bag?
No. Notify the airline immediately. For international carriage, 21 days mainly matters for delayed-baggage complaints and the point at which an undelivered bag can generally be pursued as lost.
Does EU261 pay for lost luggage?
Usually not as fixed flight-disruption compensation. Baggage loss and delay generally fall under the applicable airline-liability rules, often the Montreal Convention.
What if I left the airport without a PIR?
Contact the airline through its website, app, phone line, or email as soon as possible. Explain why no airport report was available, save proof of the contact, and preserve the bag tag and travel documents.
Put the PIR, bag tag, itinerary, receipts, photographs, and itemized contents list in one folder now. Then send the written claim before the next deadline passes.
