If your checked bag is missing, report it before you leave the airport. Ask for the file number, keep the bag tag, and save receipts for basic items you had to buy.
That first report matters, but it isn't the whole claim. The airline may reimburse reasonable necessities during a delay, while a lost-bag payment generally depends on documented financial loss, the itinerary, and the rule that applies.
Stress and inconvenience don't create an automatic payment by themselves. The practical upside is limited: you may pack lighter next time, and receipts for basic essentials might help during a delay.
Start by identifying what happened
First identify the bag's status. That label changes the next step.
| Status | Meaning | Next move |
|---|---|---|
| Delayed | The bag did not arrive with you but may still be located. | Report it immediately and record necessary purchases. |
| Lost | The airline declares the bag missing, or the applicable waiting period expires. | Prepare an inventory and submit the formal claim. |
| Damaged | The bag arrived, but the case or its contents were harmed. | Photograph the problem and report it promptly. |
Turns out, the airport report is only the opening record. For international carriage covered by the Montreal Convention, baggage not delivered within 21 days is generally treated as lost, although the carrier can declare it lost sooner.
Domestic U.S. carriers use their own published process for moving a case from delayed to lost. Start gathering proof now.
The costs are much clearer than the benefits
Most baggage claims turn on documented financial loss. During a delay, reasonable toiletries, underwear, or practical clothing may qualify if the purchases are connected to the delay.
The other side is less tidy. You may pay for replacements, extra transport, missed plans, and the time needed to complete the claim.
Stress is real, but it usually isn't a separate automatic payment. A carrier may reimburse necessities; it won't simply pay because the experience was frustrating.
Which baggage rule applies in the United States?
The number below is a ceiling, not a promised check. You still have to show what was lost and why the amount is reasonable.
For 2026, the main limits are:
| Trip type | Main rule | Maximum baggage liability | What the amount covers |
|---|---|---|---|
| Covered domestic U.S. transportation | 14 CFR Part 254 | Up to US$4,700 per passenger | Proven loss, damage, or delay, subject to the airline's applicable terms |
| International carriage covered by the Montreal Convention | Montreal Convention | 1,519 Special Drawing Rights, roughly US$2,000 | Proven baggage loss, damage, or delay |
The international figure is stated in Special Drawing Rights, not dollars. Its U.S. dollar value changes with exchange rates.
Older pages may still quote US$3,800 for domestic baggage. Check the publication date before relying on that number.
The carrier generally looks at your actual financial loss. Age, condition, and purchase evidence can affect the value assigned to an item. Luxury items without proof and replacement upgrades are hard to justify.
EU261 is separate. When its conditions are met, it can provide fixed compensation for certain flight delays, cancellations, or denied boarding. It is not the main baggage-loss rule and does not automatically pay for missing contents.
Deadlines can decide a good claim
The conversation at the baggage carousel and the written complaint are not always the same step.
| Problem | Montreal timing | What to remember |
|---|---|---|
| Damaged baggage | Written notice within 7 days after receiving the bag | Report visible damage at the airport, then follow up in writing. |
| Delayed baggage | Written notice within 21 days after the bag is made available to you | Keep receipts for reasonable necessities bought during the delay. |
| Lost baggage | After 21 days without delivery, or sooner if the airline declares it lost | Send the contents inventory promptly rather than waiting indefinitely. |
| Court action under Montreal | Generally within 2 years | This is separate from the airline's claim process. |
For a domestic U.S. trip, report the problem immediately and read the carrier's current baggage terms. The timing for an initial report or a formal claim can differ.
A Property Irregularity Report, usually called a PIR, records what happened at the airport. It may not replace a separate written complaint or online claim form. Use both when the airline provides both options.
Create a paper trail from the start
Make the record while the details are fresh. Then keep the file moving.
-
Report the missing bag before leaving. Visit the airline's baggage service desk. If it is closed, use the carrier's app or phone line and write down when you made contact.
-
Get the case number in writing. Check the bag tag number, delivery address, phone number, and email address. Ask where receipts should go.
-
Keep the travel record together. Save the boarding pass, itinerary, baggage receipt, bag-tag sticker, and tracking screenshots.
-
Write an inventory. List each missing item, its approximate purchase date, condition, and replacement cost. Photos, serial numbers, and older receipts help with expensive items.
-
Buy only sensible essentials. Basic toiletries, underwear, and practical clothing are easier to support than designer replacements or a complete new wardrobe. Keep itemized receipts.
-
Send the formal claim. Include the itinerary, bag tag, airport report, inventory, receipts, delivery details, and a short timeline. On a connecting itinerary, ask which operating carrier or claims channel should receive it.
-
Update the file as the bag moves. Inspect the bag as soon as it arrives. For international carriage, report damage in writing within 7 days of receiving it. If it is still missing after 21 days, submit the lost-baggage inventory instead of waiting for another update.
If the airline rejects the claim, ask for the reason in writing. You can then contact its customer-relations team and file a complaint using the U.S. Department of Transportation's baggage guidance and consumer protection office.
Evidence makes the claim easier to check
Good evidence answers three questions: what happened, what you owned, and what it cost.
| Evidence | Why it matters |
|---|---|
| Baggage receipt and tag number | Connects the bag to your itinerary. |
| Boarding pass or ticket record | Shows the journey and relevant carrier. |
| Airport report and case number | Confirms that you reported the problem. |
| Receipts for essentials | Shows the expense caused by the delay. |
| Inventory with photos or serial numbers | Supports ownership, condition, and value. |
| Airline emails and delivery notices | Establishes when the bag was delayed or returned. |
Reasonable usually means a few days of basics, not a designer shopping spree. Airlines often challenge purchases that look like upgrades.
To be honest, travelers often remember the expensive contents and forget the small proof - the boarding pass, bag tag, delivery notice, and date the airline said the bag was available. Those details look minor. They can determine whether the timeline is easy to verify.
Insurance and card benefits cover different gaps
Travel insurance and credit-card baggage benefits sit alongside the airline's liability. They may cover a shortfall, but each policy can have its own limits, deductible, exclusions, proof requirements, and order of payment.
Many policies separate baggage delay from baggage loss. A card benefit may require you to have paid for the fare with that card, and it may pay only after another source of recovery. Read the certificate, not just the benefits summary.
Insurance may matter more if you carry expensive equipment, travel with several bags, or can't easily cover an emergency replacement bill. For an ordinary bag of clothing, compare the premium, deductible, and sublimits first.
Online reviews cannot extend a legal deadline or guarantee a payout. The policy wording controls.
Delta and American: compare the process, not the headline
Delta and American don't have different federal baggage ceilings for the same type of trip. A covered domestic claim is generally measured against the domestic rule, while qualifying international carriage is measured under the Montreal Convention.
Thing is, an app's design or an airline's mishandling rate does not decide whether your claim succeeds. Your evidence and the current written process matter more.
| What to compare | Why it matters |
|---|---|
| Initial reporting window | Missing a carrier deadline can complicate a domestic claim. |
| Interim-expense rules | Shows which necessities and receipts the airline considers. |
| Claim submission method | Tells you where to upload the inventory and documents. |
| Tracking and delivery updates | Helps establish the delay timeline. |
| Escalation route | Gives you a next step if the first claim is denied or ignored. |
Don't rely on an old blog's promised daily allowance or claim that one airline always pays faster. Check the carrier's baggage page and the terms attached to your itinerary, then save a copy while traveling.
Reduce the damage before you check a bag
Checked luggage isn't risk-free. A few packing choices can make a short delay less disruptive and a later claim easier.
- [ ] Put medication, identification, keys, electronics, valuables, and one change of clothes in your carry-on.
- [ ] Remove old baggage stickers and add contact details inside and outside the bag.
- [ ] Photograph the bag, its contents, and serial numbers before checking it.
- [ ] Use a tracker as a location aid, not as a substitute for the airline's bag tag.
- [ ] Choose fewer connections when the price and schedule make that practical.
- [ ] Keep the baggage receipt until the trip is over.

Common questions
Is a delayed bag automatically lost after 21 days?
Not under every rule. For international carriage covered by the Montreal Convention, a bag not delivered within 21 days is generally treated as lost. Domestic U.S. carriers may use different internal procedures, so follow the airline's written instructions.
Does the airport report count as the final claim?
Not necessarily. The report creates a record, but the airline may still require a separate written claim, contents list, and receipts. Submit that formal claim before the applicable deadline.
Can I buy anything while my bag is missing?
Buy reasonable necessities tied to the delay. Basic toiletries and clothing are easier to support than luxury goods, upgrades, or unrelated purchases. Keep every receipt.
Does EU261 pay compensation for lost baggage?
Usually not. EU261 concerns certain flight disruptions, while baggage loss, damage, and delay are generally handled under the Montreal Convention when it applies.
If your bag is missing today
If you're still at the airport, visit the baggage service desk before leaving. If you've already gone, open the airline's baggage case now and attach the airport report, bag tag, itinerary, inventory, and receipts.
Put the applicable 7-day, 21-day, or carrier-specific date on your calendar. Keep the file number with your travel records.
