Lost Baggage: How to File a Claim and Get Paid (Step by Step)

If your checked bag didn't come off the carousel, go straight to the airline's baggage service office in the arrivals area before you leave the airport and file a written report. You'll get a file reference number (called a PIR — Property Irregularity Report). Do this the same day. Filing on the spot is the single most important step, because most airlines require you to report a mishandled bag within 4 hours to 24 hours of arrival, and delaying gives them an easy reason to deny your claim later.

Here's the good news: US Department of Transportation rules put real money on the table. Airlines are liable for up to $3,800 per passenger for lost, damaged, or delayed checked baggage on domestic flights, and they must reimburse you for reasonable expenses while your bag is delayed. Below is exactly how to file, what to say, and how to actually get paid.

Step 1: File the report at the airport (before you leave)

Find the baggage service office — it's near the carousels, usually staffed by the airline or a ground-handling contractor. Report the bag missing and get these three things:

• A written PIR / file reference number. Photograph it. Every future conversation starts with this number.
• The name and phone number of the baggage office. Ask specifically how you'll be updated (text, email, app).
• A description on file: bag brand, color, size, any tags, and the contents. Have your bag claim tag (the sticker they gave you at check-in) ready.

If the office is closed or the line is impossible, file through the airline's app or website the same day and note the time. Do not walk out assuming the bag will "just show up" without a report on record — an unreported bag is a much harder claim.

Delayed vs. lost matters. A bag is officially "delayed" while the airline is still looking for it, and "lost" once they declare it can't be found — usually after 5 to 14 days depending on the airline (American and United typically use around 5 days, Delta similar). Your reimbursement path changes once it's declared lost.

Step 2: While your bag is delayed — get reimbursed for essentials

You do not have to sit and wait empty-handed. DOT requires airlines to compensate you for reasonable, verifiable expenses you incur because your bag is delayed. That means clothing, toiletries, phone chargers, and other necessities you need to get by.

What "reasonable" means in practice:

• Keep every receipt. No receipt, no reimbursement.
• Buy what you actually need now — a few changes of clothes, toiletries, contact lens supplies, work-appropriate clothing if you're traveling for business. Don't buy a $600 designer coat and expect full payback.
• Airlines can't cap this at an arbitrary low number. Some agents will tell you "$50 a day." That's the airline's internal comfort zone, not the law. The legal ceiling is the $3,800 total liability limit; reasonable interim expenses count against it.

Airline-specific interim allowances vary. Delta, United, and American all reimburse necessities for delayed bags but expect itemized receipts and will scrutinize anything that looks like a shopping spree. Submit these expenses through the same claim file.

What you can't claim

Airlines exclude a long list of items from liability even within that $3,800 cap: cash, jewelry, electronics, cameras, important documents, medication, and other valuables. That's why you never check those. If your laptop was in the lost bag, the airline will very likely deny it under its contract of carriage.

Step 3: Track the bag and keep pressure on

Most bags turn up within a couple of days. Use every tracking tool:

• The airline app — enter your file reference number to see status.
• WorldTracer — the global system most US airlines use; the airline can give you a WorldTracer file number.
• An AirTag or Tile — if you had one in the bag, you often know where it is before the airline does. Tell the baggage office the exact location; it genuinely speeds things up.

Call the baggage office every day and reference your file number. When the bag is found, most airlines will deliver it to your address at no charge. Confirm the delivery window and get it in writing.

Step 4: When the bag is officially lost — file the full claim

Once the airline declares the bag lost (or if it's clearly gone), you move from "interim expenses" to a full loss claim for the value of the bag and its contents, up to $3,800 on a domestic flight.

Here's what a strong claim includes:

1. Your PIR / file reference number and original bag claim tag.
2. An itemized inventory of everything in the bag with estimated values. Be honest and specific — "Levi's 511 jeans, ~$60" beats "some pants."
3. Proof of value where you have it: receipts, credit card statements, order confirmations, even photos of you wearing the items. You won't have receipts for everything; do your best.
4. The value of the suitcase itself.
5. Your boarding pass and ticket receipt to prove you flew.

Submit through the airline's baggage claim portal (all major carriers have online forms). Airlines apply depreciation to used items — a two-year-old jacket won't reimburse at full retail. Push back if their depreciation seems aggressive, and cite the $3,800 limit as your ceiling, not their lowball offer.

Step 5: Get baggage fees refunded too

If you paid to check the bag that got lost, you're entitled to a refund of that checked-bag fee — DOT made this explicit. Ask for it specifically; airlines rarely refund it automatically. For delayed bags, DOT's 2024 refund rule requires airlines to refund the checked-bag fee if the bag isn't delivered within 12 hours of a domestic flight's arrival (or 15–30 hours for international), provided you filed a mishandling report. This is separate from your loss claim — make sure you claim both.

If you're also dealing with a canceled or delayed flight on the same trip, know the difference between baggage rules and flight rules. Baggage has that $3,800 liability cap, but the US has no mandatory delay-compensation law like the EU's — see Flight Delay Compensation in the US: What You're Actually Owed so you don't chase money that doesn't exist. If your flight was canceled, our Flight Cancelled? Here's Exactly What to Do guide covers your refund and rebooking rights.

Claim timelines and dollar amounts at a glance

If the airline stalls or lowballs you

Airlines routinely open with an offer well below what your stuff was worth. You don't have to accept it. Options:

• Counter in writing with your itemized list and any proof of value. Reference the $3,800 cap.
• Escalate to the DOT. File a complaint at transportation.gov/airconsumer. The airline must acknowledge it and respond, and a DOT complaint often unsticks a stalled claim fast.
• Check your credit card and travel insurance. Many travel rewards cards include baggage delay and lost-luggage coverage that stacks on top of the airline's payout — often $500–$3,000. File that claim in parallel.
• Homeowners or renters insurance may cover off-premises theft/loss of belongings, sometimes for the valuables the airline won't touch.

Keep everything in writing. A paper trail with your file number, receipts, and dates is what turns a "no" into a check.

Frequently Asked Questions

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

Interim expense reimbursements often come within a few weeks. Full loss claims typically take 4–8 weeks after you submit a complete claim, sometimes longer if you're negotiating value. Submitting a clean, itemized claim with proof up front is the fastest route.

What if the airline only offers me $50 a day for a delayed bag?

That's an internal guideline, not the law. DOT requires reimbursement of reasonable expenses, and there's no legal $50 daily cap — the ceiling is the $3,800 total liability. Submit real receipts for genuine necessities and push back if they refuse legitimate costs.

Can I claim for valuables like a laptop or jewelry that were in the bag?

Usually no. Airlines exclude electronics, jewelry, cash, and other valuables from baggage liability in their contract of carriage. Always carry those items on. Your credit card benefits or homeowners/renters insurance may cover them instead.

Does the $3,800 limit apply to international flights?

No. International trips fall under the Montreal Convention, which caps liability at roughly $1,800 per passenger (about 1,288 SDR). You must file a written claim within 21 days of when the bag should have arrived, so don't wait.
