Your bag didn't come out on the carousel. The airline hands you a claim number and tells you it will "probably turn up." Most of the time it does — but the money side of this is where travelers lose out, because airlines are only required to pay what you actually document, and there are hard deadlines that start ticking the moment you land.

Here's exactly what to do, in order, and what U.S. rules entitle you to.

Step 1: Report it before you leave the airport

This is the one step you cannot fix later. Go to the airline's baggage service office in the arrivals hall — not customer service, not the gate — and file a report in person before you exit. You'll get a file reference number (airlines call it a PIR, or Property Irregularity Report). Without it, later claims are routinely denied — and under the DOT's automatic bag-fee refund rule, the refund in Step 2 is only triggered once a mishandled-baggage report exists.

Give them a real address where you'll actually be for the next few days, not your home address if you're traveling. Take a photo of the printed report and the desk agent's name. If the office is closed because you landed at 1 a.m., call the airline's baggage line immediately and note the time — then follow up in writing the same day.

Note that if you connected between two airlines, you file with the last airline that carried you. They handle the claim even if the other carrier lost the bag.

Delayed vs. lost — the difference matters

A "delayed" bag is one the airline is still tracking. A "lost" bag is one the airline formally declares missing, and two different clocks decide when that happens. On an international itinerary, the Montreal Convention settles it: if the bag hasn't arrived 21 days after it should have, you may treat it as lost and claim for the contents. On a domestic U.S. flight there is no federal number at all — the carrier's contract of carriage sets it, and the published thresholds cluster between 5 and 30 days. Your compensation rights differ between delayed and lost, so pay attention to which label the airline is using, and ask them in writing to state the day the file converts.

Step 2: Get your checked bag fee back

This is the piece most travelers never claim. Under the U.S. Department of Transportation refund rule in force as of August 2026, airlines must automatically refund your checked bag fee if the bag isn't delivered within:

• 12 hours of gate arrival on a domestic flight
• 15 hours on an international flight of 12 hours or less
• 30 hours on an international flight longer than 12 hours

The refund is supposed to happen without you asking, and refunds to a credit card are due within 7 business days of becoming owed.

"Required to" and "actually do" are two different things. Check your card statement about a week after the trip. If the fee wasn't refunded, contact the airline citing the DOT baggage delay refund rule, and reference your file number. The rule and its current windows are published on the DOT's aviation consumer site — see DOT: Baggage. What you get back is the fee you actually paid, not a DOT-set flat amount: American, Delta and United have charged $35 online / $40 at the airport for a first checked bag since 2024, so a couple checking two bags each way is looking at $140 or more sitting in that refund.

Step 3: Buy what you need now — and keep every receipt

While your bag is delayed, airlines generally reimburse "reasonable and necessary" interim expenses: toiletries, underwear, a change of clothes, a phone charger, work clothes if you're on a business trip. What counts as reasonable is up to the airline, and they will push back on luxury purchases.

Practical rules that keep claims from getting cut:

• Buy modestly and buy locally — a mid-range replacement reads as necessary, a designer one doesn't.
• Keep itemized receipts, not just the credit card slip.
• Ask the baggage desk to state their per-day interim allowance and write down who told you and when. Carriers run to internal daily figures they don't publish, and a dated note of what an agent authorized is your leverage when the claim gets trimmed later.
• Don't wait 48 hours to buy essentials "in case it shows up" — that's not required, and it doesn't help your claim.

Airlines cannot cap your total compensation below the federal liability limit just by pointing to a daily interim allowance. Interim expenses count toward the overall limit, not against your rights.

Step 4: File the formal claim in writing

If the bag is declared lost, or if you have expenses to recover, submit the airline's written baggage claim form. Every major U.S. carrier has one online. Deadlines are short and strictly enforced, and which set applies depends on whether your itinerary was international or domestic. On international flights the Montreal Convention fixes them: 7 days from receiving the bag to complain about damage, 21 days to complain about delay, and 2 years to file suit. Miss the 7 or 21 days and the airline can refuse the claim outright. Domestic deadlines come from your carrier's contract of carriage — a legally binding document they must publish on their website — and typically run to reporting within 24 hours of arrival and a completed claim within 45 days.

Your claim should include:

• File reference number from the airport report
• Ticket number, flight numbers, and dates
• An itemized list of contents with approximate purchase dates and values
• Receipts or photos for anything of significant value
• Receipts for interim purchases

Be specific. "Clothing, $600" gets reduced. "Four shirts purchased 2025, approx. $45 each" gets paid. Airlines depreciate used items, so expect less than replacement cost on older clothing: a two-year-old $120 jacket documented with a receipt commonly settles nearer $60–$80, while the same jacket listed as "jacket, $120" with no proof of age or price is where adjusters cut hardest.

Step 5: Know the liability limit — and what's excluded

For a lost bag on a domestic U.S. flight, DOT sets the airline's minimum liability at $3,800 per passenger — the figure DOT raised from $3,500 in 2021, adjusted for inflation on a two-year cycle, so verify the current number before you value a large claim. International flights run on a different rule entirely: the Montreal Convention limit has been 1,519 Special Drawing Rights per passenger since December 28, 2024, roughly $2,000 depending on the SDR exchange rate on the day the airline pays. The limits are per passenger, not per bag. The domestic figure is published by DOT at transportation.gov/airconsumer.

More important than the ceiling is the exclusion list. Nearly every airline's contract of carriage excludes or sharply limits liability for electronics, jewelry, cash, keys, prescription medication, business documents, and fragile items — even when they're inside a checked bag. This is why the standard advice is to carry those on. If you already checked them and they're gone, you may still have a path through other coverage.

Where else your claim might get paid

Source	Typically covers	Watch out for
Airline	Bag fee refund, interim essentials, depreciated contents up to $3,800 domestic / 1,519 SDR international	7- and 21-day international complaint deadlines; broad exclusions
Credit card travel protection	Delayed and lost baggage, if you paid for the ticket with that card	Must file within the card's own window; often secondary to airline
Travel insurance	Contents beyond airline limits	Requires the airline's denial or settlement letter first
Homeowners or renters policy	Personal property away from home	Deductible may exceed the loss; claims can affect premiums

Order of operations: settle with the airline first, get their written settlement or denial, then take that document to your card issuer or insurer for the remainder. Most secondary coverage requires proof of what the airline paid.

Step 6: Escalate if the airline stalls

If weeks pass with no response or you get a lowball offer you can document is wrong, escalate in this order:

1. Reply to the claim in writing, restating the file number and attaching the receipts again.
2. Ask specifically which provision of the contract of carriage they're relying on to reduce or deny the claim.
3. File a complaint with the DOT Aviation Consumer Protection Division at transportation.gov/airconsumer/complain. Airlines are required to respond to DOT-forwarded complaints, and this frequently unsticks a stalled file.

Keep everything in email or the airline's web form so you have a timestamped record. Phone calls with no written follow-up are worth very little when a claim goes sideways.

FAQ

How long does an airline have to find my bag before it counts as lost?

It depends on where you flew. International itineraries are governed by the Montreal Convention: 21 days after the bag should have arrived, you can treat it as lost. Domestic flights have no federal number — each airline sets its own threshold in its contract of carriage, and published thresholds run from about 5 days to 30. Until they declare it lost, they'll treat it as delayed, and you can still claim interim expenses during that period.

Can I claim if my bag arrived but was damaged or emptied?

Yes, but the deadline is much tighter than for a lost bag. On an international flight you have exactly 7 days from the day you received the bag to put the complaint in writing. Domestic carriers set their own in the contract of carriage, commonly 24 hours to report the damage and 45 days to complete the claim. Report damage or missing contents before leaving the airport if you notice it there, and photograph the bag and the tag immediately. Airlines commonly exclude ordinary wear, minor scuffs, and protruding parts like wheels and handles.

Does trip insurance or my credit card make the airline claim unnecessary?

No. Nearly all card and travel-insurance baggage benefits are secondary, meaning they pay only what the airline didn't. Skipping the airline claim usually means the other coverage denies you too. File both, in that order.

Where the call actually splits

If your bag came back within a day or two, the only money on the table is the checked bag fee, and the DOT rule refunds it automatically once delivery passes 12 hours domestic, 15 hours on a short international flight, or 30 hours on one over 12 hours. Do nothing except check the statement about a week out — at $35 online or $40 at the airport, a couple checking two bags each way is $140 that quietly fails to appear.

If you flew internationally, treat the clock as the whole game: 7 days to complain about damage, 21 days about delay. Those two deadlines let the airline refuse outright, so file in writing with the file reference before your receipts and itemized list are complete, and supplement after.

If the contents are ordinary clothing, the airline claim alone is the right stopping point. Depreciation is the real cost, not the ceiling — a documented two-year-old $120 jacket settles near $60–$80, and undocumented it settles lower, so itemizing beats escalating.

If the loss involves electronics or jewelry, or exceeds $3,800 domestic / 1,519 SDR internationally, you need the airline's written settlement or denial first, then the card issuer. Going to homeowners is the worse route whenever the remainder is near your deductible, since the claim can move your premium for a payout that barely clears it.
