Delayed baggage compensation: how much airlines must pay

Who actually owes you money when a bag is late

The airline that operated the flight where your bag went missing is liable — not the travel agency, not the credit card, not the airport. On U.S. domestic itineraries the U.S. Department of Transportation's Part 254 rules apply: airlines must reimburse passengers for reasonable, actual, incidental expenses caused by a delayed bag, up to a per-passenger liability cap the DOT adjusts for inflation (currently around $3,800 per passenger).

On international itineraries the Montreal Convention takes over. It sets a strict-liability regime up to 1,288 Special Drawing Rights per passenger (roughly $1,700 at recent exchange rates) for delay, damage, or loss. Codeshares can complicate this: the operating carrier is usually on the hook, but you can also claim from the contracting carrier that sold the ticket.

Credit card travel insurance and standalone travel policies often stack on top — they pay after the airline pays, so file with the airline first even if you plan to claim elsewhere.

Delayed vs. lost vs. damaged — the deadlines differ

Airlines distinguish three states, and each has its own paperwork and timing:

• Delayed — the bag is late but eventually shows up. Compensation covers reasonable interim expenses (toiletries, a change of clothes, work-appropriate items if you're traveling for business).
• Lost — most U.S. carriers declare a bag lost after 5–14 days of no location update. At that point you can claim the full value of contents up to the liability cap, subject to depreciation and exclusions.
• Damaged — you must report visible damage before leaving the airport, or as soon as reasonably possible for concealed damage.

The Montreal Convention deadlines are strict: 7 days from receipt to report damage, and 21 days from the date the bag was made available to file a delay claim in writing. Miss those and the carrier can refuse the claim outright.

How to file a delayed baggage claim

File in this order, and keep copies of everything. Airlines routinely deny claims for missing receipts or a late PIR — not because your case is weak.

1. Before leaving the airport, go to the baggage service office and file a Property Irregularity Report (PIR). Get the file reference number in writing.
2. Ask the agent what per-diem or interim expense allowance the airline offers on the spot (some give $50–$100 same-day for essentials).
3. Keep every receipt for essentials — toiletries, underwear, a work outfit, phone charger, a suitcase you had to buy. Take photos of tags and packaging.
4. Track the bag daily using the PIR number on the airline's site or WorldTracer.
5. Once the bag arrives (or is declared lost), submit the formal written claim through the airline's baggage claims portal within the deadline. Attach the PIR, boarding pass, bag tag, itemized receipts, and a short cover letter listing amounts.
6. If denied or lowballed, escalate: DOT complaint, credit card travel benefit claim, and — for international flights — a written appeal citing the Montreal Convention.

What expenses are reimbursable (and what isn't)

Reimbursable, in most cases: toiletries, a modest replacement wardrobe, cosmetics you can't live without for a few days, a phone/laptop charger, an inexpensive replacement suitcase, and, if you're traveling for a specific event, work- or event-appropriate clothing. Business travelers can often claim more aggressively because the essentials threshold is set against the purpose of the trip.

Usually excluded or heavily depreciated: electronics, cash, jewelry, prescription medications, negotiable documents, keys, artwork, and items on the airline's contract of carriage "excluded items" list. Read the fine print before you pack — most carriers explicitly disclaim liability for these, meaning even a Montreal Convention claim can be reduced to zero for those categories.

Depreciation is real. Airlines apply a percentage reduction based on age and condition for lost-bag claims. A three-year-old $200 pair of jeans might pay out at $60. Bring proof of purchase where you can — a bank statement line item beats nothing.

What to do when the airline denies or lowballs you

Denial letters are usually form responses. Don't accept the first "final offer." Options in order of speed:

• Appeal in writing to the airline citing the specific rule (14 CFR 254 or Montreal Convention Article 19/22). Attach the PIR and receipts again.
• File a DOT complaint at secure.dot.gov/air-travel-complaint. Airlines must respond within 60 days, and DOT tracks patterns for enforcement.
• Credit card chargeback — if you paid for baggage fees or the ticket on a card, dispute the baggage fee under "services not rendered" when a bag is lost.
• Credit card travel protection — Chase Sapphire, Amex Platinum and similar cards include baggage delay coverage (often $100/day for 5 days) that pays regardless of the airline outcome.
• State attorney general or small claims — for larger denied claims, small claims court is cheap and airlines often settle before the hearing.

If a broader pattern emerges — like an airline systematically underpaying claims — passengers sometimes bring class actions. See how a class action lawsuit works and how to check if you're part of one.

You are also owed your checked-bag fee back

Since 2024, DOT rules require U.S. airlines to automatically refund checked-bag fees when a bag is not delivered within 12 hours of a domestic flight's arrival, or 15–30 hours of an international flight's arrival (depending on flight length). This is separate from — and on top of — your interim expense reimbursement.

You should not have to ask. In practice you often do. If the fee hasn't been refunded to your original payment method within 7 business days of the delay threshold, email the airline citing the DOT automatic-refund rule and reference your PIR number. Screenshot your bag-tracking timeline showing when the bag actually arrived — that's your proof of the delay window.

If the airline stalls, file the DOT complaint. Automatic refund violations are one of the categories DOT actively enforces, and public complaints often trigger quick payment. This is one of the clearest, most winnable pieces of a bag-delay case.

Other money you may be owed while you're at it

A delayed bag often coincides with a delayed or canceled flight, and the two claims are independent. If the flight itself was canceled or significantly delayed for reasons within the airline's control, you may be owed a full refund of the ticket (again, mandatory under the 2024 DOT rule) even if you eventually flew. EU261 adds €250–€600 in cash compensation for flights departing the EU or arriving in the EU on an EU carrier.

While you're already digging through receipts, it's worth a five-minute scan of open class-action settlements — hidden-fee cases against airlines, ticketing platforms, and hotel booking sites pay out regularly. Browse the current settlements directory or see what you're owed in 30 seconds. See also how to find open settlements and no-proof settlements you can claim in minutes.
