Your Checked Bag Did Not Arrive: What to Do Before Leaving the Airport

1. Check the right places, then find the baggage-service desk

First, confirm that you are at the correct carousel and that unloading has finished. Look near the oversized-baggage area and any secured collection point. Airline apps sometimes show whether a bag was scanned onto the aircraft or reached the destination, but a missing scan does not prove the bag is lost. Save any useful tracking information rather than repeatedly refreshing the screen.

If the bag still has not appeared, go to the airline's baggage-service office, usually near baggage claim. On a connecting itinerary involving multiple airlines, start with the carrier that operated the final flight; it generally takes the initial report and coordinates tracing. Tell the agent if you changed flights, were rebooked or checked the bag under a different carrier's tag.

Do not quietly head home because the office is closed or the line is long. Use the airline's official online reporting tool, phone number or airport assistance channel immediately. Document when you tried to report the problem and any unavailable service. If staff direct you to file online, complete the submission and save confirmation before leaving whenever possible.

2. Leave with a report number and a delivery plan

Ask to file a delayed-baggage report, sometimes called a property irregularity report. Describe the suitcase precisely: color, size, brand if known, hard or soft shell, distinctive straps and identifying marks. A photograph taken before travel can help. Give the agent your baggage-tag number, itinerary and reliable contact information, then check the report for errors before accepting it.

Get a written or electronic copy with a reference number and tracking instructions. Confirm where the airline should deliver the bag, whether you must be present and how to update the address if you move hotels. Ask whether delivery is free in your circumstances and what happens if the bag arrives after you leave town. A tracing report usually does not, by itself, request reimbursement for purchases.

• Save your boarding pass, ticket receipt, baggage-tag stub and any checked-bag fee receipt.
• Record the report number, reporting time and the agent's name or service location.
• Confirm your phone number, email, delivery address and the dates you will be there.
• Ask for written instructions covering essential purchases, expense submissions and claim deadlines.

3. Buy essentials carefully and build a receipt trail

For flights covered by U.S. Department of Transportation baggage rules, airlines must reimburse reasonable, verifiable and actual incidental expenses caused by a baggage delay, subject to applicable liability limits. They cannot simply impose an arbitrary daily ceiling on those expenses. Still, reimbursement is not an unlimited shopping allowance. Necessity, price, delay length and whether you are away from home can matter.

Start with what you genuinely need before the bag is expected back: basic toiletries, underwear and appropriate clothing. A work meeting or cold-weather destination may justify different purchases than an overnight delay at home. Ask the airline for guidance, but distinguish its suggested spending amount from a binding legal limit. If someone authorizes a particular purchase, request written confirmation.

Keep itemized receipts, not just card statements showing store totals. Photograph paper receipts immediately and maintain a simple log explaining each purchase. Avoid replacing an entire wardrobe or buying premium substitutes without a clear reason. If medication or medical equipment is missing, seek prompt help from a pharmacist, clinician or equipment provider; do not delay essential care while waiting for reimbursement approval.

• Record the purchase date, item, cost, currency and why it was needed.
• Keep essential replacements separate from unrelated shopping whenever possible.
• Save messages showing delivery estimates, extensions and airline purchase guidance.
• Retain receipts for necessary rentals or laundry, with an explanation of the need.

4. Know what the airline's responsibility actually covers

For U.S. domestic travel in July 2026, the federal baggage liability limit is $4,700 per passenger, not per suitcase. An airline may offer a higher limit, but that figure is a ceiling on liability, not an automatic payout. Compensation depends on the documented loss and applicable rules. Used belongings are generally valued with depreciation rather than automatically replaced at today's retail price.

For most international itineraries covered by the Montreal Convention, the baggage limit is 1,519 Special Drawing Rights per passenger. An SDR is an international accounting unit, so its dollar equivalent changes. International rules can govern a domestic segment on an international itinerary. Ask which liability regime applies rather than assuming that a flight entirely within the United States necessarily uses the domestic limit.

Delay expenses and compensation for lost contents generally count toward the applicable baggage liability limit. Domestic contracts may exclude categories such as valuables, although airlines cannot apply the same exclusions under the Montreal Convention. Assistive devices can receive special protections, particularly on domestic flights. Declare missing disability-related equipment immediately and request specific assistance rather than treating it as ordinary clothing.

5. Put the reporting and claim deadlines on your calendar

Do not wait for the airline to declare the bag lost before checking deadlines. Domestic reporting and claim procedures vary by carrier, and some notice windows are short. Read the baggage page and contract of carriage, then ask which deadlines apply to your report, interim expenses and any eventual lost-property claim. Save the relevant instructions as they appeared when you filed.

For baggage delay under the Montreal Convention, submit a written complaint no later than 21 days after the baggage is placed at your disposal. For damage to delivered checked baggage, the written complaint deadline is generally seven days after receipt. Report problems immediately rather than using these as waiting periods. A tracking report may not satisfy every requirement for a written compensation complaint.

Under the convention, you can enforce rights arising from loss if the airline admits loss or the bag has not arrived 21 days after it should have arrived. Airlines may classify bags as lost earlier under their procedures. Court actions under the convention generally must be brought within two years, calculated under treaty rules; that is not an extension of shorter complaint deadlines.

• Calendar each deadline with an earlier reminder and retain submission confirmations.
• When the bag arrives, record the delivery time and inspect it promptly.
• If it remains missing, prepare a contents inventory with ages, values and available receipts.

6. Check the baggage-fee refund separately

A refund of the checked-bag fee is different from reimbursement for toiletries or compensation for a lost suitcase. Under DOT rules, a paid checked-bag fee generally must be refunded when the bag is lost or significantly delayed, provided you filed a mishandled-baggage report. For domestic flights, the significant-delay threshold is 12 hours after arrival.

For international flights to or from the United States, the threshold is 15 hours for flights lasting 12 hours or less, and 30 hours for flights lasting longer than 12 hours. Exceptions can apply, including certain passenger-caused delays in collecting or rechecking baggage. Keep arrival and delivery timestamps. If an expected automatic refund does not appear, contact the airline with the fee receipt and report number.

7. Treat credit-card coverage as a separate claim

A card's baggage-delay benefit is not the same as lost-luggage insurance, and many cards provide neither. Eligibility may depend on how you paid for the trip, who was traveling, the delay's duration and whether you were away from home. Open the current guide to benefits and contact the benefits administrator promptly; the airline's report does not notify the card insurer.

Some benefits cover specified essential purchases after a waiting period, with daily and total caps. Others reimburse eligible loss only after airline compensation or other insurance is considered. Exclusions, covered relatives, award-ticket requirements and notice deadlines vary. Ask whether you must submit to the airline first while also preserving the card claim deadline. Never seek duplicate payment for the same expense.

Keep one claim folder containing both sets of correspondence, receipts and decisions. If the airline denies an expense, request its reason in writing and compare it with the applicable rules. Escalate unresolved airline issues through customer relations and, when appropriate, a DOT complaint. The strongest claim is timely and specific, with a clear explanation of the actual financial loss.
