Report the loss to the airline before you leave the airport
The moment you realize your bag did not arrive, go to the airline's baggage service desk in the airport terminal. Do not leave the airport without filing a report. The airline needs to document the loss while you are still there, and the process is faster when you do it in person rather than calling later.
Bring your boarding pass and any baggage tags or receipts you have. Tell the agent exactly what was in the bag, including brand names and approximate values of items. The airline will ask you to describe the luggage itself — color, size, material, any distinctive marks. Be as specific as you can. They will give you a Property Irregularity Report (PIR) or Baggage Irregularity Report — the exact name varies by airline, but it is the official record of your claim.
Ask the agent for a copy of this report and keep it. Write down the report number, the date, the agent's name, and the phone number for the airline's baggage department. You will need these details later.

What happens during the search period
After you file the report, the airline begins searching for your bag. This usually takes 5 to 21 days. The bag may have been loaded onto the wrong flight, sent to a different airport, or delayed in the baggage system. Most lost bags turn up within the first week.
The airline will contact you if they find it. Make sure the phone number and email address on your report are current. If the bag is found, the airline will deliver it to you — usually at your home address, though some airlines offer airport pickup. Delivery typically happens within a few days of the bag being located.
During this waiting period, you may need clothes, toiletries, or medications. Some airlines offer a cash advance or will reimburse you for emergency purchases if you keep receipts. Call the baggage department number on your report and ask what the airline's policy is. The amount and whether they require receipts before or after you buy items varies by carrier.
Filing a claim if the bag is not found
If the airline cannot locate your bag after 21 days, they will declare it lost. At this point, you can file a claim for the contents. The airline will send you a claim form — ask for it if they do not offer one automatically.
On the form, list every item that was in the bag with its approximate value. For expensive items like electronics, jewelry, or luggage itself, include the original receipt if you have it, or a photo, or a description of where and when you bought it. The airline may ask for proof of value, especially for items over a certain amount.
Different airlines have different limits on what they will pay per bag. Some cap reimbursement at $2,500 or $3,000 per bag; others have lower limits. Check your airline's policy on their website or ask the baggage department. If your bag contained items worth more than the airline's limit, you may have purchased baggage insurance when you booked your ticket, which could cover the difference — check your booking confirmation.
Keep receipts for replacement purchases
If you had to buy essential items while waiting for your bag or after it was declared lost, keep every receipt. Reasonable emergency purchases — a change of clothes, toiletries, medications, underwear — are often reimbursed by the airline, especially if you bought them within the first few days after the loss.
Do not buy expensive replacement items expecting full reimbursement. The airline will reimburse what is reasonable for the circumstances. If you were traveling for three days and bought a $400 winter coat because your bag was lost, the airline may not cover the full cost. If you bought a $30 toothbrush and basic clothing, they likely will.
Submit receipts along with your claim form. If you do not have physical receipts, email confirmations from retailers or credit card statements showing the purchase can work as backup.
What to do if the airline denies your claim
The airline may deny your claim if they say the bag was not lost due to their negligence, or if the items you listed were not actually in the bag, or if the value you claimed exceeds what they can verify. Read the denial letter carefully — it will explain their reason.
You can appeal the decision. Write to the airline's customer service department with a letter explaining why you believe the claim should be paid. Include copies of your original report, receipts, and any other evidence. Keep a copy for your records.
If the airline continues to deny the claim and the amount is significant, you can file a complaint with the U.S. Department of Transportation (DOT) if you were flying a U.S. airline, or with your country's aviation authority if you were flying internationally. The DOT has a consumer complaint form on its website. Filing a complaint does not may provide payment, but it creates an official record and may prompt the airline to reconsider.
Baggage insurance and what it covers
Some airlines offer baggage insurance as an add-on when you book. Some credit cards include baggage coverage as a cardholder benefit. If you purchased either, check the policy to see what it covers and what the claim process is.
Airline baggage insurance typically covers lost, delayed, or damaged luggage and may have higher limits than the airline's standard liability. Credit card baggage coverage often reimburses you for essential items purchased while your bag is delayed, or for the contents if the bag is lost. The coverage amount and what qualifies varies widely by card and issuer.
If you have baggage insurance or credit card coverage, you may be able to file a claim with the insurance company or card issuer in addition to or instead of claiming through the airline. Read your policy to understand the process and whether you need to exhaust the airline's claim first.
How to prevent luggage loss on future trips
Use a distinctive luggage tag or mark your bag in a way that makes it stand out. Solid black or navy luggage looks like thousands of other bags. A bright color, a unique tag, or a ribbon tied to the handle makes your bag easier to spot and less likely to be grabbed by mistake.
Take a photo of your luggage before you travel, including any identifying marks. If your bag is lost, you can show this photo to the airline. Keep your boarding pass and any baggage tags until you have retrieved your checked luggage at your destination.
For valuable items, consider carrying them in your carry-on bag instead of checking them. Airlines are not liable for loss or damage to items in checked baggage beyond their stated limits, so irreplaceable items, medications, electronics, and jewelry should travel with you in the cabin.
Frequently Asked Questions
How long does the airline search for a lost bag?
Most airlines search for up to 21 days after you report the loss. If the bag is not found by then, it is declared lost and you can file a claim for its contents. Some bags turn up after 21 days, but the airline is no longer obligated to search or deliver it.
Can I get money right away if my bag is lost?
Many airlines offer a cash advance or emergency reimbursement for essential purchases while your bag is being located. Call the baggage department and ask what your airline offers. The amount and process vary, so confirm the details before you spend money.
What if my bag arrives damaged instead of lost?
Report damage to the baggage desk before you leave the airport, just as you would for a lost bag. The airline will document the damage and may reimburse you for repairs or replacement of damaged items. Keep the damaged bag and take photos of the damage for your claim.
Do I need receipts to prove what was in my lost bag?
Receipts help, but they are not always required. You can list items from memory and estimate their value. For expensive items, receipts or photos strengthen your claim. If you do not have receipts, a credit card statement showing a purchase, a photo, or a description of where you bought the item can serve as evidence.
What if I was flying internationally?
International flights are covered by different rules depending on which countries were involved. Most international flights fall under the Montreal Convention, which sets liability limits for lost baggage. The process for reporting and claiming is similar to domestic flights, but the compensation limits may be different. Ask the airline which rules explore to your flight.
