How to Track Lost Luggage: Steps, Trackers and Claims

If your bag did not come down the carousel, do three things before you leave the airport: file a report with the airline and get your file reference number, then check the bag’s status online, then check your own tracker if you packed one. The reference number is what lets the airline’s system find your bag. A tracker in the bag tells you where it is, which can save hours of back and forth.

This guide covers both sides: what to do right now if a bag is missing, and how to set up a luggage tracking device so the next trip is less stressful.

TL;DR

  • Most “lost” bags are only delayed. About 77% of mishandled bags are delayed and about 5% are permanently lost or stolen.
  • Report the missing bag at the airport before you leave and get the 10-character file reference number. Without it, you cannot use the shared tracing system.
  • Put a small tracker in an internal zippered pocket of every checked bag. Bluetooth tags and GPS trackers are allowed in checked luggage under current rules, but check the battery type of any device you pack.
  • File claims fast: delayed-bag claims often have a 21-day window and damage claims as little as 7 days, and the exact limit depends on your airline.

First, how likely is it that your bag is really lost?

The odds are better than the panic suggests. SITA’s annual baggage report counted 33.4 million mishandled bags worldwide in 2024, down from 36.7 million the year before. That works out to 6.3 bags per 1,000 passengers, against 6.9 in 2023.

Mishandled baggage totals and rates by year

“Mishandled” is a broad label. It covers delayed, damaged, pilfered and lost bags. Industry data shows that roughly 74% to 77% of cases are simply delayed, meaning the bag took a later flight. Only a small share never come back.

Where you fly matters too. Among large US carriers, 2024 Department of Transportation data put Allegiant at 0.20 mishandled bags per 100 enplaned passengers, while American Airlines had the highest rate at 0.79 per 100. The same source adds the practical point: connections are where bags get lost, so a tight connection through a big hub carries more risk than a nonstop flight.

Two habits follow from that. Book longer connections when you can, and assume that any checked bag could be delayed by a day, so keep essentials in your carry-on.

What to do the moment your bag does not show up

Speed matters, and so does order. Follow these steps in sequence.

  1. Stay at the airport and find the baggage service desk. Do this before you exit the baggage claim area. Airlines such as Virgin Australia ask you to report loss or damage inside the reclaim area, and Air Transat tells passengers to speak to a representative at the arrival airport and complete a Property Irregularity Report (PIR).
  2. Get your file reference number. It is a 10-character code. Aer Lingus explains that it is the key to tracing your bag, and leaving without it is a common mistake. Photograph the paperwork.
  3. Give a delivery address you can actually receive at. Hotel name, room number and a phone number that works abroad or locally. If you are going on to another city, say so.
  4. Describe the bag precisely. Brand, color, size, wheels, straps, any ribbon or sticker. Show a photo of the bag from your phone. Staff match this against bags sitting unlabeled in the system.
  5. Ask what the airline will cover now. Many airlines reimburse reasonable essentials such as toiletries and a change of clothes while a bag is delayed. Policies differ, so ask and keep every receipt.

Track the bag through WorldTracer

WorldTracer is the database airlines use to share baggage data. Airline staff consistently say it is the best way to follow a case, and that repeatedly emailing different airline departments is the usual mistake. With your file reference number, you can update your own contact details and delivery address in the online portal, which is often faster than waiting for an agent to do it.

Check it once or twice a day. If the status does not change for several days, call the airline’s baggage line, quote the reference number, and ask which station is holding the file.

Check your own tracker

If you had a tracker in the bag, open its app now. Take a screenshot of the last known location and the time. Two things to know:

  • A Bluetooth tag only updates when another compatible phone passes near it. In an airport hub it will probably update. In a sorting area or a warehouse far from the terminal it may not, so absence of a ping is not proof the bag is gone.
  • A GPS tracker with its own cellular connection reports independently of nearby phones, which makes it better suited to checked bags that spend hours in the baggage system.

Show the location to the airline agent. It will not replace the official process, but it can point staff to the right belt, aircraft or station. Do not go into restricted areas or try to retrieve the bag yourself.

Delayed, lost or damaged: the deadlines that matter

Claims have clocks, and they start earlier than most travelers expect.

Situation Typical window What to do
Bag does not arrive Report before leaving the airport File the PIR, get the reference number
Delayed bag, claim for expenses Often 21 days from the date you receive the bag Submit receipts and the reference number
Damaged bag Often as short as 7 days from receipt Photograph damage, report at once
Bag still missing after a few weeks Set by each airline Ask for the written lost-bag claim process

The 21-day and 7-day figures come from one airline’s published policy and are typical rather than universal. For your trip, read your carrier’s own baggage page and the contract of carriage. For a US domestic flight or a flight to or from the US, you can also ask the airline how it handles its own liability limits, or contact the Department of Transportation’s aviation consumer protection office if you cannot get an answer.

Failing to file a PIR at the airport can badly weaken a claim. If you did leave without one, contact the airline’s baggage service the same day and say so plainly, then follow up in writing.

Can you put a GPS tracker in checked luggage?

In most cases, yes, but the answer depends on the kind of device.

Bluetooth tags use a small coin cell, typically a CR2032. These stay well under the 2-watt-hour threshold that triggers restrictions on power banks and smart-luggage batteries, according to reporting that cites ICAO and IATA guidance. That source also says they are permitted in both carry-on and checked bags under TSA and FAA rules. The airline industry had a brief scare in 2022 when Lufthansa reversed a ban on these tags after consulting German aviation authorities.

GPS trackers with a rechargeable battery are a different category from a coin-cell tag. TSA lists navigation GPS devices as allowed in both carry-on and checked bags, but the final decision rests with the officer. Lithium-ion batteries are the concern for airlines, so before you pack one, check the battery capacity printed on the device or in its manual, and read your airline’s policy on batteries in checked bags. If you are unsure, carrying the device in your cabin bag is the conservative choice, and you can still use it to track the bag you check by placing a compliant tag inside.

This is a safety rule, not a gadget preference, so do not guess. When a device does not state its watt-hour rating, ask the airline before the flight.

Bluetooth tag or GPS tracker: which suits your trip?

Bluetooth tag GPS tracker with cellular
How it locates Relays through nearby phones Reports its own position
Best for Busy airports, crowded routes Remote routes, long transfers
Battery Coin cell, lasts many months Rechargeable, needs charging before the trip
Size Very small Usually slim card or small puck
Ongoing cost Usually none May need a plan or subscription, check before buying

Neither is magic. A Bluetooth tag in a quiet corner of a warehouse may not update for hours. A GPS tracker with a flat battery tells you nothing. If you fly often, check what service each device needs, charge it the night before, and test it at home by walking away from it with the app open.

Where to hide it in the bag

Placement decides whether a tracker survives the trip. Experts quoted in the same reporting say the biggest risk is physical damage from baggage handling equipment when a tag hangs on the outside, where it can be snagged, lost or crushed.

  • Use an internal zippered pocket, ideally in the lid of the suitcase, away from the wheels and handle.
  • Tuck it into a packing cube or the lining of a zipped compartment so it cannot slide around.
  • Do not use an external keychain loop for a checked bag.
  • Put a second tracker in your backpack or laptop bag. Cabin bags get left in taxis and on trains, too.
  • Add a paper tag with your phone number and email inside the bag, not only on the outside.

Placing a tracker in a checked bag gives the highest practical recovery value, as one travel guide citing SITA data puts it, because that is the bag that leaves your sight.

Our view on tracking luggage

We sell everyday tech to people who want practical gadgets without complicated buying decisions, and luggage tracking is one of the clearest cases where a small device pays for itself in calm. Here is how we think about it.

First, a tracker does not replace the airline’s process. It gives you information, and the report and file reference number still do the real work. Treat the tracker as evidence and speed, not as a way to skip the desk.

Second, charge and test before you go. Most tracker disappointments we hear about come from a dead battery or an app that was never set up, not from the hardware itself.

Third, think about who is traveling. A student with one duffel bag, a family with four suitcases and a driver on a road trip need different things. Buy per bag, not per trip, and keep one for the items you cannot replace.

Finally, shop for simplicity. Clear battery information, a straightforward app and a return window matter more than a long feature list. That is why we pair every order with a 30-day money-back guarantee.

Preparing before you leave home

Most of the pain of a lost bag can be reduced the night before the trip.

  • Photograph your bag and its contents. A clear picture of the outside helps staff identify it. A packed-contents photo helps with a claim.
  • Take the airline’s baggage tag photo. After check-in, snap the tag and the receipt with the 10-character bag tag number.
  • Pack a 24-hour kit in your carry-on. Medication, a charger, one change of clothes, toiletries, glasses and travel documents. Never check anything you cannot replace.
  • Remove old tags. Old airline tags can confuse scanners.
  • Save the baggage contact. Put the airline’s baggage service number and your reference code in your phone’s notes.
  • Check your insurance. Some travel insurance and some credit cards cover delayed baggage expenses. Read your policy for limits and for what you must prove.

If your route has a short connection, pick a nonstop or a longer layover. According to analysis of airline rankings, connections are where most bags go missing.

FAQ

How do I locate lost baggage?

File a report at the airport and get your file reference number, then follow your case in the online tracing portal your airline links to. If you packed a tracker, check its app and show the last location to the agent. Keep checking daily and call the airline’s baggage line if the status does not move.

Can I put a GPS tracker in my luggage?

Usually yes. TSA lists navigation GPS devices as allowed in checked bags, and small coin-cell Bluetooth tags are also permitted. Check the battery on any rechargeable device and your airline’s rules before you fly, because the final decision rests with the officer and the carrier.

How long until a delayed bag is considered lost?

There is no single rule, because each airline sets its own timeline. Most delayed bags arrive within a day or two, and only about 5% of mishandled bags end up permanently lost or stolen. Ask your airline when it moves a file to a lost-bag claim and keep your receipts from day one.

Should the tracker go in my carry-on or checked bag?

Put one in your checked bag, because that is the bag you cannot see. Place it in an internal zippered pocket, not on an outside keychain. If you carry a laptop bag or backpack you would hate to lose, give it a second tracker.
