Lost Luggage: Step-by-Step Recovery Guide

The carousel slows. Then it stops. The last bag has been claimed and it wasn't yours.

There's a specific sinking feeling in that moment — and a specific mistake most people make in the next ten minutes. They walk out of the airport.

Don't. What you do in the baggage hall, before you leave the building, determines almost everything about whether you get your bag back and whether you get paid for the trouble. This is the lost luggage what to do guide, in the exact order the steps actually matter.

Lost Luggage: What to Do in the First 2 Minutes

If you're standing at an empty carousel right now, here's the whole lost luggage what to do sequence:

1. Go to the baggage desk in the arrivals hall — before you exit.
2. File a PIR (Property Irregularity Report). This is the single most important step.
3. Get your file reference number and photograph everything.
4. Buy only essentials and keep every receipt.
5. Claim in writing within the deadline — 21 days for delayed, 7 days for damaged.

Now the detail — every lost luggage what to do step below assumes you haven't left the terminal yet.

Step 1: File the PIR Before You Leave (Lost Luggage? What to Do First)

If you take one thing from this entire lost luggage what to do guide, take this: do not leave the baggage claim area without filing a Property Irregularity Report.

The PIR is the official form that logs your bag as missing. It is the foundation of every claim you will make afterwards, and without it, you have almost nothing.

This step is critical and time-sensitive. You must file a PIR before leaving the airport baggage claim area — if you leave without filing, it becomes significantly harder to pursue a claim, and some airlines will reject it outright.

Here's the lost luggage what to do sequence at the desk:

• Find the right desk. Go to the airline's baggage desk or its handling agent's desk in the arrivals area — not the check-in desk. It's usually within sight of the carousels.
• The agent searches World Tracer, the global baggage-tracking system, using your bag tag.
• If it can't be located immediately, you complete the PIR.
• You'll need your baggage tag — the sticker you were given at check-in — so don't throw away your boarding pass or the tag stub.

You'll be issued a file reference number. Guard it: everything downstream — tracking, claims, follow-ups — runs on that number.

If there's no desk and no staff, most airlines have an online form. Use it immediately and screenshot the confirmation.

Step 2: Document Everything, Right Now

The next lost luggage what to do move is evidence. Before you leave the terminal, spend three minutes building your file. Future-you will be grateful.

• Photograph the PIR and the reference number.
• Photograph your bag tag and boarding pass.
• Write down the agent's name and the time.
• Note what was in the bag while it's fresh — a rough inventory with approximate values. Airlines will ask you to document contents as specifically as possible.

Ideally you did some of this before you flew: a photo of your bag and a list of its contents makes any claim dramatically easier. If you didn't this time, do it before your next flight — and keep it somewhere you can actually find.

Step 3: Delayed vs Lost — They're Not the Same Claim

This distinction matters legally, it changes your entire lost luggage what to do approach, and airlines rely on people not knowing it.

Delayed means your bag is late but traceable. Most delayed bags turn up within a couple of days. A baggage delay is any bag that doesn't arrive at the same time you do.

Lost is a formal status. A bag is only officially considered lost once it has been missing for 21 days. In practice, most airlines will declare a bag lost somewhere between five and fourteen days, though this varies by carrier.

Why it matters: for a delayed bag you claim back the essentials you had to buy while waiting. For a lost bag you claim the value of the bag and its entire contents. Different claims, different forms, different numbers.

So the honest lost luggage what to do answer in the first week is: assume it's delayed, act as though it might be lost, and start the paper trail immediately.

Step 4: Lost Luggage — What to Do About Replacing Essentials

You're allowed to buy replacements for essentials while you wait, and the airline is meant to reimburse you. But "reasonable" is doing a lot of work in that sentence.

Generally reimbursable: underwear, a change of clothes, toiletries, any medication, a phone charger, small laundry costs.

Generally not: a shopping spree. Extras like souvenirs won't be refunded. Buying a designer coat because your fleece is in the missing bag will not fly.

Two lost luggage what to do rules for spending:

• Keep every single receipt. No receipt, no reimbursement — this is the most common reason claims fail.
• Buy in proportion. If your bag is 24 hours late, you need a toothbrush and a shirt, not a new wardrobe.

If you had prescription medication in the bag, an emergency replacement prescription is generally claimable — though the real lesson there is never to check medication in the first place.

Step 5: Know the Deadlines — Miss Them and You Get Nothing

This is the part that catches people out, and it's why so many valid claims fail.

For international flights, the Montreal Convention governs. It sets hard deadlines, and once you miss them, you lose your right to compensation from the airline entirely.

Situation	Deadline to claim in writing
Damaged bag	7 days from receiving it
Delayed bag	21 days from the day you actually receive it
Lost bag	Bag deemed lost after 21 days; claim from then

Two details people get wrong:

• The 21-day clock for a delayed bag runs from the day you received the bag — not from your flight date.
• The claim must be in writing (email counts). A phone call to the airline does not preserve your rights.

Don't sit on it. Submit as soon as you have receipts, while the delay is fresh and documented — don't wait until the deadline.

Step 6: File the Actual Airline Claim Form

The PIR reports the problem. The claim asks for money. They are two separate things, and this is where most people stall.

Every major airline has a dedicated baggage claim form — usually at airline.com/baggage-claim or linked from their Contact page. To find yours, search "[airline name] baggage claim form" rather than digging through the main site.

A complete lost luggage what to do claim should include:

• Your PIR file reference number
• Your flight details and booking reference
• Your bag tag number
• An itemised list of what was lost or what you bought, with values
• Scanned receipts for every expense
• Photos of the bag and any damage

For an international flight, state explicitly that your claim is made pursuant to Article 17 of the Montreal Convention, which is the provision making airlines liable for checked baggage. Citing it signals you know your rights, and claims that cite it get taken more seriously.

Be prepared for an initial rejection — many airlines reject first claims as a matter of course. Providing written proof of all circumstances and deadlines significantly increases your chances. A polite, well-documented resubmission works far more often than people expect.

Step 7: Know What You're Actually Owed

Be realistic about the numbers, because every lost luggage what to do outcome is capped:

US domestic flights: DOT regulations let airlines cap liability for a lost, damaged, or delayed bag, but the maximum liability allowed is $4,700 per passenger.

International flights: The Montreal Convention limit is currently 1,519 Special Drawing Rights — roughly $2,175 per passenger. This is a hard cap. If your bag was worth $3,000, the airline is still only liable up to that limit.

A few things worth knowing:

• Airlines must also refund any baggage fee you paid to check the bag that was lost. Ask for it — they won't volunteer it.
• Compensation is subject to depreciation. A three-year-old jacket isn't reimbursed at its original price.
• You can raise the cap by declaring excess value at check-in for a surcharge — worth it only for genuinely valuable items.
• On a multi-airline itinerary, you can choose which airline to claim from. Pick the one most likely to pay.

What isn't covered: no compensation is paid for inconvenience or lost time, and airlines aren't responsible for damage caused by improper packing.

Step 8: Lost Luggage? What to Do If the Airline Stalls

If the airline goes quiet or lowballs you, the lost luggage what to do escalation path is:

• Resubmit in writing, referencing your original claim date (proving you met the deadline).
• Check your travel insurance and credit card — many cards include baggage cover, and it often pays faster than the airline.
• Escalate to the regulator. In the US, that's the DOT. If an airline unreasonably refuses to declare a bag lost after an excessive period, it can face DOT enforcement action.
• Consider a claims service if the sum is large and you're getting nowhere.

Lost Luggage, What to Do Next Time: A Five-Minute Insurance Policy

Almost every painful part of a lost luggage what to do situation can be prevented in five minutes before you fly.

• Photograph your packed bag and its contents.
• Put a tracker in it. An AirTag or similar is now standard advice — and being able to tell an agent exactly where your bag is changes the conversation entirely.
• Label it inside and out with your name, phone, and email.
• Never check medication, keys, passport, valuables, or anything irreplaceable. The DOT explicitly warns against putting these in checked bags.
• Pack one change of clothes in your carry-on. The single highest-value habit in travel.
• Don't check in at the last minute — even if you make the flight, your bag may not.

And keep your booking reference, bag tag, and flight details somewhere you can reach in seconds. When you're standing at a baggage desk, the agent needs your PNR and tag number immediately — and the difference between a five-second answer and five minutes of scrolling through your inbox is the difference between a calm conversation and a bad one. That's exactly why we built Tripmojo: every booking, ticket and confirmation in one itinerary, saved offline, ready when it goes wrong.

Lost Luggage: What to Do — Quick FAQ

How long until my bag is officially lost? 21 days from filing the PIR is the standard threshold, though many airlines declare it sooner — typically between five and fourteen days.

Can I claim if I didn't file a PIR? It's much harder, and some airlines will reject the claim outright. File the PIR before leaving the airport. If you've already left, contact the airline immediately anyway — don't assume it's hopeless.

What's the maximum I can get? Around $4,700 per passenger on US domestic flights, and roughly $2,175 (1,519 SDR) on international flights under the Montreal Convention.

Do I need receipts for the lost contents? Not strictly for everything, but they enormously strengthen your claim — and airlines can require proof for valuable items.

My bag arrived, but damaged. What now? Different clock: you have 7 days from receiving it to claim in writing. Photograph the damage immediately and report it before leaving the airport if you can.

The Bottom Line

The lost luggage what to do playbook is simple, and almost nobody follows it: file the PIR before you leave, document everything, keep the receipts, claim in writing before the deadline.

Bags get found. The vast majority turn up within days. What doesn't get recovered is the money you were owed but never claimed — because you walked out of the airport without a form, or missed a deadline you didn't know existed.

Now you know it exists.
