Bag Tag Proof: What to Keep and What to Photograph

When a bag is lost or damaged, airlines default to the lowest-effort payout unless you can prove otherwise. The bag tag number is how the airline traces your bag. The photos and contents list are how you prove value. Without them, you get a depreciated minimum. With them, you get reasonable replacement value.

The single most common reason airlines lowball baggage claims: insufficient proof of contents and condition. Photos take 30 seconds at check-in and save hundreds of dollars in claim negotiations.

1. 1

   Photograph the outside of the closed bag from multiple angles so you have clear before-photos.

2. 2

   Photograph the bag tag after the airline attaches it, so you have the tag number visible on the bag.

3. 3

   Photograph the receipt the airline gives you at check-in (this shows the tag number and flight routing).

4. 4

   Photograph the bag's contents as you pack. Especially high-value items (laptops, cameras, jewelry, electronics, prescription medications).

5. 5

   Email yourself the photos so they are accessible even if your phone is stolen or lost.

The airline attaches a paper tag to the bag. You receive a matching paper receipt at check-in, often with a sticky back. Keep it.

• ›

  Bag tag receipt: 10-digit number matching the tag on the bag. This is the single most important piece of paper.

• ›

  Boarding pass: the paper or PDF version, showing your name and flight.

• ›

  Credit card receipts for bag fees paid.

• ›

  Any declared value form if you declared excess value at check-in.

• ›

  Customer service emails with any special handling requests.

Airlines destroy their bag tag attachments when the bag arrives. Your receipt is often the only surviving reference to the tag number.

At baggage claim, when the bag does not arrive:

1. 1

   Photograph the empty baggage carousel showing your flight number on the display.

2. 2

   Photograph the baggage service desk including the counter and any signage.

3. 3

   Photograph the PIR form before leaving (front and back).

4. 4

   Photograph your boarding pass showing arrival time.

5. 5

   Note the PIR reference number and photograph it alongside the PIR.

1. 1

   Multiple angles of the damage from different distances and lighting.

3. 3

   A second photo with a ruler or common object for scale.

4. 4

   Any contents that were damaged inside the bag.

5. 5

   Photograph before moving the bag out of the arrival terminal.

Airlines typically ask for a contents list when you file a lost bag claim. The more specific, the higher the payout. Spend 5 minutes before every trip:

• ›

  Open your bag and photograph it packed. One photo per side/angle.

• ›

  Photograph each high-value item individually with any serial numbers visible.

• ›

  Save receipts (or screenshots of online purchase confirmations) for electronics, jewelry, art, prescriptions.

• ›

  Note age of each item and approximate original cost.

• ›

  Store the documentation in email or cloud storage for retrieval after loss.

Photos + receipts beat depreciation tables. Airlines typically start offers at 30% to 50% of claimed value. With photos and receipts, the offer rises to 70% to 100% of replacement cost.

• ›

  Weight tag on the bag tag receipt (some carriers show weight).

• ›

  Luggage locks in photos prove the bag was secured.

• ›

  Declared value form if you declared excess value.

• ›

  Trip itinerary showing business purpose if relevant.

• ›

  Passport entry stamp or boarding pass confirming the trip actually occurred.

• ›

  Travel insurance documentation if applicable for double recovery, see the baggage claim vs travel insurance guide.
