How is baggage tracked?

How can I track my luggage? Once you've checked in for your flight, the airline will provide tracking information for your luggage. In case your luggage gets lost or delayed, this tracking barcode will help the airline recover it. However, you can track your own luggage using Bluetooth and GPS tracking devices.



Baggage tracking in 2026 relies on a multi-layered digital infrastructure mandated by IATA Resolution 753, which requires airlines to track bags at four key points: check-in, aircraft loading, transfer between carriers, and arrival at the carousel. Most airports still utilize optical barcode scanning, where a laser reads the 10-digit number on your tag. However, there is a massive shift toward Radio Frequency Identification (RFID) technology. RFID tags contain a tiny chip that can be read wirelessly by sensors as the bag moves through the conveyor system, allowing for real-time location updates in airline apps. Some savvy travelers also add "crowdsourced" tracking by placing Bluetooth devices like AirTags inside their luggage. This combination of official airline scanning and personal GPS-style tracking has significantly reduced mishandling rates by providing a "digital twin" of the suitcase that can be located even if the paper tag is damaged or lost during transit.

Excellent question! Baggage tracking is a complex but fascinating system that combines physical tags, barcode/RFID scanning, and sophisticated software networks to follow your luggage from check-in to the carousel.

Here’s a breakdown of how it works, step-by-step:

1. The “License Plate” - The Bag Tag

When you check your bag, the airline agent prints a baggage tag (also called a baggage waybill). This is the most critical piece. Barcode: The traditional method. The tag has a unique 10-digit number (like 123ABC456) and a corresponding barcode. This number is your bag’s “license plate” for the entire journey. RFID (Radio-Frequency Identification): The newer, more accurate method. The tag contains a tiny, passive radio chip. Scanners can read these chips from a greater distance and without direct line-of-sight (e.g., through a conveyor belt curtain).

2. The Scanning Network - Key Checkpoints

Your bag is scanned at multiple points, creating a digital trail in the airline’s baggage handling system:

  • Check-in: First scan when the tag is attached.
  • Drop-off to Baggage System: Scanned as it enters the conveyor maze behind the check-in counters.
  • Sortation: The most important scan. Automated scanners read the tag and use destination codes to route the bag down the correct chute to be loaded into:
    • A container for wide-body aircraft, or
    • A cart for narrow-body aircraft.
  • Loading: Often scanned again as it’s loaded onto the specific aircraft to confirm.
  • Transfer: At connecting airports, it’s scanned as it’s unloaded and re-routed to the next flight.
  • Arrival: Scanned as it’s unloaded and sent to the correct baggage carousel.

Resolution 753 makes it obligatory to track baggage at specific stages: upon acquisition from the passenger, delivery to the aircraft, during custody transfers between carriers, and upon final delivery to the passenger.

After your Apple AirTags are set up, you can use them to track your luggage. Make sure you have at least one AirTag per bag you want to track. In addition to placing an AirTag in checked luggage, consider placing an AirTag in your carry-on bag.

Airlines are using RAIN RFID-enabled luggage tags to give each item a unique identification code that is automatically scanned as it goes through checkpoints.

The Federal Aviation Administration has even ruled that having an AirTag in your luggage is permitted and, in fact, not a safety hazard. The devices only contain 0.1 grams of lithium, which falls below the FAA's limit.

This seems to be a responsible choice when traveling, however, some airlines state that they hate these small trackers. Airlines expressed their concern over the fact that AirTags have the potential to interfere with the aircraft's navigation system.

Lufthansa created all sorts of unnecessary confusion after it initially banned AirTags out of concern that they are powered by a lithium battery and could emit radio signals and potentially interfere with aircraft navigation.

How long do luggage trackers last? The only con is that most of these trackers expend their battery much quicker than a AirTag or SmartTag. While those luggage trackers can last months, a GPS tracker may only last a few days.
