Five years ago, the only tracking on a bag was the barcode on the airline tag. Today, most travelers can watch their bag move through the airport in real time using a $30 tracker they drop in the bag. The technology is now good enough that airlines have adapted their processes to accept passenger tracking data as evidence.
Physical trackers
| Tracker | Network | Battery life | Best for |
|---|---|---|---|
| Apple AirTag | Apple Find My (~1.5 billion devices) | 1 year | iPhone users, largest network |
| Tile Pro | Tile network (~40 million users) | 1 year, replaceable | Android users |
| Chipolo Card | Apple Find My or Google | 2 years, non-replaceable | Wallets, thin cases |
| Samsung Galaxy SmartTag2 | Samsung Find network | 1.5 years | Samsung users |
For an iPhone user with a mixed itinerary, AirTag is essentially the default. The Find My network is dense enough in major airports that location updates come every few minutes. The one gap: some Chinese airports and a few very small regional airports have coverage gaps of 6-12 hours.

Airline tracking
Most legacy airlines now offer bag tracking through their app. It uses the bag tag barcode and shows major status events:
- Checked in.
- Loaded onto aircraft.
- Arrived at destination.
- Delivered to carousel.
- Delayed and traced (if applicable).
This system is entirely airline-controlled and only updates when the bag passes a scanner. If the bag is loaded on the wrong flight and the wrong scanner captures it, the app can show 'loaded' while the bag is going to a different city. AirTag catches this; the airline system does not.
Using the data
If AirTag shows your bag at the origin airport after your flight has landed:
- File the PIR at your destination baggage service office.
- Show the agent the AirTag screenshot with a timestamp.
- Ask them to check WorldTracer for a matching found-bag report at your origin.
- Give them your current location for delivery.
- Keep AirTag open and screenshot each location as the bag moves.
If AirTag shows the bag at a third airport (a hub, or somewhere unexpected):
- The bag is likely on its way but was routed via a different hub. This is common and usually resolves in 24-48 hours.
- File the PIR anyway - the airline needs the paperwork to deliver.
- The screenshots become documentation if you need to claim later.
If AirTag shows the bag stopped moving and stays in one place for many hours after normal delivery windows:
- That location is likely an airline warehouse or lost-and-found holding area.
- Call the airline's local baggage service office directly (not general customer service).
- Provide the AirTag location; agents at the same airport can often physically locate the bag within an hour.

Frequently asked
Are AirTags banned by any airline?+
No. Lufthansa briefly considered a ban in 2022 but reversed the position. As of early 2026, no scheduled airline prohibits AirTags or similar trackers in checked bags.
Do I need to declare the tracker?+
No. Trackers use a small lithium button cell battery, well below any regulatory threshold.
What if the tracker's battery dies mid-trip?+
The bag continues to be visible on the network as long as it stays near a device from that network, but stops broadcasting fresh signals. Replace the battery before long trips.
