Airlines Warn Against AirTags in Checked Bags — Here’s the Real Reason

Nearly 26 million pieces of luggage were mishandled by airlines globally in 2022, according to industry consultancy SITA. That single number explains why millions of travelers started tucking Apple AirTags into their suitcases without a second thought. The little white disc felt like the ultimate travel hack: cheap, discreet, and capable of pinpointing your bag anywhere on Earth.

Then the warnings started arriving. Delta Airlines, British Airways, and Air Canada have all issued advisories urging passengers not to place AirTags inside checked luggage. Suddenly, the travel hack that felt like common sense has become contested territory.

The question worth asking is not just whether you should keep using AirTags. It’s why airlines are pushing back in the first place.

The Lithium Battery Argument Airlines Keep Making

The official justifications tend to cluster around one technical concern: the battery. AirTags run on a CR2032 coin-cell lithium-metal battery, a non-rechargeable type that aviation regulators treat with particular caution. Some airlines have argued that placing these devices in checked bags may conflict with rules governing lithium-ion batteries in the cargo hold.

There’s a problem with that argument. The TSA explicitly permits AirTags in both carry-on and checked luggage. The agency does enforce strict rules around lithium-metal batteries, but an AirTag’s single, sealed CR2032 cell falls well within accepted thresholds. No federal aviation body has issued a blanket prohibition.

Lufthansa briefly banned AirTags outright in 2022, citing similar battery and Bluetooth signal concerns. The airline later reversed course, framing the reversal as part of its broader digital innovation strategy. That pivot quietly acknowledged what critics had said from the start: the battery rationale was thin.

What Delta, British Airways, and Air Canada Actually Cite

Beyond battery rules, the three airlines point to three overlapping concerns: reliability issues with the tracking data, data privacy risks, and the inherent limitations of Bluetooth-based location technology inside a cargo hold.

Reliability is a legitimate issue. AirTags use Apple’s Find My network, which depends on nearby Apple devices pinging the tag’s Bluetooth signal and relaying its location anonymously. Inside a sealed baggage hold, surrounded by metal and cargo, that signal can drop entirely. A traveler watching their AirTag show a last-known location from three hours ago is not getting real-time data.

Data privacy adds another dimension. When an AirTag travels through airport systems, its location pings pass through Apple’s infrastructure. Airlines argue this creates an uncontrolled data stream that intersects with their own operational data. Some airline staff have also noted that passengers armed with real-time bag location data are more likely to confront workers directly when something goes wrong, creating friction at the baggage claim counter.

The Integration Play Airlines Aren’t Fully Advertising

Here is where the story gets more interesting. According to reporting from TheStreet, some airlines are moving toward integrating AirTag data directly into their own systems. Under this model, an AirTag placed inside a passenger’s luggage could be synced to the airline’s tracking platform and shared with ground crew.

That changes the framing entirely. If airlines can absorb the AirTag data stream into their proprietary infrastructure, the tracking becomes their asset, not the passenger’s independent tool. The warnings against personal use start to look less like safety guidance and more like a precursor to a managed, monetized version of the same technology.

“Airlines’ dramatic claims about their AirTags tech may be exaggerated” — a conclusion that rewards scrutiny when you consider how quickly the conversation has shifted from banning the devices to integrating them.

Travel experts quoted in UK regional outlets this summer urged British holidaymakers specifically to avoid placing AirTags in checked luggage, citing the unreliability of cargo-hold signals as the most practical concern. The advice was not that AirTags are dangerous. It was that they may not work the way you expect them to.
