Quick answer
Yes. You can pack an AirTag or a similar coin-cell Bluetooth tag in checked luggage and leave it switched on. Cellular GPS trackers with rechargeable lithium-ion batteries above 2.7 watt-hours belong in your carry-on, or they go in the hold completely powered off. If you are still shopping, start with trackers for personal belongings and read the battery line before you read anything else.
You hand your suitcase to an agent and trust a chain of belts, tugs, and handlers to get it right. That chain breaks every day. Plenty of travelers end up watching an empty carousel while their bag sits in another city.
SITA Baggage IT Insights reported 6.9 mishandled bags per 1,000 passengers in 2023, better than the prior year and still millions of bags. The answer is a tracker in the suitcase, and that pulls you straight into federal lithium battery rules: FAA PackSafe caps a tracking device left switched on in checked baggage at 0.3 g of lithium metal or 2.7 Wh of lithium ion.
What Makes This Confusing
- Battery chemistry drives the rule. Screeners treat lithium metal and lithium-ion cells differently. You need your device’s watt-hour rating or lithium content before you pack.
- Powered off means powered off. Sleep and standby do not count for a device in the cargo hold.
- Airlines add their own rules. Carriers set policies stricter than the federal baseline, and foreign carriers enforce theirs their own way.
- Smart bags follow a different policy. A suitcase with a battery built into the shell is governed by smart-bag rules, not tracker rules, and the FAA requires it to travel as a carry-on unless the battery is removed.
- The wrong technology finds nothing. A short-range tag and a cellular tracker behave very differently once your bag leaves the terminal.
The FAA PackSafe Rules for Baggage Trackers
The FAA restricts what batteries ride in the cargo hold because crews cannot reach a fire down there. PackSafe sets two thresholds for tracking devices in checked bags.
A non-rechargeable lithium metal battery must contain no more than 0.3 g of lithium metal. A rechargeable lithium-ion battery must not exceed 2.7 Wh. Stay under the applicable number and the device stays on in the hold.
Apple AirTags and most competing Bluetooth tags run on replaceable CR2032 coin cells. A CR2032 holds roughly 0.1 g of lithium metal, about a third of the limit. Switch it on, zip it into your suitcase, and you are compliant.
TSA Approved GPS Trackers & DOT Hazardous Materials Rules
TSA does not publish an approved-device list for luggage trackers. There is no certification sticker to look for and no brand that is pre-cleared. What screeners apply is the federal hazardous materials standard, so “TSA approved” really means “compliant with the battery rules.”
Devices above the PackSafe thresholds fall under the Department of Transportation hazardous materials rules at 49 CFR 175.10. The requirement is short and strict. Any lithium battery device you check must be completely switched off. Sleep mode does not qualify. Standby does not qualify. Low-power mode does not qualify.
You also have to protect the device from accidental activation and from damage. Do not toss a tracker loose among boot heels and hard-sided kits. Put it in a rigid case or wrap it in clothing so nothing presses the power button in transit.
How Battery Type Decides Where Your Tracker Rides
Lithium metal cells are non-rechargeable. They deliver small amounts of power over months, which is exactly what a Bluetooth proximity tag needs.
Lithium-ion cells are rechargeable. They deliver the current a cellular modem needs to push GPS coordinates to a tower. That workload demands capacity well past the 2.7 Wh ceiling, so an active cellular tracker rarely qualifies for the hold.
Read the spec sheet before you pack. The battery line tells you where the device belongs. Coin cell goes in the suitcase. Rechargeable goes in the carry-on with your laptop and power banks.
Why Cellular GPS Trackers Ride in Your Carry-On
Cellular units report real position anywhere there is coverage, and that capability costs power. Their rechargeable packs run many times the 2.7 Wh ceiling.
The Logistimatics Mobile-200 carries a 6000 mAh battery, runs about 10 days between charges, and reports every 30 seconds while moving over 5G and 4G LTE. The MicroTrack Pocket Tracker carries 2900 mAh, runs up to 3 weeks, and adds Wi-Fi positioning for indoor fixes. Both sit above the checked-bag threshold for an active device, so keep either one in your carry-on for real-time GPS tracking, or power it down completely before it goes in the hold.
Both are cellular, which means both need a plan. Logistimatics charges $12.50 per month billed annually or $19.99 month to month, with no long-term contract. Real-time trackers require a subscription because that is how the device transmits its location over the carrier network.

Airline Policies and International Flights
Federal rules set the floor for domestic flights. Airlines set their own ceilings, and they enforce them at the counter. Read your carrier’s dangerous goods page before you leave for the airport.
International travel adds a second rulebook. The FAA itself notes that international rules may differ from domestic ones, so check with your airline before an international flight. Enforcement also varies by airport and by agent.
Save your airline’s lithium battery policy to your phone or print it. A screenshot settles a question at the counter faster than an argument.
Bluetooth Tags vs Real-Time Cellular GPS: Finding Lost Luggage Fast
Travelers routinely spend time comparing Apple AirTags to cellular GPS trackers before a big trip. The two technologies solve different problems.
Bluetooth tags borrow location from nearby phones, and ultra-wideband narrows the last few feet once you are standing next to the bag. Inside a busy terminal that works well. If your bag sits at carousel 7 instead of carousel 3, the tag pings a passing phone and your app updates.
Cellular trackers report their own position over the carrier network. They do not need a crowd. When a bag ends up in an off-airport warehouse at 2 a.m., a Bluetooth tag goes silent and a cellular unit keeps reporting. That gap is the whole difference between the two categories.
Smart Bags, Hard Shells, and Signal Dead Zones
Three practical problems trip people up more than the regulations do.
The first is the smart bag. If your suitcase has a charging battery built into the shell, the FAA requires the bag to go in the cabin unless the battery is removed, and a removed battery then travels with you as a spare. A removable tracker avoids the whole question. For the devices themselves, see our roundup of the best luggage GPS trackers and our explainer on GPS trackers vs Bluetooth trackers.
The second is the shell itself. An aluminum or heavily reinforced case attenuates both GPS and cellular signal. Position the tracker against an outer-facing pocket or the top of the packed contents rather than buried under a metal frame, and expect slower fixes from a hard-sided bag than a soft one.
The third is dead air. Concrete baggage halls, underground sorting facilities, and long international layovers in buildings with no indoor coverage all produce silent stretches. A cellular tracker stores its breadcrumb trail and uploads it when signal returns, so a gap in the map is usually a gap in coverage, not a lost bag.
Packing Your Devices Before You Leave Home
Sort your electronics at home, not at the check-in counter. Rushed repacking is how small items disappear.
Separate coin-cell tags from rechargeable units. Zip the tags into an internal pocket of the suitcase so they stay put. A TSA-recognized lock lets an agent open your bag without cutting it, which is the point, but it also means anything loose can shift or be left behind during an inspection. Secured in a pocket, a tag survives that.
Put every rechargeable unit, laptop, and power bank in your carry-on. Lithium-ion batteries in the cabin keep you compliant and keep a crew member within reach if a cell fails.
What Should Decide Your Choice
Start with the value of what is in the bag. For clothes and shoes, a compliant coin-cell tag answers the only question that matters: did my bag land here?
For camera bodies, tools, product samples, or medical equipment, proximity tracking falls short. You need a device that reports its own position across cities and transfer hubs, which means a cellular tracker in your carry-on.
What our customers tell us consistently is that the bag worth tracking is never the one full of cheap clothes. It is the one carrying gear that cannot be replaced before Monday morning.
Travel frequency decides the rest. Fly twice a year and a tag is enough. Move high-value gear every month and a cellular unit pays for itself the first time a bag goes missing.
So pick the one that fits your next trip, then pack it where the rules put it. Check the battery capacity on the product page, drop the coin-cell tag in the suitcase, and keep the rechargeable unit in the cabin with you.
Frequently Asked Questions (FAQs)
Are AirTags allowed in checked luggage?
Yes. FAA PackSafe permits small tracking devices in checked bags when the lithium metal battery holds no more than 0.3 g of lithium. The CR2032 coin cell in an AirTag holds roughly 0.1 g, so it stays powered on through the flight.
Are Logistimatics GPS trackers and AirTags TSA approved?
TSA does not maintain an approved-product list for luggage trackers, so no device carries that label. What matters is battery compliance: a coin-cell tag like an AirTag can stay switched on in a checked bag, while a rechargeable cellular tracker such as the Mobile-200 or MicroTrack Pocket Tracker belongs in your carry-on, or in the hold completely powered off. Follow those rules and screeners have no reason to pull the device.
Does a GPS tracker work inside a metal suitcase?
It works, but less reliably. Aluminum shells and metal frames weaken both GPS and cellular signal, which means slower position fixes and occasional missed reports. Place the tracker near an outer pocket or the top of the packed contents rather than under a metal panel.
Can I track my suitcase while the plane is flying?
No. A GPS receiver inside the fuselage cannot see satellites, and a cellular tracker has no tower to reach at altitude. Expect your first update after the aircraft lands and the cargo doors open.
What happens if my GPS tracker battery exceeds the 2.7 Wh limit?
Then it cannot stay powered on in checked luggage. Move it to your carry-on, or switch it off completely and protect it from accidental activation before it goes in the hold.
Do international airlines allow Bluetooth trackers in the cargo hold?
Rules for international flights can differ from US rules, and each airline publishes its own policy. Check with your carrier before you fly, and keep any rechargeable tracker in your carry-on.
