Key Takeaways
- Standard AirTags with CR2032 batteries are permitted in checked luggage by the FAA, but individual airlines may have stricter rules.
- Airlines including United, American, Delta, and Southwest currently allow AirTags in checked bags, though you should confirm with your carrier before traveling.
- AirTags work best when your phone has cellular service or is connected to a network; they do not send GPS coordinates like traditional trackers.
- If your airline bans AirTags, you can place one in a carry-on bag instead, where it will still help you locate your luggage if your bag is delayed.
- AirTags are most useful for finding luggage in your home, at the airport, or in your destination city—not for tracking a bag mid-flight over the ocean.
What the FAA Actually Allows in Checked Bags
The Federal Aviation Administration (FAA) regulates what batteries and electronic devices can fly in checked luggage. AirTags themselves are not on the banned list. The device is a small plastic disc about the size of a large coin, and it contains a CR2032 lithium coin-cell battery—the same type found in watches, calculators, and hearing aids. The FAA permits these batteries in checked bags under specific rules: they must be installed in or attached to a device, and you can carry a reasonable number for personal use.
The restriction exists because loose lithium batteries can overheat and cause fires in the cargo hold. A battery installed inside a device like an AirTag is considered safer because the device's circuitry limits the current. This is why you can pack an AirTag but not a handful of loose CR2032 batteries.
Which Airlines Currently Allow AirTags
Major U.S. carriers have not banned AirTags. United, American Airlines, Delta, and Southwest all permit AirTags in checked luggage as of the most recent public statements. However, "currently allow" is the key phrase—policies can shift without much notice, especially if there is an incident involving a tracking device or a battery-related issue on another airline.
International carriers vary. Some European and Asian airlines have been more cautious about tracking devices in general, viewing them as potential privacy or security concerns. If you are flying internationally, contact your airline directly before packing an AirTag. Do not assume that because a U.S. carrier allows it, your connecting flight will too.
The safest move is to visit your airline's website and search for "AirTag" or "tracking device" in their baggage policy, or call their baggage services line. A five-minute call saves you the frustration of having your AirTag confiscated at the airport.
How AirTags Actually Work—and Their Real Limits
An AirTag is not a GPS tracker. It does not send your location to Apple's servers or to your phone. Instead, it uses Bluetooth to broadcast a signal that other Apple devices nearby can detect. When another iPhone, iPad, or Mac picks up that signal, it reports the AirTag's location back to you through Apple's Find My network—anonymously and encrypted.
This means an AirTag is useful for finding your luggage in a baggage claim area, in your hotel, or somewhere in your destination city where other Apple devices are present. It is not useful for tracking a checked bag over the Atlantic Ocean or across the country in flight. Once your bag is in the cargo hold, no Apple devices are nearby to relay its location, so you will see no updates until the plane lands and ground crew or other travelers with iPhones come near it.
If your bag is lost or delayed, an AirTag can help you locate it once it reaches the ground. If your bag is stolen from a baggage carousel, an AirTag can show you where it went—assuming the thief or someone near them has an Apple device. This is genuinely useful, but it is not real-time tracking of your bag in transit.
Placing an AirTag in Your Checked Bag
If your airline allows it, the best place for an AirTag is in an interior pocket of your checked bag, ideally one that is not when ready visible when the bag is opened. You want it hidden enough that a casual thief would not spot it, but accessible enough that you can retrieve it when you reach your destination. Some travelers slip an AirTag into a shoe or a zippered pouch inside the main compartment.
Do not attach it to the outside of your bag with a keychain or holder. Baggage handlers may remove it, thinking it is a loose item, or it could snag and tear off during handling. An interior pocket keeps it find and out of sight.
Make sure the AirTag is registered to your Apple ID before you pack it. Open the Find My app on your iPhone, tap the Items tab, and confirm the AirTag shows as "Connected." If it does not, the battery may be dead or the AirTag may not be paired. Replace the battery or re-pair the device before you travel.
What to Do If Your Airline Bans AirTags
A small number of airlines have restricted AirTags, usually citing concerns about tracking devices or battery safety. If your carrier bans them from checked bags, you have options. The simplest is to pack the AirTag in your carry-on bag instead. It will not track your checked luggage in flight, but it will still help you locate your bag if it is delayed and sent to baggage services, or if it ends up in the wrong city.
You can also leave the AirTag at home and use your airline's own baggage tracking system. Most major carriers offer a free app or text-based service that sends you updates when your bag is loaded, unloaded, and ready for pickup. This is less precise than an AirTag—you will not know the exact location of your bag—but it covers the basics.
If you travel frequently and your primary airline bans AirTags, consider switching to a carrier that allows them, or ask the airline directly whether they plan to change the policy. Feedback from customers does influence these decisions.
AirTags vs. Other Luggage Tracking Options
AirTags are not the only way to track a checked bag. Tile trackers work similarly to AirTags but use a different network of devices. GPS trackers like those made by Tracki or LandAirSea send real-time location data via cellular or satellite, but they are bulkier, more expensive, and may have battery restrictions that make them unsuitable for checked luggage. Some luggage brands now include built-in tracking systems, though these vary in reliability.
For most travelers, an AirTag is the simplest and cheapest option if your airline allows it. It costs about $30, requires no subscription, and works seamlessly with an iPhone. The trade-off is that it only works when other Apple devices are nearby—which is usually fine for the scenarios where you actually need it.
Frequently Asked Questions
Will an AirTag work if I fly internationally?
Yes, as long as your phone has cellular service or Wi-Fi at your destination. The Find My network operates in most countries where Apple devices are common. However, if you travel to a country with very few Apple users, the AirTag may not report its location because there are not enough devices nearby to detect it. Check Apple's coverage map before you travel.
Can the airline remove my AirTag from my checked bag?
Yes. If baggage handlers discover an AirTag during handling or screening, they may remove it and discard it. This is rare but possible. Packing it in an interior pocket and registering it to your name reduces the chance of removal, but does not eliminate it.
Do I need to turn off my AirTag before flying?
No. AirTags do not transmit a signal strong enough to interfere with aircraft systems. The FAA does not require you to disable them. You can leave it on and paired to your phone throughout your trip.
What if my AirTag battery dies during my trip?
A CR2032 battery lasts about one year of normal use. If it dies mid-trip, you can replace it with a new CR2032 from any pharmacy, grocery store, or electronics retailer. The AirTag itself is reusable—you just swap out the battery. Keep a spare battery in your carry-on if you travel frequently.
Can I use an AirTag if I have an Android phone?
No. AirTags only work with Apple devices. If you use Android, you cannot see the location of an AirTag on your phone. You would need a Tile tracker or another Android-compatible option instead.
