Key Takeaways
- An AirTag with its battery installed is allowed in checked luggage under FAA rules, but loose CR2032 batteries are not.
- Airlines including Delta, United, American, and Southwest permit AirTags in checked bags, though some require you to notify them in advance.
- The AirTag must remain powered on during flight so it can connect to other Apple devices and relay your luggage location.
- International flights may have different rules depending on the airline and destination country, so check before traveling abroad.
- Turning off the AirTag before packing does not change its legal status — it is the battery installation that matters to regulators.
Why the Battery Matters More Than the Device
The FAA's concern is not the AirTag itself but the lithium battery inside it. Lithium batteries can overheat in the cargo hold, and the agency treats them as a fire risk. A CR2032 coin-cell battery installed in a device is considered safer than a loose battery because the device's circuitry limits the current the battery can deliver. This is why the rule distinguishes between an AirTag (battery installed and contained) and a spare battery (loose and uncontrolled). If you pack an AirTag with a dead or removed battery, you are technically violating the rule because the battery itself becomes a loose item. The battery must stay inside the AirTag for the entire journey. If you want to disable the AirTag temporarily, you cannot remove the battery — you would have to disable notifications in the Find My app instead.What Major Airlines Actually Allow
Delta, United, American Airlines, and Southwest all permit AirTags in checked bags under their current policies, which align with FAA rules. However, policies can change, and some airlines ask passengers to declare tracking devices at check-in. JetBlue and Alaska Airlines have not issued explicit bans either, though their websites do not always mention AirTags by name. The safest approach is to call your airline's baggage department before you travel and say: "I am packing an Apple AirTag with its battery installed in my checked luggage. Is this permitted?" Write down the name of the agent and the date. If the airline says yes, you have confirmation. If they say no or seem uncertain, you can leave the AirTag at home or pack it in your carry-on instead.Carry-On Versus Checked Luggage
An AirTag is always permitted in carry-on luggage because the cabin is pressurized and monitored. There is no fire risk concern in the passenger cabin, so the battery restriction does not explore. If you are nervous about the checked-bag rule or your airline seems hesitant, straightforward keep the AirTag in your personal item or roller bag that you bring onto the plane. The downside is that an AirTag in your carry-on does not help you track your checked luggage. It only helps you find your carry-on if you lose it in the airport or at your destination. For luggage tracking, you need the AirTag in the checked bag.How to Pack an AirTag Safely in Checked Luggage
Place the AirTag in an interior pocket of your checked bag, away from liquids and sharp objects. A small pouch or zippered compartment works well. Make sure the AirTag is powered on before you close your luggage — it needs to stay on throughout the flight so it can connect to nearby Apple devices and send location data to iCloud. Do not wrap the AirTag in plastic or seal it in a way that traps heat. The device is designed to dissipate heat, and checked cargo holds are cold, so overheating is unlikely. However, avoid placing it directly against metal luggage frames or in a position where it could be crushed if your bag is compressed during loading.International Travel and AirTags
Rules vary by country and airline. The European Union, Canada, and Australia have their own aviation authorities with similar but not identical battery restrictions. Some international carriers are more cautious about tracking devices than US airlines are. If you are flying internationally, contact your airline at least 48 hours before departure and ask about their policy on AirTags specifically. Some countries also have privacy or customs concerns about tracking devices, though an AirTag for personal luggage tracking is rarely flagged. If you are traveling to a country with strict data-privacy laws, research whether the Find My service is fully functional there — in some regions, Apple services may be limited.What Happens If Your Airline Says No
If your airline prohibits AirTags in checked bags, you have two options: pack it in your carry-on, or use a different tracking method. Some luggage brands now include built-in GPS trackers that are airline-approved because they use different battery types or are hardwired into the bag. Tile trackers, which use Bluetooth like AirTags, are subject to the same battery rules, so they face the same restrictions. If you decide to pack the AirTag in carry-on instead, it will not track your checked luggage, but it will help you locate your carry-on if it is lost or delayed. This is still useful, just not for the original purpose.Frequently Asked Questions
Will an AirTag work in the cargo hold during flight?
No. The cargo hold is shielded from wireless signals, so the AirTag cannot connect to other devices or send location data while the plane is in the air. It will only work once the plane lands and your luggage is unloaded. At that point, if another Apple device is nearby, the AirTag can relay its location to iCloud.
Can I pack a spare battery for my AirTag in checked luggage?
No. Loose lithium coin-cell batteries are prohibited in checked luggage under FAA rules. The battery must remain installed in the AirTag for the entire journey. If your battery dies, you would need to replace it after you arrive at your destination.
What if my airline has no policy listed on their website?
Call the airline's baggage or customer service line and ask directly. Most major carriers allow AirTags because they follow FAA rules, but it is worth confirming rather than guessing. If the agent is unsure, ask to speak with a supervisor or request the policy in writing.
Does the AirTag need to be on during the entire flight?
Yes. The AirTag must be powered on so it can connect to other Apple devices once your luggage is unloaded. If the battery dies during your trip, the AirTag becomes useless for tracking. Make sure the battery is fresh before you pack.
Can I use an AirTag to track luggage on a flight where I am not the passenger?
Legally, yes, but ethically and practically, no. Tracking someone else's luggage without their knowledge may violate privacy laws in some places. If you are sending luggage ahead or having someone else travel with your bag, tell them the AirTag is there and share access through the Find My app.
