How to Put an AirTag in Your Luggage (and What the Airline Does With It)

Put it inside the bag, deep in the main compartment, not in an outside pocket a handler can reach. Then learn the second half, which almost nobody does: how to hand that location to the airline.

Until recently, knowing where your bag was did not help you get it back. Since 2024 that has changed. Apple's Share Item Location lets you send a live link to an airline, and more than 50 carriers now accept one.

Key Takeaways

• Placement inside the main compartment beats an outside pocket. An outside pocket is reachable, and a tag on a strap is a tag someone can remove.
• Share Item Location generates a link that shows your item on a live map. It expires after seven days and can be stopped by you at any time.
• Apple has partnered with more than 50 airlines. Thirty-six were confirmed as live by January 2026, including Delta, United, British Airways, Lufthansa and Turkish Airlines.
• SITA is building it into WorldTracer, the tracing system used by over 500 airlines and ground handlers at more than 2,800 airports.
• Spare CR2032 batteries are carry-on only under FAA rules, with terminals protected against short circuit. The one inside the tag is not a spare.
• A tracker answers where the bag is. It does not answer whose bag it is, which is still a job for something on the outside with your name on it.

Where Should You Put an AirTag in a Suitcase?

Inside, and as far in as you can reasonably get it.

The reasoning is simple once you separate the two failure modes. A bag goes missing because the airline mishandled it, or because a person took something. Placement only affects the second one, and only in one direction.

• Main compartment, under the clothes. The default, and the right answer for most people. Hard to reach, hard to spot, and the signal still gets out.
• An interior zip pocket or mesh divider. Slightly easier for you to retrieve, still out of casual reach.
• Not an exterior pocket. This is the one people get wrong. An outside pocket is the first place anyone looks and the easiest thing to open unnoticed.
• Not pressed against a metal frame. Dense metal is what interferes with radio, not fabric or leather. Give the tag some clothing around it rather than a hard shell against it.

One thing placement cannot fix: the AirTag reports where it is, not where your bag is. If someone removes the tag, you are tracking the tag. Burying it is what makes those two the same object for longer.

What Changed: The Airline Can Now Use Your Location

This is the part worth understanding, because it is new and it is the reason a tag in a checked bag is more useful than it was two years ago.

Apple introduced Share Item Location in late 2024. You generate a link in the Find My app and send it to the airline. The recipient opens a webpage showing your item on an interactive map, which updates as new locations arrive and carries a timestamp for the most recent one.

The privacy limits are built into the feature rather than left to the airline. Apple states that the shared location is disabled as soon as you are reunited with the item, can be stopped by you at any time, and expires automatically after seven days. Recipients have to authenticate with an Apple Account or a partner email address, and access is limited to a small number of people.

SITA is building the same capability into WorldTracer, the baggage-tracing system used by over 500 airlines and ground handlers at more than 2,800 airports worldwide. That is the layer that turns a one-off favour into a process.

By January 2026, thirty-six carriers were confirmed as accepting shared locations, among them Delta, United, American, British Airways, Lufthansa, Air France, KLM, Qantas, Singapore Airlines, Turkish Airlines and Air Canada. Apple has said it partnered with more than fifty.

It is worth keeping the scale honest. Delta has said that more than 99% of checked items reach their destination as planned. This feature is insurance against an uncommon event, not a fix for a broken system.

How Do You Share the Location With an Airline?

The sequence matters, because the link only helps once there is a case file to attach it to.

1. File the delayed baggage report first. Do it at the airport if you can. You need a reference number before anyone can act on a location.
2. Open Find My, go to Items, and select the tag. Choose the option to share the item's location.
3. Send the link to the airline's baggage team, quoting the reference. Some carriers have a field for it in their form; others take it by email.
4. Stop sharing once the bag is back. Apple disables it automatically when you are reunited, but you can end it yourself at any point.

Two practical notes. Charge nothing, expect nothing instant, and do not treat the map as an invitation to go and collect the bag yourself from a restricted area. The location is evidence for the people with airside access, which is precisely why the airline integration was needed at all.

The Battery Rule Most Travellers Get Wrong

The AirTag's own CR2032 sits inside the device and travels with it. The mistake happens with the spare.

The FAA is explicit. Spare, uninstalled lithium metal and lithium ion batteries must be carried in carry-on baggage only, and the terminals must be protected against short circuit. If a carry-on bag is checked at the gate, the spares have to come out and stay with you in the cabin.

Protecting the terminals is not optional and not difficult. Leave the battery in its retail packaging, tape over the ends, or put it in a small case or pouch. The rule sits in 49 CFR 175.10(a)(18).

So: pack a fresh CR2032 for a long trip, and pack it in the bag that stays with you. If you would rather not think about it mid-trip, change the battery before you fly. We cover how the tag opens and which batteries cause trouble in our guide to AirTag battery replacement.

Why the Outside of the Bag Is a Separate Job

A tracker answers one question well and another not at all.

It tells you where the bag is. It does not tell a baggage handler, a hotel porter or the person who picked up your identical black case by mistake whose bag it is. Those two jobs need two different objects, and confusing them is how people end up with a tracked bag nobody can return.

That is what a tag on the handle is for, and why we make a leather luggage tag separately from the holders. Name, phone, done. It is a low-technology answer to a problem the high-technology one does not address.

Where the two meet is on the outside of a carry-on you keep with you. A holder clipped to a handle is fine on a bag that never leaves your sight, and a poor idea on one that disappears down a belt.

What a Holder Does and Does Not Solve

An AirTag has no attachment hole. Apple did not add one in 2021 and did not add one to the 2026 model either. Everything you want to clip it to needs an intermediate object.

For a tag going loose inside a suitcase, a holder is optional. The bag is the case. What a holder buys you there is a tag you can find in a packed suitcase and a shell that survives being crushed under shoes for a decade.

For a tag on keys, a rucksack strap or a dog collar, a holder is the product, and retention is the whole specification. Our v3.0 uses the keyring itself as the lock, so the tag cannot leave until the ring does. We go through how the different materials fail in the materials comparison.

One honest limitation on ours. Leather is not waterproof and carries no ingress rating of any kind. The tag inside is IP67 rated by Apple to a metre for half an hour, but a soaked leather holder will darken and stiffen, and that is a permanent change to the leather rather than a fault in the tag.

Frequently Asked Questions

Are AirTags allowed in checked luggage?

Airlines are actively building recovery workflows around them, and more than fifty carriers have partnered with Apple to accept shared locations. The rule that catches people out concerns spare batteries, which are carry-on only. Check the FAA PackSafe listing for your own devices before you fly.

Where is the best place to put an AirTag in a suitcase?

Deep in the main compartment, surrounded by soft items, rather than in an exterior pocket. Avoid pressing it flat against a metal frame.

Which airlines accept a shared AirTag location?

Thirty-six were confirmed live in January 2026, including Delta, United, American, British Airways, Lufthansa, KLM, Air France, Qantas, Singapore Airlines and Turkish Airlines. Apple has partnered with more than fifty in total.

Can the airline see my location after the bag is found?

No. Apple disables the shared location once you are reunited with the item, and the link expires after seven days regardless. You can also stop it yourself at any time.

Does a leather holder stop the tag working inside a bag?

No. Leather does not shield the signal. Dense metal is what causes problems, which is why placement matters more than the holder.

Do I still need a luggage tag if I have an AirTag?

Yes, for a different reason. A tracker tells you where a bag is. A tag tells whoever is holding it who to return it to.

The Short Version

Bury the tag in the main compartment, keep spare batteries in the cabin, and know before you travel that the location can now be handed to the airline rather than just stared at.

Thirty-six carriers accept a Share Item Location link today and SITA is putting it into the system 500 airlines already use. That is the change worth acting on, and it costs nothing to learn.

We make leather AirTag holders and luggage tags in our Istanbul workshop, cut from full grain leather. They answer two different halves of the same trip.
