Airlines mishandle millions of bags a year. Most turn up — but the hours between “it’s not on the belt” and “we’ve located it” are pure, helpless stress. A £25 tracker turns that black hole into a dot on a map. It’s the single cheapest peace-of-mind upgrade in travel, and we won’t check a bag without one.
Why a tracker beats the airline’s own system
Here’s the thing airlines don’t advertise: you’ll usually see your bag’s location before they can tell you. A modern tracker doesn’t rely on its own cellular connection — it borrows the signal of every compatible phone it passes. Your bag moves through an airport full of phones, and each one it passes quietly relays its position back to you.
That’s the whole game, and it’s why the size of the finding network matters more than any other feature.
The pick: Apple AirTag
For anyone in the Apple ecosystem, the Apple AirTag (4-pack) is the easy answer — one for every bag, plus a spare for a laptop bag or a jacket pocket. It rides on the Find My network, which spans hundreds of millions of devices, so it lights up in precisely the crowded places you tend to lose things.
- Setup is one tap next to your iPhone.
- Battery lasts about a year and swaps in seconds (a common coin cell).
- Precision Finding walks you to it in the last few metres once you’re close.
Buy the four-pack, not the single — the per-tag cost drops and you’ll want one in every bag anyway.
The alternatives (and when to pick them)
AirTag isn’t the only option, and it’s genuinely the wrong one for some households:
- Tile — works across both iPhone and Android, which AirTag can’t claim. Smaller finding network, but the cross-platform flexibility wins if your family isn’t all-Apple.
- Samsung Galaxy SmartTag — the AirTag equivalent for Samsung/Android users, riding Samsung’s own network.
- Chipolo — a solid middle ground with versions that work with Apple’s Find My or Google’s network.
The rule of thumb: match the tracker to your phone’s ecosystem. A tracker is only as good as the network it can borrow, and you want yours plugged into the biggest one your phone can reach.
A lost bag isn’t a disaster if you can watch it catch up to you. A tracker just changes the story from panic to patience.
How to actually use it
Drop one deep inside each checked bag before you leave for the airport. Don’t bother with carry-ons — you can see those, and if yours is genuinely cabin-legal (check it against 20 airlines with our free Carry-On Size Checker) it never leaves your side anyway. Then forget about it until the moment the belt stops and your bag hasn’t appeared. Open Find My, and you’ll usually discover it’s simply on the next flight, or still at your origin airport — information you can hand straight to the desk agent to speed up the reunion.

Frequently asked
Do luggage trackers actually work on flights?
Yes. A tracker doesn't need its own signal — it borrows one. Apple's AirTag pings off the hundreds of millions of iPhones in the Find My network, so the moment your checked bag passes anyone with an iPhone (a baggage handler, another passenger), its location updates. That's why travellers consistently see their bag on the map before the airline can even tell them where it is.
Is Apple AirTag or Tile better for luggage?
For most travellers, AirTag — its finding network is vastly larger than Tile's, which matters most in exactly the places you lose a bag: airports and foreign cities. Tile's advantage is that it works across both iPhone and Android; AirTag needs an iPhone to set up and view. If your household is Android, look at Tile or Samsung SmartTag instead.
Are you allowed to put an AirTag in checked luggage?
Yes. Trackers like AirTag use a tiny, non-rechargeable coin battery that airlines and aviation authorities permit in checked bags. There was brief confusion about this in 2023, but carriers confirmed they're allowed. Millions of travellers fly with them.
Where should I put the tracker in my bag?
Tuck it deep in an interior pocket, ideally in a slim case or clipped to something so it doesn't rattle around. You want it hidden (so it isn't removed) but not wrapped in metal, which can weaken the signal. One in each checked bag is the move.
