When Apple unveiled its new AirTag tracker, my thoughts immediately went to how useful this button-sized device could be for frequent flyers travelling with checked luggage.
After all, using the AirTag to keep tabs on everyday items ranging from backpacks and suitcases to expensive jackets, an umbrella, purse or your car keys is a given. If you lose it, an AirTag can track it and help you find it again.
But we’ve all stood around airport luggage carousels, waiting for bags to be disgorged from the chute and then make their way along that snaking conveyor belt to wherever we’re standing.
Could Apple’s newest gadget be the hottest travel accessory since noise-cancelling headphones? 
Executive Traveller headed to the airport, AirTagged luggage in tow, to find out.

Apple AirTag 101 

If you’re not up to speed on the Apple AirTag, here’s a quick recap.
The size of a 20c piece and the shape of a coat button, AirTags are wireless gizmos which can be attached to anything you’re likely to temporarily misplace, leave behind or full-on lose.
Powered by a replaceable CR2032 coin battery, each AirTag is constantly broadcasting a silent, sonar-like Bluetooth ping.
(There’s no ‘off’ switch: the AirTag springs to life as soon as you insert the battery, which lasts for a year and alerts you when it’s running low.)If you lose it, an Apple AirTag can help you find it – sometimes with the help of a friendly stranger.If an AirTag is within Bluetooth range of your iPhone, iPad or even Apple laptop or desktop – which usually means the AirTag is somewhere in your house – its location will appear in Apple’s Find My software (which can already be used to locate iPhones, iPads, AirPods and what-not) to help you find it.
In fact, if you’ve got an iPhone 11 or 12 series and are even closer to your missing item (roughly what’s known in Hide and Seek as ‘getting warm’), your iPhone will switch to Precision Finding mode and guide you to the AirTag by accurately reporting both distance and direction.
This relies on Ultra Wideband technology, enabled by these iPhones and the AirTags both containing Apple’s special U1 microchip. It’s dead clever stuff.AirTags are predictably sleek: shiny stainless steel on one side, glossy white (with optional laser engraving) on the other.What if your gear has wandered much further afield?
Any of the billion-plus other devices in Apple’s cloud-based Find My network – other people’s iPhones, iPads etc – can pick up the Bluetooth signal from any nearby AirTag and privately relay its location back to the owner.
Because the Find My software is baked into Apple’s operating systems and usually always active, this happens automatically: Apple is, in effect, crowd-sourcing an ever-vigilant global search party.
You can even flag an AirTagged item as ‘lost’ so that you get a location alert when it surfaces while the AirTag itself can communicate a contact phone number and message to any Apple user or even Android smartphone user (using NFC) who stumbles upon it.Ironically, most AirTag holders cost more than the AirTag itself.AirTags are predictably sleek – shiny stainless steel on one side, glossy white on the other (this surface can be customised with laser-etching) and not outrageously priced, at $45 each or $149 for a pack of four, although if you want to attach the AirTag to something you’ll need a cost-extra key ring, loop strap or holder (starting at $20).
The AirTag goes head-to-head with similar trackers such as Tile and Samsung’s SmartTag, but it’s an obvious choice for anybody already in the Apple ecosystem, and cleverly taps into the massive size of the Apple device market.

Using Apple’s AirTag for airline luggage 

Now let’s get down to the travel-centric nitty-gritty.
You’re off on yet another flight – hopefully a holiday, although it’s probably work – and you decide to attach an Apple AirTag to each checked bag.
Put a new AirTag next to your iPhone and it’s automatically and elegantly paired to your iPhone (and your Apple iCloud account, which is the backbone of the Find My network), just like AirPods.
To describe what the AirTag is tracking, choose from a list of suggested names – each accompanied by a preset icon – or give it a unique name and choose an icon to suit.
(Of course, you can easily change an AirTag’s name and icon if you need to move it from one device to the another.)Setting up your AirTag is an effortless delight.Attach that AirTag to your luggage, head to the airport and drop off your checked bags as usual.
Obvious question #1: the AirTag is continually transmitting little Bluetooth burps, but don’t airlines want Bluetooth gadgets disabled during flight?
Other luggage trackers such as Tile have been doing the same thing for years, while passengers have wireless Bluetooth headphones and earphones, so this is really not an issue. 
Also worth noting: while airlines have banned rechargeable lithium-ion battery packs from checked luggage (including so-called ‘smart luggage’), this doesn’t apply to the tiny single-use lithium CR2023 cells. Besides which, they’re already in millions of Tiles and key fobs sitting in cargo holds.It’s easy to change the name, and icon, of an AirTag.
Putting Apple’s AirTag to the test
Here, then, is the scenario: you step off your flight and head to a carousel that’s already packed with luggage, with more bags being disgorged by the minute.
But this time your bag has had a high-tech upgrade, courtesy of the AirTag dangling from the handle or more subtly snugged into a side pocket.
Instead of trying to peer over and through the crowd, watching for your luggage to appear, you just stand back – maybe even grab a seat – launch your iPhone’s Find My app and wait for your AirTagged bag to make its presence known.Apple AirTag, $49; Apple AirTag Loop, another $45 (or just can slip the AirTag into a pocket inside the bag).Here’s the bad news: having thoroughly tested the AirTag at an airport, we can report this is not what happens. In this scenario, Apple’s AirTag simply doesn’t work.
The first issue is that the AirTag’s live here-I-am tracking isn’t intended for objects that are moving, unless they’re doing so at the most leisurely pace.
And while the average airport luggage belt is no threat to Usain Bolt, it runs too fast for the AirTag’s virtual hand-waving to be properly identified by your iPhone.
(During my AirTag media briefing earlier in the week, Apple had suggested this might be the case: although to its credit the Find My app was aware the luggage was moving.)Sadly, the AirTag can’t track moving objects such as bags on a luggage claim belt.Even with an iPhone 12 to take advantage of Precision Finding, the only time the AirTagged bag appeared on my screen while being carried along the belt was when it was literally right in front of me.
Of course, if you’re standing at the edge of the luggage belt then you’ll see your bag before anything else; and if you’re stuck behind a three-people deep throng of fellow travellers, you may still spy the bag but the iPhone certainly won’t see it.
What about using all that congestion in your favour? While those plane-loads of passengers are catching up with email and texts and social media on their iPhones, can their combined input to Apple’s Find My network at least show if your bag’s on the carousel?
Again, no. Pinpointing very specific locations on the Find My screen relies on Apple Maps, which simply doesn’t drill down to such a granular level, and certainly not deep inside an airport terminal.Everyone with an iPhone can help track your AirTags without knowing it.Where the AirTag works like a travel charm
So does this mean that Apple’s AirTag is a total fail for the frequent flyer? Far from it.
AirTags have a clear application to help find anything you might travel with but also risk leaving behind or losing: your passport wallet, a briefcase or jacket, even the carry case where your noise-cancelling headphones reside when not in use (there’s a reason noise-cancelling cans are among the most numerous items when airports auction off their lost property).
And there are other times when an AirTag will come to the rescue of your checked luggage.
During peak periods, airport staff can move bags from one flight – even if it’s only recently landed – off the luggage belt as bags from another flight pour in. You finally get through the customs and immigration checkpoint, reach the carousel and waste a half-hour waiting to see your bag on the belt before discovering it’s been sitting in that corral over there.
There’s a good chance the Find My app – especially with Precision Finding – could help show where your bag really is, given that it’s stationary rather than on a moving belt.
In our testing, the iPhone 12 identified and gave clear directions to an AirTagged bag almost 10 metres away.Apple’s AirTag Precision Finding, available on the iPhone 11 and 12 series, in action.Likewise, when a large bag checked in for your flight is unexpectedly directed to the oversized baggage office instead of coming out on the luggage belt, an AirTag could save you plenty of time and frustration.
Another example: a colleague recounted how, on arriving on a flight from Los Angeles to Sydney, her bag failed to appear on the belt, and she was eventually told her bag was in fact among many which were not loaded at LAX.
That turned out not be the case – all the bags had made it to Sydney Airport – and a quick check of the Find My app would have shown they were somewhere in the vicinity rather than 12,000km away.
The take-away? While Apple’s AirTags won’t solve all of your baggage belt blues, they’re still going to find a very welcome place in your travel kit.
