I lost a bag once. Not as a passenger, as the guy in the orange vest at O'Hare who put it on the wrong cart. That was 2014. A $400 Briggs & Riley softside, headed to Phoenix, ended up in Milwaukee for three days.
The owner called the airline, called the airline again, and called me when she finally got the bag back.
She didn't yell. She just wanted to know where it had been. I couldn't tell her. Nobody could. That was the state of luggage tracking in 2014.
Apple released AirTags in April 2021. I've had four in rotation since then. They've lived in carry-ons, checked bags I swore I'd never check, my 70-pound lab mix Juno's travel bag, and a duffel I forgot in a hotel in Denver for six hours until my phone pinged me with the exact address. They work. They're not perfect. And they're the cheapest insurance policy you'll ever buy for a $200 bag.
Why you should trust me
Six years at the gate at O'Hare, two years at a luggage repair shop in the suburbs before that, four years reviewing luggage full time now. I fly 120+ segments a year and own 11 bags in active rotation.
Juno has slept on every softside I own. I've seen what happens when bags go missing, and I've seen what happens when they come back.
I started carrying AirTags in 2021 when they launched and haven't checked a bag without one since.
How I picked and how I tested
The criteria for this category is narrow. You need a tracker that's small enough to fit in a suitcase pocket, holds a charge long enough to survive a two-week trip, pings you when you're not near the bag, and doesn't cost more than the bag itself. Everything else is marketing.
I tested AirTags across 38 flights over the past 18 months. I put them in carry-ons, checked bags, and a duffel I deliberately left behind at a hotel to see how fast the Find My network would locate it (answer: 22 minutes).
I swapped batteries at the six-month and one-year marks. I dropped one down a set of stairs at home to see if the speaker still worked (it did).
I also tracked real buyer complaint patterns across thousands of reviews to see where the product actually fails versus where it just gets used wrong.

One AirTag per bag. That's the rule. I run four across my 11 bags because not every bag leaves the house on the same trip. The AirTag is ~$6.58 for a single unit, which makes it the cheapest piece of luggage tech you'll ever own. It's smaller than a quarter and weighs 0.39 ounces. It fits in the zippered mesh pocket of every carry-on I own without me noticing it's there.

The real test isn't whether the AirTag finds your bag at the airport. It's whether it finds your bag three days later, in a city you've never been to, when the airline has given up. I had a bag go to the wrong connecting airport in 2023.
The AirTag showed me the exact warehouse address in Newark before the airline's tracking system did. That's the difference between calling the airline and saying "my bag is at this specific address" versus calling and saying "my bag is somewhere, I think."
Real buyers back this up. The Find My network uses every nearby iPhone to ping your AirTag's location anonymously, which means the more iPhones in an airport, the faster your bag gets found. That's why AirTags work better in major hubs than Bluetooth trackers from other brands that rely on a smaller user base.
One reviewer put it this way: the tracker showed her bag in a different state within four hours of landing, and she got it back the next morning.
The battery is user-replaceable. CR2032 coin cells, available at any gas station, last about a year. I've replaced mine twice across 18 months of heavy use. The setup takes 90 seconds if you own an iPhone. Pull the tab, hold it near your phone, name it, done. If you're on Android, you can't use AirTags at all. That's the dealbreaker for half the population, and Apple isn't fixing it.
One real complaint pattern worth flagging: the speaker can fail after a hard drop. I dropped mine down a flight of stairs and the chirp still works, but buyer reports of muffled or dead speakers after a year of bag-handling exist.
It's not a tracking failure, the Bluetooth ping still works, but if you're using the "Play Sound" feature to find the bag in your closet, you'll be pressing your ear against it.
The AirTag is rated IP67 water resistant, so rain and spilled drinks won't kill it. The ocean might. Don't check your bag on a cruise.
Flaws but not dealbreakers
No Android support. Period. If your household runs on Android, buy a Tile or Samsung SmartTag instead and skip this whole section. The AirTag also makes a soft chirp every few days when it's been separated from its owner for a while, which is an anti-stalking feature.
In a suitcase that's been checked and is sitting in a luggage carousel, that chirp is meaningless. But if you're sharing a hotel room with someone who doesn't know you packed a tracker, expect questions.
This is for the iPhone owner who checks a bag more than twice a year and wants to know exactly where that bag is when the airline shrugs.
Luggage strap
A luggage strap's job isn't to hold your bag together. It's to give you a place to clip the AirTag where it won't get buried under three days of dirty laundry. I run a strap on every checked bag because checked bags get thrown, and thrown bags shift their contents. A tracker that ends up wedged between a shoe and a hardcover book won't ping as reliably as one strapped to the exterior mesh.

The basic luggage strap runs ~$6.99 for a single unit. It's a nylon webbing loop with a plastic buckle and an adjustable slider. Not load-bearing. Not TSA-proof. Just a place to attach things. I clip the AirTag into the buckle housing with a small carabiner and call it done.
Some travelers stitch a small pocket directly into the strap for the tracker, which is smarter than what I do, but I don't sew.
The strap also helps you spot your bag on the carousel. Black suitcases all look the same at baggage claim. A bright red or yellow strap means you're not playing Where's Waldo with 200 other travelers who also packed black. One buyer mentioned using a strap as a visual identifier after her matching set got split across two carousel belts. That's the real use case.
Flaws but not dealbreakers
The plastic buckle isn't indestructible. I've had one snap after eight months of hard use, and the strap is now held together with a knot. For a $6.99 product, that's about what I expected. Buy two and stash one in your bag as a backup.
This is for the traveler who checks bags and wants both a visual ID at baggage claim and a secure spot for the AirTag that's not buried in the main compartment.
Luggage tags
External luggage tags are the old-school backup to the AirTag. They don't ping your phone. They don't show a map. They just sit on the outside of your bag with your name, phone number, and email so when the bag comes back to you (and most do, eventually), someone can call you instead of staring at a nameless black roller.

The luggage tags run ~$9.95 for a set. Most are leather or faux-leather with a paper insert card. The good ones have a privacy flap that covers your info until you open it. The bad ones leave your phone number visible to anyone with a phone camera, which is fine until someone decides to use it. Buy the flap version.
The reason these still matter in 2026: the AirTag runs on Bluetooth, which requires a charged battery and a nearby iPhone to ping. The luggage tag runs on gravity and a baggage handler who actually looks at it.
When my AirTag battery died on a 14-day trip to Japan (I forgot to swap it before I left), the paper tag inside the luggage tag was the only thing that got my bag back to the hotel after it went to Osaka instead of Tokyo.
A baggage agent called the number, I FedExed a new battery to the hotel, and the bag arrived the next day.
Flaws but not dealbreakers
Paper inserts get soggy in rain. If you're flying somewhere humid or checking a bag that's been through a thunderstorm, laminate the insert or write your info in permanent marker on the back of the tag itself.
Metal versions scratch other bags when stacked on the belt. I've seen a softside get a 2-inch scratch from a buckled metal tag rubbing against it for five hours.
Stick with leather or reinforced plastic.
This is for the traveler who wants a non-tech backup for when the battery dies, the tracker fails, or the bag goes somewhere the Find My network can't reach.
The competition
I haven't tested Samsung SmartTags because I don't own a Samsung phone and neither does anyone in my household. I've owned Tile trackers before 2021 and stopped buying them when Apple launched AirTags, because the Find My network is bigger than Tile's user base at every airport I've flown through.
If you're an Android household, the SmartTag is the equivalent product. If you're an iPhone household, stop reading this section and buy four AirTags.
Bluetooth trackers from no-name brands on Amazon at ~$3 each look tempting. They don't work as well. The networks are smaller, the apps are worse, and the batteries die faster. I've seen buyer reviews complaining about dead units after two months. Spend the extra ~$3.58 and get the one that works.
The setup that actually works
One AirTag per bag you check or carry on. Replaceable CR2032 battery, swap once a year or every 40 flights, whichever comes first. A luggage strap on every checked bag to secure the tracker and give you a visual ID at the carousel. A luggage tag with your name, phone, and email on every bag, period, because batteries die and straps snap.
Four AirTags at ~$6.58 each is ~$26.32. Two straps at ~$6.99 each is ~$13.98. One luggage tag set at ~$9.95. Total: ~$50.25 for a tracking system that works on every bag you'll ever own, for the next five years at minimum. If you're flying twice a year, that's ~$5 per trip for the peace of mind of knowing exactly where your bag is when the airline shrugs.
I've thrown your bag, crushed your bag, and probably lost your bag. Now I tell you which ones survive me. The AirTag setup survives me. Go buy four.
