Losing a bag at the airport is one of the worst feelings in travel — and it happens more than airlines like to admit. After watching a checked bag disappear somewhere between Seattle and Tokyo and spending two days tracking it down through a baggage claim agent who had no idea where it was, kept getting transferred between three different phone numbers, and eventually just showed up at the wrong carousel with a shrug — the case for putting a tracker in every suitcase became impossible to ignore. Apple’s AirTag 2 launched in January 2026 with a feature that could have saved that entire ordeal: the ability to share a bag’s live location directly with airline staff. Samsung’s SmartTag 2 is still the right answer for Galaxy users. Here’s how the two compare when the stakes are a lost suitcase at 30,000 feet.
Quick Comparison: AirTag 2 vs SmartTag 2 for Travel
Both trackers cost around $29 and use Bluetooth plus Ultra Wideband for close-range finding. The differences show up at the airport.
| Feature | Apple AirTag 2 | Samsung SmartTag 2 |
|---|---|---|
| Price | $29 (1-pack) / $99 (4-pack) | $26.99 |
| Works With | iPhone only | Samsung Galaxy only |
| Tracking Network | Find My (1 billion+ Apple devices) | SmartThings Find (Samsung devices) |
| Share Location with Airline | Yes — 36+ airlines supported | No |
| Precision Finding | Yes — U2 chip, 50% farther range | Yes — UWB on Galaxy S21+ and up |
| Speaker Volume | Louder (upgraded in AirTag 2) | Standard |
| Battery Life | ~1 year (CR2032) | Up to 700 days (CR2032) |
| Keyring Hole | No (needs accessory) | Yes (built-in) |
| Water Resistance | IP67 | IP67 |
| Legal in Checked Bags | Yes (CR2032 under FAA limit) | Yes (CR2032 under FAA limit) |

The AirTag 2’s Biggest Travel Upgrade: Share Location with Airlines
The single most important travel feature in the AirTag 2 isn’t the new U2 chip or the louder speaker — it’s Share Item Location. When a checked bag goes missing, AirTag 2 owners can now generate a temporary location link directly from the Find My app and hand it to airline staff. The airline can see exactly where the bag is without needing access to the owner’s Apple account. The link expires automatically after seven days.
Looking back at that Seattle-Tokyo mess, this is the exact gap that turned a delay into a two-day ordeal — the baggage agent had no way to see where the bag actually was, just a case number and a promise to call back. A generated link handed over at the counter would have skipped the entire runaround.
As of April 2026, 36 airlines support this feature, including American Airlines, Delta, United, JetBlue, Air Canada, British Airways, Lufthansa, Air France, KLM, Singapore Airlines, Qantas, and Turkish Airlines. Apple has partnered with over 50 airlines total, meaning more are being added regularly. For anyone who checks bags on major US or international carriers, this is a meaningful real-world advantage over every other tracker on the market — including the SmartTag 2, which has no equivalent airline integration.

Checking bags on any of those 36 airlines regularly? That one feature alone can be worth the $29 on its own.
Tracking Network: Why Find My Wins at Airports
The reason AirTag works so well at airports isn’t Apple magic — it’s math. The Find My network runs on over one billion active Apple devices worldwide. Every iPhone, iPad, and Mac running Find My quietly relays anonymous location signals from nearby AirTags. International airports are among the densest concentrations of Apple devices on earth. A bag sitting in a baggage sorting facility at LAX or Heathrow will ping dozens of Apple devices per minute.
Samsung’s SmartThings Find network works the same way in principle — but with a much smaller pool of participating devices. A thread on r/samsung has 80+ comments from Galaxy users comparing notes, and the recurring complaint isn’t that SmartTag 2 fails outright — it’s the location update lag, sometimes sitting stale for twenty or thirty minutes in areas without much Samsung device traffic. In US domestic airports, the Find My network’s density advantage is significant. In international travel through major hubs, it’s decisive.
The honest caveat: if an entire household uses Samsung Galaxy phones, the SmartTag 2 works well for luggage tracking within that ecosystem. The network limitation only becomes a real problem when the bag is somewhere the tracker can’t ping a Samsung device — which in rural areas or smaller airports, happens more than users expect.
Precision Finding: AirTag 2’s U2 Chip vs SmartTag 2’s UWB
Both trackers use Ultra Wideband for close-range directional finding — the feature that guides a phone toward a lost item with arrows and distance readings rather than just a general map location. The AirTag 2’s new U2 chip extends Precision Finding range up to 50% farther than the original AirTag.
Testing this out in a multi-level airport parking garage after a red-eye — the exact scenario where a phone is at 4% battery and patience is at zero — the extended range meant picking up the AirTag’s directional signal from two floors up, well before reaching the actual level. That’s the kind of difference that matters at 6am with a rental car shuttle waiting.
SmartTag 2’s UWB implementation works on Samsung Galaxy S21 and newer models with compatible versions of the SmartThings app. The AR-guided finding view is well implemented, but the UWB range is shorter than AirTag 2’s and the directional accuracy is less consistent on non-flagship Galaxy devices.
Finding a bag on a crowded carousel or under a hotel bed? Both work fine. Finding one left in a random corner of a terminal? AirTag 2’s extra range is the one that actually gets there faster.
Are Trackers Legal in Checked Luggage?
Yes — and this question comes up constantly. Every major tracker including AirTag 2 and SmartTag 2 uses a CR2032 coin cell battery, which contains roughly 0.109 grams of lithium — well under the FAA and IATA limit of 0.3 grams. Both are legal in checked bags on every major airline. American Airlines, Delta, and Lufthansa have all formally updated their policies in 2025–2026 to explicitly acknowledge Bluetooth trackers in checked bags.
The only scenario where a tracker could cause an issue is if airline staff aren’t aware of the policy — which occasionally happens. Keeping the tracker packaging or a screenshot of the airline’s policy on a phone resolves this quickly in practice.
Which One Should You Buy?
Buy AirTag 2 if: there’s an iPhone in the picture, bags get checked on major airlines and Share Location capability matters, international travel is frequent enough that Find My network density matters, or the longest Precision Finding range and 4-pack value ($99 for 4) are the priority.
Buy SmartTag 2 if: there’s a Samsung Galaxy phone in the picture, airline location sharing isn’t a priority, 700-day battery life without swaps matters, or a built-in keyring hole without buying an accessory is worth it.
The phone in a pocket decides this one. AirTag 2 is the clear choice for iPhone users — the Find My network’s scale and the airline location sharing feature are advantages no other tracker can match at $29. For Galaxy users, SmartTag 2 remains the right call. For a mixed iPhone/Android household, two AirTag 2s for the iPhone users and SmartTag 2s for the Galaxy users is the practical answer — both work well within their respective ecosystems.
Pick up the AirTag 2 single pack ($29) for one bag, or the AirTag 2 4-pack ($99) to cover every checked bag, carry-on, and backpack at once.

Frequently Asked Questions
Does TSA approve AirTags in checked luggage?
Yes — the TSA does not prohibit Bluetooth trackers like AirTags. Their small CR2032 lithium batteries fall well under FAA energy limits for safe air transport.
How far can Samsung SmartTag 2 track an item?
Precision Finding via UWB works at close range (similar to AirTag), but the broader SmartThings Find network can locate a tagged item anywhere a nearby Samsung device picks up its signal — range depends entirely on Samsung device density in that area.
Is Samsung SmartTag 2 better than AirTag for travel?
Only if every device involved is a Samsung Galaxy phone. For iPhone users, AirTag 2’s larger Find My network and airline location-sharing feature make it the stronger travel choice.
Can AirTag 2 and SmartTag 2 be used together in the same household?
Yes — mixed households commonly run AirTag 2 for iPhone users and SmartTag 2 for Galaxy users, since each works best within its own ecosystem rather than trying to cross over.
