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, 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 $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.
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.

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. Galaxy-centric users report that SmartTags sometimes don't update frequently enough in real-world travel scenarios, particularly in locations where Samsung device density is lower. 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. In a practical test scenario — a 400-car airport parking garage — that extra range means the phone picks up the signal from two floors away instead of requiring direct proximity.
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.
For finding a bag on a crowded baggage carousel or in a hotel room where it slipped under the bed, both trackers work well. For finding a bag that airline staff left in a remote part of a terminal, AirTag 2's extended range gives it a real edge.
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?
📍 Apple AirTag 2
- You have an iPhone
- You check bags on major airlines and want Share Location capability
- You travel internationally where Find My network density matters
- You want the longest Precision Finding range
- You want 4-pack value — $99 for 4 trackers
📍 Samsung SmartTag 2
- You have a Samsung Galaxy phone
- Airline location sharing isn't a priority
- You want 700-day battery life without worrying about swaps
- You want a built-in keyring hole without buying an accessory
- You're already in the Samsung SmartThings ecosystem
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; there's no Android-compatible tracker with better ecosystem integration at this price. 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. Galaxy users can grab the Samsung Galaxy SmartTag 2 ($26.99) directly.
