Short answer: Keep jewelry in your carry-on or on you, never in checked baggage: the U.S. Department of Transportation says so, and airlines can limit liability for it. Pack each piece separately so nothing scratches or tangles, and keep silver dry and away from rubber bands and wool, which give off the sulfur gases that cause tarnish.

The silver hoops went into a little pouch, the pouch went into the suitcase, and a week later they came out with a yellow-gray film you don't remember them having. Or the pouch didn't come out at all, because the suitcase was the one that took a detour through another airport.
Those are the two ways jewelry goes wrong on a trip, and both are well documented. One is a baggage problem, with numbers from airlines and regulators. The other is chemistry, and the culprits include things you may be packing right next to it.
Part one: keep it out of the checked bag
The U.S. Department of Transportation's consumer guide is blunt. Small valuables, including jewelry, should be carried on your person or in a carry-on, because "the only way to be sure your valuables are not damaged or lost is to keep them with you" [1]. It also notes that airlines may refuse to sell extra liability coverage for jewelry, and that on domestic trips the airline's liability for a lost bag is capped, currently at $4,700 per passenger [1].
How often checked bags go wrong: two measures
U.S. airlines mishandled 0.49 bags per 100 in the first half of 2026, down from 0.52 a year earlier, according to Department of Transportation data reported in September 2026 [2]. Globally, the airline IT provider SITA counted 6.3 mishandled bags per 1,000 passengers in 2024. Of those, 74% were delayed, 18% were damaged or pilfered, and 8% were lost or stolen [3].
The two figures are not directly comparable. The DOT counts per bag checked; SITA counts per passenger, including passengers who checked nothing. Either way, the odds on any one flight are low. The point is the category: nearly one in five mishandled bags in SITA's count involved damage or pilfering, and small, valuable items are what pilfering targets.

Part two: what actually tarnishes silver
The Canadian Conservation Institute, which advises museums on caring for collections, explains that tarnish on silver is silver sulfide. It forms when silver reacts with sulfur-containing gases in the air, mainly hydrogen sulfide, and it forms faster as humidity rises. The institute recommends keeping silver below 50% relative humidity [4].
The counterintuitive part: some of the tarnish comes from what you pack next to it
The same guidance lists household materials that give off tarnishing sulfur gases. They include rubber bands, latex and rubber gloves, rubber o-rings, pencil erasers, and wool and wool felt [4].
That list reads like a packing list. Rubber bands around cables. Wool socks and sweaters in a winter suitcase. Felt jewelry rolls and pouches. Put silver in a closed bag with any of them, carry it through a humid bathroom at the hotel, and you have supplied both halves of the reaction: the sulfur and the moisture.
Rubber bands, rubber o-rings, latex gloves, pencil erasers, wool and wool felt all give them off [4].

Scratches and tangles
Tarnish is chemistry; scratching is mechanics. Harder stones and metals scratch softer ones when they rub together, and chains tangle when they move freely. The fix is separation: one piece per slot or roll, earrings pinned or posted in pairs, chains laid flat or threaded through a straw so they cannot knot. None of this needs research, just a case with enough dividers for what you are bringing.

What to do with this
- Never check jewelry. DOT's advice is to keep it on you or in your carry-on, and airlines can limit or refuse coverage for it [1].
- Pack silver away from rubber and wool. Both give off the sulfur gases that cause tarnish [4].
- Keep it out of the hotel bathroom. Humidity speeds tarnish; a drawer in the bedroom is better than the vanity [4].

Frequently asked questions
Can I pack jewelry in my checked luggage?
You can, but the U.S. Department of Transportation advises against it. Its consumer guide says small valuables such as jewelry should be carried on your person or in a carry-on, and that airlines may refuse to sell extra coverage for jewelry. Domestic liability for a lost bag is capped at $4,700 per passenger.
How do I keep silver jewelry from tarnishing when I travel?
Keep it dry and away from sources of sulfur gases. Museum conservation guidance says tarnish forms when silver reacts with sulfur gases and speeds up as humidity rises, and lists rubber bands, rubber and latex items, and wool and wool felt as sources. Pack silver separately and store it outside the bathroom.
Why did my jewelry tarnish in my suitcase?
Likely a mix of sulfur gases and moisture in a closed space. Rubber bands, wool clothing and felt pouches all give off sulfur-containing gases, according to the Canadian Conservation Institute, and a zipped suitcase holds them next to the metal. Humid hotel bathrooms add the moisture that speeds the reaction.
How do I keep necklaces from tangling when I travel?
Stop them from moving. Lay each chain flat in its own slot or pouch, fasten the clasp, or thread the chain through a drinking straw and close the clasp outside it. Keep chains separate from earrings and rings, which catch on links.
How often do airlines lose checked bags?
Rarely on any single flight. U.S. airlines mishandled 0.49 bags per 100 in the first half of 2026, according to DOT data. Globally, SITA counted 6.3 mishandled bags per 1,000 passengers in 2024; 74% were delayed, 18% damaged or pilfered and 8% lost or stolen.
Should I wear my jewelry through airport security?
That is up to you and the checkpoint. Small everyday pieces often stay on, while larger metal items may need to go in the bin or trigger extra screening. Either way, jewelry stays with you, which is the point. Follow the officer's instructions on the day.
How we sourced this
Baggage figures come from two independent sources that measure differently, one per bag and one per passenger, and we say so. Tarnish chemistry comes from the Canadian Conservation Institute's published guidance for museum collections. The advice on scratching and tangling is general practice, not drawn from a study.
