Most “checked luggage bans” aren’t checked-bag bans at all. The quiet pattern is an inversion: a bowling ball, a cast-iron skillet, and a snow globe over 3.4 ounces are each barred from the cabin but generally fine in the hold.
Only a short list is barred from the hold outright — fuel-powered curling irons and replica grenades among them. Get it wrong at a U.S. checkpoint and the bill can approach $15,000, plus a five-year TSA PreCheck suspension.
Two separate authorities decide what travels in a checked bag, and they rarely coordinate. Security screening — the TSA in the United States — decides whether an item clears the checkpoint at all and whether it rides in the cabin or the hold.
The airline then applies its own weight, size, and dangerous-goods rules at check-in. Satisfy federal screening and a carrier can still refuse the bag.
For a Western traveler booking a U.S. departure or connection, the stakes are money, time, and an awkward repack at the counter. The hold is not a loophole: some items banned in the cabin are legal below because the risk that grounds the cabin rule does not follow the bag into the cargo hold. But a short list is barred from the hold outright.
The seven categories below come from official TSA guidance and carrier dangerous-goods pages. Battery fire-safety gets its own deep-dives; this piece covers the non-battery surprises.

The categories that surprise people
1. Fuel-powered curling irons
One of the few items barred from the hold outright.
Fire-safety rules prohibit checked luggage from carrying cordless curling irons that run on combustible fuel — and the table in this article shows they are barred from the cabin too. The combustion risk does not disappear just because the bag rides in the cargo hold; it moves somewhere nobody can see it.
2. Replica ordnance
Banned from both the cabin and the hold.
Replica ordnance — hand grenades, mines — is prohibited in both the cabin and checked luggage on every commercial passenger flight. This is a screening rule, not a dangerous-goods nuance: the replica’s only job is to look like the real thing, and screeners cannot tell the difference at luggage speed. It is the rare item the inversion does not apply to.
3. The cabin-banned, hold-legal inversion
Here is the pattern most articles miss. Bowling balls, cast-iron cookware, and snow globes over 3.4 ounces are each barred from the cabin yet generally permitted in checked luggage.
The rationales differ: a bowling ball is an unsuitable cabin object, cast iron could be used as a weapon, and the snow globe trips the cabin liquid threshold. The airline’s weight and size limits still apply to the bowling ball, so it may count against the checked-bag allowance.
| Item or category | Cabin status | Checked-bag status | Why the rules diverge / governing source |
|---|---|---|---|
| Bowling ball | Not permitted | Generally permitted, subject to airline weight and size limits | Security screening treats it as an unsuitable cabin object; the airline still controls checked-bag acceptance. |
| Cast-iron cookware | Not permitted | Permitted | Its cabin restriction concerns weapon-use potential; that cabin rationale does not automatically prohibit checked carriage. |
| Snow globe over 3.4 oz | Not permitted in carry-on | Generally permitted when packed properly | The cabin liquid limit applies at the checkpoint; checked baggage is governed separately. |
| Fuel-powered curling iron | Not permitted | Not permitted | Combustible-fuel styling tools are treated as a checked-baggage fire hazard. |
| Replica hand grenade or mine | Not permitted | Not permitted | Replica ordnance is prohibited in both baggage locations. |
| Brie or camembert over 3.4 oz | Not permitted in carry-on under the liquid rule | Generally permitted | TSA classifies soft cheese as a gel for cabin screening; the checked-bag liquid limit does not apply in the same way. |
| Wrapped gift | Generally permitted | Permitted, but it may be opened for screening | Wrapping can obscure the contents or interfere with X-ray examination, so screening access overrides the presentation. |
| Personal-care or medicinal aerosol | Carrier-specific | Often permitted within applicable quantity and packaging limits | Air New Zealand distinguishes medicinal and toiletry aerosols from others; the retrieved source establishes no universal US rule for every product. |
| Small-arms ammunition | Not permitted in cabin | Conditionally permitted by listed carriers | Cathay Pacific, Qantas, Singapore Airlines, and Air New Zealand impose carrier-specific quantity, packaging, projectile, or licensing conditions. |

4. Brie and camembert
The TSA classifies brie and camembert as gels for cabin screening, so the 3.4-ounce limit applies in hand luggage. Checked bags don’t face the same liquid threshold, so the cheese generally travels fine in the hold. It’s a classification quirk, not a ban — and it catches first-time Europe travelers who packed a picnic.
5. Wrapped gifts
Wrapped presents are permitted in checked bags, with one catch: if the contents are obscured or set off an X-ray alarm, TSA screeners can open the gift. The wrapping survives only if the contents screen cleanly. Pack the gift in a way that survives unwrapping, or leave it unwrapped and bring paper separately.
6. Aerosols
Air New Zealand‘s dangerous-goods guidance splits aerosols in two. Toiletry and medicinal products are allowed in a checked bag; anything outside those two categories is refused.
That split is the clearest source on the personal-care versus industrial distinction, but it is one carrier’s rulebook rather than a blanket TSA or FAA mandate. Treat the distinction as real and carrier-specific, not universal.
7. Ammunition
Asia-Pacific carriers draw their own lines. Cathay Pacific, Qantas, and Singapore Airlines each allow personal-use ammunition up to 5 kg gross, with their own packaging conditions. Air New Zealand requires a current firearms licence, and Singapore Airlines refuses explosive or incendiary projectiles.
The Federal Register cites 49 CFR 175.10(a)(8) as the controlling hazardous-material provision for checked small-arms ammunition. No official page retrieved for this piece set out an equivalent rule for ordinary tools, so that comparison stays open.

How we picked
These categories were verified against official TSA guidance and dangerous-goods pages from Air New Zealand, Cathay Pacific, Qantas, and Singapore Airlines. Where a rule comes from only one carrier — the aerosol split, for example — the piece says so instead of presenting it as universal. Rules and policies confirmed as of September 24, 2026.
What this means for you
Check the carrier’s dangerous-goods page before you pack. Federal screening sets a floor, but the airline operating the flight can still refuse an item at check-in — and the two layers don’t always match.
If a prohibited item shows up, TSA firearm guidance says officers may call local law enforcement, who may arrest or cite the passenger, while TSA itself may levy a civil penalty. That double track — criminal and civil — is the part most travelers don’t see coming.
Key terms
- TSA
- The Transportation Security Administration is the U.S. federal agency that screens passengers and their baggage at airport security checkpoints. It sets the rules for what may pass screening and whether an item belongs in the cabin or the hold, a federal layer that applies before any airline’s own acceptance policy. In this article, that makes the checkpoint the first gate a bowling ball, a snow globe, or a wrapped gift has to clear, whatever carrier is operating the flight.
- Dangerous goods
- Dangerous goods is the catch-all term for items that carriers restrict or refuse in baggage because of fire, explosion, or other hazards in flight. The conditions attached to them — quantity, packaging, licensing, and declaration — are set by the airline rather than by the screening agency. That is how one carrier can split medicinal and toiletry aerosols from all other aerosols while another handles the same category differently.
- Replica ordnance
- Replica ordnance is the screening category for objects built to look like weapons or explosives, such as hand grenades and mines. It is refused in both the cabin and checked baggage on commercial passenger flights, with no exception for the hold. Because screeners have to judge bags as they move, a convincing fake is treated exactly like the real thing, which is why it sits outside this article’s cabin-versus-hold pattern.
- 49 CFR 175.10(a)(8)
- 49 CFR 175.10(a)(8) is the provision of U.S. hazardous-materials regulations that governs small-arms ammunition in checked baggage. It is named in the Federal Register interpretive-rule document retrieved for this article, which allows ammunition in a checked bag only when it is securely packed in approved packaging. The section covers how the ammunition is packed, not how much a given airline will agree to carry, which is why the carriers reviewed here layer their own limits on top of it.
Questions? Answers.
What is forbidden in check-in luggage?
Fuel-powered curling irons that run on combustible fuel are barred from the hold. Replica ordnance, including hand grenades and mines, is prohibited in both cabin and checked baggage. Ammunition and firearms are not outright forbidden but travel only under specific conditions set by 49 CFR 175.10(a)(8) and 49 CFR 1540.111(c).
What are you not allowed in your checked bag?
A checked bag cannot contain cordless curling irons powered by combustible fuel, or replica ordnance such as hand grenades and mines. Beyond those, many items banned in the cabin — a bowling ball, cast-iron cookware, a snow globe over 3.4 ounces — are generally fine in the hold. The airline’s own dangerous-goods page can impose additional restrictions.
Can you pack ammunition in checked luggage on Asia-Pacific carriers?
Yes, but only on the carriers’ terms. Cathay Pacific, Qantas, and Singapore Airlines each set a 5 kg gross ceiling for personal-use ammunition and attach their own packaging conditions; Singapore Airlines refuses explosive or incendiary projectiles, and Air New Zealand requires a current firearms licence.
What are the consequences of bringing a firearm to a TSA checkpoint?
A first violation can bring a civil penalty of nearly $15,000 and a five-year suspension of TSA PreCheck eligibility. A second violation can mean permanent PreCheck disqualification on top of further civil penalties. TSA officers may also call local law enforcement, who may arrest or cite the passenger.
Are aerosols allowed in checked baggage?
Air New Zealand expressly distinguishes medicinal and toiletry aerosols as permitted in checked baggage while barring others, so the split is real but carrier-specific. The 3.4-ounce cabin liquid threshold does not govern checked bags in the same way. No retrieved material established a universal U.S. rule for every aerosol product.
