Checked luggage has different rules than carry-on bags

The TSA (Transportation Security Administration) allows far more items in checked bags than in carry-on bags, because checked luggage stays in the cargo hold where you cannot access it during flight. Most everyday items you pack—clothes, shoes, toiletries, tools, sports equipment—are fine in checked bags. The main restrictions involve things that are flammable, explosive, pressurized, or could damage the aircraft or endanger crew.

The key difference: items banned from carry-on bags are often allowed checked, and items allowed in carry-on are always allowed checked. This is because a fire or pressure release in the cargo hold is contained differently than one in the cabin. However, some items are banned from both, and a few are banned from checked bags specifically.

Your airline may have stricter rules than the TSA, so check their website before packing anything unusual. Different airlines handle sports equipment, musical instruments, and oversized items differently.

Key Takeaways

  • Liquids, gels, and pastes over 3.4 ounces are allowed in checked bags but banned from carry-on, so pack full-size toiletries and liquor in your checked luggage.
  • Lighters, matches, and flammable items are banned from both carry-on and checked bags on passenger aircraft.
  • Tools, power tools, and sharp objects are allowed in checked bags but not carry-on, so pack them there if you need them.
  • Batteries, electronics, and lithium items have specific rules—most are fine checked, but some must go carry-on or are banned entirely.
  • Your airline's baggage policy may be stricter than TSA rules, so verify before packing expensive or unusual items.

Toiletries and liquids you can pack checked

Full-size bottles of shampoo, conditioner, lotion, toothpaste, and other toiletries go in checked bags. The TSA's 3.4-ounce limit applies only to carry-on bags. In checked luggage, you can pack a 16-ounce bottle of shampoo or a full liter of cologne without restriction.

Alcohol under 140 proof (70% ABV) is allowed in checked bags in quantities up to 5 liters per passenger. Alcohol over 140 proof is banned from both carry-on and checked bags. Pack bottles upright or in a sealed plastic bag to prevent leaks from damaging other items.

Medications in liquid or gel form (like inhalers or liquid vitamins) are allowed in checked bags without the 3.4-ounce limit. Keep them in their original labeled containers so TSA can identify them if the bag is inspected.

Tools, sharp objects, and sporting equipment

Tools are allowed in checked bags: hammers, screwdrivers, wrenches, saws, and power drills all go through. Axes, hatchets, and ice axes are also permitted. These items are completely banned from carry-on bags, so checked is your only option if you need them.

Knives of any length are allowed in checked bags but not carry-on. Pack them in a sheath or wrapped securely so they cannot puncture the bag or injure baggage handlers. Razors and razor blades are allowed checked; disposable razors are fine carry-on, but razor blades alone are not.

Sports equipment rules vary by item. Golf clubs, baseball bats, hockey sticks, and ski poles are allowed checked. Firearms and ammunition have strict rules—ammunition is banned from carry-on and checked bags on passenger aircraft, and firearms must be unloaded, declared to the airline, and packed in a locked hard case in checked luggage only. Martial arts weapons like nunchucks and throwing stars are banned from both.

Electronics and batteries

Laptops, tablets, cameras, and phones are allowed in checked bags, though many travelers pack them carry-on to avoid damage. If you check them, power them down completely and pack them where they will not be crushed.

Lithium batteries have specific rules because they can overheat and catch fire. Spare lithium batteries (the kind in phones and laptops) are banned from checked bags entirely—they must go in carry-on only, in quantities of no more than two spares per passenger. Batteries installed in devices (like a laptop or camera) are fine checked. Lithium batteries in larger devices like power tools follow the same rule: the device can be checked, but spare batteries must be carry-on.

Alkaline batteries (standard AA, AAA, C, D, 9V) are allowed in both carry-on and checked bags in reasonable quantities. Gel batteries and wet-cell batteries are banned from both.

Items banned from all luggage

Some items cannot fly in any bag, checked or carry-on. Lighters and lighter fluid are completely banned—this includes disposable lighters, refillable lighters, and lighter fluid. Matches are also banned, except for one small box of safety matches (the kind that only light on the box) in carry-on only.

Flammable liquids and gases are banned from both: paint thinner, gasoline, propane, aerosol cans with flammable contents, and self-inflating life jackets. Bleach, pesticides, and other corrosive chemicals are also banned. Explosives and fireworks of any kind are banned.

Realistic replicas of firearms or explosives are banned from both carry-on and checked bags. This includes toy guns that look real or novelty items shaped like bombs.

Items that need airline approval or special packing

Some items are allowed but require you to notify the airline or pack them in a specific way. Dry ice (used to keep things frozen) is allowed in checked bags only, in quantities up to 5.5 pounds, and you must tell the airline you are carrying it. Pack it so it can sublimate (turn to gas) safely and does not build pressure in the bag.

Sporting equipment with compressed gas cartridges—like inflatable life jackets or self-inflating seat cushions—must have the cartridge removed before packing. The cartridge itself is banned. Some airlines allow you to pack the cartridge separately in checked luggage if it is new and unused; others ban it entirely. Call your airline before packing.

Musical instruments are allowed in checked bags, though many musicians carry them on to avoid damage. If you check a guitar or violin, pack it in a hard case and notify the airline. Some airlines charge an extra fee or require advance notice.

Packing tips to protect your checked bag

Checked bags are handled roughly, so pack fragile items in the center of your bag surrounded by soft items like clothes. Wrap breakables in socks, underwear, or towels. For liquids, place bottles in a sealed plastic bag in case of leaks, and pack them where they will not shift during handling.

Keep a list of what you packed and take a photo of your bag's contents before checking it. This helps if your bag is lost or damaged. Place your name and phone number inside the bag as well as on the outside tag.

If you are unsure whether something is allowed, contact your airline directly before arriving at the airport. TSA rules are federal, but airlines can be stricter, and it is faster to get a clear answer by phone than to discover a problem at check-in.

Frequently Asked Questions

Can I pack a curling iron or hair straightener in checked luggage?

Yes. Hair styling tools with cords are allowed in checked bags. They are banned from carry-on because they can overheat in an enclosed space, but in checked luggage they are fine. Make sure it is completely cool and unplugged before packing.

Are vape pens and e-cigarettes allowed in checked bags?

Vape pens and e-cigarettes with lithium batteries are banned from checked bags. They must go in carry-on only, in your personal item or carry-on bag, not checked. This is a federal rule for all U.S. flights. The battery poses a fire risk in the cargo hold.

Can I pack a pressure cooker or when ready pot in checked luggage?

Yes, as long as it is clean and completely dry. The TSA allows pressure cookers in checked bags. However, some airlines have additional restrictions, so check your airline's website. If you are flying internationally, the destination country may have different rules.

What about packing a gift-wrapped item in checked luggage?

You can pack gift-wrapped items in checked bags, but TSA may unwrap them during inspection if they need to screen the contents. Pack the gift unwrapped or in a bag so it is straightforward to open and rewrap if needed.

Are there limits on how many checked bags I can pack full of items?

TSA has no limit on the number of items in your checked bags, but your airline limits how many bags you can check and how much they can weigh. Most airlines allow one or two free checked bags per passenger, with weight limits of 50 pounds each. Check your airline's baggage policy for specifics.
