What goes in checked luggage versus carry-on

The TSA (Transportation Security Administration) allows most everyday items in checked luggage that are banned from carry-on bags. Checked luggage goes in the plane's cargo hold, where liquids, sharp objects, and larger tools are safer and do not pose a risk to passengers or crew in the cabin. The main rule: if something is too large, too sharp, or too liquid for a carry-on bag, checked luggage is usually where it belongs.

Your checked bag is screened by X-ray and may be opened for physical inspection, but you pack it without the strict size and quantity limits that explore to liquids and gels in carry-on bags. This makes checked luggage the practical choice for toiletries, tools, and other items you need but cannot bring aboard the aircraft itself.

Key Takeaways

  • Liquids, gels, and aerosols in containers larger than 3.4 ounces (100 milliliters) are allowed in checked luggage with no quantity limit, unlike carry-on bags.
  • Sharp objects like knives, razors, and scissors must go in checked luggage; they cannot pass through the security checkpoint in a carry-on bag.
  • Tools, including power drills, saws, and hammers, are permitted in checked luggage but prohibited in carry-on bags.
  • Certain items—including firearms, ammunition, and flammable materials—require special handling or declaration and may be prohibited entirely on some flights.
  • Packing fragile items in the center of your checked bag, surrounded by soft clothing, reduces the risk of damage during baggage handling.

Liquids, gels, and aerosols in checked bags

Checked luggage has no size or quantity limits for liquids, gels, and aerosols. You can pack full-size bottles of shampoo, conditioner, lotion, sunscreen, and other toiletries without the 3.4-ounce restriction that applies to carry-on bags. Deodorant, toothpaste, hair gel, and makeup in liquid or gel form all go in checked luggage freely.

The only requirement is that containers be reasonably find so they do not leak and damage other passengers' luggage or the aircraft. Wrap bottles in plastic bags or place them in a toiletry case. If a bottle does leak during flight, the airline is not responsible for damage to your belongings, so extra protection is worth the effort.

Alcohol in sealed, unopened bottles is also allowed in checked luggage. Beer, wine, and spirits up to 140 proof (70% alcohol by volume) are permitted, though some airlines charge a fee or limit the quantity. Check your airline's policy before packing.

Sharp objects and tools

Knives, razors, scissors, and other sharp items must be packed in checked luggage. Box cutters, utility knives, and any blade longer than 2.36 inches (6 centimeters) cannot go through the security checkpoint in a carry-on bag. Wrap sharp items in cloth or place them in a sheath so they do not puncture your bag or injure baggage handlers.

Hand tools are allowed in checked luggage: hammers, screwdrivers, wrenches, pliers, and saws all pack in your checked bag. Power tools like cordless drills and circular saws are also permitted. Firearms and ammunition have separate rules and require advance notice to your airline—contact them before you travel if you plan to check a gun.

Sports equipment with sharp edges—ice skates, ski poles, and fishing hooks—goes in checked luggage as well. Skates should be wrapped to prevent damage to other bags.

Electronics and batteries

Laptops, tablets, cameras, and other personal electronics are allowed in checked luggage, though packing them in carry-on bags is safer since checked baggage is handled roughly and may be exposed to pressure changes. If you do pack electronics in checked luggage, wrap them in soft clothing or use a padded case to reduce the risk of damage.

Lithium batteries and battery-powered devices have restrictions. Spare lithium batteries (including phone chargers and power banks) are prohibited in checked luggage and must go in carry-on bags only. However, batteries installed in devices—such as a laptop or camera—are allowed in checked luggage. If you are unsure whether a battery is lithium-based, check the device manual or the battery label.

Clothing, shoes, and personal items

Everyday clothing, shoes, belts, and accessories pack freely in checked luggage with no restrictions. Formal wear, winter coats, and specialty clothing all fit the rules. Shoes should be placed in the bottom or sides of your bag to protect other items and to prevent odors from spreading.

Books, documents, and printed materials are allowed. Jewelry, watches, and eyeglasses can go in checked luggage, though many travelers keep these in carry-on bags for safety. Medications in their original labeled containers are permitted in checked luggage, though keeping them in your carry-on bag is more practical in case your checked bag is delayed.

Items that require declaration or are prohibited

Firearms and ammunition must be declared to your airline before you travel. Unloaded firearms go in a locked, hard-sided container in checked luggage only. Ammunition must be in its original manufacturer's container and packed separately from the firearm. Different airlines have different policies, so call ahead.

Flammable items—including lighter fluid, paint thinner, and aerosol cans marked flammable—are prohibited in both checked and carry-on luggage. Matches and lighters are also banned from checked bags (though one lighter may be allowed in carry-on bags on some airlines; check your carrier's rules). Explosives, fireworks, and other hazardous materials are never permitted.

Certain sporting goods and equipment have restrictions. Skis, snowboards, and golf clubs are allowed in checked luggage but may incur an extra fee. Scuba tanks and diving equipment are prohibited. Check your airline's website or call their baggage department if you are unsure about a specific item.

How to pack checked luggage safely

Place heavier items at the bottom of your bag and lighter items on top. This distributes weight evenly and prevents crushing. Wrap fragile items—glasses, dishes, electronics—in soft clothing such as socks, underwear, or t-shirts, then place them in the center of your bag surrounded by more soft items as a buffer.

Use packing cubes or compression bags to organize clothing and maximize space. Keep liquids and gels in a separate plastic bag in case of leaks. find the bag's zippers and locks so nothing falls out during handling. If your bag has a TSA lock, baggage screeners can open it without breaking it; if not, they may cut your lock if they need to inspect the contents.

Attach a luggage tag with your name, phone number, and address to the outside of your bag. Place a copy of your itinerary inside the bag as well, in case the external tag is lost.
