What Goes in Checked Luggage vs. Carry-On

Most items are allowed in checked luggage that the TSA (Transportation Security Administration) prohibits in carry-on bags. The key difference: checked bags are screened separately and stored away from the cabin, so hazardous materials and sharp objects that could be used as weapons are permitted below deck. Liquids, gels, and aerosols have no size limit in checked bags—you can pack a full-size shampoo bottle or a quart of peanut butter. Lighters, tools, and certain sporting equipment also move from forbidden to allowed once they go into checked luggage.

However, some items are banned from checked luggage entirely, regardless of how you pack them. These are mostly things that could catch fire or explode in the cargo hold's unpressurized, unmonitored environment. Understanding which category your items fall into prevents delays at the airport and keeps your luggage from being confiscated or your flight from being delayed.

Key Takeaways

  • Liquids, gels, and aerosols of any size are allowed in checked bags, so full-size bottles of shampoo, lotion, and sunscreen pack without restriction.
  • Sharp objects like knives, razors, and scissors are permitted in checked luggage as long as they are sheathed or wrapped to prevent injury to baggage handlers.
  • Tools including hammers, screwdrivers, and drills are allowed in checked bags but prohibited in carry-on bags.
  • Flammable items such as lighters, matches, and aerosol cans with flammable propellant cannot go in checked luggage under any circumstances.
  • Sporting equipment like golf clubs, baseball bats, and ski poles are permitted in checked bags but often require advance notice to your airline.

Liquids, Gels, and Aerosols With No Size Limit

Checked luggage has no liquid restrictions. Pack full-size bottles of shampoo, conditioner, lotion, sunscreen, toothpaste, and cosmetics without measuring or decanting into smaller containers. Peanut butter, honey, jam, and other food spreads are also unrestricted. Perfume, cologne, and essential oils in any quantity are permitted. This is the main advantage of checked bags for travelers who use full-size personal care products or want to bring gifts of food items home.

The only exception: items the TSA classifies as hazardous materials, which have their own rules separate from the liquid restriction. These include certain types of paint, pesticides, and cleaning supplies. Check the TSA website or call your airline if you are unsure whether a specific product is hazardous.

Sharp Objects and Tools When Properly Packed

Knives, razors, scissors, and box cutters are allowed in checked luggage if they are sheathed, wrapped, or otherwise protected so baggage handlers cannot cut themselves. A kitchen knife in a knife roll, a straight razor in its case, or scissors with blade guards all meet this requirement. Do not pack sharp objects loose in your bag or with only a plastic bag around them—wrap them securely in cloth or place them in a hard case.

Tools including hammers, screwdrivers, wrenches, drills, and saws are permitted in checked bags. Power tools with batteries are allowed if the battery is removed and packed separately. Hand tools have no size limit. This makes checked luggage the right choice if you are traveling with tools for a project or moving to a new home. Carry-on bags prohibit all of these items, so checked luggage is your only option.

Sporting Equipment and Recreational Gear

Golf clubs, baseball bats, cricket bats, ski poles, fishing rods, and hockey sticks are all allowed in checked luggage. Tennis rackets, badminton rackets, and squash rackets are permitted. Skis and snowboards can be checked. Most airlines allow one or two pieces of sporting equipment per passenger, though some charge a fee or require advance notice.

Contact your airline before you travel if you are packing expensive or oversized sporting equipment. Some airlines have specific rules about how items must be packed—for example, golf clubs may need to be in a golf travel bag, and skis may need to be in a ski bag. Knowing the airline's requirements ahead of time prevents surprises at check-in and protects your equipment from damage.

Items Banned From Checked Luggage Entirely

Lighters and matches cannot go in checked bags under any circumstances. This includes disposable lighters, refillable lighters, and lighter fluid. Matches—whether book matches, strike-anywhere matches, or safety matches—are also prohibited. These items are fire hazards in the cargo hold and are confiscated if found during screening.

Aerosol cans with flammable propellant (such as spray paint, hair spray with flammable propellant, or insect spray with flammable propellant) are banned from checked luggage. Non-flammable aerosols like some deodorants or air fresheners may be allowed in limited quantities—check with your airline. Batteries, particularly lithium batteries, have strict rules: spare lithium batteries cannot go in checked bags at all and are restricted in carry-on bags as well. Explosives, fireworks, and ammunition are completely prohibited.

Certain medications and medical devices also have restrictions. Syringes with needles are allowed in checked bags if they are capped and accompanied by the medication they are used to inject. Inhalers and EpiPens are permitted. If you travel with prescription medications or medical equipment, pack them in checked luggage only if you also have a copy of the prescription or a letter from your doctor.

Electronics and Batteries in Checked Bags

Laptops, tablets, cameras, and phones are allowed in checked luggage, though most travelers pack these in carry-on bags to avoid damage and theft. If you do pack electronics in checked luggage, remove batteries from devices like cameras or gaming controllers and pack the batteries separately in carry-on luggage. Lithium batteries in devices that are powered on or in standby mode are safer than loose spare batteries.

Power banks and external batteries are restricted. Spare lithium batteries cannot go in checked or carry-on bags. Standard alkaline batteries (AA, AAA, C, D, 9-volt) are allowed in both checked and carry-on bags with no restrictions. If you are traveling with a device that has a non-removable lithium battery, it must stay in your carry-on bag.

Packing Strategies to Avoid Confiscation

Place sharp objects and tools in the center of your bag, surrounded by soft items like clothing, to prevent them from shifting during handling. Wrap knives individually in cloth or place them in a knife roll. Use hard cases for items like golf clubs or fishing rods. Pack heavier items on the bottom of your bag and lighter items on top to prevent crushing.

Keep a list of what you packed in checked luggage, especially if you are traveling internationally. Some countries have their own restrictions on items like certain tools or sporting equipment, and having a record helps you explain what you packed if customs or security has questions. If your bag is opened for inspection, the TSA leaves a notice inside—check it to see what was examined and whether anything was removed.
