Most everyday items are allowed in checked bags, but liquids, sharp objects, and certain tools have hard limits

The Transportation Security Administration (TSA) permits most clothing, shoes, books, toiletries, and personal electronics in checked luggage. The main restriction is quantity and type: liquids and gels must follow the 3-1-1 rule if they go in carry-on bags, but checked bags allow larger quantities in containers up to 68 ounces each. Sharp objects like knives, razors, and box cutters are banned from carry-on but allowed in checked bags if they are sheathed or securely wrapped. Flammable items, explosives, and certain chemicals are prohibited in both carry-on and checked luggage.

What you can pack depends partly on your airline, since some carriers have stricter rules than TSA allows. Always check your specific airline's baggage policy before packing, because restrictions on batteries, sporting equipment, and musical instruments vary. If you are unsure whether an item is permitted, contact your airline directly rather than showing up at the airport with a prohibited item.

Key Takeaways

  • Checked bags allow larger quantities of liquids and gels than carry-on bags, with containers up to 68 ounces each, as long as the total does not exceed 70 pounds.
  • Sharp objects like kitchen knives, box cutters, and straight razors are allowed in checked luggage if they are sheathed or wrapped securely so they cannot cut baggage handlers.
  • Flammable items, explosives, and pressurized containers like propane or oxygen are never allowed in checked or carry-on bags.
  • Lithium batteries, sporting equipment, and musical instruments have airline-specific rules, so you must verify with your carrier before packing.
  • Checked bags are X-rayed and may be opened for inspection, so pack items you do not mind TSA or airline staff handling.

Liquids, gels, and pastes in checked bags have higher limits than carry-on

Checked luggage allows containers of liquids and gels up to 68 ounces (about 2 liters) each, with no total limit per bag as long as the bag stays within weight restrictions. This means you can pack full-size bottles of shampoo, conditioner, lotion, sunscreen, and toothpaste without the 3.4-ounce carry-on limit. Peanut butter, yogurt, honey, and other thick pastes also count as gels and follow the same rule.

Alcohol is treated as a liquid: spirits, wine, and beer are allowed in checked bags in unopened, retail bottles, but the total alcohol content cannot exceed 70% by volume. Some airlines limit the number of bottles or charge a fee, so check before packing. Perfume, cologne, and other fragrances are permitted as long as they are in find, leak-proof containers.

Pack liquids and gels in a separate plastic bag or use leak-proof bottles to prevent damage to other items if a container breaks during handling. Even though checked bags are less strictly regulated than carry-on, TSA and baggage handlers do not want to deal with spills.

Sharp objects and tools allowed in checked bags only

Kitchen knives, steak knives, box cutters, and straight razors are prohibited in carry-on bags but allowed in checked luggage if they are sheathed or securely wrapped so the blade cannot cut through the bag or injure a handler. Wrap the blade in cardboard, place it in a knife sheath, or use a blade guard. Do not rely on the original packaging alone — if the blade can be accessed without unwrapping, it will be confiscated.

Tools like screwdrivers, hammers, wrenches, and saws are allowed in checked bags. Scissors with blades shorter than 4 inches are allowed in carry-on; longer scissors must go in checked luggage. Nail clippers, tweezers, and safety razors (the kind with replaceable blades) are permitted in carry-on bags.

Sporting equipment with sharp edges — ice skates, ski poles, and fishing hooks — must be sheathed or wrapped. If you are unsure whether your tool or blade meets the wrapping standard, err on the side of extra protection: wrap it twice and label it clearly so TSA does not have to unwrap it to inspect.

Items that are never allowed in checked or carry-on bags

Flammable liquids and gases — including lighter fluid, paint thinner, gasoline, propane, and aerosol cans with flammable propellants — are prohibited in both checked and carry-on bags. Explosives, fireworks, ammunition, and firearms are also banned from passenger luggage entirely. Certain chemicals used in laboratories or manufacturing, such as chlorine, peroxide above 2%, and corrosive substances, cannot be transported by air.

Realistic replicas of firearms or explosives are prohibited because they create security risks at the airport. This includes toy guns that look real, replica grenades, or anything that resembles a weapon. Electronic devices with lithium batteries larger than 100 watt-hours (most laptops and power banks) are restricted or banned depending on the airline and the specific watt-hour rating.

Marijuana and other controlled substances are prohibited in both checked and carry-on bags, even in states where they are legal. TSA does not enforce state marijuana laws, and transporting it across state lines is a federal crime. If you are traveling with medication, keep it in its original labeled container and carry a copy of your prescription or doctor's note.

Electronics, batteries, and chargers in checked luggage

Laptops, tablets, phones, cameras, and most personal electronics are allowed in checked bags, but TSA and airlines recommend keeping them in carry-on bags to prevent damage and theft. If you do pack electronics in checked luggage, remove the batteries if possible and pack them separately in carry-on, since lithium batteries pose a fire risk in the cargo hold.

Lithium-ion batteries (found in phones, laptops, and power banks) are restricted based on watt-hour capacity. Batteries under 100 watt-hours are allowed in checked bags in most cases, but batteries between 100 and 160 watt-hours may require airline approval. Batteries over 160 watt-hours are prohibited. Check your device's battery specifications before packing, and contact your airline if you are unsure.

Power banks and portable chargers are treated as lithium batteries and follow the same rules. Spare batteries must be in carry-on bags, not checked luggage. Chargers without batteries attached are allowed in checked bags with no restrictions.

Sporting equipment and musical instruments

Most sporting equipment — golf clubs, tennis rackets, baseball bats, skis, snowboards, and bicycles — is allowed in checked bags, but airlines often charge an extra fee and may have size or weight limits. Some airlines count sporting equipment as a second checked bag; others charge a flat fee of $50 to $150 depending on the item and destination. Check your airline's policy before packing.

Musical instruments can travel in checked bags, but many musicians prefer carry-on to reduce damage risk. Hard cases offer more protection than soft cases. Airlines have different rules for oversized instruments like cellos or harps — some allow them as checked bags, others require a separate ticket or seat. Contact your airline in advance if you are traveling with a large or valuable instrument.

Sporting equipment with sharp edges — ice skates, ski poles, fishing rods with hooks — must be sheathed or wrapped as described in the sharp objects section. Bats and clubs do not need wrapping but should be packed so they do not shift and damage other luggage.

Clothing, shoes, books, and personal items

Everyday clothing, shoes, socks, underwear, and accessories have no restrictions and can fill your entire checked bag. Books, magazines, documents, and papers are allowed without limit. Toiletries like deodorant, shampoo, conditioner, lotion, and makeup are allowed as long as they follow the liquid and gel rules described earlier.

Jewelry, watches, and accessories are allowed in checked bags, but valuable items are at risk of theft or loss. TSA does not inventory checked bags, so if something goes missing, proving what was inside is difficult. Pack expensive jewelry in carry-on bags instead.

Hair dryers, curling irons, and electric razors are allowed in checked bags. Lighters are prohibited in both checked and carry-on bags, with one exception: a single lighter in a protective case may be allowed in checked luggage on some airlines, but this varies widely. Do not pack lighters unless you have confirmed with your specific airline.

What happens if a prohibited item is found in your checked bag

TSA screens all checked bags with X-ray machines and may open bags for physical inspection. If a prohibited item is found, TSA will remove it and may leave a notice in your bag. You will not be charged or fined for a single prohibited item, but the item will not be returned or forwarded to your destination.

If TSA suspects you knowingly packed a prohibited item — particularly weapons, explosives, or large quantities of flammable materials — they may refer the matter to law enforcement. In most cases, a single prohibited item is straightforward confiscated and discarded. If you realize you packed something prohibited after checking your bag, contact your airline when ready; some will allow you to retrieve and remove the item before the flight departs.

Checked bags may also be inspected by your airline's staff or by customs if you are traveling internationally. Keep your bag unlocked or use a TSA-approved lock so inspectors can open it without damaging the bag. If you use a regular padlock, TSA will cut it off to inspect the contents.
