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

The TSA (Transportation Security Administration) allows most clothing, shoes, books, toiletries in solid form, and personal electronics in checked luggage. The main restriction is that liquids, gels, and aerosols must follow the same rules as carry-on bags if you want them checked—though checked bags have more generous limits. Prohibited items in checked bags include flammables, explosives, certain batteries, and weapons. The rules vary slightly by airline, so checking your specific carrier's website before packing saves time at the airport.

Your airline's baggage policy also sets limits on weight and size. Most domestic carriers allow one checked bag up to 50 pounds and 62 inches (length + width + height combined), though budget airlines may charge extra or allow smaller bags. International flights often permit two checked bags. Oversized or overweight bags incur fees that can range from $35 to $200 depending on the airline and how far over the limit you go.

Key Takeaways

  • Clothing, shoes, books, solid toiletries, and most personal items pack freely in checked bags without the liquid restrictions that explore to carry-on luggage.
  • Liquids, gels, and aerosols in checked bags must be in containers of 3.4 ounces or smaller, but you can pack multiple containers as long as they fit in your bag.
  • Sharp objects like knives, razors, and scissors are prohibited in checked bags, but tools like screwdrivers and hammers are allowed if they fit the size limit.
  • Lithium batteries, lighters, and flammable items are banned from checked luggage entirely, even in small quantities.
  • Weigh your bag before arriving at the airport—most airlines charge $35 to $200 for bags over 50 pounds on domestic flights.

Clothing, Shoes, and Personal Items You Can Always Pack

Everyday clothing, shoes, belts, hats, and accessories have no restrictions in checked bags. Pack as much as your weight and size limits allow. Formal wear, workout clothes, underwear, socks, and jackets all go in without question. Shoes can be packed in their original boxes or stuffed with socks to save space.

Personal care items in solid or powder form are also unrestricted: deodorant sticks, solid perfume, powder makeup, dry shampoo, and bar soap all pack freely. Sunscreen in solid stick form is allowed, though lotion sunscreen counts as a liquid. Medications in pill or tablet form have no limits, but keep them in their original labeled containers and bring a copy of the prescription if the medication is controlled or unusual-looking.

Liquids, Gels, and Aerosols: The 3.4-Ounce Rule Still Applies

Checked bags allow liquids and gels, but each container must be 3.4 ounces (100 milliliters) or smaller. You can pack multiple containers as long as they individually meet this size limit. This is different from carry-on rules, where all liquids must fit in a single quart-sized bag. In a checked bag, you can distribute them throughout your luggage.

Common liquids that follow this rule include shampoo, conditioner, lotion, liquid soap, toothpaste, mouthwash, perfume, cologne, and liquid makeup. Aerosols like hairspray, deodorant spray, and spray sunscreen also count as liquids for packing purposes. Pack these items in a separate section of your bag or in a toiletry bag to prevent leaks from damaging your clothes. Seal containers with plastic wrap under the cap for extra protection during baggage handling.

Alcohol in checked bags is allowed only if it is between 24 and 70 percent alcohol by volume (ABV), in unopened retail bottles, and limited to one liter per passenger on most airlines. Beer and wine are prohibited in checked bags on most carriers. Check your airline's specific policy before packing any alcohol.

Tools and Sharp Objects: What Is Prohibited and What Is Allowed

Sharp objects like kitchen knives, razors, box cutters, and X-Acto blades are prohibited in checked bags. Scissors with blades longer than 7 inches are also banned. However, tools like screwdrivers, hammers, wrenches, pliers, and saws are allowed in checked bags as long as they fit within your airline's size and weight limits. Pack these items so they do not puncture the bag or injure baggage handlers.

Sporting equipment with sharp edges—such as ice skates, ski poles, and fishing hooks—is allowed in checked bags. Golf clubs, baseball bats, and tennis rackets are also permitted. Firearms are allowed only if they are unloaded, declared to the airline at check-in, and packed in a locked hard-sided container. Ammunition must be in its original manufacturer's container and packed separately from the firearm.

Batteries and Electronics: Lithium Restrictions and Chargers

Lithium batteries and devices containing lithium batteries are heavily restricted in checked bags. Spare lithium-ion batteries (the kind in phones and laptops) are prohibited entirely in checked luggage. However, devices with built-in lithium batteries—such as laptops, phones, tablets, and cameras—are allowed in checked bags on most airlines, though packing them in carry-on luggage is safer in case of damage.

Alkaline batteries (standard AA, AAA, C, D batteries) are allowed in checked bags. Battery chargers and power banks with built-in batteries are allowed in checked bags on most airlines, but check your carrier's policy beforehand. Avoid packing damaged batteries or batteries with exposed terminals, as they pose a fire risk.

Electronics like hair dryers, electric shavers, and curling irons are allowed in checked bags. may support they are completely dry and cool before packing. Laptops and tablets should be powered off and placed where they will not be crushed by heavier items.

Prohibited Items: Flammables, Explosives, and Hazardous Materials

Certain items are banned from checked bags entirely because they are flammable or explosive. These include lighters (even empty ones), matches, lighter fluid, gasoline, paint thinner, nail polish remover, and aerosol cans of flammable products. Fireworks, firecrackers, and any explosive devices are prohibited. Bleach, pesticides, and other corrosive chemicals are also banned.

Self-inflating items like some camping mattresses and certain sports equipment may be restricted due to the chemicals used in inflation. Dry ice is prohibited in both carry-on and checked bags. Marijuana and cannabis products are prohibited in checked bags on all flights, even in states where they are legal, because federal law applies in the air.

If you are unsure whether an item is allowed, check the TSA website's "What Can I Bring?" tool or contact your airline directly. Packing a prohibited item can result in confiscation, fines, or even criminal charges in rare cases.

Weight and Size Limits: Avoiding Overweight Bag Fees

Most domestic airlines allow one checked bag up to 50 pounds and 62 inches in total dimensions (length + width + height). Bags exceeding these limits incur fees starting at $35 for the first overweight bag and increasing for additional bags or greater overages. Some airlines charge $100 or more for bags over 70 pounds. International flights often allow two checked bags at the same weight limit per bag.

Budget airlines like Spirit and Frontier may have stricter limits—sometimes 40 pounds for the first bag—or charge for checked bags altogether. Premium carriers like Delta and United may allow higher weight limits for first-class passengers. Always check your specific airline's baggage policy on their website before packing.

Weigh your bag at home using a bathroom scale or luggage scale before heading to the airport. If it is close to the limit, remove non-essential items or pack them in a carry-on instead. Repacking at the airport is stressful and may result in missing your flight.

Packing Tips to Protect Your Checked Bag Contents

Checked bags are handled roughly during loading and unloading, so pack strategically. Place heavier items at the bottom and lighter items on top. Use packing cubes or compression bags to organize clothing and maximize space. Wrap fragile items like glasses or electronics in clothing for cushioning.

Keep liquids and gels in a separate plastic bag or toiletry pouch to contain leaks. Seal the caps of liquid containers with plastic wrap before closing the lid for extra protection. Place this bag in the center of your suitcase, surrounded by clothing that will absorb any spills.

Use a luggage lock to find your bag, though TSA agents can open locked bags during inspection. If your bag is opened and inspected, the TSA will leave a notice inside. Attach a luggage tag with your name and contact information on the outside and inside your bag in case the external tag is torn off during handling.

Frequently Asked Questions

What happens if my checked bag is overweight?

You will be charged an overweight fee at check-in, typically $35 to $200 depending on how much over the limit your bag is and your airline's policy. Some airlines charge per pound over the limit. Weigh your bag before arriving at the airport to avoid surprises.

Can I pack a multi-tool or pocket knife in checked luggage?
