When packing for a flight, it is important to know what items are allowed in your checked luggage. The TSA website provides a comprehensive list of items that are allowed and prohibited in checked luggage. Here are some general guidelines:

Allowed items in checked luggage:

• Liquids, gels, and aerosols in reasonable quantities for your trip, but you must declare them to security.
• Personal-care products, such as deodorant and hairspray, in aerosol containers.
• Cleavers and chainsaws, as long as they are purged of fuel and the airline permits it.
• Vacuum-sealed meats and hard cheeses, spices, dried goods, packaged snacks, chocolates and candy, bread, coffee beans, and tea.

Prohibited items in checked luggage:

• Aerosols in most cases.
• Any device containing lithium metal or lithium-ion batteries.
• Bug spray.
• Oxygen tanks, SCUBA tanks, butane, propane, and other compressed or flammable gases.
• Hazardous materials, including radioactive materials, poisonous or toxic substances, or anything that could be considered a hazardous material.
• Beverages containing more than 70% alcohol (over 140 proof), including grain alcohol and 151-proof rum.

It is important to note that even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
