The TSA (Transportation Security Administration) has specific rules about what you can bring in your carry-on and checked bags when traveling by air: Liquids and Alcohol:

• Liquids in carry-on bags must follow the 3-1-1 rule: containers of 3.4 ounces (100 ml) or less, all fitting in one quart-sized clear plastic bag.
• Alcoholic beverages with 24% to 70% alcohol are limited to 5 liters per passenger in checked bags and must be in unopened retail packaging

Food:

• Most solid foods are allowed in carry-on and checked bags, but some restrictions apply depending on the destination country, especially for products of animal origin

Electronics and Batteries:

• Portable chargers and electronic devices are allowed in carry-on bags if batteries are under 100 watt-hours (Wh). Lithium-ion batteries must be in carry-on, not checked bags

Sharp Objects and Tools:

• Sharp objects like knives, box cutters, ice picks are prohibited in carry-on bags but allowed in checked bags.
• Small tools (screwdrivers, wrenches) are allowed in carry-on if under certain size limits; larger tools must go in checked bags

Firearms and Ammunition:

• Firearms are only allowed in checked bags if declared at check-in; not allowed in carry-on.
• Ammunition is allowed in checked bags with packaging restrictions

Prohibited Items:

• Items like mace, pepper spray, fireworks, flammable liquids, and many hazardous materials are not allowed in carry-on or checked bags

Other Notes:

• TSA PreCheck travelers have expedited screening and do not need to remove shoes, laptops, liquids, belts, or light jackets

• Personal items (purse, backpack) are treated the same as carry-on bags regarding prohibited items

For a complete and detailed list of allowed and prohibited items, you can consult the TSA's official "What Can I Bring?" page, which categorizes items by type such as food, medical, sharp objects, and more

. In summary, you can bring most personal items, electronics, and food, but must follow liquid restrictions and cannot bring sharp objects, firearms, or hazardous materials in carry-on bags. Checked bags have more leniency but still have restrictions, especially for dangerous goods. Always check both TSA and destination country regulations before traveling.
