Essential travel rules
The 3-1-1 liquids rule
Liquids, gels and aerosols in carry-on baggage must be in containers of 3.4 oz (100 ml) or less, packed in one clear, quart-sized plastic bag.
Lithium battery safety
Spare lithium batteries and power banks are strictly prohibited in checked baggage. Carry them in the cabin to prevent cargo fires.
Infant & medical exceptions
Breast milk, formula, baby food and prescription liquid medicine are exempt from the volume limit in carry-on, but you must declare them for manual screening.
What can you bring on a plane? The complete TSA guide for 2026
One of the most common questions travelers type before a flight is “can I bring this on a plane?” — and the answer depends on whether the item goes in your carry-on or your checked bag, and whether it falls under TSA liquid rules, FAA safety regulations or the customs rules of your destination. BringOnPlane answers each of those questions instantly.
Can I bring food through TSA and on a plane?
Yes — food clears TSA screening and travels on board. Solid food moves freely in both carry-on and checked bags: sandwiches, beef jerky, bananas, granola bars, chips, candy, bread, homemade cookies, fresh fruit and eggs. The golden rule: if you can spread it or pour it, it follows the liquids rule. Peanut butter, honey, jam, yoghurt and queso each need a container of 3.4 oz (100 ml) or less in carry-on. Full-size jars belong in checked baggage.
Can I bring a vape or e-cigarette on a plane?
Vapes, e-cigarettes, disposables and vape pens are allowed on board — but only in your carry-on or on your person. The FAA prohibits lithium-battery devices in the cargo hold because of the fire risk. Vape juice and e-liquid follow the TSA 3-1-1 liquids rule in carry-on. Flying abroad with a vape? Countries such as Thailand, Singapore and Australia ban or heavily restrict them, so check local law before you pack.
Can I bring razors, scissors and sharp items in my carry-on?
Disposable razors, cartridge razors and electric razors are all permitted in carry-on. Safety razors are allowed only with the blade removed — loose blades go in checked baggage. Scissors with blades shorter than 4 inches (10 cm) from the pivot, including eyebrow, embroidery and children’s scissors, are permitted in carry-on. Larger scissors, pocket knives, box cutters and utility knives must be checked. Tweezers, nail clippers and nail glue are unrestricted.
Can I bring a power bank, portable charger or lithium batteries on a plane?
Portable chargers and power banks travel in carry-on only — they are prohibited in checked baggage because of the lithium fire risk. Up to 100 Wh no approval is needed; between 100 and 160 Wh the airline must approve them. Standard AA and AAA batteries may go in either bag as long as the terminals are protected. Rechargeable lithium-ion batteries — laptop, camera and spare vape batteries — must stay in carry-on.
What are the TSA liquid rules, and which toiletries can I bring?
The TSA 3-1-1 rule covers every liquid, gel, cream and aerosol in carry-on: each container must hold 3.4 oz (100 ml) or less, all of them inside one clear, quart-sized zip bag, one bag per passenger. That includes toothpaste, shampoo, conditioner, liquid and gel deodorant, cologne, perfume, hairspray, dry shampoo, hair gel, lotion, sunscreen, insect repellent and shaving cream. Solid stick deodorant, bar soap and powders are exempt. Checked baggage has no volume limit for toiletries.
