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 (100ml) or less, packed inside a single clear, quart-sized plastic bag.
Lithium battery safety
All spare lithium batteries and portable power banks are strictly prohibited in checked baggage. They must be carried in cabin baggage to prevent cargo fires.
Infant & medical exceptions
Breast milk, baby formula, baby food, and prescription liquid medicines are exempt from volume limits in carry-ons, but you must declare them for manual security screening.
What Can You Bring on a Plane? The Complete TSA Guide for 2026
One of the most common questions travelers type before every flight is "can I bring this on a plane?" — and the answer depends on whether the item is going in your carry-on bag or your checked bag, and whether it falls under TSA liquid rules, FAA safety regulations, or international customs rules. BringOnPlane answers every one of these questions instantly.
Can I Bring Food Through TSA and on a Plane?
Yes — you can bring food on a plane and through TSA security. Solid foods travel freely in both carry-on and checked bags. This includes sandwiches, beef jerky, bananas, granola bars, chips, candy, bread, homemade cookies, fresh fruit, eggs, and even Uncrustables. The golden rule: if you can spread it or pour it, it follows the liquids rule. Peanut butter, honey, jam, jelly, yogurt, and queso must each be in containers of 3.4 oz (100ml) or less if you are packing them in your carry-on bag. Full-size jars belong in your checked baggage.
Can I Bring a Vape, E-Cigarette, or Weed Vape on a Plane?
Vapes, electronic cigarettes, disposable vapes, and vape pens are allowed on planes — but only in your carry-on bag or on your person. The FAA strictly prohibits lithium battery-powered devices in checked cargo holds due to fire risks. Vape juice and e-liquid must follow the TSA 3-1-1 liquids rule in carry-on bags. Traveling internationally with a vape? Note that countries like Thailand, Singapore, and Australia either ban or heavily restrict vapes, so research local laws before you pack.
Can I Bring Razors, Scissors, and Sharp Items in My Carry-On?
Disposable razors, shaving razors, and electric razors are all fully permitted in carry-on bags. Safety razors are allowed carry-on only if the blades are removed — loose blades must go in checked luggage. Scissors with blades shorter than 4 inches from the pivot point (including eyebrow scissors, embroidery scissors, and kids 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 Portable Charger, Power Bank, or Lithium Batteries on a Plane?
Portable chargers and power banks must travel in carry-on bags only — they are prohibited in checked baggage due to lithium fire risk. Power banks up to 100Wh are unrestricted in carry-on; banks between 100–160Wh require airline approval. Standard AA and AAA batteries can go in carry-on or checked bags when terminals are protected. Rechargeable lithium-ion batteries (laptop batteries, camera batteries, spare vape batteries) must be in carry-on bags only.
What Are the TSA Liquid Rules? What Toiletries Can I Bring?
The TSA 3-1-1 rule applies to all liquids, gels, creams, and aerosols in carry-on bags: each container must be 3.4 oz (100ml) or less, all fitting inside a single quart-sized clear zip bag, with one bag allowed per passenger. This covers toothpaste, shampoo, conditioner, liquid deodorant, gel deodorant, cologne, perfume, hairspray, dry shampoo spray, hair gel, lotion, sunscreen, bug spray, and shaving cream. Solid stick deodorant, bar soap, and powder products are exempt from this rule. You may bring any quantity of toiletries in your checked baggage.
