How many liters can you carry onto plane?

Answer 1

3 oz. bottles only (actually 100 ml, which is slightly larger)

Each person is allowed 1 quart sized zip lock bag with toiletry items. Each bottle must be the travel- sized 3.3 oz or less. The containers must be labled with the oz on it. so if you buy the reusable plastic travel containers and there is no size markings they will not be allowed on-board in your carry-on luggage. The zip lock must be sealed and removed from your carry-on and sent through the x-ray separately. if you have medicine you must have a doctors prescription for liquids and gels. health supplements and over the counter medicines should go in checked baggage if over the 3.3 size limits. baby formula and food is allowed but in limited quantities. you must be travelling with the infant it's best to buy the powder milk than purchase bottle water to mix with it AFTER you pass through security. if your child can only drink distilled water, than freeze the baby bottles as most airlines only allow 2 filled bottles of formula on board. Unless you have a doctor's prescription supplements like ensure or pedialight can't go. diabetics should have a doctor's note stating they need to travel with their meds,sugar water or juice. frozen foods can be carried on board as it is now a solid. apple sauce,puddings, canned fruit or meats and other items that contain liquids,gels or creams can't go. if travelling from Another Country, most food items will be confiscated by customs agents. holy water or other liquid religious items that are over the 3.3 size limit should go in checked baggage. if you are bringing back food, water, or dirt from the homeland, it will be confiscated by custom and Immigration. check their website on what can be brought into the usa before you fly here. lghters even empty
