Baby bottles are allowed through security, whether pre-filled or empty
Baby bottles are allowed through security, whether prefilled or empty. This applies to baby bottles from home, as well as sealed and opened bottles. Baby formula, breast milk, toddler drinks, and baby/toddler food (including puree pouches) are considered medically necessary liquids. This means that you can bring more than 3.4 ounces (100 milliliters) of milk or water for your baby, and these do not need to fit in a clear plastic bag.
It is important to note that the rules may vary depending on the country and airport. For example, in the UK, there is no legal limit to how much baby food, baby milk, or sterilized water you can bring on a plane, but individual containers of breast milk must not hold more than 2,000 ml and will need to be screened at the security point.
When bringing baby bottles through security, it is recommended to inform the TSA officer at the beginning of the screening process that you are carrying formula, breast milk, or related supplies. These items should be removed from your carry-on bag to be screened separately from your other belongings. To facilitate the screening process, it is recommended to use clear, translucent bottles instead of plastic bags or pouches. Additionally, consider printing the TSA rule about baby liquids or saving it on your phone in case a TSA agent is unfamiliar with the specific guidelines.
You can also bring water bottles for baby formula through security, and these can be opened or sealed, reusable or plastic. It is recommended to inform the TSA officers that the water is for the baby, and they may test it by hovering a strip over the open bottle.

Medically necessary liquids include formula, breast milk, toddler drinks, and baby/toddler food
When travelling with formula, breast milk, toddler drinks, or baby/toddler food, it is important to inform the TSA officer at the beginning of the screening process. These liquids will need to be screened separately from your other belongings, and officers may need to test them for explosives or prohibited items. It is recommended that these liquids be transported in clear or translucent bottles, as bottles are preferable to plastic bags or pouches for screening purposes.
You can bring packaged drinks or baby bottles (opened or unopened), as well as the baby's personal reusable bottle or cup. In addition to formula and breast milk, baby food jars, purees, pouches, and other baby food and liquids are allowed through security and on the plane for the baby's consumption.
While there is no legal limit to how much formula, breast milk, or baby food you can bring, it is important to bring a "reasonable" amount. The definition of "reasonable" is open to interpretation, but as long as you are not bringing an excessive amount, you should be allowed through security without issue.

Baby formula is not subject to the 3.4-ounce rule that applies to other liquids
When travelling with an infant, you can bring baby formula, breast milk, baby food, and water through airport security. Baby formula is considered a medically necessary liquid by the TSA, meaning it is not subject to the 3.4-ounce (100ml) rule that applies to other liquids.
There is currently no upper limit on how much baby formula or breast milk you can bring on board. However, you should be aware that the rule states you can bring a "reasonable quantity", which is open to interpretation. The amount you can bring will likely depend on the airport and TSA agent you encounter. As long as you are not bringing an excessive amount, you will probably be allowed through.
You can bring packaged drinks or bottles (opened or unopened), or your baby's personal reusable bottle or cup. It is recommended that you remove the drink from your carry-on bag and place it in a separate security bin. Inform the TSA officer that you are carrying formula, breast milk, or toddler drinks in excess of 3.4 ounces. They may need to test the liquids for explosives or prohibited items, so it is helpful if these are stored in clear, translucent bottles.
If you are travelling without a baby, you can bring an empty water bottle through security. You can then fill it up once you have passed through security.

Adults travelling without a baby can only bring empty water bottles through security
If you are an adult travelling without an infant, you are not allowed to bring a water bottle through security unless it is empty. This is because water bottles containing liquid are considered a security risk and can only be brought through security if they are deemed "medically necessary".
Medically necessary liquids include formula, breast milk, toddler drinks, and baby/toddler food (including puree pouches). These items are exempt from the standard liquid restrictions and can be brought through security in quantities greater than 3.4 ounces (100 millilitres). It is recommended that these liquids be transported in clear, translucent bottles rather than opaque containers like plastic bags or pouches, as they may need to be screened using X-ray machines or other methods such as Explosive Trace Detection and Vapor Analysis.
Additionally, ice packs, freezer packs, frozen gel packs, and other cooling accessories are also allowed in carry-ons, even if there is no breast milk or formula present. These items will be subject to the same screening procedures as liquid containers.
It is important to note that while you can bring an empty water bottle through security, you will need to fill it after passing through security and before boarding your flight. Water bottles purchased post-security can be brought on board the plane.
