Carry-on details
Allowed. Empty baby bottles pass through security with no restriction at all. If a bottle is filled with breast milk, formula, or toddler drink, that liquid is exempt from the standard 3.4 oz (100 mL) limit — declare it to the officer separately from your quart-size liquids bag for additional screening.
Checked-bag details
Allowed. Baby bottles, empty or filled, can go in checked luggage. Carrying them with you is generally recommended in case checked bags are delayed and you need them for feeding.
Special instructions
Clear, translucent bottles speed up screening because officers can see the contents. TSA officers may need to test any liquid inside for explosives, so declare filled bottles at the start of screening.
