1. 3.4 ounces or less
Remember, liquids and gels must be in 3.4 ounce (100 ml.) or smaller containers. Fortunately, these travel-sized containers come with a variety of lid options. Flip-top lids are ideal for your shampoo, conditioner and body wash, while those with pump tops are perfect for things like hair spray.
2. One clear, 1-quart zip-top bag
It doesn't matter how many 3.4 ounce or smaller containers you have as long as they fit in your clear, 1-quart zip-top bag. Regular food-storage bags work, or for a sturdier option, look for a reusable bag designed especially for travel.
3. One per traveler
Each traveler is allowed one of these clear, 1-quart zip-top bags. Be sure to have your 1-quart bag out and ready to be placed in the screening bin in order to move through security as quickly as possible.
Breast milk, baby formula and medicines are exceptions to the 3.4 ounce or less rule. Be sure to only carry what you need for your flight and declare it to the TSA agent before passing through security.
