Flight Security Specialist Question:

Yes, but only in limited amounts. Liquids and gels must be in individual containers of 3.4 ounces (100 milliliters) or less and placed inside one clear, quart-size, plastic, zip-top bag (such as this option from Ziploc). The TSA emphasizes that containers should fit comfortably into your bag and that only one bag is permitted per passenger. If you need to bring more than 3.4 ounces of any liquid or gel substance, it should go into your checked luggage or be shipped ahead.
