The Transportation Security Administration of the Department of Homeland Security allows each passenger to carry on a sealed, quart-sized plastic bag of liquids in containers of 3.4 ounces or less on flights operated by Delta or any other airline. If the liquids are drugs or sustenance for babies or youngsters, the TSA makes an exception and allows bigger volumes. If the liquids are not harmful or restricted, passengers can bring larger quantities of liquids in their checked baggage.
Mouthwash, shampoo, liquid soap, lotions, and gels are examples of carry-on liquids that must be contained in containers of 3.4 ounces or less. The size limit does not apply to over-the-counter or prescription drugs. Breast milk, formula, juice, baby food, and teething supplies are among liquid commodities that are exempt for children. Any liquid products that are not exempt from security screening may be subjected to additional scrutiny. Passengers can purchase larger liquid items, such as bottled water, at duty free shops after passing through security checkpoints and entering the airport.
The amount of liquids passengers can bring in their checked luggage is unrestricted. They cannot, however, bring anything on the TSA’s prohibited items list. Gel paints, spray paints, tear gas, gasoline, and other sorts of fuel fall into this category. Chlorine, bleach, and batteries with spillable internal liquids are also included.
