The 3-1-1 rule on Lufthansa Airlines is based on international security standards that regulate liquids in hand luggage. Travelers are generally permitted to carry liquids in containers of up to 100 ml (3.4 ounces) each. These items must fit into one transparent quart-sized bag, with one bag allowed per passenger. The rule applies to products such as toothpaste, perfume, shampoo, and lotions. Security officers may ask travelers to remove the bag from their luggage during screening.
