What is a requirement for transporting LAGs in hand luggage?

Transporting liquids, aerosols, and gels (LAGs) in hand luggage is subject to specific regulations designed to enhance aviation security. The requirement for LAGs to be packed in a transparent plastic bag is crucial because it allows for quick and efficient screening by security personnel. The bag must be resealable, and typically it should not exceed a certain size, such as one liter, allowing passengers to bring multiple small containers without exceeding the limit.

This practice helps to ensure that all LAGs are easily identifiable, thus minimizing the chances of prohibited items being transported in carry-on luggage. The transparency of the bag is essential for security screening, making it straightforward for agents to inspect and verify the contents without having to manually search through individual items in a passenger's bag.
