Security Screening

Measures for Liquids, Aerosols and Gels (LAGs)

LAGs is the procedure for screening passengers and airline staff traveling in every flight departing from every airport under AOT, including staff and persons who are granted the rights to pass the restricted area behind the security check point in every AOT airport. This measure is not applied to liquids, aerosols and gels (LAGs) or other materials and substances with similar characteristics which are medicines and milk or infant nutritions. Medicines, milk, and infant nutritions in appropriate quantity are permitted to be taken on board.

Personal belongings

  • LAGs must be contained in a container of size not over 100 ml. (Containers over 100 ml. are not permitted to be taken on board, even if it contains less than 100 ml. of LAGs).
  • All containers of LAGs according to 1.1 shall be placed together in a transparent re-sealable plastic bag and shall have overall capacity not exceeding 1,000 ml. (or equivalent in other measurement units). The bag must be sealed and each passenger can take one plastic bag on board.
  • Each passenger shall separate the plastic bag according to 1.2 from other personal items that will be taken on board, including jackets and computer devices, and shall let the officer check it at the security checkpoint.

Measures for Security Screening before Boarding

Passengers and their personal belongings shall be screened in order to search for weapons, dangerous objects or prohibited objects which passengers may take on board. The objective is to prevent weapons or other dangerous objects which may be used for illegal intervention from being taken on board, no matter they are carried without permission or hidden or brought by other methods. This is to provide safety for aviation affairs in compliance with the standard of the International Civil Aviation Organization (ICAO) or other related laws.
