Effective June 1, 2007, and in line with new global security guidelines issued by the International Civil Aviation Organisation, passengers flying on many international airlines will be subjected to restrictions on the carriage of certain items in their hand baggage.

New security screening measures mean all liquids, gels, pastes and aerosols must be placed in re-sealable transparent plastic bags of certain dimensions.

All liquids, gels, pastes and aerosols in containers (eg; tubes, bottles, cans and jars) must each not exceed 100ml. Liquids, gels, pastes and aerosols in excess of 100ml will not be accepted, even if their containers are part-filled.

These items must be placed in a transparent re-sealable plastic bag of a maximum capacity not exceeding 1 litre. These must fit comfortably within the transparent plastic bag, which must be completely closed.

The size of the plastic bag must not exceed 20cm x 20cm (8 inches x 8 inches).

The plastic bag must be presented for visual examination at the airport security screening point. Only one transparent plastic bag per passenger will be permitted to be carried.

Exemptions will be made for medication, for which prescriptions or medical certificates are required. Baby milk and food and special dietary foods are also exempt.

To facilitate screening and to avoid a cluttered X-ray image, transparent plastic bags with 100ml containers must be presented separately from other cabin baggage, coats, jackets and laptop computers for X-ray screening at all screening points.
