Only limited quantities of liquids may be carried through security control as hand baggage.
This includes bottled drinks, suntan lotion, fragrances, cosmetics and toiletries.
The following restrictions apply to all liquids, creams, gels, pastes and aerosols taken through security control.
• Liquid items may only be carried in containers holding up to 100ml.
• They must be carried separately in a single transparent, resealable plastic bag.
• The bag must be no larger than 20cm x 20cm (8in x 8in) and all items must fit inside so that it closes properly.
• At security control the bag must be placed separately on the conveyor belt for screening.
• Liquid items larger than 100ml should be packed in your hold luggage – otherwise they will be confiscated.
Exceptions to the 100ml rule can be made for baby food or milk. However, you should only carry what you need for the flight, and you may be asked to taste these items at security control.
Exceptions may also be made for medicines. However, you may be asked to taste any liquid medicines, or to provide evidence (such as a doctor's letter) that you need them for your journey
