In accordance with European Union regulations, the hand luggage of passengers wishing to board flights must be inspected before they can enter the passenger-only zone or board the flight. All passengers must pass through the metal detectors and may also be subject to random manual searches.

Passengers are forbidden from taking articles that constitute a risk for the health of other passengers, the crew and the safety of the aircraft into the passenger-only zone. These items include:

LIQUIDS

The European Union has adopted new security regulations for the transport of liquids in hand luggage which came into force on 6 November 2006 in all airports of the Community, Norway, Iceland and Switzerland. They shall apply to all passengers departing from European airports, regardless of destination.

The new regulation restricts the quantity of liquids that may be taken through security checkpoints. On the other hand, there is no limit to the liquids that may be bought in those shops situated once past said security checkpoints or on board a plane operated by a European company.

Liquids are only permitted in hand luggage in the following cases:     

• Liquids in individual containers with a capacity of less than 100 ml. These containers must be carried in a transparent plastic bag, that can be sealed and opened and with a capacity of not more than 1 litre. Each passenger is only permitted to carry one such bag (including children).
  
  The contents should fit inside the bag comfortably, and it must be possible to close the bag completely.
  
  Liquids include gels, pastes and lotions and the contents of pressurised containers, for example, tooth paste, hair gel, drinks, soups, perfume, shaving foam, aerosols and other items with similar consistency.
  
• Liquids that have to be used during the flight, whether as a result of medical requirements or special dietary needs, including baby food. When requested to do so, the passenger must demonstrate the authenticity of such liquids.
  
• Liquids bought in shops at European Community airports, when, and only when, the shop is located beyond the security checkpoints. Should you acquire any of the products affected by these regulations, ask the shop personnel for more information about how to transport the liquids you have acquired.
  
• Liquids obtained on board an aircraft belonging to a European Community airline. Should you acquire any of the products affected by these regulations, ask the crew for more information about how to transport the liquids you have acquired.

If you are going to travel with some of the permitted liquids mentioned in the previous points in your hand luggage, you must remove them from your hand luggage at the security checkpoints so that they can be inspected separately from the rest of your hand luggage.

These restrictions relating to the transport of liquids do not affect luggage that is checked in..
