Security Restrictions

Hand Baggage

The UK Department for Transport has set the maximum size for an item of hand baggage* as 56cm x 45cm x 25cm, including wheels, handles and external pockets. However, some airlines may only allow smaller bags, so the best advice is to check with them first. Airlines may also have their own rules regarding the number of bags you are allowed to take on the aircraft therefore, please check with your airline before you travel.

*One musical instrument can be carried on in its case.

Baby Food and baby milk

Baby food and baby milk When travelling with a baby you’re allowed to take enough baby food, baby milk and sterilised water for the journey. In some cases this will be over 100ml. You can carry breast milk in hand luggage even if you’re not travelling with a baby. You cannot carry frozen breast milk in hand luggage. Individual containers of breast milk must hold no more than 2,000ml. Each container will need to be screened at the security point. Airport staff might need to open the containers to screen the liquids.



For safety reasons, the following items cannot be taken on to an aircraft. Please do not pack them in either hand baggage or hold luggage.

  • Flammable liquids and solids.
  • Oxidisers such as bleaching powders.
  • Organic peroxides.

Liquid Restrictions

Security restrictions also remain in place with regard to taking liquids, gels or pastes through security. If you do not need these items in your hand luggage then please place into your hold baggage.
Passengers may take liquids, gels or pastes on board in their hand luggage provided they meet the following restrictions:

  • The liquid is in a container with a maximum volume of 100ml
  • That all liquid containers, meeting the maximum volume of 100ml, can fit comfortably into a transparent, resealable 1 litre plastic bag.

The plastic bag should be presented separately at the x-ray point.

IMPORTANT:  Liquid medicines, baby milk and related products adequate for the flight can still be taken on board.

These products held in a maximum volume of 100ml MUST be placed within the 1 litre bag. Such products in containers greater than 100ml, but considered necessary for the trip, can be placed in hand luggage BUT will be subject to a separate verification process.

Liquids in containers of more than 100ml capacity can be packed into your checked (hold) baggage.  Bags are available from vending machines within the Airport and cost £1 for 2 bags.

Electronic Devices

Passengers on some routes into and out of the UK may now also be required to show that electronic devices in their hand luggage are powered up or face not being allowed to take the device onto the aircraft.

Passengers flying into or out of the UK are therefore advised to make sure electronic devices being carried in their hand luggage are charged before they travel.

Passengers are advised to check the Department for Transport website for latest information on baggage restrictions, and also with their airline.

Further Passenger Information

  • Pushchairs and walking aids will be x-ray screened.
  • Wheelchairs are permitted but will be thoroughly searched.

Please visit the Department for Transport website for more information on hand baggage rules.

Body Scanners

Belfast International Airport has introduced state-of-the-art, non-invasive body scanning technology in response to new regulations put in place by the UK Department for Transport (DfT). This equipment supports the existing security processes at Northern Ireland’s busiest airport and is designed to make the search process more efficient and less intrusive for passengers travelling through the airport.

The body-scanner can detect a wide range of potential threats to security in a matter of seconds and it will be used alongside the airport’s existing security screening systems.

In line with DfT protocols, passengers will be randomly selected for scanning or on activation of the normal security checks. They will then pass through the scanner which highlights those areas where items that need to be checked out are being carried.

The body-scanning equipment deployed at Belfast International Airport uses latest-generation technology which does not produce an image of the person being scanned. The software processes the scan data automatically and indicates the areas that need to be checked by highlighting them on a generic mannequin diagram. The passenger can see this diagram on the screen when they exit from the scanner.

As no images are created, the personal privacy of passengers is respected and there can be no question of images being stored or retrieved later. The information shown on the generic diagram is deleted after the passenger has been cleared by the security officer.

The scanning equipment in use does not produce xrays, nor does it emit ionising radiation. The “millimetre wave” technology uses radio waves at a power output many times lower than portable personal devices like mobile phones. The UK Government has concluded that the use of this equipment does not pose any risk to health.

Body Scanners and Pregnancy

The body scanner in use at Belfast International Airport uses millimetre wave technology. The “millimetre wave” technology uses radio waves at a power output many times lower than portable personal devices like mobile phones. All the technologies deployed have been assessed by government health and safety regulators and have concluded that there are no unacceptable risks to health.

Body Scanners and Pacemakers

The body scanner in use at Belfast International Airport uses millimetre wave technology. The “millimetre wave” technology uses radio waves at a power output many times lower than portable personal devices like mobile phones. All the technologies deployed have been assessed by government health and safety regulators and have concluded that there are no unacceptable risks to health. Passing through the scanner does not constitute a risk to health for any passenger, including those with pacemakers or internal defibrillators.

As walk through metal detectors are still part of the security process please continue to alert security staff of your pacemaker, as you would normally have done.
