Security measures are tight in airports throughout the world. In all UK airports there are strict rules about what you can and cannot carry in cabin baggage. Hand luggage restrictions include limits on size, shape and contents. The Department for Transport has deemed a maximum size of 56cm x 45cm x 25cm for a combined linear length (length + width + height) of 126cm. Some airlines and charter groups also impose weight limits on cabin luggage varying from 3kg to 23kg (see how a luggage scale can help you accurately weigh your luggage). All hand luggage should be able to fit into one of the aircraft’s overhead lockers or under a seat.
The DfT has allowed airports in the UK to remove the limit of one piece of cabin baggage per person. Hand luggage restrictions now apply to cabin baggage and personal items that can be carried on board, including laptops, briefcases, garment bags, infant supplies and items for the disabled. Items that are too large to fit safely inside the cabin must be checked, but special provisions are possible for musical instruments. It is highly advisable to make the necessary arrangements for musical instruments in advance with the airport and airline. During screening, electrical devises will need to be removed and screened separately.
Limits on the amount of liquid in hand luggage are strictly imposed. Hand luggage restrictions require that any liquids must be in containers no larger than 100ml and stored in a transparent resealable bag. Travellers with young children may be permitted to carry on more than 100ml of milk or baby food but may be asked to taste it in the presence of a security officer. Anyone carrying on essential medical equipment must have supporting documentation of need from a doctor and will be screened separately. Pushchairs, wheelchairs and walkers are usually permitted in the cabin but will be security screened.
Hand luggage restrictions do not allow passengers to carry corkscrews, darts, large scissors, hypodermic syringes (unless required for documented medical purposes), knives and metal cutlery. Pointed or edged weapons and sharp objects, including ice skates, knives of any kind, open razors and blades, drills, drill bits, box cutters and screwdrivers are not allowed on board. Blunt instruments such as baseball bats, golf clubs and hockey sticks are likewise prohibited. Of course, firearms and explosives as well as chemical, toxic and flammable substances are expressly forbidden. The only exception is that a traveller is permitted to carry one small lighter on his person or in his hand luggage
