For hand baggage allowed into the airplane, IATA (International Air Transport Association) has set up some regulations. The most important regulations are about maximum dimensions, the weight and the contents of the hand baggage. Sometimes hand baggage allowances are also referred to as hand luggage allowances or carry-on baggage allowances.
For the dimensions of the hand baggage is the formula L + W + H = 110 cm applicable. This means that the length, width and height added together may be 110 cm maximum. A standard size of 55 cm x 35 cm x 20 cm is always allowed on board. But despite the regulations, some airlines use different dimensions, it is not a tough requirement of IATA. British Airways and easyJet for example allow dimensions of 56 cm x 45 cm x 25 cm.
Even when it comes to the weight of hand luggage every airline has its own regulations. To avoid problems at the airport, it is advised to check the regulations of the airline before departure. Most common are the weights between 8 kilo and 12 kilo.
It is strictly forbidden to carry dangerous fluids and goods in your hand baggage. It is forbidden to bring knives, weapons and firearms on board. Sharp objects in hand luggage will be refused to take on board. Put sharp objects like nail scissors, a nail file or pocket knife in your checked baggage to avoid problems. Next to this are fluids, gels and sprays only allowed in small amounts. Before departure, please check the hand luggage liquid restrictions.
