In general, checked baggage is expressed in one of two ways.
The "weight concept" defines the amount of baggage entitled by the passenger's ticket in kilos. For example, an economy class passenger may be entitled to 20 kilos of baggage and a business class passenger to 30 kilos.
The "piece concept" defines the number of bags entitled by the passenger's ticket. Generally, two pieces of checked baggage are allowed per passenger, each piece weighing no more than 32 kilos (70 lb) and measuring no more than 158 cm (62 in) adding the dimensions: height + width + length. www.xineurope.com
