Children up to 2 years of age do not have a seat on board, but must travel in the arms of an adult. They therefore benefit from a lower fare and a special baggage allowance for the free transport of their necessities (pram, baby bottles, nappies, etc.) up to a maximum of 5 kg. A child from 2 to 12 years old, although entitled to a reduced fare (approximately 67% of the adult fare) and a baggage allowance equal to that of an adult, is entitled to a seat entirely to himself.
