Yes, thank you.
Flight attendants must ask for blocks of hours, and the system assigns them to them on the basis of seniority. However, the system also includes criteria related to bilingualism requirements. For example, bilingual attendants will have their request processed on a priority basis, until a certain threshold is reached on the number of employees per plane. This threshold may be determined by the size of the aircraft: of the six flight attendants that a given plane should have, two must be bilingual. You will find the exact numbers in the presentation.
