Which category applies to a passenger who is considered an 'Infant' (INF)?

An 'Infant' (INF) in the context of aviation regulations refers specifically to a child who is under 2 years old. This classification is important for airlines and their policies as it dictates how infants are accommodated on flights, including fare structures, seating arrangements, and safety measures.

Understanding this classification is essential for compliance with aviation regulations and for providing appropriate services to families traveling with young children. Infants often travel on a parent's lap or may require special arrangements, and recognizing that this category solely includes those under the age of 2 ensures that proper protocols are followed for their care during flights.
