What is the minimum age for a passenger to be considered an infant during flight?

The minimum age for a passenger to be considered an infant during flight is indeed 2 years. In aviation regulations, an infant is typically defined as a child who is under 2 years of age on the date of travel. This classification is important for airlines regarding ticketing and seating arrangements. Infants often do not require a separate seat if they are traveling with an adult and can be held safely on their lap during flight. Once a child reaches their second birthday, they must usually occupy their own seat and may be subject to different fare structures. Understanding this age distinction is critical for compliant travel planning and ensuring the safety and comfort of young passengers.
