An adult is defined as?

• A. A passenger who has reached their 12th birthday
• B. A passenger who has reached their 14th birthday
• C. A passenger who has reached their 13th birthday
• D. An adult is not defined by age in this context

Answer: (C)

In airline procedures, passengers are categorized by age to apply policies consistently. The threshold used here is the 13th birthday—once someone has reached that birthday, they are treated as an adult for safety and service purposes. This means a passenger who has turned 13 is considered an adult for things like briefing expectations, seating and fare rules that depend on age, and unaccompanied-minor protocols. The definition at 13 aligns with how many airlines structure rules, providing a clear cut between younger children and older passengers. Saying an adult is not defined by age, or using a different birth-year threshold, would not fit the policy described here.
