Answer
The minimum age to become a flight attendant is often 18 years old. Some airlines, especially long-haul, full-service or international carriers, set the minimum at 21.
Check the vacancy: The exact age requirement depends on the airline, country of registration and route network. Airlines may also link age requirements to alcohol service rules, visa requirements, hotel policies, working-time rules or insurance requirements.
Age is only one part of eligibility. Applicants must also meet medical fitness, language, passport, background-check, height or reach, swimming and training requirements. Always check the specific airline job advert, because the minimum age can change between airlines in the same region.
There is usually no upper age limit in the same sense, provided the applicant can pass medical, training and operational requirements. Older applicants can be attractive if they bring strong customer service, language skills or leadership experience.
