At 21 years old, you can apply to be a flight attendant with any airline. Minimum age requirements typically apply at the time of training completion, so candidates who will reach an airline's minimum age during training can apply for flight attendant roles. There is no upper age limit for flight attendants.

Yes, you can absolutely become a flight attendant at 48. In 2026, most major airlines have no upper age limit for new hires, and many actively value the "soft skills" and life experience that mature candidates bring to the role. While some international carriers (particularly in Asia or the Middle East) have historically favored younger crews, U.S. and European airlines are strictly bound by age discrimination laws. The primary requirements are physical: you must be able to stand for long periods, lift heavy luggage into overhead bins, and pass a rigorous safety training program that includes swimming and emergency evacuations. Airlines often find that "second-career" flight attendants are more reliable and excel in de-escalating difficult passenger situations. If you have a background in customer service, healthcare, or education, your age can actually be a competitive advantage during the interview process.
