A high school diploma is generally required to enter the field. While each airline has specific requirements, in general, candidates should be in excellent health, able to speak clearly, and be willing to relocate. Travel experience, customer service skills, and speaking a foreign language would all be an advantage. Candidates could expect several weeks of concentrated training and many months of serving as a substitute attendant before working full time. This career requires confidence, reliability, and graciousness because for most passengers, the flight attendant is the face of the airline.
