The career of flight attendants can be divided into four stages: chief flight attendant, cabin flight attendant, regional flight attendant and chief flight attendant. Ordinary students can serve as flight attendants in ordinary cabins after completing the corresponding business training. With the increase of flight hours and the improvement of personal qualifications, you can be promoted to cabin/first class flight attendant through corresponding assessment. After the expiration of the first-class flight attendant assessment, they can serve as regional flight attendants. Excellent regional flight attendants can serve as chief flight attendants after strict assessment by the assessment Committee, and can independently lead the class to perform international flights and chief special plane tasks.
