Of course, training fees are required to participate in the training. What's there to be wary of? Is there a free lunch in this society?

As for whether you can become a flight attendant after paying so much training fees, it is a doubtful question.

Besides, there are too many jobs that are much better than flight attendants. Twenty thousand dollars can go to college. What you have learned in college may provide you with the knowledge you need at the beginning of your life. Unlike a flight attendant, you may be eliminated before you are 30 years old because of your age.
