Excuse me, does anyone know how to apply for a coach attendant? Where can I find a job?

Every coach station has a customer service center. You call there and ask the station staff who is in charge of the arrangement, or directly ask that department to arrange the flight attendant's work. You ask him to call. If he doesn't give it, you say you are complaining, and he will tell you.

It is not easy to do this kind of work well. It is a great test for people to face all kinds of people and deal with many unexpected things every day.

Good luck!
