What to Do When Applying?

Hello!

So I am considering applying to be a flight attendant. I am going in to this pretty blind and could use all the help I can get in terms of the application process, the airline with best benefits, what to expect during an interview, etc. I have some piercings and I am assuming that I would need to take those out as well? I’m also curious when applications are available? I have looked online at a few different airlines and none are hiring. Any help would be appreciated! Thank you!
