The airport doesn't hire flight attendants, that's done by each airline. Apply to all of them and see what happens. Good luck!
You should go to the specific airline websites and see when and where they are hiring. When I tried to work for United, I had to attend a special event at a convention hall, submit an application, resume, and interviewed on the spot. It reminded me of how models are selected by modeling agencies. Good luck, you have to have the right personality and look.
