They are constantly filling FA positions. There may not be a current class and your resume might be on file pending next class. If no response after 2 weeks to acknowledge receiving your app, I would follow up, then again at 1 month, 2 months, etc.

I would call the HR department, explaining that I am sincerely interested in the position and asking if it had been filled. Human error is always in play and perhaps there is an error on the web site.
