People talk line all you need is a degree and a pulse and you will automatically get into a legacy carrier. There are a lot of good, personable, educated pilots here at Atlas with clean records who haven't made it onward yet. 80% of my new hire class is still here. So while hiring is great, the are no guarantees.
Worst case scenario you go to PSA and wind up at A A at 42 years old. That gives you 23 years at American. You can still apply to be a street hire for the entire time that you wait to flow.
