Haven't flown with an FO hired outside of flow who didn't have a hire date of Spring 2024 or earlier. Used to happen a little more often during the hiring surge post COVID because AA was afraid of UA/DL pouching quality pilots from our WOs. Now that hiring has slowed industry wide there is a larger pool of quality applicants so they are a lot more strict about not hiring outside of flow. There are probably still a few exceptions but not like before. Have you upgraded yet or have any TPIC from a previous job? Doesn't hurt to apply but not something you need to keep hitting refresh on your email.
