Only thing I’d add to the above is apply as soon as you meet the minimums.
I have known plenty of pilots that took themselves out of the running by saying things like “Delta would never look at me with my experience” or “I’ll apply just as soon as...”
If you want to work here, meet the minimums, apply and then update your app regularly (while building your resume and following the advice above). Don’t let your own doubts be the reason they don’t call you for an interview. Good luck!
