Now I'm just speculating here based on her comments. Someone will respond how they were hired back in the 90s with <1000 hrs. But that was then, today...
Sub 2k might be too low for UA. She recommended this guy go to job fairs.
Sub 3k is getting there if you're strong elsewhere in your resume.
>3k is good, except that you're about to retire (fighter guys). But that's the life we chose.
If UA is your #1, go to the job fairs, meet a CP and work at UAX for a decade. Ok, skip the last one...
