Anybody know if DAL stiff-arms applicants with black marks on their record? I have an arrest for a couple of misdemeanor traffic violations from my college days 15 years ago, and have gotten intel that Delta won't call me with those on my record. Had my app in for 18 months, and got a fix-it email 17 months ago. I've gone to every job fair in the last year and have 9 internal DAL recommendations on file. Current stats:

1930 TT (all mil)
1655 PIC (F-15 / T-38)
730 IP
3.5 GPA in History at USAFA
3.8 Master's GPA from Air University
No checkride failures
Community volunteerist
previous 3-year non-flying mil assignment in unmanned aircraft
Current T-38 IP w/ 420 flying hrs in last 12 months

Any advice/insight is welcome! Should I look for a different career?
