Is there anyone out there without an internal letter of rec that has received a letter?

I do not know anyone at Delta, yet I am continuing to update my resume via airline apps in the hope of some good luck.

My qualifications include

4250 TT
3900 Jet
1,050 Turbine PIC
5 type ratings
Former part 121, current part 135 PIC
BA degree

Does a guy like me stand a chance? Thank you.
