If you're talking about FAA regs, you can't get an airline job without 1500 hours anyway, of which most of that would be from single pilot part 135 or flight instructing. ie, real PIC and not your BS PIC/ICUS which doesn't exist.
Jeez, VH DSJ, if you are gonna brand me as BS, then at least get your facts straight. Have a read on PIC logging time ruling by FAA.

Apparently, what you think as BS PIC/ICUS exists in FAA land. By your logic, all FAA pilots are fraud because they could log safety pilot hours as PIC during their time building.
Double checked on this with FAA FSDO.
