Regardless of where you come from, the standard still remains. If I won't let my friends and close family ride in back, you don't get a signoff. That issue still seems to remain at regionals, and not majors, but for 121, it is the starting point to even get a checkride in the right seat. Sorry if that ruffles feathers, but that's the standard. Fly SOP and make the appropriate decisions with some common sense and all is well.
