ATPMBA...
Thanks for explaining the 121 Flag and Supplemental Rules.

However your first sentence, all by itself, would be incorrect (if you would quote rules applicable to domestic air carriers) or in the case of 2 pilot crews of flag and supplemental carriers NOT requiring a third pilot (i.e. shorter flights).

I could also make a single sentence, that would be correct by itself, as follows...
"An airline jet co-pilot minimum qualification is CPL/IR/ME and 200 hrs total experience" (total required for CPL/IR).

All people who are pilots know of this, at least basically, but try to explain that to the general public, as presented by the news media... I can imagine an eager reporter writing "the co-pilot did not even have an airline pilot licence"...
