What Pug also didn't include, are Fedex, UPS, and all the ACMI carriers. Those encompass another 15,000 pilots easily and they are all 121.
I am not sure anyone is ever really confused at when somebody compares NJA to part 121. They are talking about comparable companies in their respective sub industries. NJA is considered the top of the fractional industry, so when you compare 121 to NJA you are comparing top tier 121 companies. I am honestly surprised anyone had confusion about that.
