A lot of part 135 operations are VIP missions - I know of

What a bunch of BS. Part 121 operations are statisically the
safest form of flying without question.
Those CEOs just don't want to share the plane with the poor
folks. They also want a flightcrew (chauffeur) who will show
them "proper respect".
