Both part 91 and part 121 seem to give a lot of discretion
to the PIC, and therefore his crew (including the
stewarde...er. Flight Attendants).

Part 91 rules are out of my league.

Part 91 uses the word "operator," whatever that means.

As far as part 121, that is apparently far out of MY league...
