I know DL sends regular pilots up to SEA to pick up A/C. Most of the time their families go with them, but paying passengers are not allowed since there are no flight attendants or safety equipment on board. QF probably pays Boeing extra to install fire extinguishers, megaphones, etc. The A/C is usually stocked from Boeing with one roll of toilet paper, one box of Kleenex, one bottle of Softsoap, several box lunches with cold sandwiches and potato chips , cases of sodas and...BEER (usually Heineken).
This plane is built to withstand anything... except a bad pilot.
