There's a concept called the "$100-dollar hamburger" in aviation, which is where one takes an otherwise-unnecessary trip for aviation reasons (i.e. maintaining minimum flight time for qualifications, shaking down a plane after maintenance, etc.).

Atlanta -> Savannah -> Atlanta with a 2-hour turnaround could be hundred-dollar hamburger. It might also be two different people using the jet. But... TBH, it might also be that she owns a jet and wants to take a day-trip.
