Best estimate I can find, her flight cost her work about $20,000 round-trip.
I think we're upper-middle-class-ish, but there's no way we could justify chartering a jet for a family vacation if it costs as much as a car (a smaller jet might "only" be around $12,000 for the same trip AFAICT).
Rate for a Gulfstream jet was about $2500 per hour.
So, "for the rich".
