I remember when Barbra Streisand flew private to DC to go to some Bill Clinton event. Somehow, the price became public: $18,000 for the round-trip.
That was more than twenty years ago.
That means Leonardo would rather fly with the hoi-polloi than part with ~20K. Interesting. I'm sure he went first class though.
Any way we can match the planes to find out for sure? I cant seem to find any pics yet. Will keep looking though.
