Two Kings
Clearly, you haven't flown some of these people. I've been on some six day trips where the pax slept on the plane on overnight legs, got up and were met on the ramp by local associates--all wearing business suits. Showers are the new hot option, $970,000 per, to cater to these guys. I know several that fly 600-700 hours a year. At their age, it's about the money and the work.
