I don't believe we should call anyone who goes up in the last year forward who paid their way for a 3 hour trip or less a astronaut. An astronaut in the truest description is a very highly trained nasa or other country scientist/pilot of many years of unique qualifications. A rich mush ass who can't cut their own grass has no qualifications except money. They don't deserve the label astronaut.
Maybe customernaut. Or paidprivilageonaut. Celebrianaut. Or just passenger.
