Someone with private jet cost knowledge should be able to run some numbers really quick:

they have 9 seat jets that cost a certain amount to buy /lease /fuel /service. Assume that all nine passengers travel just once a month and then move to 1.5 times a month, then twice a month and so on. My layman guess is that this is introductory pricing and they might to revise it pretty soon.

*I pay $50 in gas to travel 250 miles with my full size sedan car, so jet fuel alone must be a lot. Another major deal breaker is wait time. Do I have to make reservations 4 months in advance or can I call the same day?
