Those fractional jet ownership really only work out for the business owner looking to profit. They eat out such a markup that it usually winds up being in the best interests of someone to actually purchase the plane outright and hire their own personnel and staff.

They are sold and marketted but its really a sham business arrangement that isn't in the best interest of the person. Ive looked into it myself out of curiosity and realized that if you purchased your own jet and hired your own personnel and were able to get favorable financing, there is no advantage to fractional jet ownership no matter how they try to sell you.

Delta does have a huge advantage in offering a wide scale commercial aviation airline with cost efficient seating. It works out for commercial, but for private jets, not really.
