“Uber for Private Jets” Gets $20m Funding from Jay Z and Saudi Royals

Wow. $9K/year for unlimited private worldwide flights is an incredible deal. I've explored empty leg price specials before, there are even multiple private providers who offer these empty legs through Instagram -- and it's typically at least 9K for one flight (albeit for 6-12 passengers.) Managing the marketplace would of course provide efficiency and a lower price.

Surprised I haven't seen more high end marketplaces, except for at that price many customers expect concierge-level service. Or are there more of these than I have been exposed to??
