From the Daily Bulletin:

A new service called JumpSeat seeks to pair spontaneous travelers with wealthier individuals and families who have already chartered a plane but want to lower their costs. The idea is to fill seats that otherwise would go empty without greatly changing the experience.

“But you can’t just buy a ticket and board the plane. For now, founder and chief executive Justin Sullivan or one of his colleagues interviews all prospective passengers. The goal: to ensure the extra travelers don’t bother whoever paid $4,000 or $10,000 or $50,000 to charter the plane. Often, that means keeping conversation to a minimum.”
