Social seating hasn't shown a market yet, but nice feature for airlines, not a startup based on it.
Avoiding That Guy, and making sure you sit next to someone who rocks is what SeatID is all about.
SeatID does social seating as a SaaS solution for airlines and travel websites, enabling individuals who opt-in the ability to see who else is on the chosen flight. More than that, it also lets people see who will be on other flights before purchasing a ticket.
SeatID has signed a deal with AeroSvit, Ukrainian Airlines. Which is useful for almost no one if we look at the grand scheme of things.
