Acting as a personal concierge, the app helps hook you up with the perfect jet and route for your destination. The company isn't looking to actually enter into the world of air travel per say, instead choosing to remain more of a tech company and letting the charter companies they work with handle their own planes. And according to Petrossov, no request is too extreme. Someone asked for a flight from Ecuador through Malta and they made it happen, so whatever destination you have planned, it will probably work out just fine.
JetSmarter certainly isn't the only app-based service to offer this; PrivateFly is active in Europe and BlackJet uses a book-per-seat method that uses networking for clients. And of course, even road-based Uber has dabbled in private flights, like when they offered a temporary jet service for people heading to Cannes Film Festival.
