The key words here are prop planes, turboplanes, and light jets. Prop planes like the Cessna Caravan are popular because they're roomy (the seats are like business class, and often configured face to face). More popular these days are planes like the six- to eight-seater Pilatus PC-12, and KingAirs, which fly faster and feel more like jets. And then you get into light jets like Learjets, Embraer Phenom 300s, and Citation CJ3s, and Hawkers, all of which are sleeker and more streamlined, and can fly for four to five hours, for slightly longer trips.
Those living on the East Coast will soon be able to fly with Beacon, another monthly membership airline, which will begin flying later this summer, starting with 18-20 daily flights between New York and Boston, as well as seasonally in the Hamptons and Nantucket. Memberships start at $2,000 per month (plus a $1000 initiation fee, which will be waived if you join before Sept. 1, 2015).
Customers can choose the cabin layout, including the option to divide the space into separate areas that can be decked out as an office, bedroom, galley or dining area. Exotic wood veneers and hand-stitched leather are among the many accouterments that buyers can select. Lighting and cabin temperature can even be controlled via one’s smartphone. Gulfstream
Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
