With a charter flight, you rent the entire aircraft, rather than just one seat. The aircraft can be large or small, and flights can be one-way or round-trip. The charter could be made on a flight-only basis, might include ground services such as transportation to or from meetings or could be part of a complete vacation package. Charter flights offer more flexibility than scheduled flights, with a wider choice of destinations and tailor-made itineraries.

Fliers with flexibility should sign up for empty-leg email lists of companies like Magellan Jets, who regularly send out emails selling discounted flights from, say, the plane of a corporate exec who flew to Los Angeles but is looking to offset his cost of getting the plane back to New York. “I wouldn’t say that the cost of flying private has gone down, but there are new ways of pricing charter that makes it more accessible,” says David Zipkin, co-founder and VP of Tradewind, the service known for semi-private flights in the Northeast and Caribbean. “In our case, we save people money with our shared charters, and we also sell discounted empty legs.”
Privacy is one of the main advantages of a charter flight.  Unlike a commercial flight, where travelers are herded through a crowded airport, having to undergo an intrusive security screening, passengers on a charter flight depart from a private facility known as an FBO.  At most private airports, passengers can pull their cars right up to the plane.
Members who want to set their own schedule can create a flight and post it to JetSmarter’s app so that other interested members can buy seats for the route and help reduce the cost of the charter; if all the seats on the plane sell, the member who created the flight flies for free. These crowdsourced trips usually top out at $2,000 a person, a fraction of the $8,000 or more per hour it can cost for a traditional charter. “My goal is to make private jet flying less elitist,” Mr. Petrossov said.
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.
