Business airliner can be contracted as bizliner. Airliners converted into business jets are used by sports teams or VIPs with a large entourage or press corps. Such airplanes can face operational restrictions based on runway length or local noise restrictions. They can be the most expensive type of private jet as they provide the greatest space and capabilities.
For those who don't mind mingling with strangers, companies like Tradewind offer shuttles between places like New York and Boston, Stowe, and Nantucket, as well as Caribbean Islands like St. Barth's and Anguilla. (Flights begin at $250 plus tax each way.) The bonus? On a route from from San Juan to St. Barth's, a Tradewind rep will meet you at your terminal and help shuttle you through. JetSuiteX, affiliated with JetBlue, sells seats on planes between Burbank and Las Vegas.
