Bizliners, or commercial airliners converted for business air travel use, are the 800-pound gorillas of the private jet world. The extremes range from Prince Alwaleed bin Talal’s never-completed ode to aircraft excess, a sprawling Airbus A380 that was to be equipped with everything from a concert hall to a stable for livestock, to Google cofounders Larry Page and Sergei Brin’s Boeing 767-200, which was purchased for a song and transformed into a flying office. These commercial jets, transformed into palaces or spartan corporate workspaces, are among the most notorious—and misunderstood—players in this high-flying microcosm.

The truth about bizliners lies somewhere between those two fabled aircraft. Often dismissed for their bulk, many of these large-bodied jets actually offer two to three times more cabin volume than top private aircraft from Bombardier, Dassault, or Gulfstream while displacing similar footprints. Their aura of extravagance can also be misleading, as commercially designed planes are associated with reliability because they fly far so regularly. Additionally, bizliners not only hold more residual value because they are rarer than standard private jets, they command a premium in the charter space, recouping more cash for owners during downtime.

Despite its plus-sized presence, the bizliner segment constitutes a tiny slice of the market—a low double-digit number of the 700 or so private jets sold every year. Here are our favorites from this small but noteworthy population.
