If it seems like it’s getting more difficult to choose between the many private aviation companies, that’s because they’ve been responding to customer demand to make their membership benefits and lifestyle perks increasingly more flexible and compelling. Today we take a head-to-head look at Sentient Jet and NetJets, two of the industry’s longest-standing and largest businesses.

History & Background

Billing itself as “a more thoughtful way to fly,” Sentient Jet was founded in 1999, and claims to be the originator of the jet card concept. As the story goes, the idea was developed by an entrepreneur and jet owner who was exasperated that his management company wasn’t generating enough charter hours to justify private ownership. Sentient was later bought by private-investment firm Directional Aviation, which gives Sentient the ability to share and glean industry knowledge from Directional’s large portfolio of aviation companies.

Sentient, which Harvard Business Review has called the “Uber of private jets,” has made a multimillion-dollar investment in its safety program, requiring independent operators—the top 20% in the United States—to pass a certification process considered more rigorous than the industry standard. Operators are tested annually, and each aircraft, pilot, and flight is certified. Sentient uses 15 years’ worth of proprietary data to inform its safety oversight program.

The company is also known for its high-end partnerships with events like the Kentucky Derby, Ski World Cup, and celebrities like restaurateur and TV personality Bobby Flay. Its newly developed app allows clients to book in real time and chat with Sentient’s command center 24/7.

NetJets, founded by three retired military pilots in 1964 as Executive Jet Aviation, is the granddaddy of private business jets and fractional jet ownership. Since its inception, it has grown from a fleet of ten Learjet 23 aircraft to 10 types of planes and nearly 700 aircraft worldwide—the world’s largest private jet fleet, all of which it operates itself.

Richard Santulli, a mathematician and former executive with Goldman Sachs, purchased the company in 1984. After poring over 22 years’ worth of pilot logbooks, he crafted an innovative new model of fractional aircraft ownership. NetJets was renamed in 1984 and acquired by Warren Buffet, a NetJets share owner, in 1998, who added it to the Berkshire Hathaway umbrella. In addition to fractional aircraft ownership, NetJets also has several jet card programs.
