Flexjet Orders 300 Phantom 3500 Business Jets in Landmark Move Toward Sustainable Luxury Aviation

The all-carbon-fiber aircraft is currently under design with first flights planned in 2027. The Flexjet firm order is based on deliveries beginning in 2030.

Key Highlights

  • Flexjet's order of 300 Phantom 3500 jets marks one of the largest private aviation deals, signaling a major industry shift toward sustainability.
  • The all-carbon-fiber Phantom 3500 is designed for high efficiency, with features like laminar-flow aerodynamics and the ability to fly on sustainable aviation fuel (SAF).
  • First flights are planned for 2027, with deliveries beginning in 2030, showcasing Otto Aerospace's innovative approach to aircraft design.
  • The aircraft features the world's first ultra-wide 72-inch passenger windows, offering panoramic views at 51,000 feet altitude.
  • Otto Aerospace's new manufacturing campus in Jacksonville, Florida, is supported by a $515 million state incentive package, highlighting significant investment in sustainable aviation technology.

Fractional aircraft ownership and leasing firm Flexjet is the launch customer ordering 300 windowless, fuel-efficient business jets promised by a Texas aviation startup.

Flexjet is the first order of the Phantom 3500 business jets under design by Otto Aerospace. The all-carbon-fiber aircraft is currently on schedule for first flights planned in 2027.

The Flexjet firm order of 300 Phantom 3500s is based on deliveries beginning in 2030. Flexjet is a global corporate jet travel fleet operator which offers partial jet ownership, leasing and jet card services with more than 2,000 clients.

“For 30 years, Flexjet has led through innovation opposed to imitation, introducing tomorrow’s standards, not reacting to yesterday’s expectations,” said Flexjet Chairman Kenn Ricci in a statement. “The Phantom 3500 exemplifies that approach perfectly, marking a bold step into a future where an aircraft’s efficiency and sustainability stand alongside speed, comfort, and range as defining standards. This collaboration with Otto Aerospace further affirms our leadership role in delivering to fractional aircraft owners the future of luxury private aviation.”

Otto Aerospace’s Phantom 3500 aircraft is priced at about $19.5 million per jet. The all-carbon-fiber materials and laminar-flow aerodynamics are touted to streamline the aircraft’s performance and operating costs.

The Phantom 3500 also is being designed to fly on sustainable aviation fuel (SAF), which can cut emissions by 90% and fuel costs by 40%, even taking into account SAF’s higher price per gallon.

“Business jets have long relied on derivative designs built from traditional aluminum structures, aerodynamics, and manufacturing techniques from decades past,” said Paul Touw, CEO of Otto Aerospace. “Freed from legacy systems and guided by a true clean-sheet, ultra-efficient vision for the future, we rethink everything to unlock performance gains once thought impossible.”

When cruising at 590 miles per hour, according to Otto’s design, the Phantom 3500’s emissions performance should be nearly equal to electric vehicles (averaged per seat) traveling at 55 MPH.

And while some aviation observers described the jet as “windowless,” in stories, Otto’s Phantom 3500 is being designed to debut what it calls the world’s first ultra-wide passenger windows, some 72 inches wide each. These reportedly will offer passengers a more panoramic view of the earth’s curvature at 51,000 feet altitude, according to Otto Aerospace’s announcement of the aircraft.

“Flexjet’s decision to build their fleet around the Phantom 3500 speaks volumes about where aviation is headed,” Otto CEO Touw added. “As one of the largest business jet orders in private aviation history, this marks a turning point in the industry’s move toward sustainable and efficient air travel.”

The Phantom 3500 will be built at Otto’s planned manufacturing campus at Cecil Airport in Jacksonville, Florida. The project is partially funded with a $515 million incentive package from the state of Florida.

Texas-based Otto Aerospace, which changed its name from Otto Aviation recently, is made up of leadership formerly connected to industry companies such as Boeing, Lockheed, General Dynamics, Xojet, Bell Helicopter, Hyundai’s Supernal and others.
