Flexjet Orders 300 Windowless Otto Phantom 3500 Jets in Nearly $6 Billion Bet

The deal backs a windowless, laminar‑flow design that still requires flight testing and FAA approval.

Overview

  • Flexjet agreed to buy 300 Phantom 3500s from startup Otto Aerospace, a commitment Business Insider values at nearly $6 billion with deliveries targeted for 2030 after a first flight planned in 2027.
  • The nine‑seat cabin eliminates passenger windows in favor of synchronized high‑definition exterior‑camera displays, while the cockpit retains conventional windows.
  • Otto says a teardrop, composite fuselage optimized for laminar flow and the removal of windows will cut fuel burn by about 60% versus comparable jets, though those claims remain unproven in flight.
  • Published specifications include cruising up to 51,000 feet, an expected range near 3,500 nautical miles, and a list price around $19.5 million, with the company projecting roughly 50% lower operating costs.
  • Otto notes it tested its laminar technology on a full‑scale demonstrator from 2017 to 2020, and both certification hurdles and passenger acceptance of virtual windows remain open questions.
