Overview

• The agreement, unveiled at the UP.Summit in Arkansas, secures 300 aircraft in what multiple outlets describe as one of the largest business-aviation OEM orders.
• Flexjet will integrate the Phantom 3500 into its fleet and its in-house maintenance organization is set to become an authorized Otto service center.
• Otto targets a first flight in 2027 and deliveries beginning around 2030, dependent on FAA certification.
• The super-midsize jet pairs all‑carbon composites with laminar‑flow aerodynamics that Otto claims reduce fuel burn by over 60%, and it replaces most passenger windows with high‑definition exterior‑view displays.
• A Wall Street Journal figure cited by outlets values the 300‑jet deal at about $5.85 billion, as industry observers flag certification and manufacturing risk for the startup program.
