A VIP customer was behind the purchase of two ultra-long range 787-9 Dreamliner airplanes, Boeing announced tuesday at the National Business Aviation Association’s annual convention.

The order, placed in August, has a list price value of $564 million. The VIP customer has requested to be unidentified.

The BBJ 787-9, a business jet version of the technologically-advanced 787-9 Dreamliner, is sought after by customers who place a premium on the jet’s globe-spanning range, spacious cabin and unrivaled passenger comfort. The airplane can fly 9,485 nautical miles while offering amenities such as larger windows, a lower cabin altitude, smooth ride technology, cleaner and higher humidity air, and a quieter cabin.

“The BBJ 787-9 offers our most discerning customers the ability to travel in ultimate comfort and fly directly to just about any city on earth. We’re talking about London to Sydney or Tokyo to Cape Town. Our newest BBJ 787-9 customer can clearly see the possibilities and more,” said Ihssane Mounir, senior vice president of Commercial Sales and Marketing for The Boeing Company. “With a total of 16 orders to date, the BBJ 787 program has won over other government and private customers who want to work, rest, and arrive refresh and ready for a productive day.”
