In brief
- The world’s most expensive private jet is the Boeing BBJ 777-9: approximately 450 million dollars for the aircraft delivered without a cabin, according to several estimates, or about 400 million euros at the rate of 13 October 2026. Boeing does not publish prices for its VIP versions.
- The interior outfitting adds around 100 million dollars, bringing the bill to over 500 million.
- Boeing announces 342.7 m² of cabin space and 11,025 nautical miles (20,420 km) of range: enough to connect any pair of cities on the globe non-stop.
- Launched in December 2018, the BBJ 777X has not yet been delivered to any customer: the first 777-9 is not expected before 2027.
A VIP version of the largest twin-engine jet ever built by Boeing, the BBJ 777-9 holds the top spot in our ranking of the world’s most expensive private jets. No examples are yet in service, but its reference price and performance make it the absolute benchmark of private aviation. Here is what we know about its price, its cabin and its schedule.
How much does the world’s most expensive private jet cost?
Boeing Business Jets does not communicate any rates for its VIP aircraft. The reference figure, around 450 million dollars for a “green” BBJ 777-9, meaning delivered without interior fittings, has been circulating since the programme’s launch according to several estimates. At the ECB rate of 13 October 2026 (1 euro to 1.1188 dollars), this represents approximately 400 million euros.
The final price of a BBJ 777-9 depends mainly on its cabin: entrusted to specialists such as Jet Aviation, Lufthansa Technik or Greenpoint Technologies, it would cost in the region of 100 million dollars according to several estimates, and often takes more than a year.

A 340 m² apartment at 40,000 feet
At the launch in Dubai on 10 December 2018, Boeing Business Jets presented the BBJ 777X as an aircraft capable of flying “more than half way around the world without stopping”. Two versions are offered: the BBJ 777-8, the range champion with 11,645 nautical miles (21,570 km), and the longer BBJ 777-9, which offers the largest cabin at 342.7 m². This is more than the floor space of many mansions, enough to arrange lounges, dining rooms, offices and several bedrooms with en-suite bathrooms.
The aircraft inherits innovations from the commercial 777X: GE9X engines, among the most powerful ever mounted on a commercial aircraft, and 3.5-metre folding wingtips, a first in commercial aviation, which allow the use of the same boarding gates as a classic 777. The cabin is pressurised to a maximum of 6,000 feet, an argument against the fatigue of twenty-hour flights.
Facing the other giants of the ranking
The BBJ 777-9 leads the other airliners converted into private jets. The Boeing 747-8 gifted by Qatar to the United States, which became a presidential aircraft in July 2026, has an estimated replacement value of around 400 million dollars. Roman Abramovich’s Boeing 787-8 was valued at approximately 350 million by the US Department of Justice in its June 2022 seizure warrant. At Airbus, the last published price for the A350-900, the base for the ACJ350, stood at 317.4 million dollars in 2018. The largest purpose-built business jets, such as the Bombardier Global 8000, cost around 78 million.
The price today: an aircraft yet to come
The certification of the 777X has been delayed by several years and Boeing does not plan to deliver the first 777-9 before 2027. Therefore, there is neither a second-hand market nor rental options for the BBJ 777-9. The operating cost, however, is known: Boeing announces 15,050 dollars in variable costs per flight hour, excluding crew, hangarage and insurance. For 400 hours per year, fuel and maintenance alone exceed 6 million dollars. For aesthetics rather than price, discover the most beautiful private jets in the world.
