When many people think of private jets, they tend to think of the top-of-the-line executive aircraft put out by companies such as Gulfstream, Bombardier, and Embraer which cater to many businesses, celebrities and wealthy individuals around the world. When it comes to the most expensive private jets in the world though, you may be surprised to see that none of these leading private jet companies make the cut. The ultra wealthy instead focus their attention to converting larger commercial airlines into extremely luxurious and over-the-top private jets that only a select few would be able to afford. Take a look at our list of the top five most expensive private jets in the world:

5. Airbus ACJ 319 Neo – $101.5 Million

The ACJ319neo from Airbus is the latest in luxury private jets from Airbus. Based on the best-selling A320neo (new engine option), the ACJ319neo has all of the advantages Airbus offers in its corporate jets. The ACJ319neo also features new engines, new Sharklets, and a lower cabin altitude with an average equivalent to less than 6,400 feet.

The ACJ319neo series can fly for a range of up to 15 hours, or 6,750 nm, with up to 8 passengers. Their interiors are also customizable, depending on your budget and needs, and allow you to personalize your choice of spacious cabins.

4. Boeing BBJ 787-8 – $224 Million

Capable of carrying up to 25 people, the Boeing BBJ 787-8 has a huge cabin footprint of 2,415 sq ft (138.2 cubic meters). This beautiful Boeing Business Jet comes with your choice of either the GEnx-1B or Rolls-Royce Trent 1000 engines giving it the distinction of a 9,945nm flight range.

The interior cabin is 18 sq ft wide and stays comfortable and quiet thanks to the vibration insulation installed in the cabin as well as a new fan-blade design and engine chevrons. While most commercial airlines usually maintain a cabin pressure of around 9,000ft, the BBJ 787-8 has a cabin altitude of only 6,000 ft reducing jetlag and fatigue for all passengers on board the flight.

3. Airbus ACJ350 XWB – $366.5 Million

Airbus’s ACJ350 XWB (extra wide body) is one of the most technologically advanced VIP widebodied private planes on the market. Boasting a sleek streamlined exterior and an ultra-modern cabin design that allows buyers to easily outfit the plane to their specifications. Airbus has only approved three outfitters, AMAC Aerospace, Jet Aviation, and Lufthansa Technik, to complete Airbus ACJ350 XWB constructions for clients.

The Airbus ACJ350 XWB flies 25 passengers for more than 22 hours, or 11,100 nm, non-stop in 2,905 ft of customizable cabin space. The Aircraft spans a length of 219 ft 2in and has a wingspan of 212 ft 5 in, and yet is still 8 percent more fuel-efficient than Boeing’s 787 models of similar size. The interior options on this flexible aircraft are virtually limitless and depend only on how much you’re willing to spend to deck it out.

2. Boeing BBJ 747-8 Intercontinental – $403 Million

Boeing’s 747-8 Intercontinental BBJ (Boeing Business Jet) is a VIP Jumbo Jet that can be yours today for an incredible $403 Million, and that’s before it’s been fully outfitted.

Typically sold for government purposes or to UHNWIs (Ultra-high net-worth individuals), the BBJ 747-8 cabins are often split into sections for boardrooms, staff areas, bedrooms, lounges, and more. Unlike some of the other aircrafts we’ve covered, Boeing has a list of 15 completion companies that can fully outfit the inside of your new plane to suit your ultimate private jumbo jet fantasies.

1. Boeing BBJ 777-9 – $442 Million

Our last and most expensive private jet is, fittingly, also the most opulent. With 3,689 sq ft of cabin space to accommodate up to 75 passengers, the Boeing BBJ 777-9 is the most recent, and most opulent, edition of Boeing’s 777 series to date. Only one of these series has ever been sold, making it one of, if not, the most exclusive to own planes in the entire world; although, there are currently over 480 orders for them currently in process.
