The most expensive private jet and definitely the most exclusive plane on our list belongs to Prince Al-Waleed bin Talal. An ordinary Airbus A380 is the most expensive commercial aircraft selling at approximately $400 million this year. The lavish customization for the prince will raise that price to over $500 million. So if you have thought that the Prince’s 747 (4th in our list) is outstanding, wait till you hear about the so called ,,Flying Palace’’ the new Airbus A380 will accommodate inside. The plane, which is expected to be delivered this year, is said to have a concert hall, a Turkish bath, a garage for a Rolls-Royce and even a prayer room with electronic mats which automatically rotate to face Mecca.
