Every year, millions of people travel to different places all around the world, using various forms of transportation, but the most commonly used method is without a doubt the airplane. Oddly enough, whenever an ordinary person is asked to list some of the things they would buy if they ever became an instant millionaire or billionaire, a private jet is almost always somewhere on the list. The reason for this is simple, because unlike passenger airplanes, a private jet basically allows you to travel to any destination you want whenever you want, without having to buy tickets, wait in lines, or check luggage. Many billionaires do in fact have their own private jet, and Russian Billionaire Alisher Usmanov has one of the largest and most expensive jets in the world. Usmanov bought an Airbus A340-300 (pictured), which is the largest private jet in Russia and Europe, and he had to pay a hefty penny for it, as this Airbus is currently valued between 350-500 million dollars.
