Two Airbus A380s
The Airbus A380 is the world’s largest passenger jet, and with your billion-dollar budget, you can buy two. The plane has two levels, a 262-foot wingspan and a length of 239 feet. It can hold up to 853 passengers, so bring your friends.
The Airbus A380 is currently used by Emirates, Singapore Airlines and British Airways. Selling at $436.9 million per plane, your pretax bill comes to $873.8 million — not including a 6 percent sales tax — which brings your bill to just over $926 million. You'd have $73 million left over for pilots, fuel and peanuts.
