The ultimate freedom is to buy your own plane. You could own a Bombardier Learjet, for example, for $12 million and it will carry eight people at 530mph for a distance of 2,300 miles or so. But if you want to go transatlantic and carry more people, more quickly, you’ll need to upgrade to something such as a Gulfstream G550, the world’s top-selling inter-continental business jet, which has a range of 7,700 miles and a top speed of 679mph. A new one costs upwards of $53 million. Gulfstream is currently offering a nine-year-old model with 2,000 flying hours and 661 landings under its belt for $28 million – but then, like all aircraft, you’ll need to add the high costs of maintenance, fuel, hangar space, landing fees, pilot pay and depreciation at $2-3 million per year. You can of course recoup some costs by making your own jet available for charter.
