Chartered private jet flights can cost thousands of dollars, sometimes tens of thousands, each way. The bottom line depends on several factors, not least of which are mileage and choice of aircraft. But inexpensive chartered flights do exist, costing just a few hundred dollars for the entire plane -- not per passenger. Before your hopes soar too high, know that such rock-bottom prices mean booking an "empty leg" flight. These are scheduled trips but the jets (sometimes turboprops) aren't filled with ticket holders. "If we need a plane in Las Vegas for a charter customer but don't have one there, we may have to fly it there without passengers," explains Alex Wilcox, CEO of JetSuite. The downside is you don't get to pick your route, date, or time of travel. Keep an eye out for a deal that works for you.
