The math is brutally simple: The more time spent en route, the less time spent en suite. That's especially harsh if you really want to get away from it all - say, to the far shores of Vancouver Island (Wickaninnish Inn) or the doorstep of Yosemite (Château de Sureau), among the luxury properties recommended here. By commercial carrier you would spend most of the weekend traveling, wheras by private jet none of these flights is longer than four hours. Prices cover up to seven people and include fuel surcharges and 7.5 percent excise tax. Jet card (JC), fractional, (F) and charter prices are one-way. Fractional prices do not include capital investment and monthly management cost. For additional information and cost analysis, visit Conklin and de Decker Aviation Information (www.conklindd.com).
