With a range of 7,700 miles and a maximum cruising speed of 585 mph, the Gulfstream G550 (912.965.3000, www.gulfstream.com) fulfills all the requirements of an ultralong-range aircraft. When it first entered service in 2003, the G550 set the standard for this category by completing a trip from Seoul, South Korea, to Orlando, Fla., in only 14 and a half hours. At just under 44 feet, the cabin is lengthy, and owners can choose from 12 configurations that can include as many as four distinct working and living areas. While the aircraft can seat a maximum of 18 passengers, most configurations accommodate 14 to 16 and include berthing for five or six people. The baggage area is 226 cubic feet and is accessible in flight. The G550 is priced at about $60 million.
