The Boeing Business Jet is a member of the venerated 737 families. The 737s collectively have over 60 million hours of flight time and are still in high demand in the commercial aviation market. The BBJ sold more than one hundred planes in just four years of production, and orders continue to come in. No other private jet offers as much cabin space or reliability. After all, the BBJ is a descendant of commercial aircraft, designed to last decades. The Boeing Business Jet’s full name is the BBJ 737-700 IGW. IGW stands for “Increased Gross Weight,” much of which is due to its massive cabin and increased fuel capacity. The cabin has more square footage than some offices – 807 square feet – and measurements well beyond any other private jet: 79.2 feet long, 7.1 feet high and 11.6 feet wide.
