The BBJ-2 is a BBJ with the longer fuselage of the B737-800. This adds about 19 feet to the length of the cabin.
Boeing is the best-known name of airline-sized aircraft in the domestic corporate marketplace. It is capable of ranges exceeding 6,000 nautical miles but many are ordered without all the available long-range fuel tanks in an effort to increase luggage space. It is apparent that cabin size still sells. It has over 6,600 cubic feet of cabin space that permits passengers to walk from one end of the cabin to the other without going through private staterooms or conference rooms.
With more than 5,500 737s flying with airlines all over the world, corporate operators can expect good support anywhere in the world.
