On October 11, 1999 Boeing launched the BBJ2, based on the stretched 737-800 airframe, which is 5.84m (19ft 2in) longer than the BBJ, and is offering 25% greater cabin space (and 100% more baggage space), but has slightly reduced range. It is fitted with between three and seven auxiliary belly fuel tanks. The winglets are standard on this version. The first delivery was made on February 28, 2001.
