These 747 were the first to have the strtched upper deck ( SUD )
747-100BSR SUD:
In 1986, two −100BSR SUD models, featuring the stretched upper deck (SUD) of the −300, were produced for JAL
While only two −100BSR SUDs were produced, boeing did offer the 747-100B SUD but no airlines ordered them.
747-200 SUD:
As on the −100, a stretched upper deck (SUD) modification was offered on the -200.
A total of 10 converted 747-200s were operated by KLM.
747-300:
The −300 introduced a new straight stairway to the upper deck, instead of a spiral staircase on earlier variants, which creates room above and below for more seats.
Minor aerodynamic changes allowed the −300's cruise speed to reach Mach 0.85 compared with Mach 0.84 on
the −200 and −100 models, while retaining the same takeoff weight.
