Airline: Orient Thai Airlines
Type: Boeing 747-146B/SR/SUD
In 1986, two -100BSR SUD models, featuring the stretched upper deck (SUD) of the -300, were produced for JAL. The type’s maiden flight occurred on February 26, 1986, with FAA certification and first delivery on March 24, 1986. JAL operated the -100BSR SUD with 563 seats on domestic routes until their retirement in the third quarter of 2006. While only two -100BSR SUDs were produced, in theory, standard -100Bs can be modified to the SUD certification. Overall, 29 747SRs were built, including seven -100SR, 20 -100BSR, and two -100BSR SUD models.
